Mounting
Use the winch lifting lugs to move, position, or install the winch. Refer to

• Only use the lifting lugs on the winch for lifting or moving the winch.
• Do not weld to any part of the winch.
• Do not weld the winch to a structure. Make sure that the bolts are correct size and strength
to install the winch to the structure.
1. Make sure the winch is positioned to allow for proper spooling of the wire rope onto the drum. When installed
correctly, the direction of the drum for lift is clockwise as viewed from the motor end of the winch. Refer to
2. The winch mounting surface must be flat and of sufficient strength to handle the rated load, plus the weight of
the winch and attached equipment. An inadequate foundation may cause distortion or twisting of the winch
uprights (endframes) and base resulting in winch damage.
3. Make sure the mounting surface is flat to within 0.005 inch (0.127 mm) per inch of the drum length. Shim if
necessary.
4. Make sure that the winch is correctly grounded to the personal lifting system before using.
5. Use 5/8 inch (16 mm), class 8.8 or better mounting bolts. Tighten evenly and torque to 150 ft lbs (203 Nm) for dry
thread fasteners. If the fasteners are plated, lubricated or a thread locking compound is used, torque to 99 ft lbs
(134 Nm). Use self-locking nuts or nuts with lockwashers.
6. Refer to
for installation of wire rope and the Product Safety Information manual.
