SELF- AND LIKE-VEHICLE RECOVERYA winch-equipped mired vehicle can performself-recovery. Attach the snatch block to a suitableanchor and the free end of the cable to a chain slingconnected to both of the front lifting shackles of themired vehicle. A fixed block provides a mechanicaladvantage on a self-winching operation, even though thesheave of the block is performing as a first-class lever.(See fig. 5-12.)Use a similar wheeled vehicle as the source of effortto perform recovery by towing and winching. Forvehicles not equipped with lifting shackles, attach a towchain to the main structural members. Before towing orrecovering a disabled vehicle, check the vehicleoperator’s manual to ensure that all physical and safetyfeatures are considered. This must be done to preventadditional damage to the disabled vehicle.To recover a mired truck by towing with a similarvehicle, use a tow chain or a wire rope sling between thetowing vehicle and the mired vehicle. Attach it to onelifting shackle of the mired vehicle and through the towpintle on the towing vehicle.Apply power slowly to prevent shock to the towingdevice and lifting shackles. If one towing vehicle cannotattain sufficient towing effort to overcome theresistance, use another towing vehicle in tandem withthe first, as shown in figure 5-13.Figure 5-11.-Cross-country tow.Figure 5-12.-Self-winching.Figure 5-13.—Like-vehicle recovery.5-11
