Can be operated on 50 Hz of power with only 16% reduction in lifting speed. DC electromagnetic brake holds the load even if power is interrupted. Pre-wired at 230V—single-phase models can be switched on-site to 115V; three-phase units can be switched to 460V. Also includes: heavy-duty chain container, quick-connect wiring for power and pushbutton controls, and upper and lower limit switches. Totally enclosed steel plate construction and durable powder coat finish.
