Study Notes

Hauling Unit Capacity

The minimum capacity of a hauling unit should be at least 1.5 to 2 times the bucket capacity.
The maximum capacity of a hauling unit should be at least 3 to 4 times the bucket capacity for a front shovel.

Front Shovels

The main use of hydraulic front shovels is for loading and hauling heavy materials.
Factors to consider when selecting a front shovel include the size of the job, the type of material being handled, and the terrain.

Loaders vs. Shovels/Hoes

The main difference between a loader and a shovel or hoe is the direction of the load: loaders lift and move loads forward, while shovels and hoes lift and move loads upward.
Another difference between a loader and a hydraulic excavator is the ability to excavate and swing loads, which is not possible with a loader.

Hydraulic Hoe Excavators

The main use of a hydraulic hoe excavator is for excavating and digging, often in tight spaces.
