• D. Cantilever

Answer: (B)

The roller assembly that consists of a frame, wheels, and bearings is properly termed an end truck. End trucks are essential components in overhead crane systems, serving as the assemblies that allow the crane to move along its track. They typically include wheels designed to roll on the rail, and bearings facilitate smooth movement and reduce friction, enhancing the efficiency and safety of the lifting process. In the context of crane operation, an end truck is crucial because it supports the crane's trolley and enables horizontal movement across the structure. Understanding this component is vital for those working with cranes, as it directly impacts the system's function and stability.
