Main Parts of Building Hoist 

● Adopts the most advanced VF speed control device and microcomputer programmable logic controller.

● Stepless speed control helps eliminate the concussion during start up and braking, steady the operation process,

and ensures automated leveling.

● Adopts open loop V/Fcontrol; the speed control precision can reach ±2~3%. Realizes accurate low speed positioning of the hoist and avoid slipping during downward stopping of hoist.

● The VF system has current-restriction function, ensuring a small current when motor start up and reducing the concussion to power supply. It reduces the engery consumption and mitigates effects to on site electric equipments.

● The steadiness during running mitigates concussion to mechanical parts, reduces wears of rack, pinion and the brake

and prolongs the spare parts'life.   

● The VF system also has the over voltage protection,low voltage protection, overcurrent, overload and anti-stalling     protection functions,

● The system applies the special software for hoists developed by our company, making the operation more safe and

Q:How to set up the construction elevator?
According to drawings, find the embedded at the scene near the level of architectural axis positioning and high elevation line (50 wire or 1 m wire) location and double-check, axis dividing levels as much as possible in accordance with the size distribution. Find out after each axis, measuring building contour, and map measure the buildings, and building construction drawing contrast, timely transfer measurement results to the designer, designer analyze the error and make changes
Q:Can construction elevators be taken by people or by goods
 yes, you can! It is to pass the authority authority to issue use card to be able to use! Construction lifts are also called elevators
Q:How does the elevator operate
