Commercial Elevator Dimensions

When considering commercial elevator installations or upgrades, it’s important to understand dimensions and ADA requirements.

If you are searching for “commercial elevator dimensions” or simply “elevator dimensions“, this article will help!

Elevator Dimensions

The elevator’s car depth must be a minimum of 51 inches with a width of at least 68 inches. If the elevator features doors that open in the center, though, the mandatory width is 80 inches. Typically, commercial elevators can support anywhere from 2,100 to 5,000 lbs. The inner dimensions must meet one of the two following standards:

  • 5-feet, 8-inches by 4-feet, 3-inches
  • 5-feet, 8-inches by 7-feet, 11-inches

Commercial elevators do not have to have mandated stops, unlike residential elevators.

ADA Requirements

By ADA requirements, all commercial elevators must be in a public space and accessible to all people. Costs of commercial elevators will vary widely by size, with prices ranging from $75,000-$150,000+.

Residential elevators must have the following features to meet ADA requirements:

  • Braile and raised call buttons
  • Required floor dimensions
  • Inside and outside lift buttons with raised braile, verbal and visible signs to indicate directions of the elevator door(s)

Local, State & Federal Requirements

A lot of states and cities that have high-rise offices and residential buildings have laws regulating the design and operation of the elevator. These detail the special safety and assistance issues with elevator fulfillments in taller buildings.

Typically, the specifications for elevator signage are a part of a more thorough set of requirements for the building directory, plans for evacuation, building maps, and directional signage. These cover each of the safety requirements for emergency access, in addition to the requirements to assist individuals with disabilities.

In a lot of cases, compliance to the ADA, ASME, and OSHA regulations is enough for these locations. At Federal levels, OSHA administers the regulations that control the design, construction, and maintenance of elevators utilized by employees. The OSHA requirements include the Car ID and capacity, inspection plating, warning signage for “In Case of Fire and Elevator Out of Order”. They mandate signs for open elevator shafts also, and exposure to possible dangerous electrical and mechanical parts. OSHA regulations also have a requirement for the distinction between freight elevators and ones meant for people.

How Does an Elevator Work

How Does an Elevator Work?

Elevator installation is a developing business, yet change is in the works as office space and energy cost increase. A lot of buildings taller than 4 stories make use of traction elevators. A motor located at the top of the shaft rotates a sheave—basically a pulley—that lowers and raises cables connected to the elevators cab and its counterweight. Gears attach the motor and sheave in slower elevators. Faster elevators have no gears; the sheave is directly coupled.

Nonetheless, the machinery usually packs an entire room above or on the side of the top of the shaft, taking over what might be excellent penthouse space. But developments are enabling builders to stuff the equipment into the head of the shaft or beside a side wall. Many companies are utilizing permanent magnet gearless motors, that are smaller than conventional designs but have grown to be just as strong.

Having said that, today’s manufacturers are taking advantage of gravity for energy savings. A counterweight selected to weigh about the same as a cab with 40% to 45% of a full load reduces the motor output required. However, if an empty elevator needs go up, the heftier counterweight’s fall gives too much energy; enormous resistors disperse the leftover energy as heat. The equal resistance is required when a full cab (heftier than the counterweight) is going down. Newer regenerative drives, nevertheless, turns the dissipated energy into electricity. The energy then gets fed back into the building’s electrical system for re-use.

Advanced dispatch technology is raising human efficiency in buildings that have multiple shafts. Office buildings are stuffing more people into floors that already exist; however, the increased populace may slow elevator service. For compensation, installers are switching the “up” and “down” buttons in lobby’s with display screens that are numbered or touchpads. Potential passengers push the floor number that they want, then a computer informs them which elevator to get on, putting people in groups going to the same or adjacent floors. The computer dispatches the elevators so that each one goes to a small set of neighboring floors, rather than randomly going far upwards and downwards. The system decreases wait times and energy use.

How Much Does Elevator Maintenance, Repair or Replacement Cost
Written by webtechs

How Much Does Elevator Maintenance, Repair or Modernization Cost?

