3.0 GENERAL DESCRIPTION
The GMP SideWinder is a trailer mounted pull and assist capstan winch,
mounted on a sturdy all-steel fabricated chassis. It is equipped with torsional
suspension axles, stabilizing prop legs, a front telescopic jockey wheel and a
tow bar with a Lunette Ring. The unit is easily pulled by a standard pickup
truck.
The power source is a gasoline engine which drives the fixed displacement
tandem mounted hydraulic pumps. The hydraulic pump is attached to the en-
gine via a bell housing and flexible coupling. One pump powers a hydraulic
motor, through an in-line planetary gearbox, to the capstan. The second pump
drives the rope take-up drum again through a hydraulic motor.
The hydraulic oil tank is fitted with double filtration protection, sight glass and
filler/breather.
Controls are operator friendly and very simple to use. A spring centered lever
controls the direction of rotation of the capstan, while a detented lever engag-
es the take-up drum drive. A control knob is used to limit the rope/cable ten-
sion using the panel mounted tension indicator.
The rope take-up drum is removable and can be split to enable removal of
rope. The capstan can be rotated through 90° on a swivel bracket from the in-
line working position to the transverse transit position when in tow.
When the winch is in the working mode the rear props are extended out of the
chassis to provide greater stability.
