What This Manual Provides

The Mitsubishi 30t x 24m (R) hydraulic deck crane manual is not a generic crane guide. It is a document set tied to a specific installation – four cranes per vessel (No. 1 through No. 4) – and it shows the actual component arrangement, hydraulic circuit layout, and control logic used on this equipment. The instruction section explains how the hoisting, luffing, and slewing motions are controlled through fixed-displacement hydraulic pumps and motors, how the counterbalance and relief valves protect the system, and how the operator’s cab controls are laid out. The maintenance portion covers the mechanical, electrical, and hydraulic systems in detail, including inspections, adjustment values, and replacement criteria for wear parts.

For a technician or crew member already working with this crane, the value is in having the manufacturer’s procedures and reference drawings available without digging through a ship’s document locker. The hydraulic diagrams, exploded views, and wiring references help trace faults, confirm component locations, and plan repairs. The safety device section explains the limits, detectors, and interlocks that stop the crane when something goes out of range – useful for understanding why the crane has stopped and how to restart it correctly after a limit actuation.

Systems and Components Documented

The hydraulic section covers the vane-type double pump (T6EE + T6C), the RM radial piston motor used for hoisting, the Dowmax MB350AS200 motor used for slewing and luffing, counterbalance valves, control valves, relief valves, sequence valves, the oil cooler, the line filter, the oil tank, and the associated piping. The electrical section covers the 105 kW continuous / 240 kW ED15% main pump motor, the fan cooler motor, the starter panel, the control stand, the slip ring, and the lighting and heating circuits. The mechanical section covers the hoisting and luffing winches, the slewing device, the turn table bearing, the jib and post structure, the wire ropes, the sheaves, the falling block, and the operator’s cab.

Safety Devices and Operating Limits

The manual documents the hoisting upper and lower limits, the collision-prevention limit between the jib tip and falling block, the luffing upper and lower limits, the jib rest limit, the hoisting wire rope looseness detector, the oil level float switch, the working oil temperature limits (cooler ON at 50°C, OFF at 35°C; upper limit 75°C), the main motor overload protection, the emergency stop button, and the handle off-notch interlock. Restart procedures after each safety device actuation are described in sequence, including the neutral-position reset and buzzer-reset steps.

Who This Manual Is For

This Mitsubishi hydraulic deck crane instruction manual is intended for crane operators, shipboard maintenance crews, marine engineers, and shipyard personnel responsible for the 30t x 24m (R) installation. It assumes the reader is working with the actual crane and needs the manufacturer’s procedures, component references, and system descriptions. The bilingual format helps where the original Japanese terminology is still used alongside English translations. It is not a training course and does not replace the onboard safety instructions or the classification society requirements – it is the technical document set for this specific crane model.
