Small hydraulic crane with telescopic sections

Abstract

The invention provides a small hydraulic crane with telescopic sections. A rear section hydraulic cylinder, a load-bearing lifting arm, a load-bearing hydraulic cylinder and a front section hydraulic cylinder are cooperatively mounted above a chassis; the top of the load-bearing hydraulic cylinder is articulated with the middle part of the load-bearing lifting arm; the rear section hydraulic cylinder, the load-bearing hydraulic cylinder and the front section hydraulic cylinder are mounted on the chassis in a manner of hinging; the outer side of the chassis is successively connected with a second rear section, a rear articulation shaft and a first rear section through an articulation shaft; the outer side of a chassis frame is successively connected with a second front section, a front articulation shaft and a first front section through an articulation shaft. The small hydraulic crane with the telescopic sections is compact and simple in structure and reasonable in design; the problem that the conventional large crane is incapable of operating in small places is solved; the small hydraulic crane with the telescopic sections is flexible to use and transfer and high in safety coefficient and is applicable to roads and pavements of various terrains; the construction time is reduced; the lifting efficiency is improved.

Description

technical field [0001] The invention relates to a small crane, in particular to a small hydraulic crane with telescopic joints. Background technique [0002] At this stage, the cranes produced by major heavy-duty enterprises are not only large in size, heavy in weight, and cumbersome in shape, but also only suitable for use in sites with large building area, relatively flat, and low personnel density. For some relatively small construction sites or In downtown areas and residential areas with a large population, large-scale cranes cannot be used at all, and other lifting machines can only be used instead. Even if they are used, the crowd must be evacuated in advance, otherwise unnecessary safety accidents will easily occur; , For some construction environments with complex terrain and uneven road surface, the traditional cranes cannot be adjusted due to fixed wheels, and often cannot carry out normal construction operations. It is necessary to clean and adjust the road surfa...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem that the traditional cranes are large in size, heavy in weight and heavy in shape, and unable to carry out lifting operations in steep and complex terrain, the present invention provides a small hydraulic crane with telescopic joints, the small hydraulic crane with telescopic joints The structure is compact and simple, and the design is reasonable, which solves the problem that traditional large cranes cannot work in small sites. It is not only flexible in use and transfer, but also convenient in movement. It is also suitable for roads and roads with various uneven terrains, saving construction time.
