Portable small-size hoisting apparatus
Technical Field
The invention relates to the field of hoisting, in particular to a portable small hoisting device.
Background
Lifting operations are an industrial process in which mechanical equipment or other objects are transported from one location to another using hydraulic lifts. Most hoisting machinery starts a vertical or vertical and horizontal working stroke after a lifting appliance takes materials, unloads the materials after the materials reach a destination, and then moves to a material taking place in an empty stroke to complete a working cycle, and then carries out second lifting. Generally, when the hoisting machine works, material taking, transporting and unloading are performed in sequence, and the work of each corresponding mechanism is intermittent.
However, most cranes are large in scale at the present stage, the application range of the crane is limited, the crane cannot be applied to small occasions, the crane is difficult to move, multiple persons are required to work together, and the working efficiency is reduced.
