Abstract

The invention relates to a diesel hydraulic lifting machine. The diesel hydraulic lifting machine comprises a support frame device part, a power device part, a hydraulic device part, a lifting and pulling device part and a rotary device part. According to the invention, power is provided through a diesel engine, and control power is provided through a hydraulic motor, and the stable running is achieved when loaded objects fall off by utilizing a balanced valve operating principle.

Description

Technical field [0001] The invention belongs to the field of mechanical hoisting, and particularly refers to a diesel hydraulic hoist. Background technique [0002] For lifting materials under 300 kg, or for residents of high-rise buildings, who can easily lift heavy daily necessities from downstairs and lift and unload small goods in various occasions, hoisting machines are the best choice. Because of its simple structure, easy installation, compactness, and single-phase power source, the hoist has a wide range of uses. This kind of small crane is also called electric hoist, and it is also widely used in modern industrial production lines, assembly lines, assembly machines, logistics transportation and other occasions such as machinery manufacturing, electronics, automobiles, shipbuilding, workpiece assembly, and high-tech industrial zones. For work in warehouses, docks, ingredients, hanging baskets and working places with narrow space, it can show its excellent quality. It is...
