Description

technical field

[0001] The invention relates to a movable jacking device, which belongs to the technical field of construction equipment. Background technique

[0002] At present, for the installation of some small pipe fittings, it mainly relies on manpower or the application of the chain to lift the pipe fittings, which is labor-intensive and low in efficiency, and the large lifting equipment is relatively large and inconvenient to move. And large lifting equipment cannot be implemented due to site restrictions. Even if the site allows the use of large-scale lifting equipment, the cost of large-scale equipment is quite high, and these problems will cause trouble for the industry. Contents of the invention

[0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a jacking device that is movable, easy to implement and improves labor efficiency.

[0004] In order to solve the problems of the technologies ...
