Abstract

Improvements in the end-fixing and self-aligning connectors, to connect a hydraulic cylinder piston rod to its respective section, in a multi-section telescopic boom assembly, and whose connector comprises: a hydraulic cylinder, mounted within a section of a set of gable formed by several sections; means for connecting said cylinder to said section; a piston rod, slidably mounted on said cylinder; a piston on one end of said stem, located within said cylinder; and means for fixedly connecting the free end of said piston rod to another action of said boom assembly formed by various sections, said rod connector means including other retention means in housings or cavities, the free end receiving, correspondingly configured of the piston rod to prevent rotation of the piston rod about a horizontal transverse axis, while allowing a floating action of the piston rod in a vertical plane, bringing the connection points of the cylinder and piston to their respective boom sections, stay in alignment with each other.
