General Machine Products 70524 Adams CD3 Continuous Duty Winch - Manual (Page 11)

AK 7/18/2012 ver 5
The pressure from either side of the motor can release the brake. This feature enables the winch to pull in as well
as power out. The brake is not direction sensitive.
The maximum pressure rating is 3000-psi including spikes or surges.
WARNING - SURGE PRESSURE IN EXCESS OF 3000 PSI GENERATED BY PUMP SURGE OR
RAPID OPENING OR CLOSING OF THE CONTROL VALVE WILL CAUSE THE PISTON TO
FRACTURE.
The O-rings (Buna "N" material) in the piston are only compatible with petroleum-based fluid. DO NOT USE
NON-PETROLEUM BASED FLUID.
The brake is provided with a case drain. Should fluid leak into the brake housing, the case drain will open to let
the fluid escape. If fluid leaks from the case drain, contact the factory for assistance.
WARNING - THE FULL LOAD BRAKE MAY NOT HOLD THE RATED LOAD IF THE CASE
DRAIN IS LEAKING FLUID.
Any backpressure in the tank return line may reduce the holding power of the brake. The brake is spring applied
and hydraulically released. The backpressure may start to release the brake, thus reducing the holding power of the
brake.
CAUTION - BENCH TESTING IS NOT RECOMMENDED BECAUSE IT MAY CAUSE DISTOR-
TION OF COMPONENTS OR BOLT FAILURE.
3.06 WIRE ROPE INSTALLATION – When installing the wire rope, observe the following recommenda-
tions:
It is important to select the correct winch and wire rope for a particular application. Wire rope is specified in terms
of diameter, length, number of strands, number of wires per strand, composition of center core and direction of lay.
There is a definite advantage in applying wire rope of the proper direction of lay when spooling onto the smooth
surface of the winch drum. Wire rope with an improper lay will permit the coils to spread apart each time the load
is removed. Using wire rope with the proper lay will tend to keep the coils together when tension is removed. The
correct lay will develop tight coils and even layers.
It is important to install the wire rope onto the winch drum with care. Kinking of the rope, caused by the rope tak-
ing a spiral shape as a result of an unnatural twist, should be avoided.
When removing wire rope from the reel and spooling onto the winch drum, the reel must be supported on its hori-
zontal axis and free to rotate. Spool the rope onto the drum with the natural bend in the same direction as it comes
off the reel.
If wire rope is received in a coil, it should be unwound with the coil in the vertical plane. Again, spool the rope
onto the winch drum with the natural bend in the same direction as it was on the coil. Reverse bending of the wire
rope should always be avoided or kept to a minimum.
IMPORTANT! WIRE ROPE MUST ALWAYS BE UNDER CONSTANT TENSION WHEN
SPOOLING ONTO THE WINCH DRUM.
When the winch drum is in free spool and only the drum shaft extension is being used with a capstan or reel, pass
the winch line through the tail shelf sheave and hook the pulling eye to a fixed section of the chassis. This will
prevent the rope from unwinding or "clock-springing."
