HSMC ROTO-30 Hydraulic Pump
Roto-30 pedestal offshore crane’s hydraulic pump is a double stage vane pump rated at 180 Lpm / 2500 psi, the pump it self is a special design pump from vickers.
HSMC ROTO-15 Main Control Valve
Roto-15 cranes can be designed for a single load system or double load system ( main load and aux load ), if the crane designed for double load system then the hydraulic system use 4 stack of commercial shearing control valve ( A series ).

Improvement in Efficiency with Load Sensing
Load sensing was developed to improve the efficiency of a circuit. It requires a variable displacement pump; thus, it is appropriate to discuss it here.
Hydraulic Flow Control Valves
Flow control valves are used in constant-flow (fixed displacement pump) circuits to control actuator speed. The simplest type of flow control valve is a needle valve. Another name for a needle valve is a non-pressure-compensated flow control valve. Turning the manual adjustment on a needle valve causes the needle to move [...]
