Final answer:
The main difference between the hydraulic systems in a crane and a front end loader lies in their design for specific functions, with cranes lifting loads vertically and front end loaders manipulating materials horizontally, both applying the principle of hydraulic force multiplication.
Step-by-step explanation:
The difference between the hydraulic system on a crane and that on a front end loader involves their design and function. Cranes typically use hydraulic systems to lift heavy loads vertically, which requires a different arrangement of pistons and hydraulic fluid pressure to ensure stability and controlled lifting. A front end loader, on the other hand, uses a hydraulic system designed for scooping and loading material horizontally. Both systems use the principle that a small force applied over a small area can produce a much larger force over a larger area, as seen in the operation of hydraulic jacks.
The fundamental hydraulic principles remain the same in both systems; that is, they both employ mechanisms to convert hydraulic fluid pressure into mechanical force. However, the specific configurations and applications of these systems are tailored to the needs of the machinery, whether it's lifting vertically or manipulating loads on a horizontal plane.
