30 meter bridge erecting machineworking principle

The bridge erecting machine consists of two parts, namely the beam transport and erection machine and the lower guide beam machine. The transport and erection beam machine is responsible for taking source beams from the beam making yard and lifting them to the bridge construction site, and cooperating with the lower guide beam machine to carry out bridge construction work. After the bridge construction is completed, the lower guide beam machine will automatically change the position of its support legs in order to proceed to the next cycle of operation. The wheelset of the bridge erecting machine can turn 90 degrees in place.

During the operation, the front and rear legs of the bridge erecting machine play a load-bearing role. The box girder is transported to the abdominal cavity of the gantry crane by a beam transport trolley, and the middle and front legs bear the load. The unloading crane of the rear leg lifts the beam transport trolley,Then use the longitudinal crane to make way for the space of the concrete box girder to be erected.

Set up six support points between the land and one pier of the bridge, and then transport the prefabricated beams from the prefabrication plant to the land and one pier of the bridge. Then, use a conveyor mechanism to place the beams between one pier and the second pier. Generally, several beams form a bridge deck, and once a bridge deck is erected, the gantry crane can be moved between one pier and the second pier to lay the next beam. The whole machine adopts walking and guiding through the hole, relying on the driving of the crane to move the support legs forward, without the need to configure longitudinal movement power of the support legs. The hydraulic motor drives the drum, and the whole machine moves horizontally. The control system of the machine is controlled by a programmable controller.
