a . Purpose of the Ve h i c l e . The medium wrecker (M816) is used to return disabled vehicles forr e p a i r, and to free mired vehicles. The vehicle crane is used for lift ing operations of up to 20,000pounds (9,080 kilograms). Examples of M816 crane operations are:

( 1 ) Removing and replacing engines, power packs, and gun tubes.

( 2 ) Loading and unloading munitions.

b . P er f o r ma n c e . The medium wrecker (M816) has a hydraulically-powered, engine-driven crane,and drive shaft-driven front winch, and rear winch. The front winch is used mainly for freeing themedium wrecker when it becomes mired, or for assisting rear winch by acting as an anchor point. T herear winch is used as a heavy-duty apparatus because of its heavy pulling capability. The crane, whichcan extend from 10 to 18 feet (3.05 to 5.49 meters), is used for lifting loads up to 20,000 pounds( 9 , 080 k i l o g ram s) .

a . Purpose of the Veh i c l e . The M817 dump truck is used to transport materials such as sand, gravel,and stone. It may also haul scrap, rubble, or other waste materials. These vehicles operate on or off theroad with load limits up to 10,000 pounds (4,540 kilograms). Fully loaded, this vehicle can tow trailers

with up to 15,000 pounds (6,810 kilograms). This vehicle has a welded-steel dump body. The forwardend of the solid dump body extends up and over the vehicle cab to protect it from damage duringloading. Troop seats may be positioned for troop transport operations.

b . P er f o r ma n c e . This truck has a tailgate that can be opened at either the top or bottom, allowingoperation as a regular (end load) type, rocker type, or as a spreader type dump truck.

a . Purpose of the Ve h ic le . The M818 tractor truck has a fifth wheel used to haul semitrailer loadsup to 37,500 pounds (17,025 kilograms) maximum (refer to table 1-3). When connected to as e m i tr a i l e r, the fifth wheel pivots up, down, and sideways, to allow for changes in the road. T his

vehicle comes equipped with a front winch, making it more versatile in tactical operations underd i fficult field conditions. This vehicle also comes equipped without a front winch.

b . P e r f o r m a nce . The M818 tractor truck can ford hard-bottom water crossings up to 30 inches( 7 6. 2 centimeters) without a deepwater fording kit, and 78 inches (199.1 centimeters) with the kit.

c . Special Limitations. Fifth wheel cannot pivot more than 21 degrees up, 15 degrees down, or7 degrees sideways. For this reason, semitrailer operations cross-country are limited to gradual gradesover known terrain.

a . Purpose of the Ve hi cle. The M819 tractor wrecker truck has a hydraulically-powered, engine-driven crane, a front winch equipped with a level winding device, and a fifth wheel for pulling a trailer.The crane, which can be extended from 11-1/2 to 26 feet (3.51 to 9.93 meters), is used for lifting loads

up to 20,000 pounds (9,080 kilograms). the vehicle is used for freeing mired vehicles, lifting materialsfor loading and unloading operations, and for towing trailers.

b . Pe r fo rm an c e . The M819 tractor wrecker truck has a hydraulically-operated crane with threeposition booms, capable of 270 degrees rotation and approximately 45 degree elevation. Afifth wheel,or semitrailer coupler, is mounted on rear of M819 tractor wrecker truck. The base of the fifth wheelpivots on a walking beam which pivots on the subbase. This constructions permits the fifth wheel tomove in all planes. The front winch is used to free vehicle should it become mired.

a. Differences. The M820 expansible van t ruck ha s windows, heating an d air-conditioning systems, and uses outside electric power. The M820A1 expansible van truckdoes not h ave windows, nor air -conditioning system; but does ha ve a h eating system . The

M820A2 expansible van tru ck has windows, hydrau lic liftgat e, heating, an d air-conditioning system.b. Purpose of the vehicles. The M820 and M820A2 expansible vans transport

electr onic base st at ions in to th e field. The M820A1 expan sible van can be u sed for thesame operat ion. In th e tr aveling position, van tr uck bodies ar e 17 feet long by 8 feet wide(5.2 meters long by 2.4 meters wide). When in the field, van sides are expanded to give awidth of nearly 14 feet (4.3 meters). They may serve as communication stations orelectr onic repair sta tions. The vans ar e designed to carry u p t o 5,000 pounds (2,270 kilo-grams) of equipment into the field. The M820A2 expansible van is equipped with ahydra ulic liftgat e, which m akes it th e preferred vehicle to use when heavy, delicateelectronic equipment has to be moved in or out of van.

c. Performance. All three expansible vans have a minimum turning radius of 47 feet,4 inches (14.54 meters, 102 centimeters).
