Frequency inverting electric hoist controls rotation speed of motor by changing the power frequency with transducer, which has following features:
1. Reduce impact during start and stop, thanks to its stable operation, this electric hoist can reduce impact during start and stop, and is especially suitable to some precision jobs such as mould installation etc. where vibration is a big trouble.
2. Adjustable working speed, it has speed choices between 10% to 100% rated speed, you can select your most proper operation speed according to your actual requirements.
3. Speed up to improve working efficiency, you can adjust speed up to 150% of its rated speed during idle operations.
4. Set up running speed of the Crab/trolley conveniently
It can conduct frequency inverting control over the running motor with inverter making motor capable to run with slight speed, thus improving the accuracy of positioning or jogging operations.
