Winches PACCAR

PA90, PA110B, PA140 and H200 ● Hydraulically driven winch for infinitely variable con- trol of line speed and line pull including positive inch- ing control at maximum rated line pull. ● Optimized “high power” hydraulic control system including specialized directional control valve for maximum winching power and flexibility. ● Dual braking system provides a static brake with sprag clutch to eliminate fall-back and a hydraulic brake valve for dynamic braking. ● Single lever joystick control for ease of operation. ● Fabricated steel winch case with integral heavy duty drawbar provides excellent durability and easy weld- ability. ● Standard three-roller fairlead for improved wire rope life during side pulls. H60, H110B and H140 ● Hydraulically driven winch for infinitely variable con- trol of line speed and line pull including positive inch- ing control at maximum rated line pull. ● Standard Cat ripper control system is employed for winch “power-in” and “power-out” functions. ● Winch installation time is reduced by up to 70% com- pared to “high power” installations. ● Easy field interchangeability between winch and ripper. ● Dual braking system provides a static brake with sprag clutch to eliminate fall-back and a hydraulic brake valve for dynamic braking. ● Durable cast (H60) or fabricated steel (H110B and H140) winch case with integral heavy duty drawbar. ● Three-roller fairlead for improved wire rope life dur- ing side pulls is standard on H110B and H140 and optional on H60. ● “Free spool” to allow cable to be pulled off the winch by hand is standard on H60.

PACCAR Features: PACCAR winches have been installed on Cat trac- tors since 1932. After acquiring the intellectual and property rights of Cat tail winches in the early 1990’s, PACCAR Winch has exclusively supplied Caterpillar manufacturing facilities worldwide with tractor winches for factory installation. PA40 and PA50 ● Closed loop hydrostatic operation with variable displace- ment motor and dedicated variable displacement pump for maximum winching power and flexibility. ● Infinitely variable control of line speed and line pull including positive inching control at maximum rated line pull. ● Standard full - function “power-in” and “power-out” control . This is optional on some competitive winches. ● Standard “drive-away” to maintain tension on the cable when driving the tractor away from a stationary load. ● Standard “free spool” to allow cable to be pulled off the winch by hand. ● Durable cast winch case with fairlead mounting lugs, log arch mounting lugs, and heavy duty drawbar. PA55, PA56 and PA80 ● PTO mechanical winch drive with full tractor engine power available to the winch. ● Self-contained internal hydraulic control system for easy installation. ● Equal speed gearing in “reel-in” and “reel-out” to provide smooth and predictable performance. ● Standard “drive-away” to maintain tension on the cable when driving the tractor away from a stationary load. ● Standard “free spool” to allow cable to be pulled off the winch by hand. ● Durable cast winch case with fairlead mounting lugs, log arch mounting lugs, and heavy duty drawbar.
