Before relocating machinery and equipment, the overhead clearances of bridges and culverts along the travel route, as well as the load-bearing capacity of roads and bridges, should be ascertained. When crossing bridges, the machinery should be driven at a slow speed, and turning or braking on the bridge surface is prohibited. For bridges with insufficient load-bearing capacity, reinforcement measures must be planned in advance. Machinery and equipment must be installed on flat and solid ground; if soft ground is encountered, it must be compacted first, and base platforms of wood and boards should be added. Drilling machines operating on platforms must have a reliable connection between their base and the platform. Machinery and equipment must be installed securely and level. The vertical line of the rotation center of a rotary drill and the crane wheel groove edge of an impact (claw) drill must align with the pile hole position, with deviations not exceeding the design allowance (10-15mm). Protective railings or guards must be externally installed on the transmission parts (open gears, universal joints, belts, and pressure wheels) of the machinery and equipment, and钢丝绳 used for pressure wheels must be covered with protective sleeves. The thickness of the wooden boards laid on platforms (decks) must not be less than 50mm; when steel plates are used, anti-slip measures must be in place on the plate surface. Ladders, work platforms, and protective railings of the tower frame must be securely installed and reliable, with the net height of the protective railings not less than 1.2m. Cast steel parts must be used for pulleys and crane wheels, and crane wheels must have crane stoppers.钢丝绳提升限位器和防止钢丝绳跳槽的安全挡板 must be installed. The tower frame must not be installed below overhead transmission lines. During the vertical (installation) or horizontal (dismantling) of the tower frame, a certain safe operating distance must be maintained between the outer edge of the frame and the edge of the overhead transmission line, and it must comply with provisions of Article 2.0.16 and 4.0.17 of this regulation. During the installation, dismantling, and relocation of the tower frame, personnel must follow the unified command of the foreman or technical personnel. It is strictly prohibited to throw tools and objects up and down, to work simultaneously at the top and bottom of the tower, and to store dismantling tools and objects at high or elevated positions. When the tower frame is being raised or lowered as a whole, construction personnel must leave the area beneath the frame. When relocating equipment within the site, workers should first inspect and remove obstacles along the route, and a person must be assigned to supervise the cables to prevent damage. Unrelated personnel must be evacuated to a safe area. When moving platforms using tracks, drums, or rollers, workers must first check the safety of the tracks, pulleys, drums, cables, and support cylinders, and the movement should be as smooth and uniform as possible to prevent tipping. When relocating truck-mounted drilling machines, the masts must be lowered, cables and hoses removed, and the wheels must be immediately blocked with wooden wedges after the drilling machine is in place, ensuring the support legs are seated on the base platforms. When transporting machinery and equipment by truck, the items must be securely stabilized and tied down; loading and unloading should be supervised by experienced personnel. Overloading is prohibited. When manually loading and unloading vehicles, the gangplank must be of sufficient strength and equipped with anti-slip guards, with the slope not exceeding 20°; the end touching the ground must have anti-slip measures. The installation height of the tripod or frame of impact drills and claw drills must not be less than 7.5m, the angle between the two legs must not be less than 75°, the lower leg must be securely fastened, and a level pulling handle must be installed, with a safety factor of not less than 5. The safety factor for the wire rope must not be less than 6.
