Elevator manufacturing is a complex process that involves various components to ensure the safe and efficient operation of elevators. These components, manufactured by specialized elevator parts manufacturers, play a crucial role in maintaining structural stability, enhancing passenger comfort, and ensuring safety measures are in place. For businesses procuring or using these precision manufactured products, it is essential to have advanced knowledge of elevator components to ensure reliability and efficiency. In this article, we will delve into the different components involved in elevator manufacturing, providing industry professionals with practical insights and in-depth knowledge.
Different Components of Elevator
There are several key components used in a elevator. Some of the major components are discussed below.
Elevator Car Components
The elevator car is at the heart of any elevator system, responsible for transporting passengers or goods between different levels. It consists of several key components that work together to ensure structural stability and safety.
- Car Sling: The car sling acts as a load carrier within the elevator system, isolating vibrations during operation. It can be of two main types – suspension (1-1) and (2-1), with or without a braking system.
- Upper Transom: The upper transom serves as a support element within the car structure, holding roller guides or sliding shoes. It also includes braking system catch clamps for added safety.

- Lower Transom: Acting as the flooring carrier of the car, the lower transom incorporates pressure springs for isolation purposes. The presence of safety gear catch clamps and a shearing linkage system further enhances safety.
- Side Frame: The side frame connects the lower and upper transoms, providing structural stability to the elevator car. It ensures that all components are properly aligned and securely held together.
- Elevator Cabinet: The elevator cabinet encompasses ceiling, walls, and floors that cover the interior space of the car except for emergency trap doors, car doors, and ventilation apertures. It provides a finished look to the elevator car and ensures passenger safety.
Mechanical Accessories
Several mechanical accessories play a crucial role in the smooth operation of an elevator system, including doors and door operators, as well as guide shoes.
- Car Door and Door Operator: Elevators can have different types of doors, such as single slide, two-speed side opening, single-speed center opening, or two-speed center opening doors. These doors are operated by specialized door operators that ensure smooth and reliable functioning.
- Guide Shoes: Guide shoes are essential components that guide and balance the elevator car along guide rails within the hoist way. They prevent any lateral movement of the car during travel, ensuring a safe and smooth ride for passengers.
Traction System
The traction system is responsible for providing motion to the elevator car through hoist ropes. It comprises key components such as the traction machine and car cables (ropes).
- Traction Machine: The traction machine consists of a motor, drive sheave, brake, and machine bed plate. The motor turns the drive sheave which moves the car through hoist ropes based on the desired direction of travel.
- Car Cables (Ropes): Car cables or ropes provide support to elevate and lower the elevator car within the hoistway. The number of lays or strands in these cables depends on factors like load capacity and speed requirements.
Control System
The control system plays a vital role in regulating elevator operation and ensuring efficient performance.
- Elevator Controller: The elevator controller is responsible for controlling various functions within an elevator system, whether manual or automatic. It regulates the voltage supply to different components and fixtures, ensuring proper coordination.
- Drive Unit: The drive unit, powered by Variable Voltage Variable Frequency (VVVF) drives, provides motion control within the elevator system. By regulating the electricity supplied to various components, it enables smooth acceleration and deceleration, contributing to passenger comfort and energy efficiency.
Safety Systems
Safety systems are crucial in preventing accidents or major failures within elevator systems. They include safety brakes and safety devices that ensure passenger protection during emergencies or speed limit violations.
- Safety Brake: In case of cable failure or other emergencies, safety brakes engage with metal teeth embedded in guide rails to prevent the elevator car from crashing to the ground. These brakes provide an additional layer of protection for passengers.
Safety Device: Safety devices are designed to protect passengers and goods during emergencies or when speed limits are exceeded. They monitor various parameters such as overspeed, leveling accuracy, door operation, etc., triggering appropriate actions to maintain safety.
