Leakage repair and protection of bridge crane

The reducer of the bridge crane trolley is often affected by factors such as vibration, wear, pressure, and temperature, resulting in oil leakage at the static sealing parts of each joint surface. The traditional governance method involves dismantling the gearbox, replacing the sealing gasket or applying sealant, but it is time-consuming, laborious, and difficult to ensure the sealing effect. Leakage may occur again during operation. Contemporary Western countries often use polymer composite materials for on-site treatment of leakage, and the most widely used ones include the Lucky Blue series. Polymer material repair can be done without disassembly, and the material has superior adhesion, oil resistance, and 350% tensile strength, which effectively overcomes the impact of gearbox vibration. The repair effect is more effective than traditional methods.