The average cost of elevator maintenance is about $370. On average, elevator repair and maintenance costs ranged from $170 to $2,000 in the US for 2019. The most common price range for elevator repairs is from $170 to $600.

  1. AVG National Cost: $370
  2. Typical Costs: $170 to $600
  3. Low Costs: $120
  4. High Costs: $2000

Whenever you are deciding to install an elevator or purchasing a building that has an existing system, one thing that should be considered is the long-term costs that come with the maintenance. Elevator repairs can range between $170 to $600, which can cost an average of $370. The overall price may be as low as $120 or it can be as high as $2000.

If there needs to be a full elevator replacement, then the price could range between $11,000 to $21,000, depending on the number of floors it travels to and the type of drive.

Having regularly scheduled maintenance can help to keep you from having a major fix. This may cost between $220 to $320 a year for semi-annual to annual maintenance. You may also modernize aging elevators which increase the lifespan, update the function and look, and minimize any ongoing repairs. This is cheaper than having a complete replacement.

How Much Does An Elevator Service Call Cost?

The average service call cost for most elevators is around $150. If there are any needed repairs, then the cost of labor to repair the elevator will be around $80 per hour. Then the certification of safety and inspection fee will vary based on the area which comes out to about $200 for an elevator.

Many maintenance companies will be able to handle routine maintenance, inspections, repairs and safety testing. Most manufacturers will recommend using the company that installed the system for repairs and maintenance. There are some companies that are factor authorized and will provide needed repairs using original manufacturer parts.

How Much Does Elevator Modernization Cost?

The cost for modernization will range between $250 to $350 in order to upgrade the railings and fixtures in the cab and between $8500 to $15000 to replace the control system. If your elevator isn’t working right or you want to make it more energy efficient then installing a new piston or motor will cost between $10,500 to $15,500.

There are many benefits for elevator modernization:

  • Minimized vibration and noise
  • Updated feel and look
  • Reduced calls to a service company
  • Improved reliability and safety
  • Smoother ride
  • Faster ride
  • Reduced wait times
  • Improved energy efficiency

If you are considering elevator modernization, read these factors first.

How Much Does Elevator Repair Cost?

  • Motor Replacement: $12,000
  • Piston gripper installation: $15,500
  • Replace controller wiring: $4,500
  • Cab Wiring: $4,500
  • Cab operating Panels: $4,500
  • Traveling Cables: $3,500
  • Piston: $3,500
  • Replace landing entrance doors: $3,000
  • Door hardware (Mechanical): $1,500
  • Door Hardware (electrical): $1,000

Most Common Elevator Repairs & Service Requests

  • Electronic glitches: Newer systems can be outfitted with computerized or automated controls that could have glitches, which interfere with system performance.
  • Drive chain adjustments: This helps to make sure that the chair lift stops, or that the elevator opens at the right place.
  • Seal maintenance and cleaning: this is for pneumatics.
  • Fixing ruptured hydraulic fluid lines within a hydraulic system.
  • Replacement chain for a chain drive system.
  • Replacement cables for a hydraulic system or cable drive.
  • Malfunctioning door operators make up nearly 75% of elevator service requests.

Full Elevator & Part Replacement Costs

Full replacement could cost over $20,000 so it needs to be considered against the expense of any repairs. Depending on the age of the elevator, the continuing maintenance can get expensive. There will be a point, that it will make more sense to replace some major parts instead of repairing them. A new elevator will last up to 30 years. One that has the drive system which is cables, motor and pistons as well as controls replaced will last between 20 and 30 years.

Common Elevator Problems

Elevators are prone to various issues related to the functions. Some of the common issues may include elevator not working, the call box not working, bumpy or jumpy rides, device getting stuck and odd noises. Property owners may even notice that there is high energy use, increased down time and slow operation. Lack of maintenance could increase the frequency of elevator problems and system breakdowns.

  • Stuck on a single level: This could be because the door open sensors are activated when the door closes. Check for obstructions on the sensors.
  • Slowing: Technicians can troubleshoot this.
  • Noise: Service companies are needed to find the cause.
  • Doors: These may get stuck. Make sure that you check for any type of obstruction before you call a professional.

