Detailed Description

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in the attached figures 1-3: a micro crane comprises a crane body support 4, wherein a rotary body 3 is arranged on the crane body support 4, the rotary body 3 can rotate for 360 degrees, a suspension arm 1 and a fluctuation hydraulic cylinder 11 are arranged on the rotary body 3, specifically, the suspension arm 1 and the fluctuation hydraulic cylinder 11 are respectively fixed on the rotary body 3 through two different rotating shafts, and further, a telescopic rod of the fluctuation hydraulic cylinder 11 is supported on the suspension arm 1 to control the lifting of the suspension arm 1.

The upper end of the boom 1 is provided with a hook 12, and in the embodiment, a moment sensor for detecting the pulling force is arranged on the upper part of the hook 12

The automobile body support 4 is provided with a plurality of supporting legs 2 for supporting the automobile body support 4, the lower parts of two sides of the automobile body support 4 are provided with moving mechanisms, and specifically, the supporting legs 2 are axially symmetrically arranged on four corners of the automobile body support 4 through the supporting legs 2.
