A Tadano GR-750XL-2 is a single-cab rough terrain crane. It has a telescopic boom and outriggers, and it works on uneven ground where a truck crane can't get in. When one of these comes into the shop out of warranty, or arrives with no paperwork, the technician needs the workshop procedures before pulling anything apart. That's what this service manual is for.
What this manual helps you do
- Diagnose faults in the hydraulic power generating system, from pump output to circuit behavior.
- Rebuild outrigger, swing, boom elevating and boom telescoping components using the repair procedures.
- Adjust the winch system and verify the results against the manual's test steps.
- Troubleshoot the control system, safety system and electric system with the fault information a service manual like this usually carries.
- Replace parts in the driving power transmission, steering, brake and suspension systems with the removal and installation steps in front of you.
Who this is for
Crane service technicians, rental fleet mechanics and independent repair shops who fix these machines in-house. It also suits dealer technicians and plant maintenance staff who need a workshop reference for a GR-750XL-2 or GR-600XL-2.