Repair your c elevator with the help of a professional

DIY Elevator Repairs and Maintenance

Elevator Repair

Elevators are complex machines and it is highly recommended that you don’t do any repairs on your own. The repairs should be done by a certified disability services professional. However, there are some things that you can check on your own before you call a service company.

  • Latch for the outer door: This door at the floor exits may be obstructed.
  • Door obstructions: Check the track to make sure nothing is blocking it from closing right.
  • Reset Switch: There may be a built-in switch that can restore power.
  • Check the fuse panel or circuit breaker: You want to make sure there is still power. Some elevators are designed to travel to the bottom floor and open the door using battery power whenever the main power goes out.

Beyond these easy repairs, service companies will need to be called because of safety factors that are involved and specific technical knowledge is needed.

How long will an elevator last?

An elevator can last between 20 to 30 years with routine maintenance.

Things to consider for elevator repairs

When you are investing to fix an elevator, there are a few factors that should be considered:

  • Possible increase in the resale value of the home
  • Peace of mind and increased safety
  • Anticipated length of ownership

Factors that may affect the cost of repair for an elevator:

  • Type of drive mechanism: Hydraulic systems are more expensive than vacuum or pneumatic driven.
  • Number of stops or floors
  • Manual versus automatic door opener

Elevator Insurance and Warranty

Lifts and elevators will normally have a warranty period which is normally a year after the device has been installed where the labor and parts will be covered. This could be followed by another year which the manufacturer will cover the price of the parts, but the owner is responsible for labor.

Lowering the impact of expensive home repairs may often justify the price of home warranties, but you want to check with your carrier to ensure that your lift or elevator will be listed within the warranty. You should also check with your home owner’s insurance to make sure that your lift or elevator is listed within the policy or insurance may not cover replacement or repairs if there is major damage to the unit. Some health insurances and/or Medicare may cover some expense for installing the lift in your home. If your doctor prescribes a lift, then it may be considered to be needed durable medical equipment. Check with your health insurance to see if this would be covered and what part of the price it will cover.

There are many seniors who are looking to spend their retirement years in their current home. You should meet your mobility needs with options that are right for you. There could even be grants available to make the needed modifications to your home.

Commercial Elevators

Commercial elevators will have more considerations.

Higher Traffic: This is because it is in a public space and it will normally see more traffic, so they will require more repairs and maintenance frequently.

Regular inspections: The frequency of this may be determined by the state or area you live in, but it is normally done every year. Residential systems may not need an inspection, or it could just need an inspection when it is installed. Check with your local area or call a professional for the needed requirements in your area.

Code Requirements: Whenever it is installed within a commercial or public space, there will be strict building codes and ADA requirements. Upgrades or repairs may be needed to meet these codes. The same type of requirements may not always apply in a residential situation. You should check with a local elevator service company for more information.

Elevator Not Working - Common Elevator Breakdowns
Written by webtechs

Elevator Not Working | Common Elevator Breakdowns

If you are searching for content related to “Elevator Not Working” or “Common Elevator Breakdowns“, this post should help! Here we list the most common elevator breakdowns and reasons why your commercial elevator isn’t working.

There are various reasons elevators might malfunction, from warn sheaves to old operating systems. At Renown Electric our team is always ready to assist.

There are often ways to prevent equipment failure with the proper inspections and preventative maintenance. Not only will productivity be increased with regular maintenance routines, as it avoids extended downtime, it has shown to lower overall energy computation up to 15%.

A clear sign of wear includes inconvenient, frequent breakdowns and longer wait times. Issues that are less obvious include low power, higher energy use and overheating, but these increase hidden expenses. By implementing an easy elevator motor maintenance routine, you can reduce the downtime and expenses in the long-term.

Common Elevator Breakdowns That Leave Elevators Not Working

The following are some of the common issues with elevators, and methods for preventing downtime:

Worn Sheaves

Additional wear is placed on ropes due to worn sheaves, this will raise the amount of wear on sheaves as well. Therefore, causing damage to both parts, instead of just one part.

