Abstract
Crane bridge, esp. for heavy loads, such as foundry cranes, using two main bridge carriers connected by traverses; each carrier is located on one end (I) on a crane rail by a main balancer, whereas the other end (II) is located on the second crane rail by two auxiliary balancers to achieve three point mountings; and each carrier is fitted with a crab rail. The novelty is that the main balancer mountings are displaced by a dimension (a) outside the crab rails and in the direction of the crane buffers to prevent tilting, and ends (I) are joined by a wide traverse providing horizontal stiffness but some vertical flexure, whereas ends (II) are joined by a strap on pivot mountings. The crane bridge is extremely stable with high resistance to tilting, but some flexure is provided so the bridge will always sit securely on the rail track even if the rails are somewhat distorted.
