The beneficial effect of the application is：

The crane of the application can mustn't be used under without electric power environmental or under the explosion-proof environment using electrical equipment, It is novel reliable；Because the cantilever beam of the application is arranged at girder lower section, cantilever beam can be directly stretched out between crane locomotive to outdoors Or directly lift goods to next door workshop；The lifting or decentralization goods for pulling ring-chain hoist (200) is relied on and pulls chain (201) Pulling function is operated；By drawing, dragging or slant handle zip strip (201) or pull steel cable on ring-chain hoist suspension hook, cunning is made Car (6) is along cantilever beam transverse movement；Pulling chain (201) and rotate can cantilever beam in by oblique pull hand draw ring chain block And can random angle rotation；By pulling the chain (84) pulled in cart running gear whole crane can be driven along workshop rail Run back and forth in road；Can be rotated by above-mentioned integrated motion, such as cart operation, cantilever beam, coaster motion, ring-chain hoist suspension hook liter Drop, 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 outdoors that the transhipment of other transporting equipments can be borrowed when goods joins with the next door workshop or workshop of workshop surrounding, it is convenient Operation；Coaster is the conventional accessory for hanging Transport Machinery industry, easily buying.

The crane of the application be suitable for workshop only have on the metope column of one side set up bracket lay track, another side uses The environment of workshop track；Wheel runs on column track on end carriage in crane semi portal, and the wheel on grade beam is in workshop Run in track.

The application pulls the speed of drivewheel B and gear shaft (85) on end carriage in cart running gear (8) and compares and master on grade beam The big sprocket wheel (811) of driving wheel A connections is more identical than being designed to the speed of minor sprocket (89), so in artificial hand draw ring shape chain (84) When, so that it may bangle wheel (83) rotation is drive, so as to drive drivewheel A, the operation of drivewheel B synchronous same-speeds；If unnecessary Staff, it is also possible to which boosting supporting rack operation, reduces the pulling force for pulling endless chain, and crane operation is convenient.

The cantilever beam of the application crane also can reach next door workshop unloading goods from the middle of supporting rack.

Under artificial pulling chain (710) effect, running trolley can run running trolley along girder two ends in the application, Suitable large span workshop operation；Chain drive, stable non-slip efficiency high.

In the application trolley travelling chain drive arrange two sets of roller chains, it is also possible to a set of roller chain but Not as two sets stably；Strainer (74) in chain drive is provided with two studs (741) and bearing is threadedly coupled, and two Individual stud position is stablized, and sprocket wheel does 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；The transmission of one reductor (78) is set in chain drive, subtracting for not synchronized ratio can be selected Fast machine, can mitigate artificial pulling force, be especially suitable for the big running trolley of tonnage.

Track above the application middle girder adopts 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.

Brace in the application cantilever member and cantilever beam and Holder for hanging household utensiles composition triangular structure, make cantilever member rigidity By force, good stability, the advantages of load-carrying is big；Cantilever beam is made using C-shaped channel steel, it is lightweight, few with material；The axis of rolling is carried on coaster Hold, rotate flexible, and simple structure, low cost.

End carriage in the application crane arranges anti-tipple (11), and crane can be avoided to tumble, it is ensured that safety；When outstanding When arm beam may transship, end carriage is while upwarp, now the eave tile of L-shaped safety hook can catch on the upper cover plate Ji of cart support rail beam (12) Edge, it is to avoid crane is tumbled and ensures safety；Anti- tipple is connected with end carriage, in-site installation convenient construction；It is counter to tumble T-shaped on device hooks seat (111) and L-shaped safety hook (112) is designed with connecting elongated hole, in crane in-site installation, is easy to adjust Section relative position, easily installs in place；When upwarping occurs in crane end carriage, can be pulled by hinged cantilever component or movement Ring-chain hoist reduces lift heavy, can so change the position of centre of gravity of crane, it is ensured that stable, it is to avoid crane is tumbled.
