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 suspension end carriage dolly and girder, cantilever beam can pass through support rail beam
The direct lifting cargo in next door workshop is stretched into lower section, or can directly stretch out the workshop operation outdoors of cart traffic direction, because generally
The door top in workshop can reach height where the support rail beam in this workshop substantially, therefore present techniques feature can realize the application mesh
's；After lifting goods, by motion of the electric block along cantilever beam, or the rotation by cantilever member, or pass through suspended end
The movement of beam dolly, or the motion by crane travelling mechanism, or by foregoing four integrated motion, can be lifting
Goods hang onto this workshop needs place；Can when carrying out goods handing-over outdoors with the next door workshop of workshop surrounding or workshop

The driving wheel in suspension end carriage dolly (3) drive mechanism in the application is enclosed on the edge of track (21) both sides Ji, is protected
Card dolly does not drop, so as to ensure that crane is safe to use；A pair of driving wheels are all driven by motor, and the driving force of operation is big, are passed
It is good to pass power effect；Hang and two sets of drive mechanisms are set on end carriage, being advantageous in that can avoid single driving from being possible to because of dolly on one side
Somewhat upwarp adhesion wheel not rail and it is caused can't run phenomenon, dual drive ensures that trolley travelling is smooth；Hang end carriage dolly
It can be moved back and forth along girder both ends, be suitable for big width workshop and use；Hang end carriage dolly and electric block and whirler
Power supply needed for structure by lashed cable (123) along choose led on electric frame cable rail (124) can with suspension end carriage dolly run power supply back and forth.
Drive mechanism is arranged on inside suspension end carriage in the application, and suspension end carriage is overall high when being connected with the track under girder
Spend small, so entirely suspension end carriage dolly swings small, stablizes；Car bumper (211) on girder track can simultaneously be kept off equipped with buffer
The suspension end carriage dolly firmly run, ensure car safety.
Have the gear auxiliary driving of a pair of elevating arcs transmission in rotating mechanism in the application crane, by big elevating arc,
The different numbers of teeth setting of small elevating arc, can meet precise requirements of the user to the cantilever beam rotary speed of crane, avoid directly
Selection standard reductor it is general speed than and caused cantilever beam rotating speed and the larger error of actual demand；Passed using elevating arc
It is dynamic, the drive device in rotating mechanism can be made to use horizontal speed-reducer, reduce setting height(from bottom).
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.
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；Rotary limit device (58) is provided between cantilever member and running trolley, cantilever beam can be avoided excessively to rotate, i.e., not
The rotation of more than 360 degree angles, prevent from being pulled on Holder for hanging household utensiles (52) that the cable (6) of electric block is wrapped in cantilever member
It is disconnected because the cable (6) of electric block be draw from the junction box on running trolley it is ensuing；Safety ruler is welded on cantilever member
Holder for hanging household utensiles on benefit be that safety ruler can rotate with cantilever member, and travel switch be fixed under running trolley it is relatively motionless,
Its cable is passed directly to be placed on the control cabinet on running trolley, and travel switch connection is not easy failure；Cantilever member connects with suspension rod axle
After connecing, after positioning is connected with suspension rod axle thread by stop nut B, then with bolt (99) through stop nut B and suspension rod axle
Diameter connects, and avoids stop nut B from loosening, securely and reliably.
