Coffing Electric Chain Hoist

Coffing electric chain hoists are high performance hoists engineered
for heavy duty industrial service. Designed for safety, Coffing incorporates mechanical load brake, motor brake, and overload clutch as standard.

  • Rated loads from 1/4 to 5 Tons
  • 10, 15, and 20-foot standard lifts
  • 115/230, 208 - single phase; 230/460, 208, 220/380, 575 - three phase. 60 hertz standard, 50 hertz available. Two-speed motors available (3 to 1 speed ratio).
  • Features load bearing housings of ductile iron construction for maximum strength. Non-load bearing housings of cast aluminum alloy for minimum weight. Engineered and designed for use with higher torque 2 and 3 HP three phase motors.
  • Features housings of cast aluminum alloy construction for minimum weight. Engineered and designed for use with motors up to 1 HP.
  • Rigid or swivel top hook, lug, plain, geared, and motorized trolley available.
  • Built in compliance with ASME/ANSI B30.16 and CSA standards.

Coffing Brochure and Specifications

 

Coffing Electric Chain Hoists

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.
