Description
GROVE GMK 3055 Hydraulic Schematic
This GROVE GMK 3055 Hydraulic Schematic is a technical hydraulic circuit reference covering the crane’s superstructure and carrier hydraulic systems. The document is designed to help technicians understand hydraulic flow paths, component relationships, control circuits, and the various operating functions of the crane.
The schematic identifies major hydraulic systems including the slewing gear, luffing gear, telescoping gear, main hoisting gear, auxiliary hoist, counterweight hoisting system, cylinder locking and telescope locking systems. Hydraulic components are shown with their associated valves, pressure settings, motors, pumps, accumulators, sensors, and control connections.

Superstructure Hydraulic Circuit
The superstructure section provides a detailed hydraulic circuit diagram for the GMK 3055. It includes the hydraulic circuits associated with slewing, luffing, telescoping and main hoisting functions, together with locking and unlocking functions and emergency operation circuits.
The diagram also identifies hydraulic components such as axial piston motors, axial piston pumps, Servocom control valves, pressure accumulators, throttle and pressure valves, hydraulic cylinders and measuring points. Numerous pressure values, port designations and component identifiers are included directly on the schematic.
Carrier Hydraulic System
The document also covers the carrier hydraulic system, including Steering Circuit 1, Steering Circuit 2, all-wheel steering and carrier connections. The hydraulic schematic identifies the triple gear pump arrangement, hydraulic supply to the undercarriage, steering circuits and Servocom steering control components.
Major Hydraulic Functions Shown
- Slewing left and right
- Slewing brake release
- Main hoist raise and lower
- Auxiliary hoist raise and lower
- Luffing / derricking up and down
- Telescope extension and retraction
- Telescope locking and unlocking
- Cylinder locking and unlocking
- Counterweight lifting and locking
- Turntable pinning
- Steering circuits
- Emergency hydraulic operation
- Hydraulic accumulator circuits
Technical Information Visible in the Schematic
The drawings contain detailed hydraulic information including pressure ratings, flow information, cylinder dimensions and stroke values, motor and pump specifications, hydraulic ports, valve identifiers and measurement points. For example, the schematic references A2FM63 and A2FM16 Hydromatik axial piston motors, a P4 axial piston unit with load-sensing system (DRS), and multiple hydraulic pressure and measuring points.
The schematic also includes technical notes concerning hydraulic installation and commissioning. These notes specify that drain lines should be arranged so that motor and pump housings remain filled with oil, cylinders should be carefully bled before commissioning, adjustable hydraulic elements should be secured after adjustment, and hoses should be protected against damage at openings and rubbing edges.
Document Reference
The supplied drawing identifies the machine as GMK 3055 and the document as a Superstructure Hydraulic Circuit Diagram, with drawing reference 03078471. The carrier portion is identified with hydraulic schematic information for the undercarriage and steering circuits.
This document is particularly useful when tracing hydraulic circuits, identifying component connections, understanding pressure-control arrangements, and supporting hydraulic troubleshooting or repair work on the applicable crane system.
