Abstract:

A self-aligning and end fixity connector for connecting a hydraulic cylinder piston rod to its respective section in a multi-section telescopic boom assembly wherein a pair of rectangular plates are secured to the free end of the piston rod, the plates being received in retainers secured to the boom section to thereby prevent the piston rod from rotating and thus providing end fixity to the rod. A clearance is provided between the plates and the retainers to allow a slight floating action of the rod in a vertical plane so that the rod connection point is substantially in alignment with the cylinder connection point to allow full retraction without binding of the boom sections.
