1-16. WINCH SYSTEM
The winch system operates hydraulically and consists of two main winches (1 and 2) and an auxiliary
winch (3). The main winches operate independently and are used to recover, load, and unload heavy
tracked and wheeled vehicles. The main winches are mounted side-by-side directly to the winch
platform. Each main winch has a maximum capacity of 55,000 lb (24,947 kg). The auxiliary winch is
used to pull the main winch cable back to the payload. The auxiliary winch is mounted to the winch
platform just below the driver's side main winch. The auxiliary winch has a maximum capacity of 3000 lb
(1361 kg). The winches are controlled from the operator's station (4). The operator is protected by a
shield during winch operations.
Each main winch incorporates a two-speed hydraulic motor (5 and 6). A single-speed motor (7) is used
by the auxiliary winch. A Power Takeoff (PTO) driven hydraulic pump (8) supplies winch system with
hydraulic oil from a 45 gal (170 L) reservoir (9). A view gage (10) on the reservoir indicates the hydraulic
oil level. All winches have a fail-safe, spring-loaded brake. The brake will automatically set when winch
control is in neutral posit on or when hydraulic pressure is less than 270 psi (1862 kPa).
