ABSTRACT:
An alignment device on a crane boom having telescopic boom sections and a side stowable boom extension swingable from a stowed position to a working position and connectable to a nose assembly on a boom section by upper and lower clevis connections on each side of the nose assembly. The alignment device includes an abutment assembly mounted on the nose assembly boom section, and another abutment assembly mounted on another boom section. The abutment assemblies engage each other during relative retracting movement of the boom sections and forcibly engage the end of the boom extension to align the apertures of the clevis connection and nose assembly to facilitate the insertion of the pin therein.