Depending on the damage done, sheaves can be regrooved, otherwise replacing them will assist in preventing early failure of the hoist rope. You should ensure the grove profiles are checked, verifying the fit between sheave and ropes are proper. There are tools that have magnetic standards with straight edges for visually checking the sheave grooves, ensuring they are wearing evenly.

Solution – Regrooving the sheave

Power failure

An elevator requires a good amount of energy, usually obtained from a commercial building utility system. This means that an update of the system voltage is able to impact the motor operation, and has the potential of damaging the elevator system. Therefore, a power quality survey is recommended on any elevator that has history of operation problems or motor failure.

A drastic change in temperature can be determined using infrared thermography equipment, which is used for identifying potential issues prior to becoming expensive system failures. Some of the more common issues include under/over voltage, which can be spotted easily using power quality surveys, along with fuses which run hot that infrared imaging equipment can detect prior to motor failure.

Solution – Infrared inspections


As things wear down, other parts can become contaminated form small metal particles that get released within the oils, potentially interfering with the elevator system functioning properly. In a similar manner, worn seals or improper lubrication is able to result in contamination issues. To avoid contamination becoming a larger issue, an oil analysis should be conducted to determine if there are any signs of wear or contamination within the motor.

Premature wear of the crown gear (found on geared elevators), along with higher concentrations of aluminum within the hydraulic tank can be detected from the analysis, including a high amount of bronze within the gear case oil, all indicating issues.

Solution – Lubrication and oil analysis

Noisy bearings or bearing malfunction

More than half of all elevator motor failures occur due to bearing malfunctions. It is common for noisy bearings to be caused from motor vibrations. Although variable frequency drives can assist with lowering the energy use of the motor, it introduces common mode current, which increases the vibrations and becomes a dangerous byproduct resulting in potential premature bearing wear. This can become high risk.

As a way to address this issue early, an inductive absorber should be considered for absorbing the stray currents while protecting the elevator system from the chance of breakdowns. In addition, make sure ground are all securely connected, minimizing issues from electrical noise from the ground which could trip the system, or result in false system counts.

Solution – Inductive absorbers

Misaligned motor drive

When electric motors are coupled with other equipment, it is important the shaft alignment is correct. If the alignment is not correct, motor bearings will wear quicker. To detect shaft misalignment, there are a couple methods. First, is a straight edge and string can be employed. Another is using advanced laser measuring equipment.

Additionally, the purchase of geared machines equipped with flange mounted motors can be considered, as they do not require the alignment corrections if the machine has to be disassembled.

Solution – Motor alignment

Different Types Of Elevators
Written by webtechs

Types Of Elevators

If you are looking for the different types of elevators installed in commercial facilities, this post should help!

There are various types of elevators for various building types. Elevators will carry people and other items that need to be taken to various levels of a building, within a certain weight capacity. During the 1850s, the structural frames were being built using a taller structure to them and then elevators became a very common thing. What made elevators so popular was the unique safety mechanism made by Elisha Otis. Nearly all of the modern buildings that have more than a single floor are required to have access to the other floors by means of more than just the average stair.

Types Of Elevators

The 6 type of elevators that are used the most. Each of the types will have differing variations:

Geared & Gear-less Traction Elevators W/ Machine Rooms

  • Geared Elevators
  • Gearless Elevators
  • MRL Elevators

Geared elevators and gearless traction will use ropes to lift them. The ropes will pass over a wheel and the wheel is attached to an electric motor that is located on the top of the elevator shaft. These are often used for mid-rise to high rise elevators and will have faster travel times than your hydraulic elevators. These elevators will use a counter weight which will make them more efficient to run du to the offsets of the weight within the car elevator which include the passenger weight, which takes extra work from the elevator. Elevators that are using geared traction will use a gearbox that is attached to the motor. The gearbox is what will drive the wheel and move the ropes. Elevators that have this geared traction will have the ability to move up to 500 feet per minute. The maximum travel distance for geared traction elevators are only around 250 feet.

