Manual Winches De Levantamiento

Prior to installing the winch, carefully inspect it for possible

shipping damage.

Winches are supplied fully lubricated from the factory.

CAUTION

• Owners and users are advised to examine specific, local or

other regulations, including American National Standards

Institute and/or OSHA Regulations which may apply to a

particular type of use of this product before installing or

putting winch to use.

Mounting

1. Do not weld to any part of the winch.

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 end covers

and spacers resulting in winch damage.

3. Make sure the mounting surface is flat to within 1/32 inch

(0.8 mm). Shim if necessary.

4. Mounting bolts must be 3/8 in. (10 mm) diameter, Grade 8

or better. Use self-locking nuts or nuts with lockwashers.

5. Tighten mounting bolts evenly and torque to 50 ft. lbs. (68

Nm) for dry thread fasteners. If the fasteners are plated,

lubricated or a thread locking compound is used, torque to

35 ft. lbs. (47 Nm).

6. When a lead sheave is used, it must be aligned with the

center of the drum. The diameter of the lead sheave must be

at least 18 times the diameter of the wire rope.

7. Maintain a fleet angle between the lead sheave and winch

of no more than 1-1/2 degrees. The lead sheave must be on

a center line with the drum and, for every inch (25 mm) of

drum length, be a least 1.6 feet (0.5 m) from the drum.

Refer to Dwg. MHP0498.
