System for Controlled Tipping of a Dump Body in a Transport Vehicle

Abstract

A system (1) for controlled tipping of a dump body (2) of a transport vehicle (3), wherein the vehicle (3) comprises a support frame (4), a counter frame (5) with a pair of parallel cross members (6, 7), a lift cylinder (8) for lifting the dump body (2) and a locking device (15) for selectively locking the dump body (2). The locking device (15) comprises support means (15A, 15B, 15C, 15D) for supporting the dump body (2) which are designed to be selectively locked and are placed at the ends of said cross members (6, 7). Each of the support means (15A, 15B, 15C, 15D) comprises a convex element (16) having a spherical head (17), a concave element (18) having a seat (19) for the spherical head (17), a locking pin (20) for selectively locking the concave element (18) and the convex element (16) to prevent separation thereof, and a double-acting actuator (21) for imparting a two-way motion to the pin (20). Each convex element (16) is secured to a bottom face (2′) of the dump body (2) and each concave element (18) is fixed to said counter frame (5) in alignment with a respective convex element (16). Each actuator (21) is housed in a recess (11, 12) of a respective cross member (6, 7) for actuating a respective pin (20) along a respective transverse direction (X) and cause the convex element (16) and the concave element (18) to be locked together to protect each actuator (21) from possible impacts and damages.
