Description

Technical Field

[0001] The utility model relates to the technical field of gate maintenance equipment, in particular to a gate maintenance synchronous jacking device. Background Art

[0002] The gate maintenance process involves gate jacking. At the bottom of the miter gate, due to the narrow space, it is difficult to put the hydraulic jack into place. Small gates are generally lifted by manpower. The lifting process is time-consuming, labor-intensive and asynchronous, and has high safety risks. Large gates generally use a synchronous lifting system to ensure that both sides or multiple sides of the gate can rise or fall synchronously to maintain the stability and balance of the gate. However, the synchronous lifting system has a complex structure, cumbersome installation, high operating cost, and difficult maintenance, which affects the gate maintenance period.
