AI Technical Summary
Traditional horizontal wheels suffer from problems such as insufficient strength due to their split structure, complex lubrication and maintenance, and poor adaptability, leading to safety hazards and increased modification costs.
The design features an integrated horizontal wheel axle and upper cover, combined with an independent lubrication channel and multiple sealing structures within the axle, achieving efficient lubrication without disassembly and improved wear resistance, while ensuring seamless compatibility with the original equipment.
It improves the structural strength of the horizontal wheels, avoids the risk of track pressure plates and bolts falling off, simplifies the maintenance process, reduces the transformation cost, and enhances the safety and efficiency of port operations.
