Frequency converting Electric Hoist

الوصف

Frequency converting electric hoist controls rotation speed of the motor by changing the power frequency with transducer, which has following features:
1, Reduces impact during start and stop, for its stable operation, this electric hoist can reduce impact during start and stop, and is especially applicable for none  vibration allowed on precision mould installation field.
2, Speed can be set to your want.
From *0% to **0% rated speed according to the requirement to choose the most proper operation speed.
3,Inproves working efficiency
It can set the lifting speed between rated speed and 1.5 times of that when in the idle operation in order to improve the working efficiency.
4,Set up running speed of the trolley conveniently
It can be carry out frequency converting control over the running motor with frequency converter and make the motor run under slight speed, thus improving the accuracy of operation in addition to the jogging operation.
