Revolute pair between described shifting axle and the slide block, the moving sets between slide block and the sliding guide groove can compensate in the upper trolley frame moving process vibration on short transverse and displacement.
Between described upper trolley frame and the upper strata track, the sliding roller assembling of load-carrying is installed, has reduced the running resistance of upper trolley frame, compressed the size of whole double-layer trolley in short transverse.
Compared with prior art, the utility model has the advantages that conspicuously, mainly show:
1, increase the work area of suspension hook group:
2, compact conformation, overall dimension is less;
3, whole dolly weight is lighter, saves cost;
4, this equipment satisfied hoisting crane under particular job environment to the requirement of work area, reduced energy consumption.
