Description

Technical Field

[0001] The utility model relates to the technical field of counterweight mechanisms, in particular to a counterweight mechanism for a crane. Background Art

[0002] The crane counterweight mechanism is an important stabilizing device of the crane. The crane counterweight mechanism improves the stability of the crane through counterweight, prevents dangerous conditions caused by external environmental influences, and effectively ensures work and personnel safety. By installing reasonable counterweights, work efficiency can be improved, and the horizontal transportation distance and height can be increased. Reasonable counterweights can reduce the wear and failure rate of the crane.

[0003] For example, a quick counterweight mechanism for a crane is described in the patent document with the announcement number CN217025131U. After the two counterweight blocks are clamped together, they are fixed by two fixing devices, which simplifies the steps of adding and installing the counterweight blocks, makes it convenient for users to adjust the weight of the counterweight blocks on the crane, and adjusts the position of the two fixing rods by rotating the turntable, which makes it convenient for users to install and remove the two counterweight blocks by rotation, thereby improving the installation efficiency of the counterweight blocks. This quick counterweight mechanism for the crane is not convenient for adjusting the center of gravity, which brings hidden dangers to the crane transportation work in a working environment with an inclined ground. This quick counterweight mechanism for the crane can only be fixed to a single-size crane fixed structure, and its applicability is limited.

[0004] Based on this, a crane counterweight mechanism is now provided, which can eliminate the disadvantages of the existing device. Utility Model Content
