MATERIAL HANDLING WITH EARTHMOVING EQUIPMENT.

Wheeled earthmoving machinery can be used for loading and carrying loose, stockpiled materials to central receiving areas that are served by a truck, conveyor or hopper, while tracked machinery can be used to handle hard, compacted materials and for operating on rough terrain with poor ground support. In any case, the coefficient of traction must be considered before the type of loader is selected. Machine productivity can be calculated by multiplying vehicle capacity in volume or weight times cycle time and an efficiency factor (the percentage of the hour that is actually worked).
