Figure 1-27. Material Handling Crane (MHC), 30K Winches,
and Underlift Assembly (Cont)
b. 30K Winches. The left and right 30K winches (5) are located ahead of the MHC, and
stranded vehicles from the rear of the M1089. The 30K winches are rated for a 30,000
lbs (13,620 kgs) pull with only one full layer of cable on the winch drum. Pulling capacity
is reduced with each layer of cable that is added to the winch drum. Pulling capacity with
a full drum of cable is 15,830 lbs (7,187 kgs). 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 can be controlled from the WRECKER CONTROL PANEL (6) or from the wrecker
remote control (7) which is connected to a remote control connector by a cable. The 30K
winches respond to the remote control switches the same as they do to the levers at the
WRECKER CONTROL PANEL.
