What Are the Elements of an Lift’s Construction?

The operation of lifts is based on a very simple principle, despite the fact that the technology behind them dates back hundreds of years. Even though the fundamentals of lift engineering haven’t changed all that much over the years, there have been some minor adjustments made to make the ride more comfortable, and the effectiveness of the lifts has been improved through the use of computer control systems to make transportation more expedient. Let’s take a more in-depth look at the components of this construction and lift spare parts, that helps you move up and down and the roles they play.

Car and shaft of the lift

The lift shaft encloses the lift car, which can hold people or objects for transport and is located within the lift. Lift cars can range in size from small to large, always come with at least one door, and can be raised and lowered using either a motor or a hydraulic system. Buildings typically have motorized lifts installed because they are the most convenient and cost-effective option. Lift shafts also house guide tracks for the lift itself and the counterweight, both of which contribute to a reduction in the amount of strain placed on the lift motor.


This is the primary section of the lift, that is also called lift car and is intended for the transportation of goods and services as well as the movement of people.


Lift doors, just like regular doors, serve both as entrances and exits to the building. There are two distinct varieties of lift door: manual doors and automatic doors. Manual door type require the assistance of the person who is trying to enter the lift in order to be opened. Automatic doors are a type of door that can be opened without the need for a human to push a button because they are powered by something called a door operator.

Governors of speeds

The term “speed governor” refers to the component of lifts that controls the speed of the vehicle. If the lift is traveling at a speed that is greater than the maximum allowed, the speed governor will slow it down. In most cases, it will be fastened to the underside of the car and will also go by the name governor rope.

The sheave as well as the motor

In motorized lifts, the raising and lowering of the lift car is accomplished with the assistance of steel ropes that are attached to the lift car in addition to a counterweight. To assist in reducing the overall strain placed on the motor, the counter acts as a simulation of the weight of the lift car when it is operating at 40 percent capacity. The sheave is nothing more than a pulley that has groves and is responsible for moving the rope in order to raise and lower the lift. The sheave is moved by the motor in the direction that the lift must travel in order to transport passengers from one floor to another.

Control unit

The control room, which is typically situated on the ceiling of the lift shaft, is where the control unit, along with the motor and the sheave, are kept. It is responsible for translating the signal that is sent from the controls on each floor into either an upward or downward movement for the motor. The control will receive a signal to stop it once the lift car has arrived at its destination. This will allow passengers to enter or exit arrived car. A computer is also integrated into the control unit, and this computer is used to monitor travel patterns as well as specific instructions that have been programmed into it regarding rest locations and signal priorities.

Along with the guide rails, the counterweight

In an lift, the counterweight works in a manner analogous to that of a child’s seesaw in that it generates a constant amount of energy that can be used to raise or lower the lift car. This helps to alleviate the strain that is placed on the motor. In order to move the lift car in either direction, the motor will either use the counterweight or the lift car itself. Both the lift car and the counterweight have their own set of guide rails that prevent them from swaying in either direction, resulting in a ride that is smooth regardless of which way the lift is traveling.


The buffer is a piece of protective equipment that can be found at the base of the lift. Its purpose is to keep people safe. It is possible for buffers to halt a falling car by either accumulating or dissipating the kinetic energy that the car possesses.

Protective measure

Because of the importance of passenger safety, this contraption is affixed to the lift. In the event that the lift travels downward at the maximum speed or over the speed limit, the safety device can maintain a safe and secure traveling environment for the passengers.
