Elevator Maintenance

elevator maintenance

Vertical transportation happens to be an expensive investment in any commercial establishment, costing hundreds of dollars for a medium-sized structure. As a business owner, you would be looking for elevator maintenance services at an affordable price. An elevator is a highly complicated device with hundreds of moving parts that must be kept in good working order. One of the functions of maintenance is to ensure that equipment continues to work by preventing excessive wear and breakage.

Business owners would want the elevators to work as it was designed. Only skilled, trained personnel with the proper equipment and instruments can carry out necessary maintenance.

Checklist for maintaining an elevator

Your building’s elevators should continue to provide safe and dependable service to your tenants as long as they are kept in good operating order. However, not all property owners prioritize elevator maintenance and inspections as much as they should. One of the primary causes of accidents with this equipment is a lack of basic care. Routine inspections are necessary to help assure the highest levels of elevator safety.

The key to a good inspection is to have a strategy in place and to stick to it. As a result, for maintaining an elevator, the checklist is a very helpful tool for anybody in charge of home elevator maintenance.

The emergency stop button, for example, is an important but tiny component within the car. It might be disastrous for everyone riding if this is not checked as part of routine lift maintenance. Another essential step is to ensure that the pit area is clear of barriers, especially since elevator installation and repairmen have the highest accident rates among building workers.

The inside of car

  • Inspect the elevator car’s interior for damage to the walls, ceiling, and handrails.
  • Inspect the position of indicator lights and replace any that are burned out.
  • Check the levelling accuracy, acceleration, and deceleration of the elevator as it goes up and down. Make any adjustments that are required.
  • Make sure that the door glides open and closes smoothly without slamming or bouncing.
  • Check that the door restrictor is in working order and make any necessary repairs.

The outside of car

  • Examine the hall stations and lights, and replace any that are burned out.
  • Examine the door panel as well as the clearances.
  • Put the firefighters’ service in Phase 1 to the test.

The machine room

  • Make sure there are no non-elevator-related items in the machine room.
  • Look for leaks, strange vibrations, or wear on components.
  • Look for signs of overheating or failure in electrical components.
  • If necessary, clean the circuits.
  • Make sure the oil level is correct.
  • Make any necessary changes or arrange for follow-up service.

The top of car

  • Ensure that the halt switch and inspection station are in working order.
  • Clear any trash from the car’s top.
  • Look at all visible components, such as rollers, guide rails, and leveling mechanisms.
  • Inspect the connectors and check for wear on the traveling cables.
  • Examine the door operator and all of its parts.
  • Look for signs of rodents, fire safety, and vandalism in the hoistway.

The pit

  • Check to see if all the electrical equipment of the elevator is working properly.
  • Clean the pit and inspect it for leakage.
  • Check for corrosion, alignment, and secure attachment of the spring buffers.
  • Examine all viewable elements, such as rollers, guide rails, safety devices, and switches.
  • Look for wear, pinches, and snags in the travel cable.
  • Inspect whether the sewage system is clean and working properly.

Follow all the recommendations as mentioned in this post to maintain both home elevators and commercial elevators. Maintaining the elevator is extremely crucial to avoid unforeseen situations. Most importantly, it prevents disruptions at your place while ensuring a longer lifeline for the elevators.

Where Does The Escalator Get Its Energy From?

Where does the escalator get its energy from?

When it comes to the usage of power, all escalators are not made equal. The larger an escalator is, the better it rises and the wider its steps are, the more energy it would consume. In terms of the number of visitors it receives, it also makes a difference.

Escalators, like elevators, have a wide variety of power usage options. According to a consultant, a typical escalator in a shopping mall, which has a 7.5 horsepower motor, rises 15 feet above the ground and is kept working 14 hours a day, six days a week could use around 7,500 kilowatt-hours. Now, you might be wondering where does the escalator gets its energy from?

Things you should know about escalators

  • Usually, escalators operate at a constant speed, unless you slow one down to cut down your energy bills. As more people board up an escalator, the motor will have to work harder to keep everything going at the same speed. The motor consumes more electricity because it pulls a greater current.
  • In the case of a down escalator, the current and power used decreases as passengers board them. When occupancy is detected, sensors activate the escalator, which runs for a defined amount of time after the person has arrived at their destination.
  • The most proficient method to transport big groups of people is to use escalators. Airports, bus and train stations, commercial and office buildings, shopping malls, hotels, hospitals, universities, and government buildings are all examples of where they are employed. The energy consumption of an escalator is determined by the step width (which is related to the peak load carrying capacity), traffic patterns, control type, annual running hours, and vertical increase. A 15-foot-high shopping center escalator that runs 14 hours a day/6 days a week might utilize 4,000 to 10,000 kWh per year. A 20-foot rise on a larger escalator in a hotel or convention center, a machine that runs continuously may use 31,000 kWh per year. An escalator with a 35-foot lift at an airport might require around 60,000 kWh per year.

How to conserve energy while operating escalators?

  • There are various methods for conserving energy while using escalators. Stop-and-go operations are possible when there is little or no traffic. When the elevator is not in use, it turns off. Again, it turns on when the pressure mats, photocells, or infrared beams detect the presence of a passenger. The elevator must have a soft-start feature so that it can gradually increase to its full operational speed. Building codes may prohibit this kind of operation, and it is frequently discouraged due to liability concerns. Those who come across a stop should be aware that it is a sign of an impending issue. When people see an escalator that isn’t moving, they often assume it’s broken.
  • Slowing down the elevator when there are no passengers is a viable option. Energy savings of 15% to 40% can be achieved by installing variable speed drives or using variable voltage motor controllers. With medium traffic, this option is handy. On extensively used down escalators, regenerative braking can be used, and LED light sources can be placed for skirt guard, comb, and rail illumination. Improvements in lighting alone can save between 1,600 and 2,000 kWh per year.
  • Escalators do generate some great scope for the purpose of saving energy if one can make out how to reduce energy consumption when they move along without any load. Motor efficiency can be regulated by controlling the escalators.

Of course, escalator get their energy from the electric connection of the building. The overall consumption largely depends on a number of factors, as discussed in this post. Also, there are different ways to cut down this energy consumption.
