Elevator drive systems

​

Thanks to the improved control structures, hardware and other automation systems in traction elevator systems, most of the manufacturers are producing energy-efficient elevators.

The drive system of the elevators is groundbreaking with all-the-time improvements, applying new technologies that aims at energy saving, operating afely and reliably, reducing environmental pollution and noise pollution, and reducing maintenance costs.

For mid and high-rise buildings, traction or cable-driven type of elevators are perfectly suitable, compared with unsuitable hydraulic elevators.

Types of elevators

1. Hydraulic elevators

2. Cable driven or traction elevators

In an elevator, car is raised or lowered within several floors of a commercial and residential building. Depending on the requirements, the load and the area of application, these elevators are installed with rated capacity and rated speed.

Hydraulic elevators

Hydraulic elevators are simple and effective in which the force required to move the car is low compared to the other elevators, but its application is limited for low stories buildings, and high costs for maintenance and component replacements.

Traction elevators

Nowadays, with the advantages of high speed to very high speed, smooth car operation, and unlimited height are the basic characteristics of the elevators using traction machines and cable-driven system.

Traction machines that are used for elevators can be either Gearbox or Gearless. Which machine type can be applied will depend on the structure of the building and the hoist or the shaft.
