l Product specification
Size up to 800-1500 m² wind resistance: 12grade
2 sets of hydraulic push rod brake and 1 set of height limitation device are built in the hoist mechanism, the upper and lower limit switch are used for guarantee no over run of the door
Eddy current AC motor combine with cylinder type gear box, drive the parallel hoist winding drum where steel cable is used to lift up the door curtain.
On the shaft between the motor and the gear box and the output shaft of the gear box, two hydraulic push rod brake system are applied individually. The running speed of the door is adjusted by the eddy current of the motor; the end limit switch in the hoist drum limits the highest and lowest position of the door.
Safety brake system will lock the door in case the steel cable is broken during the door is running.
Door dimension range: height, 5-40 m
Total weight: 0.5-20 ton
