Suomi-Finland (FI) (5U) Multifunctional wagon body - Universalt vagnsunderrede

The invention relates to a tractor trailer or, alternatively, to a truck platform which can be used for lifting, moving and tipping interchangeable pallets.

From the previously known equivalents, the so-called some of the "forklift container wagons" are massive with two, three with platform bodies, leaving a small load capacity. Some lift the container diagonally, others do not tip over. Some put a heavy load on the rear axle of the tractor and some leave a lot of empty space between the frame and the container. Only a few wagons are able to carry multiple containers on top of each other.

None of the known "fork container trailers" as well as conventional trailers will be able to keep the tipping axle horizontal if the container is tipped when driving downhill horizontally.

Of the single-body wagons, the wagon according to SE 390 806 lifts the ground and transports the container on the same principle as the wagon presented by the invention. When moving from transport to container tipping, the trolley according to SE 390 806 has to be lowered between the container to the ground in order to grip the container with separate pins protruding from the paw parts in order to perform the tipping step. In the tipping phase, the container is loaded very heavily because there is support only at one end of the container. Tipping while the trolley is moving is thus very limited, even almost impossible depending on the terrain and driving speed.

In the design of the carriage according to the invention, it has been possible to avoid all e.m. deficiencies, and the wagon is characterized by what is described in your claim.

In the detailed description of the carriage, reference is made to the drawings, in which Fig. (1) shows the carriage in an axonometric view. Figures 2,3,4 show the side projections of the trolley: figure (2) the initial situation of lifting, figure (3) the transport position, figure (4) the final stage of tipping.

The trailer is attached to the tractor by means of the towing eye (1). The body itself consists of three parts: the front body (2), the rear body (3) and the paws (4). The parts are nested together and the force holding the parts together, guiding the frame, is obtained from the hydraulic cylinders (5) and (6). The cylinders (5) are connected to operate synchronously, while the cylinders (6) operate independently of each other. The trolley moves on wheels (8). The transport platform is supported on the rear frame (3) by support pads (9).

The operation of the trolley is as follows (Figures 1-4):

The container rests on the ground. The tractor reverses the wagon around the container. The cylinders protrude from their inner position, whereby the support tabs (9) lift the supports from the bottom of the container. The operation of the cylinders is controlled from the tractor by adjusting the flow of valves located either in the cab or in the car body, so that the angle of inclination of the carriage is desired in both the longitudinal and transverse directions. With the transverse inclination adjustment, the trolley can be kept in a horizontal position regardless of the shape of the terrain. In the transport position, the cylinders are in operation, so that the hydraulic system balances the dynamic load peaks on the frame. In the top transport position, the trolley can be reversed on top of another container, thus stacking several containers on top of each other. The transport stage can be switched to tipping while the carriage is moving by adjusting the cylinders (5) to the pushing movement.

The two synchronously acting cylinders (5) attached to the side beams can be replaced by a telescopic cylinder located at the drawbar.
