| 20110198912 | MOBILE BASE FOR REDUCING LATERAL PRESSURE OF THE BODY LIFT CYLINDER OF A DUMP BODY - Disclosed is an equipment of the type comprising a frame on which is mounted a dump body liftable by means of a body lift cylinder having two opposite ends, a first one of these ends being connected to the frame and the other one to the dump body in order to lift it up when the cylinder is extended. This equipment is characterized in that the first end of the cylinder connected to the frame is mounted on a mobile base which is fixed onto the frame in such a manner as to have some liberty of 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. | 08-18-2011 |
