The invention relates to a crane damping and disaster avoiding energy dissipation support which comprises a steel box support. A longitudinal supporting base assembly is arranged at the position of the edge of the top face of the steel box support, a top supporting plate is fixedly installed on the top of the longitudinal supporting base, an inclined groove is formed in the position, on the innerside of the longitudinal supporting base, on the steel box support, the bottom of the inclined groove communicates with an energy dissipation bin arranged on the inner side of the steel box support, and damping energy dissipation devices are arranged in the energy dissipation bin and the inclined groove. When accidents happen, absorption and energy dissipation can be effectively achieved, the accidents can be reduced and avoided, the damping and disaster avoiding functions are achieved, vibration energy spreading achieves better energy dissipation and absorption, the tension and damping energydissipation capacity is achieved, and serious consequences caused by disasters are avoided.
