Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1, this utility model provides a kind of technical scheme: a kind of large span crane is adjustable by anti-deflection four-way
Formula horizontal wheels, including horizontal wheels 12, is socketed with bearing 9 in horizontal wheels 12, be full of grease in bearing 9, and the middle part of bearing 9 is provided with
