Problems solved by technology

[0002] At present, the tools used for railway line maintenance are manually carried to the car or from the car to the ground. Some heavy equipment requires several people to be lifted from the car to the line or from the railway line to the ground. On the vehicle, the labor intensity is high, the work efficiency is low, and there are unsafe factors
The existing maintenance and handling methods are no longer suitable for the requirements of modern railway construction and railway line maintenance. It is necessary to design a convenient and quick maintenance and handling device to meet the needs of railway engineering vehicle loading and unloading maintenance.

Description

technical field [0001] The invention relates to a vehicle-mounted lifting door device, in particular to a vehicle-mounted lifting door device for railway engineering. Background technique [0002] At present, the tools used for railway line maintenance are manually carried to the car or from the car to the ground. Some heavy equipment requires several people to lift from the car to the line or from the railway line to the ground. On the vehicle, the operation is labor-intensive, the work efficiency is low, and there are unsafe factors. The existing maintenance and handling methods are no longer suitable for the requirements of modern railway construction and railway line maintenance. It is necessary to design a convenient and quick maintenance and handling device to meet the needs of railway engineering vehicle loading and unloading maintenance. Contents of the invention [0003] The object of the present invention is to provide a vehicle-mounted lifting door device for r...
