A loader is commonly used to move a stockpiled material from ground level and deposit it into an awaiting dump truck or into an open trench excavation.
Loaders are used mainly for loading materials into trucks, laying pipe, clearing rubble, and digging. A loader is not the most efficient machine for digging as it cannot dig very deep below the level of its wheels, like a backhoe or an excavator can. The capacity of a loader bucket can be anywhere from 0.5 to 20 m3 depending upon the size of the machine and its application. The front loaders bucket capacity is generally much bigger than a bucket capacity of a backhoe loader.
Estimating Bucket Capacity
Volume = Cross Sectional Area x Length
