●Helical Gear Traction Machine

The helical gear is made of high-grade alloy steel by high precision manufacturing technology.  It is thoroughly heat-treated and processed.  It can achieve low-noisy、stable、smooth and high efficiency transmission, thus the best gear for the elevator.

Our technical achievement with the design and production of the big heavy-duty Helical Gear Machine. 

l  Precise design & High efficiency

Due to precise design and manufacture by modern computer technique machine.  It can reach 95% of efficiency and save energy.

l  Small machine and 20-35% weight less then worm gear machine.  It suitable for machine room or machine roomless elevator to use.

l  Steady temperature rising and low-noisy.

l  Reliable with variable design.
