Patent ID: 8231178

Claim:
An equipment of the type comprising a frame on which is mounted a dump body liftable by means of a body lift cylinder located in the middle of the frame and having two opposite ends, a first one of said ends being connected to the frame and the other one of said ends connected to the dump body in order to lift the dump body up when the cylinder is extended, the first end of the cylinder connected to the frame is mounted on a mobile base fixed onto the frame to permit transversal inclination and thus to allow the cylinder to extend in a constant straight line even if a lateral torsion is applied onto the cylinder by the dump body when said dump body is lifted up, the mobile base having a support comprising a central part devised to receive and hold the first end of the cylinder, and two lateral parts that are opposite to each other and each in the form of a tubular shaft, said shafts being aligned on a common axis perpendicular to the cylinder; a set of two holding sleeves, each of said sleeves being provided with a cylindrical opening in which is inserted one of the shafts of the support in order to retain said support while allowing it to pivot about the common axis of said shafts, said holding sleeves being each provided with two opposite ends transverse to the common axis of the shafts, and two rigid holding pieces fixed to the frame of the equipment, said holding pieces being adapted and positioned as to receive and retain the opposite ends of each of the holding sleeves, while giving them enough liberty to allow the requested transversal pivotment required to allow the body lift cylinder to extend in a constant straight line even when it is subjected to a lateral torsion.
