Gearless Traction Elevators
In Gearless Traction Elevators, speeds can be selected as up to 2.54 meters per second. Moreover, hosting ropes are connected to the top of the elevator cabin and surrounded around the drive sheave for motion. The other end of the rope is connected to a counterweight for providing balance and stability to a mechanical system. This type of elevator can be used for tall building designs.
Geared Traction Elevators
This type of elevator can be preferred for low- to mid-rise buildings, the tall of the buildings can be increased up to 76 m. In this application, a gear-type reduction unit is driven with an electric motor, which turns the sheave that moves the ropes. The working speed employed in this design for Geared Traction Elevators is between 1,7 to 2,5 meters per second.
The maximum loading capacity is nearly 13600 kg. Installation expenses of this type of elevator are less than Gearless Traction Elevators have. The system has a brake between the motor and the reduction unit, this brake stopped the elevator motion. All Geared Traction Elevators supplied by ISF Elevator Company exceed all requirements set by the European Standards.
