Abstract: Tail-gate operating and locking apparatus for tail-gates utilized in refuse handling vehicles. The apparatus includes hydraulically operated means with a piston rod pivotally connected to the tail-gate and a cylinder pivotally connected to a latch mechanism for locking the tail-gate on the vehicle body. The latch mechanism comprises a bell-crank pivotally connected to the hydraulic cylinder and a locking element pivotally connected to the bell-crank and having a latching pin adapted to engage a hook secured to the tail-gate in a closed position thereof. A ramp element is rigidly attached to the vehicle body. The ramp element is provided with a cam surface to guide the latching pin during its reciprocating movement from and into engagement with the hook.
