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, 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 (7) rely on the drawing for pulling chain (71) Action is with being operated；By drawing, dragging or slant handle zip strip (71) or pull steel cable on ring-chain hoist suspension hook, make coaster (9) along cantilever beam transverse movement；Can be with by the chain (71) that pulls drawn in drawstring (58) or oblique pull hand draw ring chain block Make cantilever beam rotate and can random angle rotation；By pulling the endless chain (84) pulled in cart running gear that whole can be driven to rise Heavy-duty machine is run back and forth along train track；It can be run by above-mentioned integrated motion, such as cart, cantilever beam rotates, coaster motion, Ring-chain hoist hook lifting, just can be local from handling outdoors to workshop domestic demand by pulling driving object, with workshop foreign goods Thing can need not borrow other hoisting facilities when joining；Coaster is the conventional accessory for hanging Transport Machinery industry, easily buying.

The crane of the application be suitable for workshop only have set up on the metope column of one side bracket laying track, another side use The environment of workshop track；Wheel is run 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 main on the speed ratio and grade beam of driving wheel B and gear shaft (85) on end carriage in cart running gear (8) The big sprocket wheel (811) of driving wheel A connections is more identical than being designed to the speed of minor sprocket (89), is so manually pulling endless chain (84) When, so that it may bangle wheel (83) rotation is drive, so as to drive driving wheel A, the operation of driving wheel B synchronous same-speeds；If unnecessary Human hand, can also boosting supporting rack operation, reduce the pulling force for pulling endless chain, crane operation is convenient.

The Liang Tai (3) of this crane is fixed on motionless on girder, is suitable for narrow workshop, with next door workshop or workshop Carry out to borrow the transhipment of other crane gears outdoors during goods handing-over, improve efficiency, it is cost-effective to reduce equipment investment.

Brace and cantilever beam and Holder for hanging household utensiles composition triangular structure in the application cantilever member, make cantilever member rigidity By force, the advantages that stability is good, load-carrying is big；Cantilever beam is made using C-shaped channel steel, it is in light weight, few with material；The axis of rolling is carried on coaster Hold, 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 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 Suspension rod axle axiality is good, and hinged cantilever component is laborsaving.

After the application cantilever member and suspension rod axis connection, then connect with suspension rod axle thread by stop nut, and by stopping Moving plate and suspension rod axis connection, avoid stop nut from loosening, securely and reliably.
