Taking the lead in adopting the permanent magnet synchronous variable frequency traction machine in the escalator
Escalator adopting planetary gear train drive for the first time
The first lot of escalators with independently researched permanent magnet synchronous motor and planetary speed reducer integration drive
The first lot of escalator with feedback intelligent braking system
The traction machine directly drives the main drive shaft and the traction machine drive chain is not required, which will significantly lower the transmission noise and eliminate the inherent shaking and vibration of the chain; meanwhile the usage of the lubricating oil on the escalator will be reduced greatly which will reduce the oil pollution.
New intelligent brake control system –the intelligent braking system of the feedback device, the braking force will be changed according to the load and velocity load to make the escalator more safe and reliable.
