The beneficial effect of the application is：

The crane of the application can under no electric power environmental or mustn't use electrical equipment explosion-proof environment under use, It is novel reliable；Because the cantilever beam of the application is arranged at below girder, and running trolley can be run back and forth above girder, So the crane of the application not only can with the next door workshop goods of unloading cart traffic direction end points, and can unloading it is big The goods in car running track line side workshop；Pulling crane gear (200) includes various cucurbits, and it is lifted or decentralization goods relies on The pulling function for pulling chain (201) is operated；And crane gear is made along cantilever beam rail by slant handle zip strip (201) Road moves back and forth to be rotated with cantilever beam；Whole crane edge can be driven by pulling the chain (84) in cart running gear by pulling Train track to run back and forth；It can be run by above-mentioned integrated motion, such as cart, cantilever beam rotates, and pulls crane gear fortune It is dynamic, running trolley motion, just can object by pull driving from outdoors or the handling of next door workshop to workshop domestic demand will place, Carry out to borrow the transhipment of other transporting equipments outdoors with the next door workshop of workshop surrounding or workshop during goods handing-over, it is convenient Operation, it is cost-effective to reduce equipment.

In the case where manually pulling chain (710) effect, running trolley can be run running trolley along girder both ends in the application, It is adapted to large span workshop operation；Chain drive, stable non-slip efficiency high.

The chain drive of trolley travelling sets two sets of roller chains in the application, can also with a set of roller chain but Not as two sets of stabilizations；Strainer (74) in chain drive is provided with two studs (741) and bearing is threadedly coupled, and two Individual stud position is stable, and sprocket wheel is not overturn；The elastic of chain can be adjusted by the nut in regulation stud；Bracket under chain It is avoided that chain is seriously sagging.

Track above the application middle girder uses inverted " u "-shaped track, and the wheel of running trolley is bushing to be run in orbit, This spline structure can effectively play anti-roll-over action to running trolley.

After the application cantilever member and suspension rod axis connection, then connected with suspension rod axle thread by stop nut, and have bolt (99) connected through the diameter of stop nut and suspension rod axle, avoid stop nut from loosening, securely and reliably, on stop nut Blind hole can facilitate lever to insert, and it is light to pull nut, easy disassembly and maintenance.

Bearing block and suspension rod axis connection in the application rotating mechanism bear lifting power by thrust bearing, and suspension rod axle is by bearing The spacing firmly radial positions of A and above and below bearing B, ensure that suspension rod axle can bear very big axial force and not offset radially, so as to ensure Drive device axiality is good, and hinged cantilever component is laborsaving.
