Shoring

by laying wood on top of the scales and driving the dozer onto the wood. The sum of the weight of the scales provides the GVW. Once all the weights have been computed, they are marked on both sides of the vehicle and are annotated on the manifest list. The vehicle is then staged on the scheduled chalk. Members of the air det must be highly qualified in both vehicle and cargo weighing and marking procedures because upon completion of the mission, the air det is responsible for mounting itself out to return home. SHORING Shoring is required for any type of equipment or cargo that can create metal-to-metal contact aboard the aircraft. Shoring for individual equipment is usually precut, banded, and marked with the USN number of the equipment and accompanies the piece of equipment on the aircraft. The weight of the shoring must be included in the weight of CESE. The shoring is placed on CESE at the weighing and marking station which should be close to the location where the shoring is to be used. Roller shoring (fig. 2-9) is required for tracked equipment. Roller shoring protects airport parking ramps and the cargo floor or loading ramps of cargo aircraft. Parking shoring (fig. 2-10) is required for grader blades, front-end loader buckets, rollers, and so forth. Any vehicle requiring roller shoring requires parking shoring. The minimum thickness of parking shoring is three-fourths inch. Parking shoring is also required Figure 2-10.—Parking shoring. 2-9
