Abstract

The utility model relates to material carrying and hoisting transportation technical equipment, and discloses a balance hoisting device which comprises an I-shaped mounting rod, a supporting rod, a chassis structure, a supporting structure, a hydraulic adjusting structure and a suspension arm structure, the chassis structure, the supporting structure, the hydraulic adjusting structure and the suspension arm structure are integrated into a whole, and the chassis structure achieves flexible movement and stable gravity center through an extension rod, a cross rod and rollers at the bottoms of the four corners. The symmetrically-distributed connecting rods and the auxiliary supporting rods form a triangular supporting frame, lateral torque generated by eccentric loads is counteracted, the hydraulic adjusting structure drives a suspension arm rod sleeve to rotate through a hydraulic cylinder, a hydraulic rocker and a four-connecting-rod mechanism, and precise adjustment of the lifting height and angle is achieved in cooperation with a plug pin type extending suspension arm. The lifting hook structure integrates the anti-falling pressing rod and the reset spring, materials are prevented from falling off accidentally, through a multi-fulcrum mechanical balance system, hydraulic dynamic adjustment and safety protection design, the stability, flexibility and safety in the lifting process are remarkably improved, and the material carrying requirement under the complex working condition can be met.
