1-17. 11K SELF-RECOVERY WINCH (SRW)
Figure 1-17. 11K Self-Recovery Winch (SRW)
When specified, the vehicle is equipped with an 11K Self-Recovery Winch (SRW) (1, Figure 1-17) mounted on the right
frame rail. The SRW is rated for 11,000 lbs (48,924 N) pull when the winch drum has one full layer of cable. One full
layer of cable is the minimum amount of cable that may be left on the drum when using the SRW. Pulling capacity is
reduced with each layer of cable that is added to the winch drum. Pulling capacity with seven full layers of cable on
the winch drum is 6,780 lbs (30,157 N). The SRW cable may be routed to the front or rear of the vehicle for recovery
operations. The SRW is equipped with a fail-safe brake which is spring applied and hydraulically released. The fail-
safe brake is automatically applied when hydraulic pressure falls below 270 psi (1,862 kPa). The fail-safe brake will
hold the load until hydraulic pressure is restored. The winch control valve functions as a throttling valve when cable
is being payed out. The winch control valve controls the flow of fluid to the winch motor. When cable is being pulled
in, the winch control valve acts as a free flow check valve. The winch control valve is preset at the factory and is not
to be adjusted under any circumstances.
