1.4 Install the Rope
WARNING
ALWAYS complete the winch installation and hook attachment before hooking up the
hydraulic pump.
ALWAYS pre-stretch rope and re-spool under load before use. Tightly wound rope reduces
chances of "binding", which can damage the rope.
A minimum of five (5) wraps of steel wire rope around the drum is necessary to support the
rated load.
ALWAYS spool the winch rope onto the drum in the direction specified by the drum rotation
labels on the winch and/or in the documentation. This is required for the automatic brake to
function properly.
Roller fairlead
The use of 4 ways roller fairlead can eliminate the contacting friction because the fairlead rollers
contact with the wire rope. But the fairlead does not insure the wire rope will wind onto the drum in an
orderly manner. The proper fleet angle within ±5° must be maintained for the wire rope to wind onto
the drum in an orderly manner. If the proper fleet angle is not maintained, it can result in damage to the
winch and wire rope.
Cable Tensioner
The purpose of cable tensioner device is to keep the wire rope
tight on the drum while the winch is in free spool mode or while
there is no load on the wire rope.
