A motor-driven garbage truck provided with a detachable garbage container equipped with releasable coupling elements, and also having permanently mounted thereon which includes a pouring chute in the forward portion, lifting and tipping apparatus for picking up a garbage can and discharging the contents thereof into the chute leading to a receiving space, and a conveying and compacting apparatus for transferring the garbage from the receiving space into the container through the receiving opening, which is provided with a closure is disclosed. The pouring unit is disposed in part above the driver's cab and in part between the cab and the container, the chute being disposed in a region extending behind and above the cab. The lifting and tipping apparatus includes at least one lifting arm, pivotally movable about a transverse pivot carried by the pouring unit or the chassis of the vehicle. The lifting arm carries at its free end a carrying rail, which is parallel to the tranverse pivot and pivotally movable between a pick-up position, in which the rail is disposed below and in front of the driver's cab, and a pouring position, in which the rail is disposed above and behind the cab. The rail is provided with a displaceable or pivotally movable, extensible coupling or gripping member for coupling to or gripping a garbage can placed on the street.
A motor-driven garbage truck having a chassis frame including front and rear axles and a driver's cab including a front windscreen mounted on said chassis frame and comprising a garbage container provided with a receiving opening and a closure member therefor and separable coupling elements, a pouring unit permanently mounted on said truck in a forward portion thereo and a pouring hute leading to a receiving space, lifting and tipping apparatus for picking up a garbage can and discharging the contents thereof into said chute, and a conveying and compacting apparatus for transferring garbage from said receiving space into said container through said receiving opening, said pouring unit being disposed in part above said driver's cab and in part between said driver's cab and said container, said chute being disposed in a region extending behind and above said driver's cab, said lifting and tipping apparatus comprising at least one lifting arm pivotally movable about a transverse pivot carried by said pouring unit or said chassis frame, said lifting arm carrying at its free end a carrying rail disposed parallel to said transverse pivot and which is pivotally movable between a pick-up position, in which said rail is disposed below and in front of said driver's cab, and a pouring position, in which said rail is disposed above and behind said driver's cab, said rail being provided with displaceable or pivotally movable extensible means for coupling to and gripping a garbage can, said displaceable or pivotally movable extensible means for coupling and gripping a garbage can including a link in the form of an arm, said link being eccentrically mounted on a profiled member slidably mounted on said carrying rail and extensible beyond at least one end of said carrying rail for pivotal movement about a vertical axis, the link at its free end carrying a triangular shaped self-centering claw member having beveled edges which cooperate with a similar shaped member on said garbage can for picking up said garbage can and means for pivotally moving said claw member between an outer position, in which said carrying rail or said profiled member picks up said garbage can and an inner position in which said lifting and tipping apparatus transports said garbage can to said pouring opening.
A tipping device for motor-driven garbage-collecting trucks comprising a holding claw adapted to cooperate with edge portions of garbage cans provided with open ends and upper sides and with a receiving pocket on the open ends thereof, and a gripping arm, said tipping device characterized by the fact that said holding claw is a plate having the shape of an isosceles triangle having an upwardly directed vertex and the upper sides of which form inwardly tapering, beveled gripping edges which cooperate with said receiving pocket on said garbage cans, said receiving pocket having a complementary undercut surface and being formed by a section member located on and reinforcing the edge portion of said garbage cans at an open end, said holding claw being attached to a free end of said gripping arm.
