M1089A1 MATERIAL HANDLING CRANE (MHC), 30K WINCHES, AND UNDERLIFT
ASSEMBLY - Continued
30K Winches. The left and right 30K winches are located ahead of the MHC, and are
designed to be used for recovering disabled or stranded vehicles from the rear of the
M1089A1. Pulling capacity with one full layer of cable on the drum is 30,000 lbs (133,440
N). Pulling capacity is reduced with each layer of cable that is added to the drum. One
full layer of cable is the minimum amount of cable that may be left on the drum when
using the 30K winches. The 30K winches are rated for a 15,000 lbs (66,720 N) pull with a
full drum of cable. The 30K winches can be controlled from the WRECKER CONTROL
PANEL or from the WRECKER REMOTE CONTROL which is connected to a remote control
connector by a cable. The 30K winches respond to the WRECKER REMOTE CONTROL
switches the same as they do to the levers at the WRECKER CONTROL PANEL.
