Grove GMK5095 Crane Circuit Diagrams

On a GMK5095, you’re working a lot on tight sites and rough ground—lifting heavy picks all day with the chassis, steering, and superstructure systems all talking to each other. These circuit diagrams are what I grab when I need to trace how air and hydraulic circuits are actually routed on the crane, not just guess from experience. If, for example, the outriggers won’t build pressure or the steering feels dead in one direction, this is the document that lets me follow the lines, valves, and controls step by step to isolate where the problem is.

Applications & Use Cases

• Trace compressed air lines to find leaks, stuck valves, or clogged components affecting brakes or suspension.
• Follow chassis hydraulic circuits to verify pump flow paths and diagnose slow or weak functions.
• Check steering hydraulics when the crane pulls, steers unevenly, or has intermittent assist.
• Inspect superstructure hydraulic routing to troubleshoot boom, swing, and winch performance issues.
• Confirm hose and line routing after component replacement so everything is reconnected correctly.

FAQ

Q: Can I use this on a tablet in the field?

A: Yes, it’s handy on a tablet so you can zoom in on specific circuits right next to the crane.

Q: Is it worth printing parts of this manual?

A: Many techs print the diagrams they use most, laminate them, and keep them in the service truck for quick reference.

Safety Note

Always depressurize and secure all crane systems before opening, disconnecting, or testing any circuit shown in these diagrams.
