How does a hydraulic system work in a crane?

How Crane Hydraulics Work. … The pressurized hydraulic fluid pushes the piston in and out of the cylinder, allowing the piston to lift or move a load. With hydraulic systems in cranes, there are typically two different pistons. When one piston is compressed, the displaced oil forces the other piston to extend.

What is the hook on a crane called?
