double-faced. Single-faced pallets (fig. 7-13, views A

pallet (fig. 7-12) has platforms on the top and the
transport loads of long and heavy supplies such as pipe,
lumber, and steel. The straddle truck (figure 7-11) is
used as an efficient conveyance for intra-station
movement of palletized material at many supply
activities. Straddle trucks offer a faster and more
efficient method of moving unitized pallet loads over
intermediate distances than the tractor-trailer train.
The pallet sling (figure 7-12) is used for overhead
lifting of palletized loads by a crane or ship's boom.
Normally, a cable is used for the sling, but a line or
chain may be used, depending on the weight of
material to be lifted.
Slings have rigid horizontal supports at the base,
usually made of steel bars or pipes. The horizontal
support must be strong enough to distribute the load
across the entire length. Some slings have movable
spreader bars at the top to prevent crushing the load
while it is being lifted.
A pallet is a wooden, steel, or aluminum platform
on which supplies are loaded, transported, or stored in
units. Use of pallets permits handling the material with
