Double-girder bridge crane

largelightweight

The retrieval device adopts a fork arm structure, which can effectively achieve fast retrieval and placement of items through the joint action of various operating mechanisms, improving work efficiency. 2. Adopting a three in one drive mechanism, C-wheel structure, modular assembly, and ensuring the installation accuracy of each mechanism by processing the bridge as a whole. 3. Adopting a rigid anti shake telescopic arm device to ensure fast and accurate retrieval and positioning. 4. Adopting a double-layer trolley structure, the upper trolley is a rotating trolley that can lift materials in all directions within a 360 ° range, adapting to multi angle lifting. 5. The small car has been equipped with an anti rollover hook device, making the crane safer and more reliable, and preventing all safety hazards from occurring. 6. The running mechanism of the large and small vehicles has added a horizontal wheel set, which overcomes the misalignment of the liquid sand mold caused by the running impact, ensures the good molding of the castings, and improves the product quality of transporting materials. 7. Adopting a circular drag chain power supply device reduces the overall height of the machine and lowers the cost of the factory building. 8. The bridge adopts a lightweight design concept and finite element analysis technology. Based on the characteristics of the materials, the structural parameters are designed reasonably to ensure the reliability of product quality.
