This utility model provides an anti-tipping
gantry crane, including a track parallel to the ground, a ground pole
assembly parallel to the track on the ground beside the track, a trolley slidably mounted on the track, outriggers on the top of the trolley, a crossbeam between the tops of two sets of outriggers, a lifting device on the crossbeam, and sliding clamping mechanisms that cooperate with the ground pole
assembly at both ends of the trolley. In this utility model, the sliding clamping mechanism is slidably connected to the ground pole
assembly through a sliding seat, which enhances the connection stability between the two ends of the trolley and the ground. The sliding seat is not easy to slip off the ground pole assembly, making the crane less prone to
instability and tipping. The clamping assembly can clamp and fix the crane to the ground pole assembly, preventing the crane from colliding with the end limit device under
wind force and tipping over, thus ensuring its anti-tipping effect.
