AI Technical Summary
The existing bridge-building machine's mobile frame and construction platform have high sliding resistance and are difficult to slide. Furthermore, the stainless steel plate is prone to problems such as bulging and swelling during the sliding process. Thick stainless steel plates are costly and increase the machine's weight.
The sliding top surface of the bridge-building machine platform has a multi-layer structure, using composite steel plates made of different materials, including stainless steel and ordinary steel plates with low coefficient of friction. Through the design of the claws and shoes, the sliding friction is reduced, improving sliding stability and economy.
It effectively reduces sliding friction resistance, improves the moving efficiency and stability of the bridge construction machine, avoids damage to the sliding top surface during the sliding process, and reduces its weight and cost.
