The ends of the machinery carrying body form trucks housing support wheels for suspending the crane from overhead rails. The traversing system is disposed in the machinery body and consists of an air motor coupled to drive pinions which engage a gear rack on each overhead rail. The traversing systems and a pneumatically powered hose reel for holding an air hose for a pneumatically powered hoist are powered from a central air supply through a pneumatic control circuit.
