1. Fixing method: The pulley is usually fixed to the steel pipe through a rubber lined curved card, which can provide stable support without damaging the surface of the pipeline.
2. Traction point setting: The traction point of the winch is located on the first small pulley, which can use the power of the winch to pull the pipeline forward and complete the assembly welding or other installation work of the pipeline.
3. Manual brake device: For safety reasons, a manual brake device is installed on each pulley to stop the movement of the pipeline when needed.
4. Construction requirements: Install pulleys at the front and middle parts of the crossing pipeline to ensure the smooth progress of the crossing work. This is usually determined based on design requirements and the weight of the pipeline to determine the required crane tonnage.
5. Insulation pipeline construction: Before threading the insulation pipeline through the casing, pulleys will be arranged according to the length of the insulation pipeline and the required number of carts will be calculated. At the same time, it is necessary to calculate the size of the pulley and pipe support based on the diameter of the insulation pipeline and sleeve.
6. Pipe jacking crossing engineering: In the development of urban modernization, non excavation construction methods, namely pipe jacking crossing engineering, are often used for pipeline crossing areas such as highways and railways. At this point, the pulley became an important construction tool.
