Loading trolleys for meat products

The innovation concerns a loading trolley for the transport of meat products, which is a box trolley made of stainless steel is formed and has a square jacket with a bottom which is reinforced by a sub-floor on which the bearing blocks for the rollers are attached.

In the manufacture of this well-known loading trolley the box-shaped jacket is placed on the deep-drawn base and welded to it. In order to obtain a perfect weld seam, the jacket and bottom must be exactly butted. Adherence to the exact dimensions when pre-fabricating the jacket and floor, which is necessary for the two to be assembled properly Parts are required presents considerable difficulties.

Due to hygiene regulations, all weld seams must of the loading trolley can be processed cleanly so that no meat residues can get stuck in the box container. this means that in the lower area of the box jacket all around running bottom weld and the jacket weld from the inside and outside arranged perpendicular to the box bottom and the circumferential The weld seam of the underbody must be sanded smooth from the outside. This labor-intensive welding and grinding work require a considerable expense, which is reflected in the manufacturing price of the loading trolley is reflected.

It also arises during the manufacture of the loading trolley occasionally scrap in that the stainless steel sheet is grinded through when grinding the welds smooth.

Finally, there is the stability of the loading trolley due to the bottom weld seam in the lower jacket area so reduced that especially with shock loads during operation and also with heavy fillings there is a risk that the jacket bursts in the area of the bottom weld.

The innovation is based on the task of a loading trolley to create, which is compared to the known constructions by significantly cheaper manufacturing costs and is characterized by greater strength.

Starting from a loading trolley of the type described above Art this object is achieved according to the invention in that the one-piece sheet metal blank with rounded sharp incisions in the lower extension of the four bending edges bent jacket a bent into the ground plane, has circumferential edge which limits an insertion opening for the welded-in bottom that the jacket is inside of a jacket section straight and in the corner joints of the bottom edge Forms arcuate abutting edges, which are welded together, and that under the box bottom at the bottom edge Reinforcement bottom is welded, which covers the outer bottom weld seams.

Another feature of the innovation are the visible welds, namely the inner and outer jacket weld, the inner and outer circumferential welds in the corner joints of the bottom edge of the jacket, d ~> Internal weld of the insert base and the external weld of the reinforcement base smooth slept.

The new charging trolley for meat products stands out compared to the loading trolleys on the market by a greater stability, which is due to the edge of the container shell bent into the bottom plane and the Arrangement of the bottom weld seam is achieved in the ground plane,

as well as a cheaper manufacture, -v through the cover of the bottom weld seam by the reinforcement bottom and the resulting saving of the ski egg colors tsganges for äuße-; yields i re bottom weld. "[

The rectangular, one-piece sheet metal blank 10 according to FIG. 3 for the jacket 2 is in the lower extension of the four bending edges 11, 12, 13, 14 with rounded pointed incisions 15 | Mistake.

19a, 19b and in the corner joints 20, 21, 22, 23 of the bottom edge arcuate abutting edges 24a, 24b, which are each welded to one another.

The reinforcement base 4 welded to the base edge 17 covers the outer base weld seam 25 so that it is not smooth must be sanded. The other visible welds of the loading carriage 1, namely the inner and outer Shell weld seam 26, 27, the inner and outer round weld seam 28, 29 at the corner joints 20-23 of the bottom edge 17 and the Inner weld seam 30 of insert base 3 is ground smooth.

To increase the stability and to avoid the risk of injury, the jacket 2 has a flanged edge 31 on. A handle 32 welded to the front wall 2c is used to push and pull the cart.

The side rollers 8, 9 have a larger diameter than the front and rear rollers 6, 7 to to give the loading trolley a slight rotation.
