*Based on pressure of 2,500 psi (173 bar), 115 gpm (436 lpm), 1 1/4” (32 mm) rope and 12.03 CID motor.
Actual performance will vary dependent on hydraulic system, motor, drum and cable sizes.
**High Speed Reverse (HSR) reel out line speed is 4.7 times faster than reel in speed. The high-speed reelout function should only be used within the limits of the unit’s lifting capacity when controlling the load.
