The CM Prostar electric chain hoist is built for unique rigging applications encountered at small venues. With a compact design that is lightweight, quiet, and portable, it features an overload device that protects the hoist, operator, and structure from damaging overloads. Simultaneous brake activation delivers two times the brake torque in the hoist when compared to aftermarket brakes. An electromagnetic spring applies the double DC brake distributing nominal brake torque of 40.32 cm/Kg (4 Nm) per brake. The non-adjusting DC electromechanical brake ensures quiet operation and low maintenance. The hoist has a rated capacity of 136kg to 500kg with standard lift of 18m. Operating at speeds ranging from 2.4m/m to 12.19m/m, the device is H-4 duty rated and designed for heavy-duty application. Additional features include heat-treated precision machined gears; one piece, jam free, chain guide; CM-patented 10-pocket oblique lift wheel; and a chain stop mounted on the load chain. The load chain is zinc-plated to protect against corrosion. The cast aluminum housing is available in a black powder coated finish. Single-phase and three-phase models are available.
