The Following are Standard Features Included on Every EC Chain Hoist
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.
Mechanical Load Brake
Weston type, controls load lowering and prevents load drift. Holds rated load independent of multiple disc motor brake.
Panel Plate
Provides easy access to controls and motor leads for changing voltages on dual-voltage motors or performing hoist maintenance. Connection wires are numbered to assist maintenance.
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.
Multiple Disc Motor Brake
Heavy duty, direct acting design for positive load spotting and holding.
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.
Mechanical Overload Protection
Protects hoist, operator, and supporting structures from damaging overloads, chain jamming, and reverse phasing.
Ergonomic 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). Severe impact and chemical/corrosive atmosphere resistant.
Chain End Stop Assembly
Fits below dead end link on lifting chain for an added measure of safety.
