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.

Notes:

1. Maintain a minimum of 3 tight wraps of wire rope on the

drum at all times.

2. Ensure the wire rope does not exceed top layer

requirements. Refer to “SPECIFICATIONS” section.

3. Maintain a minimum of 1.6 feet (0.5 m) per inch of drum

length. Example: for a 7 inch drum length, locate the lead

sheave at least 11.2 feet (3.51 m) from drum.

CAUTION

• Maintain at least 3 wraps of wire rope on the drum at all

times. Refer to Dwg. MHP0498.

Wire Rope Selection

Consult a reputable wire rope manufacturer or distributor for

assistance in selecting the appropriate type and size of wire rope

and, where necessary, a protective coating. Use a wire rope

which provides an adequate safety factor to handle the actual

working load and meets all applicable industry, trade

association, federal, state and local regulations.

When considering wire rope requirements the actual working

load must include not only the static or dead load but also loads

resulting from acceleration, retardation and shock load.

Consideration must also be given to the size of the winch wire

rope drum, sheaves and method of reeving. Maximum wire rope

diameter is limited by the wire rope anchor. Wire rope

construction should be 6 x 37 Extra Improved IWRC right lay to

permit correct installation of wire rope. Refer to Table 1 for

minimum and maximum recommended wire rope diameters.

Installing Wire Rope

1. Cut wire rope to length in accordance with the wire rope

manufacturer's instructions.

2. Feed the end of the wire rope into the smaller anchor hole

in the wire rope drum and pull through approximately one

foot (0.3 m) of wire rope.

3. Tuck the end of the wire rope back into the wire rope

anchor pocket forming
