Description

Technical Field

[0001] The utility model relates to the technical field of gantry frames, in particular to a gantry frame which is easy to disassemble. Background Art

[0002] The gantry is a new type of small lifting gantry developed to meet the daily production needs of small and medium-sized factories for handling equipment, warehouse loading and unloading, lifting and repairing heavy equipment and material transportation. It is suitable for mold manufacturing, auto repair factories, mines, civil construction sites and other occasions that require lifting.

[0003] In the prior art, in order to ensure the strength of the gantry, reinforcement rods are arranged on the supporting legs of the gantry. The existing reinforcement rods are generally welded to the supporting legs, and the supporting legs are arranged to be unfolded. When the gantry is idle, it will take up a large space and is not convenient for storage. In addition, a warning light is installed on the gantry. When the gantry is working, the warning light is used to warn strangers not to approach, and the existing warning light is installed on the top of the gantry, which lacks protection. When the gantry is stored, foreign objects can easily touch the warning light and cause it to be damaged. For this reason, we have designed a gantry that is easy to disassemble to solve the above problems. Utility Model Content
