Terex RT45, RT45L Wheeled Cranes Operation and Maintenance Manual
The Terex RT45 and RT45L Wheeled Cranes are designed for mobility and reliable lifting power in construction, utility, and field environments. This Operation and Maintenance Manual walks through daily setup procedures, boom and winch operation, steering behavior, hydraulic patterns, and long-term maintenance tasks. Technicians depend on it when diagnosing brake fade, hydraulic drift, or inconsistent boom speed.
Applications & Use Cases
-
Operating the cranes safely in rough or uneven terrain
-
Maintaining hydraulic and steering systems
-
Understanding boom load capabilities and stability rules
-
Diagnosing powertrain or braking issues
-
Planning preventive maintenance intervals
FAQ
Does the manual cover both RT45 and RT45L models?
Yes. Differences in lift geometry and configuration are included.
Are hydraulic diagrams provided?
Yes. Full routing diagrams for major circuits.
Safety Note
Ensure wheel chocks are placed before any maintenance requiring boom elevation.

- In compliance with the safety regulations, the crane truck is equipped with:
- 1. Lifting limit stop device that blocks the manoeuvre, preventing the block from getting too close to the boom head.
- 2. A “three dead turns” lowering limit stop device that prevents complete unwinding of the rope from the winch drum.
- 1. Make sure the gearshift lever is in the neutral position “N”.
- 2. Select the fast or slow gears according to needs (where applicable).
- 3. Turn the ignition key.
- 4. The battery level, braking system air circuit, engine oil pressure and coolant temperature warning lights on the instrument panel come on.
- 5. Beep the horn.
- 6. The parking brake must be applied.
- 7. Turn the ignition switch to the second position to start the engine.
