[0037] 4.2 Turning over and adjusting 4.2.12 truck cranes were used to lift the hydraulic cylinders 2m from both ends, with the lifting points symmetrically distributed to ensure that the lifting force on both sides was 11.4t. The hydraulic cylinders and support frames were slowly lifted and rotated 90° at a speed of 0.5° / s. 4.2.2 Place the tilted hydraulic cylinder onto the first frame, and secure the beam to the frame using eight ISO4017 standard M30×200-8.8Zn bolts and ISO7089 standard 30mm flat washers.

The embedment depth of the fixing bolts shall not be less than 300mm. 4.3.2 Use a level to check the levelness of the second frame. The deviation is 2mm / m. Level the frame by inserting 5mm thick shims at the bottom. Fix the tilting device to the frame with M24 bolts, tightening the bolts to a torque of 900N. m.

[0039] Step 5: Follow-up Processing 5.1 Component Storage 5.1.1 Place the disassembled screws, washers, and other small parts into a dedicated toolbox, classify them by model, and label them with quantity and specifications; 5.1.2 The hydraulic cylinder body is placed in the designated storage area and fixed at both ends with two temporary supports with a support height of 500mm to ensure that the hydraulic cylinder is placed horizontally and avoids direct contact with the ground.

[0040] 5.2 Tool Recycling 5.2.1 Clean up all tools, check for any damage, and then recycle them according to the tool list and store them in the designated location in the tool library; 5.2.2 Remove rust from reusable fasteners, apply rust-preventive grease, and then place them in a dry toolbox.
