3.3 Trucks

Trucks are particularly useful when the material moved varies frequently in size,
shape, and weight, when the volume of the parts or material moved is low,
and when the number of trips required for each part is relatively small. There
are several trucks in the market with different weight, cost, functionality, and
other features. Hand truck, fork lift truck, pallet truck, platform truck, counter-
balanced truck, tractor-trailer truck, and automated guided vehicles (AGVs) are
some examples of trucks (see Figure 1.7).
