The invention relates to the technical field of cranes, in particular to an overload limiter structure of a bridge crane, which comprises crane bridge guide rails, a cart moving cross rod is slidably mounted at the upper ends of the two crane bridge guide rails, a first limiting groove is formed in the upper end of the cart moving cross rod, and a travelling trolley is slidably mounted at the upper end of the first limiting groove. A trolley limiting block is fixedly installed at the lower end of the running trolley and slidably arranged in the first limiting groove, the clamping mechanism comprises an overload limiter containing shell, the overload limiter containing shell is fixedly connected with the first connecting rod, and an alarm is fixedly installed on the side wall of the overload limiter containing shell. A rectangular sliding groove is formed in the center of the upper end of the overload limiter containing shell, strip-shaped sliding grooves are formed in the two sides of the inner wall of the rectangular sliding groove correspondingly, and first inner grooves are formed in the inner walls of the two strip-shaped sliding grooves correspondingly, so that the equipment can effectively prevent heavy objects from falling under the emergency situation, and the safety of operators is guaranteed.
