Equipment Features for Coffing Model EC Electric Chain Hoist


Coffing Electric Chain Hoist Model EC


HOIST TYPE:  COFFING HOISTS
Model EC Electric Chain Hoist is a High Performance Hoist that is engineered for heavy duty industrial service.

Designed for safety, this Model EC does have a Weston – style load brake in addition to the Motor Brake.  Compliant with ASME/ANSI B30.16 and CSA standards.

Includes Coffing Lifetime warranty.



Coffing Hoist Suspension Parts

Coffing Hoists Suspension Parts


HOIST SUSPENSIONS:
  Hoists may be may be suspended by these methods

  • Hook

  • Push Trolley

  • Motorized Trolley (Single Speed or Two Speed)

Available from 1/4 through 5 Ton capacity. 

Lift heights are standard at 10’, 15’, or 20’.  Longer lifts are readily available when needed.



Coffing Hoist Motor Brake


MULTIPLE DISC MOTOR BRAKE: 
Heavy Duty, direct acting design for positive load spotting and holding.


Coffing EC Hoist Gears and Transmission


GEARING and TRANSMISSION: 
Transmission gears are precision machined of alloy steel and run in an oil bath for a longer and quieter operation.

SMALL FRAME DESIGN - First stage helical gearing on small frame hoists.   Features housings of cast aluminum alloy for minimum weight for under 2 H.P. motors.

LARGE FRAME DESIGN -First and third stage helical gearing on large frame hoists.  Features load bearing housings of ductile iron construction for maximum strength…for higher torque 2 and 3 H.P. motors.  Non-load bearing housings are of cast aluminum for minimum weight



Coffing EC Hoists Overload Clutch


OVERLOAD CLUTCH:
 This protects the hoist, operator, and supporting structures from damaging overloads, chain jamming, and reverse phasing


Coffing Hoist Mechanical Load Brake


MECHANICAL LOAD BRAKE:
 Model EC.  Weston Type Load Brake controls load lowering speed and prevents load drift.  Holds rated load independent of the multiple disc motor brake.


Coffing Hoist Load Sheave


LOAD SHEAVE:
  Load Sheave is a Five-Pocket design.  This increases chain and sheave engagement by 25% over hoists with conventional four-pocket sheaves.  Provides smoother lifting and reduces chain wear over four-pocket sheaves.


Coffing EC Hoist Steel Chain


STEEL CHAIN: 
Is precision pitch, treated for optimum strength and wear resistance.


Coffing Hoist Control Panel


HOIST CONTROL 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 or repair.



Coffing Hoist Limit Switches


LIMIT SWITCHES: 
Adjustable to regulate upper and lower load travel.  Brass nuts standard for improved switch setting and repeatability.

Stainless steel limit switch shaft is standard.



Coffing Hoist Pendant Push Button Hand Control


ERGONOMIC PUSH – BUTTON PENDANT: 
Fits operator’s hand for thumb or two-handed operation.

Constructed of glass-filled nylon for severe impact and chemical/corrosive atmosphere resistance.  NEMA 3R (Weather Resistant)

Standard Pendant is 4’ less than the lift.

Standard control voltage is 24V.



Coffing Hoists Load Hooks


LOAD HOOKS: 
Are forged carbon steel and under excessive loads, will open gradually and not fracture.

Ball bearings produce smooth rotation.  The hook will swivel 360 degrees.  Heavy - duty hook latches are standard.



Coffing Chain Hoist - Chain End Stop Assembly


CHAIN END STOP ASSEMBLY: 
Fits below dead end link on lifting chain for an added measure of safety.


Coffing Chain Hoist Starting Switch


SOLID STATE STARTING SWITCH:
This is standard on single phase units. Provides greater reliability and starting consistency than centrifugal switches – fewer components to wear out or fail.


Coffing Single Phase and Three Phase Chain Hoists


VOLTAGES: 
Single Phase and Three Phase Models are available.  Not all Models are available in Single Phase.

  • Single Phase:  115/1/60, 230/1/60

  • Three Phase:  208/3/60, 230/3/60, 460/3/60




AVAILABLE ITEMS:

  • Chain Containers are Recommended

  • Two Speed Lifts (3:1 Speed Ratio)

  • Two Speed Motorized Trolleys (3:1 Speed Ratio)
