Description

technical field

[0001] The invention relates to a portable combined lifting device and its usage method. Background technique

[0002] At present, the lifts used in the maintenance industry mainly use fixed lifts, which are inconvenient to move, and cannot be effectively solved for some special occasions. At present, mobile lifts are mainly mechanical or hydraulic jacks. Mechanical jacks are inflexible to use and inconvenient to carry; hydraulic jacks are easy to use and have a wide range of applications. The lifting height of existing jacks is all between 10-30cm, which cannot meet the use requirements. Moreover, the existing lifts are all installed with upright oil pumps. At the same time, the chain is used as a transmission to drive heavy objects to lift. This increases the mechanical structure, increases the overall weight, and also increases the transmission force. consumption. Contents of the invention

[0003] In order to overcome the deficiencies of the prior a...
