Problems solved by technology

[0002] As we all know, a crane is a kind of lifting equipment used to lift heavy objects, which is widely used in the field of industrial production. The supporting arm of this kind of crane cannot be too long because it is connected with the transmission device through a steel rope. If the supporting arm is too long, the crane is easy to fall due to the action of gravity when lifting heavy objects, and the stability is poor, which will cause danger to the operator.

Abstract

The invention relates to a movable crane which is movable and good in stability. The movable crane comprises a supporting arm, a crane jib, a transmission device, a steel wire rope, a hook and a base. The bottom end of the supporting arm is fixedly arranged on the upper surface of the base. The other end of the supporting arm is fixedly connected to the bottom end of the crane jib. One end of the steel wire rope is fixedly connected with an output shaft of the transmission device, and the other end of the steel wire rope is fixedly connected with the hook. The hook is hung at the top end of the crane jib. The crane jib is of a telescopic structure. Rolling wheels are arranged on the lower portion of the base. The transmission device is arranged above the base. The movable crane further comprises a supporting frame which comprises a tray, a supporting rod and a foundation bed. The bottom of a supporting plate is fixedly arranged at the top end of the supporting rod. The bottom end of the supporting rod is fixedly arranged on the foundation bed. When the movable crane is used, the top end of the crane jib can be arranged on the tray of the supporting frame.

Description

technical field [0001] The invention relates to a lifting device, in particular to a mobile crane. Background technique [0002] As we all know, a crane is a kind of lifting equipment used to lift heavy objects, which is widely used in the field of industrial production. The supporting arm of the crane cannot be too long. If the supporting arm is too long, the crane is easy to topple due to the effect of gravity when lifting heavy objects, and the stability is poor, thereby causing danger to the operator. [0003] In view of the above-mentioned defects, the designer actively researches and innovates, in order to create a mobile crane with a new structure, so that it has more industrial utilization value. Contents of the invention [0004] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a movable crane with good stability. [0005] The mobile crane of the present invention includes a support arm, a boom, a transm...
