To operate the SANY STC250T4 25 Tons Lifting Capacity Truck Crane, please follow the instructions provided in the owner's manual. Here is a step-by-step guide:

1. Familiarize yourself with the crane's features and technical specifications mentioned in the manual, such as the boom length, outrigger span, hydraulic system, and control panel.

2. Before operating the crane, ensure that the diesel engine is filled with Grade IV diesel and urea solution conforming to related national standards. Refer to the operating instructions and related standards for details.

3. Make sure the crane is on a level surface and the outriggers are properly extended and secured. The outrigger span is expanded to 5.18m×6.4m, providing a stable base for lifting operations.

4. Start the engine and allow it to warm up. The crane is equipped with a DF Cummins ISLe290 30 engine and a FAST 9-speed synchronizing gearbox.

5. Use the smart control features of the crane, such as the CAN-BUS system for instant transfer of information and the 7' color display and smart panel for user-friendly operation.

6. Use the load sensing hydraulic system for higher efficiency with less consumption. The constant-pressure powered luffing allows for smooth luffing down, free from the impact of load fluctuation.

7. The crane has a 35m telescopic boom with a reach of up to 35.5m. The boom section overlap is increased for higher torsion resistance and bending resistance. There is also an 8m lattice jib for stable operation.

8. The crane is equipped with a main winch and an auxiliary winch, both capable of a max single line pull of 5 tons. The winches have a rope diameter/length of 16mm/165m for the main winch and 16mm/95m for the auxiliary winch.

9. The crane has a slewing speed of 2.5r/min and a luffing speed of 45s/55s (up/down). The telescoping speed is 55s/45s. The outrigger jack can retract in 30s and extend in 15s, while the outrigger beam can retract in 25s and extend in 20s.

10. Refer to the load chart provided in the manual for the crane's lifting capacity at different boom angles and jib offset angles. Make sure to operate within the specified load limits and follow the safety guidelines mentioned in the manual.

Please note that this is a general overview of operating the SANY STC250T4 25 Tons Lifting Capacity Truck Crane. For detailed and specific instructions, it is recommended to refer to the owner's manual provided with the crane.
