WARN Industrial Winches
What is a Winch?
WARN Industries produces a large family of
winches and hoists. But what makes a winch
different than a hoist?
Winches and hoists look alike. Both consist of a
motor, a rotating drum with rope, reduction gears,
a base, and usually an electrical control system.
However, winches and hoists are used for
different purposes.
Winches are used to pull a load horizontally
across the ground, while hoists are used to lift a
load into the air. Unlike hoists, the operator of a
winch may unwind cable by “free spooling” or
disengaging the motor from the gear train using
the built-in clutch. Then the operator reverses the
position of the clutch to connect the motor to the
gears and pull the load.
Pre-Install Checklist
1 Check to see that you have received the
following:
• The winch
• The winch mounting hardware
2 Upon removing winch from packaging, check
for damage including bent or cracked tie rods,
tie bars, or housings. Correct any damage
before installing winch.
3 Make sure the environment surrounding
winch and controller is free of :
• Combustible vapors
• Chemical fumes
• Oil vapors
• Corrosive material
4 Make sure that the air temperature
surrounding the winch and controller stays
within 120° F (49° C) and -20° F (-29° C).
5 Make sure that the mounting structure can
withstand the full rated pull of the winch.
Mounting the Winch
Mounting Bolts:
Use the supplied fasteners whenever possible or
SAE Grade 8 bolts of the same thread size. The
tie plates, tensioner bracket, and spacers
supplied with the winch should NOT be removed.
Mounting brackets (if required) should be added
to the tie plates and spacers supplied with the
winch. Mounting brackets thicker than ½ inch
(12mm) in thickness may require longer mounting
bolts to be used. The bolt threads must extend a
minimum of ¾ inch (19mm) into the drum
supports. Bolts that are too long or too short will
fail to anchor the winch securely and may cause
a failure of the winch mounting.
Mounting Brackets:
When foot mounting the winch, the mounting
plate should be a minimum of ½ inch thick steel.
A thinner mounting plate will not support the
winch properly and may cause a failure of the
winch mounting. Foot mounting plates thicker
than 1/2 inch (12mm) will require longer mounting
bolts.
When side mounting the winch, brackets must be
a minimum of 4 inch (100mm) by 4 inch (100mm)
by ½ inch (12mm) thick angle iron or larger.
Mounting brackets with inadequate thickness
may cause a failure of the winch mounting. Side
mounting brackets thicker than 1/2 inch (12mm)
will require longer mounting bolts.
1 Make sure that the mounting surface is flat
within +/-0.020 in. (0.50 mm). If the surface is
not flat, use shim stock as needed to avoid
straining the winch.
2 Torque all mounting bolts to the
recommended values on the product data
sheet.
3 Use the mounting hole locations provided on
the product data sheet.
