Description

Construction small mobile crane

technical field

The utility model belongs to construction equipment, in particular to a small mobile crane for construction.

Background technique

Among the existing construction machines, large-scale hoisting machines are mainly used for bulky building materials. It is inconvenient to lift a small amount of heavy objects, and requires manual handling, which is time-consuming and labor-intensive. The cantilever of existing small-sized crane mostly is fixed in addition, can not change its height and length, is not easy to operate, also can increase the labor intensity of construction personnel.

The utility model is achieved through the following technical solutions:

A small mobile crane for construction, including a car body, the car body is provided with a boom and a lifting motor, the lower end of the car body is provided with rollers, the car body is equipped with a vertical rod, the upper end of the vertical rod is movably connected with the boom and The boom can be rotated and lifted, and the front end of the boom is provided with a block of pulleys.

The upper end of the vertical rod is provided with a connecting head, the lower end of the connecting head is arranged in the vertical rod and a ball is arranged between the inner wall of the vertical rod, and the upper end of the vertical rod is pressed by the end cover; the upper end of the connecting head is hinged with the boom.

The vertical rod is provided with an oblique support connected with the boom, and the oblique support is a telescopic rod.

The boom is a telescopic rod.

The vehicle body is provided with supporting legs, and the number of the supporting legs is at least three.

The car body is provided with handrails for moving the car body.

The utility model has the advantages that: the utility model adopts a telescopic boom, which can be adjusted in length and rotated 360 degrees, and the pulley set at the front end of the boom can save time and effort for construction workers when lifting small building materials. And can improve construction efficiency.

Fig. 1 is a structural representation of the utility model.
