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.
