TM 9-2320-361-10 2-31. OPERATION OF PIPELINE CONSTRUCTION MAINTENANCE TRUCKS a. General. The M756A2 pipeline construction truck has an open top metal body with a wood-metal reinforced flatbed. The truck is equipped with a rear winch, a winch and cab protector, two gin poles for constructing an A-frame, two 24-volt floodlights, a tailboard roller, a custom made toolbox, and stiff leg jacks for additional support. Weather protection for personnel and equipment is provided by a cargo body tarpaulin, with end curtains supported by top bows. Front and side cargo body panels with racks support the top bows. These panels and racks are easily removable for side loading. The side cargo racks have built-in troop seats so that the truck can be used as a personnel carrier when necessary. Additional personnel will be required for operating M756A2 trucks. b. Operating the Rear Winch. All personnel must stand clear during hoisting and lowering operations. A shifting or swinging load may result in injury or death to personnel. When hooking up for winching operations, position throat (open part) of hook (12) upward in case overloading straightens out hook (12). Failure to do this may result in injury or death to personnel. (1) Place truck so winch (9) is in direct line with load (11) to be pulled or lifted. (2) Apply parking brake lever (6), place transmission gearshift lever (1) in “N” (neutral) position, and shut off engine (refer to para. 2-17). (3) Set wheel chocks (10) behind rear wheels, and lower tailgate (3) (refer to para. 2-25). 2-147 WARNING
