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, novelty can Lean on；Because the cantilever beam of the application is arranged at below girder, cantilever beam can be directly stretched out between crane locomotive to outdoors or to next door Workshop directly lifts goods；The lifting or decentralization goods for pulling ring-chain hoist (200) are made by the pulling for pulling chain (201) With being operated；By drawing, dragging or slant handle zip strip (201) or pull steel cable on ring-chain hoist suspension hook, make coaster (6) Along cantilever beam transverse movement；By in oblique pull hand draw ring chain block pull chain (201) can make cantilever beam rotate and can appoint Meaning angle rotates；By pull the chain (84) that pulls in cart running gear can drive whole crane along train track back and forth Operation；It can be run by above-mentioned integrated motion, such as cart, cantilever beam rotates, coaster motion, ring-chain hoist hook lifting, Running trolley move, just can object by pull driving from outdoors or the handling of next door workshop to workshop domestic demand will place, with car Between surrounding next door workshop or workshop can need not borrow the transhipments of other transporting equipments when carrying out goods handing-over outdoors, convenient working, It is cost-effective to reduce equipment investment.

In the case where manually pulling chain (710) effect, running trolley can be run running trolley along girder both ends in the application, be 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 be with a set of roller chain but not as two Set is stable；Strainer (74) in chain drive is provided with two studs (741) and bearing is threadedly coupled, two spiral shells Post 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 can be kept away It is seriously sagging to exempt from chain；A pair of large and small gear drives are set in chain drive, decelerating effect is played, pulling force can be mitigated, especially It is adapted to the big running trolley of tonnage.

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

Cantilever beam one end, which is hung, in the application pulls ring-chain hoist (200) handling weight, other end hanging balancing weight (9), and two Person's weight offsets, and can reduce the tilting moment of crane, improves lifting capacity, while increase crane stability and security.

Left lever, right pull bar and cantilever beam and Holder for hanging household utensiles composition triangular structure in the application cantilever member, make cantilever member firm The advantages that degree is strong, stability is good, load-carrying is big；Cantilever beam is made using C-shaped channel steel, it is in light weight, few with material；Carried on coaster Rolling bearing, rotate flexibly, and it is simple in construction, cost is low.

Bearing block and suspension rod axis connection in the application rotating mechanism bear lifting power by thrust bearing, and thrust bearing is arranged on bearing Seat top, is easy to dismounting to safeguard；The inner hole structure of bearing block is simply easy to process；Sleeve (43) is that high-abrasive material makees sliding axle Use is held, reduces the fit clearance of suspension rod axle, increases rotational stabilization and axiality, cantilever member rotates laborsaving；Stop nut Band dust cover (441) gives thrust bearing proofing dust and protecting, while can seal the butter in thrust bearing；Stop nut and suspension rod axis connection Afterwards, then the connection by bolt (46), anti-loose effect is played, ensures rotating mechanism safety.
