Engine - geared or gearless, with or without frequency conversion and drive sheave. Controls the movement or the halting of the lift. Choosing the right drive solution is the prerequisite for the lift system's cost-effective operation and its performance.
Types of drive:
Worm gear
Transmission and power transfer between engine and drive sheave via a worm gear (worm roller + spindle).
Exceeds even the most elevated expectations regarding travelling comfort, swift and accurate docking – on all loading conditions - at low energy consumption.
Speeds up to 2 m/s. Millimetre precise arrival. Automatic levelling of differences of level which may arise when loading or unloading the car.
Gearless drive assemblies
An engine without gears. The traction sheave is connected to the rotor of the electric motor with positive and friction locking.
Exceeds even the most elevated expectations regarding travelling comfort, swift and accurate docking – on all loading conditions - at low energy consumption.
Speeds up to 12.5 m/s.
Millimetre precise arrival. Automatic levelling of differences of level which may arise when loading or unloading the car.
Front Wheel Worm Gear
See above, worm gear
Exceeds even the most elevated expectations regarding travelling comfort, swift and accurate docking - on all loading conditions - at low energy consumption.
