Description

technical field

[0001] The invention relates to a hydraulic lifting operation platform for engineering maintenance and overhaul operations, in particular to a built-in hydraulic lifting platform for maintenance and overhaul operations of maglev track beams. It belongs to the field of rail transit engineering. Background technique

[0002] At present, the vehicle-mounted hydraulic lifting platform or elevator used for maintenance and repair operations, as well as the vehicle-mounted scissor-type hydraulic lifting platform or elevator, are all operating platforms above the entire hydraulic lifting system, and are used for climbing operations or high-altitude operations after being raised. , it can be lowered after the work is completed or usually does not work; and the track engineering vehicle used for the inspection, traction, maintenance and overhaul of the special maglev track beam for the maglev high-speed train needs to be located on the outside of the car body. , The s...
