Problems solved by technology

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 between 10-30cm, which cannot meet the needs of use
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 increases the transmission force. consumption

Abstract

Disclosed are a combined type light lifting apparatus and a method for using same. The combined type lifting apparatus comprises four lifting machines, a hydraulic system and a control device. The lifting machines are provided with inverted oil pumps and are symmetrically placed at the four corners to form a rectangle. Hydraulic oil cylinders (23) of the lifting machine oil pumps are connected to the hydraulic system, and the hydraulic system is electrically connected to the control device. The combined type lifting apparatus adopts a split structure and is convenient to transport, field assembly is facilitated, the oil pumps can be examined conveniently, and parts can be replaced conveniently, and an operator can move the combined type lifting apparatus conveniently; the combined type lifting apparatus is simple in structure, small in size and flexible and convenient to use.

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...
