How do hydraulic cranes work?

Hydraulic cranes operate using the principles of hydraulics, which involve the transmission of force through a fluid. They utilize a hydraulic system that includes a pump, cylinders, and fluid to create movement. When the pump moves hydraulic fluid into the cylinders, it generates pressure that extends or retracts the crane's arms or boom. This allows the crane to lift heavy loads with precision and control, making it effective for various construction and industrial tasks.
