Problems solved by technology
[0004] When the roof crane is transferred through the second method above, it is necessary to arrange the motion guide rail and the travel motor mechanism of the roof crane in advance, which will directly lead to an increase in the cost of the roof crane. The beam is directly fixed on the roof surface. If the above-mentioned transition method of the guide rail is adopted, it will be very inconvenient to arrange the weight on the cross beam of the roof crane.
At the same time, this is less cost-effective for roof cranes with few transitions (for example, one time) on the top of the same floor

The invention relates to the technical field of engineering machinery, and discloses a traveling mechanism for a roof crane and the crane. The traveling mechanism comprises a wheel device and a traction device, the wheel device is arranged on a base of the crane, and the traction device is used for connecting the crane to a fixing point at a traveling destination of the crane. The crane can move towards the fixing point through the wheel device under the traction of the traction device. The traveling mechanism comprises the wheel device and the traction device, and the traction device can drag the crane to the fixing point at the traveling destination. Through the technical scheme, the traction device can be used for directly connecting the crane and the fixing point at the traveling destination, and therefore the crane is dragged to move towards the fixing point without guide rails and other auxiliary devices; not only is the structure simple, but also operation is convenient, and transfer of the crane can be quickly and conveniently achieved.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a traveling mechanism and a crane used for roof cranes. Background technique [0002] Roof cranes are mainly composed of lifting arms, balance arms, A-frames and other components. In the case of transition, usually other lifting equipment is used to disassemble the roof crane and then transfer each component to the designated position, and then reinstall the roof. The crane must be assembled for work. Therefore, every time the transition is completed, three steps are required: dismantling, transporting and erecting the tower. During operation, if there is no large-scale lifting equipment, it will be very difficult to disassemble and assemble the roof crane, and it will take a long time. [0003] In addition, the roof crane may also include a walking part for transitioning. The walking part is composed of walking motor mechanism, cross beam, guide rail and other c...
