The beneficial effect of the application is as described below：

Cantilever beam in the application crane can be stretched out between crane locomotive to directly lifting goods outdoors or to next door workshop Thing；The next door workshop goods of cart traffic direction end points can be not only lifted by crane, and cart running track line side can be lifted by crane The goods in workshop；Because the cantilever beam of the application is arranged at below dolly and girder, cantilever beam can be by stretching into below support rail beam The direct lifting cargo in next door workshop, or the workshop operation outdoors of cart traffic direction can be directly stretched out, because the generally door in workshop Top can reach height where the support rail beam in this workshop substantially, therefore present techniques feature can realize the application purpose；Lifting After goods, pass through motion of the electric block along cantilever beam, or the rotation by cantilever member, or the shifting for passing through underslung trolley It is dynamic, or the motion by crane travelling mechanism, or by foregoing four integrated motion, the goods of lifting can be hung The place needed to this workshop；It can need not be borrowed when carrying out goods handing-over outdoors with the next door workshop of workshop surrounding or workshop The transhipment of its transporting equipment, improve efficiency.

Dolly i-beam track (21) is set below the girder in the application crane, and underslung trolley is suspended on girder track On, its installing space position is reduced, is particularly suitable for roofing with crane apart from small workshop.

Horizontal wheel apparatus in the application crane is arranged on two of end carriage, it is ensured that and rail is not gnawed in crane operation, It is especially suitable for large span crane；Horizontal wheels in horizontal wheel apparatus carry wheel rim, can serve " safety hook ", may be because outstanding Arm load beam is overweight, and for crane end carriage while upwarping, now the wheel rim of horizontal wheels catches on running track, avoids crane from tumbling, Ensure safety；Can be rotated in the same old way while horizontal wheels catch on track, crane can run advance in the same old way, this technology use than The safety hook of steel plate type is advanced, and stuck phenomenon does not occur for cart operation.

End carriage in the application crane connected using two balance beams (102) and a middle connecting rod (101) and Into, it is such to combine the supporting multigroup wheel of end carriage, the wheel group of small-wheel-diameter can be used, makes the sectional dimension of end carriage small, is configured to This is low, and can solve the problems, such as the small wheel load of crane large-tonnage.

It is simple in construction in cart actuating device (8) in the application crane, in light weight, most of accessory in drive device Can purchased parts, price is low；The gear teeth of varying number can be set on the wheel rim of wheel, the reductor output gear with standard can group Into different fast ratios, the different speed of service demands of user can be met.

Underslung trolley (3) in the application can move back and forth along girder both ends, be suitable for big width workshop and use；Suspension Drive mechanism (34) on dolly can be in whole set procurement standarized component on the market, supporting facility；Wheel connection in drive mechanism On the edge of track (21) both sides Ji, ensure that underslung trolley does not drop, so as to ensure that crane is safe to use；Pacify underslung trolley side Fill two sets of drive mechanisms to be connected on same track, and roller devices (35), its benefit are installed beside every set drive mechanism Be to avoid single driving be possible to because dolly somewhat upwarp on one side adhesion wheel not rail and caused by can't run phenomenon, double drives It is dynamic to ensure that trolley travelling is smooth；Roller devices can limit underslung trolley while the degree upwarped, ensures that underslung trolley is stable, operation It is smooth；Elongated hole is provided with bearing side panel in roller devices in the horizontal direction to install with roller shaft, its benefit is easy for roller Dismounting maintenance；When the bearing damage in roller devices, roller and its roller shaft can be taken off repairing from bearing horizontal direction, operation It is convenient；Power supply needed for underslung trolley and electric block and rotating mechanism passes through the lashed cable (123) on dolly lashed cable device (124) Power supply can be run back and forth with underslung trolley.

Bearing block and suspension rod axis connection in the application rotating mechanism bear gravity by thrust bearing, and thrust bearing is arranged on Bearing block top, it is easy to dismount；The inner hole structure of bearing block is simply easy to process；Sleeve (43) is that high-abrasive material makees sliding bearing Use, reduce the fit clearance of suspension rod axle, increase rotational stabilization, increase the axiality of drive mechanism, cantilever member, which rotates, to be saved Power；Stop nut A band dust covers (441) give bearing proofing dust and protecting, while can seal the butter in bearing；Stop nut A is with hanging After bar axis connection, then the connection by bolt (46), anti-loose effect is played, ensures rotating mechanism safety；Drive in rotating mechanism Dynamic device output shaft is increased degree of flexibility, improved between drive device and suspension rod axle by shaft coupling (48) and suspension rod axis connection Malalignment regulating power.

Cantilever beam in the application, which is provided at both ends with buffing pad, can avoid electric block from moving back and forth impact along cantilever beam Or overtravel；After stop nut B in cantilever member connection connects with suspension rod axle thread, then to have locking plate (110) to be connected to anti- Loose nut B is with suspension rod axle spindle-end looseness-proof breach, avoiding stop nut B from unclamping, securely and reliably.
