Wittur WSG-TB Belt Gearless Elevator Traction Machine
Wittur WSG-TB is a technical elevator traction machine designed for compact MRL belt systems and low-rise modernization. It offers efficient gearless drive performance, smooth ride quality and reliable integration with modern lift control systems.
Description
What is a belt-driven gearless machine?
The Wittur WSG-TB is a belt-driven gearless elevator traction machine. Instead of steel wire ropes it uses flat coated-steel or polyurethane belts, which allow a much smaller sheave diameter and therefore a more compact machine.
Belt-driven machines are used in machine roomless (MRL) elevators and home lifts where shaft space is tight and a low-profile drive unit is required. Nazar Elevator supplies the Wittur WSG-TB to elevator contractors and distributors worldwide.
