Push block assembly with shear load transmitting means

摘要

A construction vehicle has a push-pull arrangement mounted on a forward end of the frame thereof. Such arrangement comprises a detachable bail pivotally mounted on the frame and adapted for engagement with a hook of another vehicle and a detachable push block assembly detachably mounted on the frame. A common bore is formed in the frame and push block assembly to mount a like-shaped annular member for transmitting shear loads imposed on the push block assembly to the frame directly.
