摘要： A truck body adapted for drilling has a movable auger rack mounted beneath the bed of the truck. A worker can lift an end of an auger vertically without reaching, since the augers in the rack may be moved outboard of the truck bed. The rack is operatively connected to drive means, preferably of a hydraulic variety. The rack is a skeleton structure adapted for carrying drilling augers and especially hollow stem augers. A pair of parallel tracks traverse the major axis of the truck bed on the undercarriage side of the bed. A dolly structure is mounted on rollers. The rollers ride in and are held by the track. The rack is attached to the dolly structure. The dolly structure carries the entire weight of the rack, cantilever fashion, in all positions defined by rack movement. Those positions include at least a first position where the rack is concealed beneath the truck bed and a second position where the rack is extended outwardly of the truck bed.
