The JET® SSC Series 1SS-1C-20 Electric Chain Hoist with 1-Phase 20' Lift (JT9-112000) combines safety and durability to operate in commercial and industrial applications. This electric hoist incorporates a slip clutch overload protection mechanism that prevents the hoist from lifting damaging loads above its rated capacity. This single phase model has a thermal overload protection design that keeps the hoist from overheating, while the three phase models feature a reverse phase relay that protects the hoist from incorrect wiring. The industry proven DC electro-magnetic brake increases safety by holding the load even when power is interrupted. The maintenance-free gear train incorporates a sealed oil bath, for reliability and durability.
