SideWinder 42 inch Capstan manual

The GMP SideWinder Trailer-Mounted Fiber Optic Puller SideWinder Fiber Optic Pullerhas been designed to exceed the requirements of installing underground telecommunication cables, high-density fiber by employing a 42 in. diameter single capstan to provide a controlled force to the pulling rope or tape.

The single capstan allows the winch to be placed at the midpoint of a section to assist in the pull, thus enabling longer pulls to be achieved.

42 Inch Capstan SideWinder Pull and Assist Capstan Winch
  • The Sidewinder’s capstan is angled at 30° to be used to figure 8 the cable
  • 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 engages the take-drum drive. A control knob is used to limit the rope/cable tension using the panel-mounted tension indicator.
  • The winch is 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
  • At 1500 lbs., the unit is easily pulled by a standard pickup truck
  • The power source is a Commercial grade Honda GX390 gasoline engine
  • The engine drives the fixed displacement tandem-mounted hydraulic pumps. One pump powers a hydraulic motor through an in-line planetary gearbox to the capstan; while the second pump drives the rope take-up drum through a hydraulic motor. The hydraulic pump is attached to the engine via a bell housing and flexible coupling.
  • The hydraulic oil tank is fitted with double filtration protection, sight glass, and filler/breather
  • The rope take-up drum is removable and can be split to enable the removal of the rope. The capstan can be rotated through 90° on a swivel bracket from the inline working position to the transverse transit position when in tow. When the winch is in working mode, the rear props are extended out of the chassis to provide greater stability.

SideWinder as a power source for the Tornado Blowing Machine:Using accessory part number 32482, the SideWinder has the capability of powering the hydraulic system of the Tornado Blowing Machine thereby eliminating the need to have a separate power pack. Do to the higher rating of the Sidewinder's hydraulic system, the pushing force of the Tornado will be equal to the power pack but the speed will be increased up to 2 1/2 times. This can be regulated via the speed control on the Tornado.
