Description

technical field [0001] The invention relates to a lifting platform, in particular to a lifting platform for underground cable construction. Background technique [0002] Some of the lifting platforms used in the existing underground cable laying process are built when they are used, and then dismantled after use, and repeatedly dismantled and built. The process is cumbersome and consumes a lot of manpower; Unstable, it is easy to cause the platform to fall due to sudden power failure, and there is a major safety hazard. For the transportation process of large-scale devices on the ground and underground, it needs to be transported to the lifting platform, which consumes manpower and low work efficiency. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a lifting platform for underground cable construction. [0004] The technical solution adopted by the present invention to solve the technical problem is: the lifting pl...
