HAYASHIMU Traction Machine, JAPAN
Geared traction elevators are unique with their simple structure and mature technology and are an excellent fit for freight and low-speed elevators. A typically geared traction elevator is usually propelled by an AC or DC electric motor. They also have gears between their electric motor and sheave, which drives the pulley and moves the steel ropes or flat steel belts.
80% of the traction elevators on the market are gearless, making them the most widely used. If you have a mid to high-rise building, then you don’t need to think twice about installing the gearless model because they can operate at very high speeds. Unlike the geared model, gearless elevators have their electric motor directly connected to the sheave.
The gearless model is usually driven by a synchronous motor and has a simple structure, reliable operation, small size, lightweight, high efficiency, low speed and high torque. Depending on the elevator model, configuration, and application, it can also reach between 2,000 to 4,000 ft./min.
Even so, if you want your elevator to move at a far slower speed like a typical hydraulic elevator, you need not worry because we can help you design a gearless elevator that moves at the rate of 100 ft./min.
A gearless elevator has high initial investment and moderate maintenance costs and is more energy efficient than the geared model. Therefore, they may be excellent for your tall and ultra-high buildings if you prioritize speed and energy efficiency.
