[0002] In construction projects, cranes are usually used to transport materials. A crane is a piece of mechanical equipment specially used at construction sites. Its main function is to achieve vertical lifting or vertical lifting and horizontal movement of heavy objects. As an indispensable and important equipment in construction, the selection and use of construction cranes are of great significance to improving construction efficiency and ensuring construction safety. Cranes often require anti-dumping devices, some of which are built-in and some are added manually later. The anti-dumping device of a construction crane is an important safety equipment to ensure the stability of the crane during use and to prevent the crane from overturning due to various reasons.

[0003] By comparison, the Chinese patent with authorization announcement number CN212639743U discloses an anti-dumping device for a crane for construction engineering, including a connecting plate, a hinged ear bolted to the bottom of the right side of the connecting plate, a support plate hinged inside the hinged ear, wheel frames bolted to both sides of the bottom of the support plate, a running wheel rotatably connected inside the wheel frame, a card frame bolted to the top of the right side of the connecting plate, a connecting frame bolted to the right side of the top of the support plate, a card block clamped inside the card frame, a card strip clamped inside the connecting frame, a card rod clamped between the holes of the card frame and the card block, a fixing rod clamped between the holes of the connecting frame and the card strip, and a support frame bolted between the right sides of the card block and the card strip.
