What is a key difference in the hydraulic systems of cranes compared to front-end loaders?

Cranes are designed to lift and move heavy loads vertically, and their hydraulic systems incorporate check valves primarily to maintain load control. These check valves prevent the hydraulic fluid from flowing back when the crane is lifting a load, ensuring stability and safety in the operation. This is crucial during operations where heavy loads are being suspended, as it prevents unintended descent.

In contrast, front-end loaders have different operational requirements that do not necessitate the same use of check valves. Their primary hydraulic function involves moving loads forward and backward, where the need for maintaining loads in a suspended position is not as critical. Thus, cranes are specifically engineered to handle the unique demands of lifting operations with features like check valves that enhance safety and performance.