Elevators that have gearless traction will have a wheel that is directly attached to the motor. Elevators that have gearless traction will have the ability to move up to 2000 feet per minute. The maximum travel distance is 2000 feet which actually make them the only ones that can be used in high rise buildings. The elevators that have gearless traction are a bit high when it comes to the initial cost, while maintenance costs stay at a steady medium, and they are often more efficient that geared traction elevators. Checking the traction for the elevators sheaves and ropes for wear and tear regularly is vital. These will wear the traction between the cables and sheave will reduce which causes slippage and it will continue to slip more which reduces the efficiency of the elevator and makes it more dangerous to use.

Elevators that have traction will have restriction on height, as they are decided by the elevator cable/rope length and weight. There are newer materials that may be used for traction elevators which make them stronger but lighter and the material is carbon fiber which will let the elevators reach newer heights.

No Machine Room Elevators or MRL

A MRL or No Machine Room Elevator is just another way to say traction elevator that doesn’t have a machine room over the elevator shaft. It is located in the override space. Whenever it needs repairs, it will have to be accessed through the cab of the elevator which is at the top of the elevator. The control boxes are in the control room and this is located at the highest landing which is about 150 feet from the elevator across from the elevator shaft.

Having a maximum travel distance of 250 feet, a machine roomless elevator will have speeds of up to 500 feet per minute. The MRL as well as geared traction elevators will have similar start up costs, and maintenance costs, but the MRL elevator will have a lower energy cost than the geared elevator. Gearless traction elevators and MRL elevators are almost equal in energy efficiency, they are reliable and take up less space, but the MRL elevators are best and more popular for mid-rise buildings that have a travel distance of 250 feet or less.

One of the biggest reasons that the US has been slow to adopt MRL elevators is because of building codes that have provisions about the motor being located within the hoist way of the elevator. These codes are being slowly changed, but it is in your best interest to consult local authorities about certain MRL elevators.

Hydraulic Elevators:

  • Holed Elevators
  • Hole-less Elevators
  • Telescopic Elevators
  • Non-Telescoping Elevators
  • Roped Elevators

A hydraulic elevator has a piston that is found at the base of the elevator to support it. The piston will then shove the elevator upwards while the motor moves an oil or hydraulic fluid into the piston. While the elevator descends the fluid is released trough a valve inside of the piston. These elevators are normally used in buildings that have no more than 8 floors and it only travels at 200 feet per minute.

On the lowest level, across from the elevator will be the machine room. This type of hydraulic elevator will have a sheave that extends under the floor of the elevator to the pit of the elevator, and while it is descending, the sheave will accept while pistons retract. Several configurations will have a telescoping piston that will collapse which requires a shallow hole under the pit.

The maximum travel distance is about 60 feet. The hydraulic elevator that is holeless may have the piston on either side of the cab. For this particular configuration, the telescoping piston has been fixed in the pit, so it won’t need a sheave or a hole in the pit. Telescoping pistons will let the elevator travel 50 feet, where the non-telescoping piston will go up to 20 feet. There will be a combination of ropes with a rope hydraulic elevator where the piston moves the elevator which has a travel distance of only 60 feet.

The initial cost for this elevator will be lower as well as the maintenance costs when you compare it to the costs of other elevators. The hydraulic elevator will also use more energy than other elevators and that is because the electric motor is working against gravity while forcing hydraulic fluid into the piston. There is a drawback of having the fluids sometimes leak which can cause a hazard for the environment. The main reason that hydraulic elevators are not popular is because of past environmental risks that were involved with the energy use being really high.

Pneumatic Elevator

These types of elevators are lowered and raised by air pressure. By physics, the air pressure difference between the below area and the above area of the elevator cab creates a vacuum that will transport the elevator by air. It is the turbines or vacuum pumps that pull the elevator up and release the air to let the elevator go down. Pnuematic elevators are great for homes as they are designed compact. They do not noise a hoist way and you don’t need to excavate a pit.

Climbing Elevator

A climbing elevator holds its own power device, most are combustion engine or electric driven. These types of elevator are mostly used in construction or work areas.

Industrial Elevators

  • Hoist Elevators
  • Incline Elevators

Industrial elevators are designed to hoist large amount of weight. Industrial elevators are usually incline and hoist elevators. These types of elevators are mostly used in shipyards, warehouses and construction.
