1.1
Installing the Winch
Do not install the winch in an area defi ned as hazardous by the National Elec-
tric Code, unless installation in such an area has been thoroughly ap proved.
Do not install the winch near corrosive chemicals, fl ammable materials, ex-
plo sives, or other elements that may damage the winch or injure the op er a tor.
Ad e quate ly protect the winch and the operator from such elements.
Position the winch so the operator can stand clear of the load, and out of the
path of a broken wire rope that could snap back and cause injury.
Attach the winch to a rigid and level foundation that will support the winch
and its load under all load conditions, including shock loading.
Install the wire rope securely to the winch drum. A poorly secured wire rope
could come loose from its anchor and could release the load. See fi gure 3 & 4.
1.1.1
CONSULT APPLICABLE CODES AND REGULATIONS for specifi c rules
on installing the equipment.
1.1.2
LOCATE THE WINCH in an area clear of traffi c and obstacles that could inter-
fere with operation. Make sure winch is accessible for maintenance and operation.
1.1.3
MAINTAIN A FLEET ANGLE between 1/2 and 1-1/2 degrees. The proper
fl eet angle minimizes wire rope damage by helping the wire rope wind uni-
form ly onto the drum. See fi gure 1.
1.1.4
FASTEN THE WINCH securely to the foundation.
a
FOR STANDARD PRODUCTS referred to in this manual, use 3/8 inch
coarse thread fasteners, grade 5 or better. Torque for grade 5 fasteners with-
out lubrication is 30 ft. lb. Make sure mounting holes are secured to a solid
foundation able to support the winch and the load under all conditions with
design factors based on accepted engineering practices. For mounting rec-
ommendations, see fi gure 2.
b
NON-STANDARD PRODUCTS that vary from the original design may
have different fastening requirements. Contact a structural engineer or Th-
ern, Inc. for this information.
TO COMPLY WITH LOCAL CODES, CONTACT A QUAL I FIED

Important!
• Inspect the winch immediately
following installation according
to the Instructions for Periodic
Inspection. This will give you
a record of the condition of the
winch with which to compare
future inspections.
• A qualifi ed professional should
inspect or design the founda-
tion to insure that it will provide
adequate support.
• Locate the winch so it will be vis-
ible during the entire op er a tion.
• Do not weld the winch frame to
the foundation or support struc-
ture. Welding the frame may void
warranty, contact Thern, Inc. Use
fasteners as instructed.
