The beneficial effect of the application is as described below：

The suspension hook on lifting truck (01) in the application can be usually used in this either inside cargo hoisting, because lifting cargo Center of gravity do not produce tilting moment in the underface of crane, crane and lifting truck, equipment operates steadily, can use at a high speed Operating mode is spent to improve efficiency, and available for lifting large-tonnage object；Lifting truck is acted on available for main lifting.

Cantilever beam in the application running trolley (3) can be stretched out between crane locomotive to directly hanging outdoors or to next door workshop Loading thing；The next door workshop cargo of cart traffic direction endpoint can be not only lifted by crane, and cart running track line can be lifted by crane The cargo in side workshop；Since the cantilever beam of the application is arranged at below trolley and girder, cantilever beam can be by below support rail beam The direct lifting cargo in next door workshop is stretched into, or can directly stretch out the workshop operation outdoors of cart traffic direction, therefore the application skill Art feature can realize the application purpose；After lifting cargo, by movement of the electric block along cantilever beam, or pass through cantilever structure The rotation of part, or the movement by running trolley, or the movement by crane, or by foregoing four integrated motion, The cargo of lifting can be hung onto the place of this workshop needs；Can when carrying out cargo handing-over outdoors with next door workshop or workshop The transhipment of other transporting equipments need not be borrowed, improves efficiency.

The suspension hook on lifting truck (01) in the application crane and electric block (10) suspension hook on running trolley (3) With the use of handling elongate article can be facilitated.

Electric frame (121) of choosing on the application loading bridge is equipped with two groups of moveable lashed cables (123), one group of connection lifting Trolley (01) is powered, another group of connection running trolley (3) power supply.

The cantilever crane of the application be suitable for workshop only have set up on the metope column of one side bracket be laid with track, another side Use the environment of workshop track；Cart actuating device is run on column track on end carriage in crane semi portal, on ground beam Cart actuating device run in the track of workshop.

Running trolley (3) in the application can be moved back and forth in the top of girder along girder both ends, be suitable for greatly across Workshop is spent to use；Running trolley both sides set safety hook (33) that cantilever beam can be avoided to overload and produce running trolley and upwarp, and ensure Running trolley catches on girder siding track and does not drop, so as to ensure that crane is safe to use；Running trolley sets two sets of trolleies to drive Device (32), can avoid single driving be possible to because trolley somewhat upwarp adhesion wheel not produce can't run phenomenon rail, protect It is smooth to demonstrate,prove trolley travelling；Two adhesion wheel groups in the application drive car pass through spline box coupling (325) Connected with floating axle, spline housing is simple in structure, the small handling ease of size, low from heavy and light cost, wherein using floating axle and Spline housing, which coordinates, makes the not parallel error compensation of axis good.

The safety hook (33) installed on running trolley in the application, by T-shaped hook seat and L-shaped hook body be bolted and Into this spline structure is convenient to be adjusted；T-shaped hooks the vertical direction slot hole (3322) with horizontal slot hole (3312) and L-shaped hook on seat Mutually adjust, make that front and rear up and down gap can be adjusted between eave tile and siding track；Hold during in-site installation with the siding track on girder Easily adjust most suitable gap connection, it is allowed to which larger manufacture mismachining tolerance, scene can install.

Anti- tipple in the application crane is installed on the both ends of end carriage, and wheel on end carriage is limited in by horizontal wheels Orbit centre is run, it is ensured that rail is not gnawed in crane operation；One of the advantages of this anti-tipple horizontal wheels are installed on engineer room (631) in, wheel shaft (62) both ends are all fixed in the through hole (632) of engineer room, and cantilever, wheel shaft can not bear big such horizontal wheels Lateral impact forces not flexural deformation；Horizontal wheels in anti-tipple carry wheel rim, can serve " safety hook ", may be because outstanding Arm load beam is overweight, and for crane end carriage while upwarping, the wheel rim of horizontal wheels catches on running track at this time, 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；Since ground beam length is longer than end carriage, so being set on end carriage Put anti-tipple.

End carriage and ground beam both ends in the application crane all set cart actuating device, ensure that cart operation is smooth, keep away Because end carriage or ground beam may upwarp when exempting from unilateral driving, driving wheel not rail produce idle running phenomenon；The cart driving dress of the application (8) structure novelty is put, it is highly practical；The wheel body of connecting shaft wheel is once swaged into wheel shaft, simple in structure, is especially suitable for path car Wheel, it is that can stand very big axial float inner flange seat all without de- that the ring flange of inner flange seat, which is connected to benefit on the inside of end carriage, Off normal and put, the connection bolt of inner flange seat need not bear big axial tension, and wheel alignment is good；The output shaft of decelerating motor can To be flat key axis or splined shaft or double bond axis, according to torque different situations, rationally coordinate with wheel axis hole；Decelerating motor leads to Cross cushion pad to be connected on end carriage or ground beam, due to the cushioning effect of cushion pad, alleviate decelerating motor and start, brake to produce and rush Vibration is hit, protects driving device.

Bearing block and sunpender axis connection in the application rotating mechanism bear gravity by thrust bearing, and thrust bearing is installed on Bearing block top, it is easy to disassemble；The inner hole structure of bearing block is simply easy to process；Sleeve (43) makees sliding bearing for wear-resistant material Use, reduce the fit clearance of sunpender axis, increase rotational stabilization, increase the concentricity of driving 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, is improved between driving device and sunpender axis by shaft coupling (48) and sunpender axis connection Malalignment regulating power.

Rotary limit device (58) is equipped between cantilever member and running trolley in the application, cantilever beam can be avoided excessive Rotation, i.e. no more than 360 degree angle rotations, prevent the cable (200) of electric block to be wrapped in the Holder for hanging household utensiles in cantilever member (52) be torn on because the cable (200) of electric block be draw from the junction box on running trolley it is ensuing；Cantilever structure After part and sunpender axis connection, connect by stop nut with sunpender axle thread after positioning, then stop nut is passed through with bolt (99) Connected with the diameter of sunpender axis, avoid stop nut from loosening, securely and reliably.
