Summary of the invention

The purpose of this utility model is in order to overcome above deficiency, a kind of reliable in quality to be provided, and is specious, the novel crane in bridge type hoisting crane that maintenance rate is low.

The purpose of this utility model is achieved through the following technical solutions: a kind of novel crane in bridge type, comprise the crane span structure assembly, the electrical equipment assembly, dolly assembly and traveling mechanism of the larger traveller, the left girder and the right girder that arrange about traveling mechanism of the larger traveller comprises, be provided with main driven end carriage at left girder, be provided with passive end carriage at right girder, two ends at main driven end carriage are connected with the adhesion wheel group, be connected with passive set of wheels at the two ends of passive end carriage, between main driven end carriage and passive end carriage, be connected by the end carriage tie-beam, left side in the adhesion wheel group is connected with extension pipe, left end at extension pipe is connected with energy disperser, all be provided with many group Solid wheel of vehicle in the both sides of adhesion wheel group and passive set of wheels, the dolly assembly comprises trolley frame, first operating unit, be provided with the walking platform in the both sides of trolley frame, being expert at walks on stage is provided with second operating unit, first operating unit and second operating unit all are by motor, retarder and drg are formed, first operating unit 9 also comprises suspension hook group 10, fixed pulley group 23 and steel rope 24, the motor of first operating unit is connected with Solid wheel of vehicle, and control by frequency converter, make the operation of hoisting crane milder, reduced greatly traditional operation and after impact situation and operating noise, wheel adopts Solid wheel of vehicle, increased its load-carrying ability, the different spans of each tonnage of girder of hoisting crane, all adopt same width from 10.5m ~ 40.5m, and the clapboard spacing of girder also adopts same size in the middle part, diamond plate on the walking platform, railing also adopts unified specification to make, thereby greatly reduces the cost of manufacture of production.

The utility model compared with prior art has the following advantages:

Compact conformation, volume is little, and is in light weight, and the dolly wheel load is even, and the cart wheel load reduces, safety more convenient to operate, reliable in quality, maintenance rate are low.
