High Speed Vf Hoist - 100 M/min Max Lifting Speed | Advanced Vf Speed Control, Stepless Speed Control, Automated Leveling, Energy Efficient Protection Systems

To serve the increasing demand for high-rise construction, we developed the high speed VF hoist, with a max, lifting speed of 100 m/min.

Salient Features of High Speed Construction Hoist :-
A.Adopts the most advanced VF speed control device and microcomputer programmable logic controller.

A.Stepless speed control helps eliminate the concussion during start up and braking, steady the operation process, and ensures automated leveling.

A.Adopts open loop V/F control; the sp. control precision can reach A 2i 3%. Realizes accurate low speed positioning of the hoist and avoids slipping during downward stopping of hoist.

A.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 energy consumption and mitigates effects to on site electric equipments.

A.The steadiness during running mitigates concussion to mechanical parts, reduces wears of rack, pinion and the brake and prolongs the spare partsa life.

A.The VF system also has the over voltage protection, low-voltage protection, over current, overload and anti-stalling protection functions.
