Hydraulic Fluid and Pressure: These cylinders operate using hydraulic fluid, typically oil, which is pressurized by a hydraulic power unit or pump. The hydraulic pressure is controlled to extend or retract the cylinder, thereby extending or retracting the boom.

Safety Features:
Hydraulic mobile boom crane cylinders incorporate several safety features to ensure the stability and safe operation of the crane. These features may include:
Load Holding Valves: Load holding valves, also known as counterbalance valves, are often integrated into the hydraulic system to prevent uncontrolled descent of the boom in the event of a hydraulic pressure loss or system failure.
Overload Protection: Mobile boom cranes may be equipped with load moment indicator systems or other overload protection mechanisms to prevent the crane from operating beyond its safe lifting capacity.
Boom Angle and Length Sensors: Sensors are used to measure the boom angle and length, providing feedback to the crane's control system for accurate load positioning and preventing operation outside of safe operating ranges.
