Double Girder Bridge Crane

Bridge crane is horizontal plane in workshops, warehouses and yard rigger materials over the lifting equipment. Due to the ends of the bridge is located in tall cement posts or metal stents, shape like bridge. Bridge crane along the bridge on both sides laying in the orbit of an elevated operation, can make full use of the longitudinal girder hoisting the space below materials, not to suffer ground equipment obstacles. It is to use the widest range, the largest number of a kind of hoisting machinery.

New QD electromotive double beam crane is "QD" upgraded products, it is a kind of structure more reasonable, assembling, intelligent crane is superior. Lifting weight for guide = 5-10.5 500T, span 35m, job level for - A3, A5, A6, A7. Working environment temperature + 40 °C below, high temperature indicating. Undertake special non-standard design.
