Description

Technical Field

[0001] The utility model relates to the technical field of hoisting fixtures, in particular to a machine arm hoisting fixture for crane manufacturing. Background Art

[0002] A crane is a multi-action lifting machine that can lift heavy objects vertically and carry them horizontally within a certain range. It is also called an overhead crane, overhead crane, or crane.

[0003] A bridge crane is a lifting device that is horizontally mounted above a workshop, warehouse, or material yard to lift materials. Because its two ends are located on tall concrete columns or metal brackets, it looks like a bridge. The bridge of a bridge crane runs longitudinally along the tracks laid on the elevated platforms on both sides, making full use of the space under the bridge to lift materials without being hindered by ground equipment. It is the most widely used and most numerous type of lifting machinery.

[0004] The arm or beam of a bridge crane is usually quite large. When it is installed and assembled, it usually requires the cooperation of related lifting equipment to lift the arm / beam part and assemble it on two corresponding columns.

[0005] At present, the arm lifting clamp for crane manufacturing in the prior art usually pulls the two ends of the arm to lift the arm. During the pulling, due to the different sizes of the arms, the lifting clamp cannot adjust the clamping spacing, and clamps and fixes arms of different sizes. When lifted in the air, it is easy to shake, causing the arm to shake, which will cause the arm to separate from the lifting clamp, and there is a problem that arms of different sizes cannot be clamped. In addition, when clamping, the arm needs to be lifted so that the lifting clamp can clamp it on the arm, which requires cooperation from other equipment, and the lifting clamp cannot conveniently clamp the arm, so there is a problem that the arm cannot be conveniently clamped.
