High Performance and Safety
Coffing EC Hook & Lug Suspension Models are high performance hoists engineered for heavy duty industrial service. Designed for safety, the EC incorporates mechanical load brake, motor brake, and overload clutch as standard.
Mechanical Load Brake
Weston type, controls load lowering and prevents load drift. Holds rated load independent of multiple disc motor brake
Multiple Disc Motor Brake
Heavy duty, direct acting design for positive load spotting and holding.
Ergonomic Designed Push Button Station
Fits operator’s hand for thumb or two-handed operation. 24 Volt Control standard for operator safety. 115 Volt Control available upon request. NEMA 3R (weather resistant). Constructed of glass-filled nylon for severe impact and chemical/corrosive atmosphere resistance.
Five-Pocket Load Sheave
Increases chain and sheave engagement 25% over hoists with conventional four-pocket sheaves. Provides smoother lifting and reduces chain wear over four-pocket sheaves.
Limit Switches
Adjustable to regulate upper and lower load travel. Brass nuts standard for improved switch setting and repeatability. Stainless steel limit switch shaft standard.
Solid State Starting Switch
Standard on single phase units. Provides greater reliability and starting consistency than centrifugal switches. Fewer components to wear out or fail.
Panel Plate
Provides easy access to controls and motor leads for changing voltage on dual-voltage motors or performing hoist maintenance. Connection wires are numbered to assist maintenance.
Chain End Stop Assembly
Fits below dead end link on lifting chain for added measure of safety.
Gearing & Transmission
First stage helical gearing on EC small frame; first and third stage helical gearing on EC large frame. Transmission gears are precision machined of alloy steel and run in oil bath for longer, quieter operation.
Overload Clutch
Protects hoist, operator and supporting structures from damaging overloads, chain jamming, and reverse phasing.
