Lifting Hoist 10ton European style low headroom wire rope electric hoist

タイトルまたは説明

Working class is M4~M7, and pulley group multiplying power is 2/1,4/1,4/2,6/1,8/1 and 8/2 etc.

Installation of electric hoist is classified into low building height single*-track trolley type ( D model, applied single track and single-girder cranes), double*-track trolley type (S model, applied to double*-girder cranes), and fixed type ( G model). Traveling speed is 2~*0m/min with stepless frequency conversion, and standard lifting speed 5/0.8m/min. Also frequency conversion is adopted to make the electric hoists steady lifting and braking, as well as lifted weights small swing. Precise positioning gets operation greatly improved.
