Roller Cradle
As a safe and efficient transportation method, Long-Distance Pipelines are generally laid underground. The essence of pipeline lowering is the translation of the pipeline, which moves the pipeline along the direction of the trench into the trench. If it is in a straight pipe section, the change in point position during translation has no impact on the pipeline; If there is a bend on the pipeline, the bending point will also shift during the translation process, causing changes in the bending point and greatly affecting the quality of the trench. At present, the application of slings for long-distance pipeline trench laying operations has resulted in slow speed, low efficiency, lack of safety guarantee, long construction period, and inability to continuously operate, which can easily damage the pipeline anti-corrosion layer. The Roller Cradle for Pipelaying in Pipeline Construction is a specialized lifting and auxiliary walking equipment used during the trench lowering operation after the completion of pipeline welding, and is used in conjunction with the pipe crane. Use a pipe crane to lift the lifting equipment for pipeline laying with anti-corrosion coating. The applicable pipeline specification range is 150-1500mm. ZH Company provides a new type of Roller Cradle for Pipelaying in Pipeline Construction, which can significantly improve the speed of trench pipe laying operations, increase efficiency by nearly 10 times, be safe and feasible, and can operate continuously without damaging the pipeline anti-corrosion layer.
