3. Allow the end of the wire rope (1) to extend about 2 in. (50
mm) through the center hole (5). Pull the smaller loop (6)
tight.
4. Pull large loop (7) tight so it presses the wire rope end (1)
against the drum flange.
Installing Wire Rope (15,000 lb. - 25,000 lb. winches)
1.
Cut wire rope to length and fuse end to prevent fraying of
strands in accordance with the wire rope manufacturer's
instructions.
2. Feed the fused end of the wire rope into the wire rope
anchor hole. Position the end of the wire rope just beneath
the drum surface. Refer to Dwg. MHP0218.
(Dwg. MHP0218)
3. Make sure the wire rope wedge is the correct size for the
wire rope.
4. Install the wire rope wedge into anchor hole. Install the
wedge from the side of the hole with the wire rope end.
Position the wedge so the serrated surface is on the wire
rope. Insert the narrow end of the wedge first. The wedge
must be positioned so it is nearer the surface of the drum.
5. Hammer the wedge into the wire rope anchor hole to secure
the wire rope.
6. While keeping the wire rope under tension, wind the wire
rope onto the drum.
CAUTION
• Make sure the first wrap of wire rope is flush against the
drum flange.
Wire Rope Spooling
To allow for uneven spooling and decrease in line pull capacity
as the drum fills up, use as short a wire rope as practical. To
rewind wire rope apply tension to eliminate slack. This helps
achieve level winding and tight spooling
Rigging
Make sure all wire rope blocks, tackle and fasteners have
sufficient safety margin to handle the required load. Do not
allow wire rope to contact sharp edges or make sharp bends
which will cause damage to wire rope, use a sheave. Refer to
wire rope manufacturer's handbook for proper sizing, use and
care of wire rope. Refer to instruction 5 under “MOUNTING”
for allowable wire rope fleet angle.
Safe Wire Rope Handling Procedures
1.
Always use gloves when handling wire rope.
2. Never use wire rope which is twisted, frayed or kinked.
3. Never use wire rope as a sling.
4. Always ensure wire rope is correctly spooled and first layer
is tight against the drum.
Torque Limiter (optional feature)
Ensure torque limiter is adjusted for required application. Refer
to “MAINTENANCE” section for adjustment procedure.
Wiring
Be sure phase, cycle and voltage of motor, magnetic reversing
starter and controls all match the electrical service being used.
Check power supply is correctly grounded. All electrical
connections must be properly insulated and enclosed.
WARNING
• Never use a motor with a voltage power supply other than
specified. The motor can be permanently damaged.
• Switches and starter enclosures must be grounded to
electrical supply system.
Power supply voltage must be within 5%.

Refer to “Recommended Copper Wire and Transformer Size”
chart on page 49 for assistance in selecting the correct electrical
wire size.
Brake Connections
Brake power connections depend on winch power voltage and
brake operating voltage. Drawings MHP0247, MHP0248 and
MHP0249 show the three possible combinations for 230/460V
motors. Drawing MHP0307 shows brake connections for 380V
and 575V motors. Refer to drawings MHP1087 and MHP1088
for location of brake power connection lines.
