Hydraulic Tri-Drive Three-Speed
Transmission (Model 230-1600)
• Rated working capacity: 20,000 lbs. bare drum pull
• Winch input torque: 4,750 in./lbs. max. at 600 RPM
• Winch input speed: 1,600 RPM max.
• Rated working capacity: 20,000 lbs. bare drum pull
• Hydraulic flow: 30 GPM maximum
• Hydraulic system pressure: 2,000 psi operating
2,100 psi maximum bypass relief
If actual operating pressure exceeds recommended maximum, in low con-
trol valve position, the winch will generate a pulling force beyond its rated
working capacity. Such a condition can damage the winch, cause wire rope
failure or result in injury to persons or property. It is most important that the
maximum operating pressure be restricted to permit a specifically limited
winch line pull.
• IMPORTANT NOTE: Winch line speed based on 9/16"
dia. wire rope for all drive types. 1

In low gear, this winch can generate a pulling force beyond the maximum rated capacity of the winch and possibly the wire rope. Such a condi-
tion can damage the winch, cause wire rope failure or result in injury to persons or property. Use low gear with extreme caution for slow speed
operation only. It is most important that the maximum operating pressure be restricted to permit a specifically limited winch line pull.

GMP reserves the right, without

equipment design or compo-
nents as progress in engineering
or manufacturing methods may
warrant.
• Wire rope lengths are based on the winch being equipped with a Model CH Level-Wind.
• Selection of the proper wire rope diameter, with a maximum breaking strength and allowable pull
appropriate for use on winches such as the CD-22 and CD-28, is the responsibility of the user.
