New variable speed motor ! Electric chain hoist specially dedicated to « theatre application ».
Built-in inverter for hoisting motion. Extreme accurate (0,25 m/mn), smooth stepless and high lifting speed (16 m/mn). Price : You will be surprised !

The new generation SM10 hoists with variable speed is based on the proven inverter technology as being used for our industrial rope hoists.
The concept includes a built in 3 phase inverter with full scale braking resistor, filter, encoder for over speed control, limit switches and main contactor.

Due to the advanced inverter control technology, variation of speed could easily be achieved for single hoists using a push button station or group of hoists through the usual operation methods using up/down switches, a speedselector (fader) and a RUN button. There is no software involved or required to perform an operation. This makes the system cost effective and accessible for any standard rigging application.

The 2 pole motor is designed for 100Hz at nominal rpm, which doubles the speed range and thus results in an better and more sensitive variation in the low speed area compaired to 50Hz. motors.
