Abstract

1. Refuse-collecting vehicle with a superstructure which comprises a refuse container (3) and a loading mechanism (4), which latter is fixed on the frame of a vehicle chassis, wherein at least those walls of the superstructure (2) which extend longitudinally of the refuse-collecting vehicle (1) respectively consist of two thin-walled wall elements (23, 24) held in spaced relation by spacer members (21, 25, 26, 26', 28, 29) and that the unobstructed spacing of the wall elements is a multiple of the thickness of a wall element.

Re: patent application and utility model auxiliary application "Compact garbage truck structure in super lightweight construction"

There have been numerous compact garbage trucks recently on the market and in use. The bodies of these refuse collection vehicles for household waste are made of sheet steel, angle iron, profile steels and steel Ar-Beits cylinders according to the current state of the art manufactured. As a result, these structures have a relatively high dead weight. So has a marketable Type with an empty weight of 12 7 $ 0 kg in the three-axle version a body weight of 56 (JO kg. The corresponding two-axle Type has an empty weight of 10 450 kg with a body weight of 5150 kg the payload 5550 kg. Since the compacted waste system compacts the waste extremely effectively, it often occurs in practice Axle loads that are not allowed to be exceeded. In the future it is to be expected that the household waste. is because the lightweight fabrics such as paper, cardboard, textiles, clothes, shoes, metal cans etc. are collected separately and fed back for recycling. This leads to even greater overshoots of the permissible total weight. The present invention aims through the super lightweight construction of the Building garbage trucks to remedy this problem and at the same time reduce costs in the fleet operation with 2-3 tons of payload achieve through rationalization and profitability. In this way, about one more load can be achieved per day per garbage truck and the profitability with the same carriage circulation be lifted. The present invention is based on the object, through the combination of components known per se, mechanical and hydraulic type to achieve the goal of super lightweight construction. There are several in the drawings

Exemplary embodiments of the subject matter _{: the} invention is shown schematically.

Show it ;

Fi gur 7 : A partial section of a piston-cylinder unit (working cylinder) in lightweight construction

A compressed waste collection container (2) with a capacity of 10 - 40 nr, for example, is installed on a standard chassis ^ 1). The outer wall (3] of this refuse collection container is made of high strength aluminum. * The inner wall 4 is constructed from wear-resistant titanium sheet. / I Daiwischen are file in particularly arranged manner Hutpro / "5)"> aluminum sheet either glued or spot welded connected to the Außenwandj3). The gaps are filled with light rigid foam compound everywhere. In the area of the bearing of the pressure plate and the feeder shovel, the metal sheets (4J are reinforced. The distances between the hat profiles are also narrower at these points. Another exemplary embodiment is shown schematically in FIG Hat profiles (5) have stepped angle profilesef6). In FIG. 5, instead of the angle profiles, corrugated sheet-metal-like profiles are made and only glued to the outer skin (_3J.

In Figure 6 is another embodiment with Z-profiles, but which are glued on both sides with the adhesive / 7), shown,

In a further embodiment, not detailed here is shown, both walls / 3) and (4) are made of high-strength, Made of wear-resistant aluminum alloy sheet. In figure 7 is the schematic representation of a lightweight construction for

the piston-cylinder unit for moving the AuSf: feeder shovel and the press shovel are shown. The piston rod 15 is made of high-strength precision steel tubing and the cylinder unit 12 (piston-cylinder unit 11, _(n 12)) is made of die-cast aluminum. Another advantage of the EgISjSIaIS compressed waste collecting container shown here is the good sound insulation

CO during loading and unloading compared to the current state of the art, appropriate garbage trucks. The subject shown here The invention has the following advantages over the prior art: 1) The dead weight compared to the steel versions Avoidance of .7 Unlawful Overloading of the

Total weight and axles,
2) More profitability in fleet operations with the same

Vehicle circulation by achieving one more load per shift. 3) Reducing the cost of increased tire wear, as well less pollution of the environment due to less noise during loading and

Unloading the vehicles
4) Lower operating costs due to lower tire wear, due to the elimination of overloading and the need for repairs

less, due to axles that are not overloaded 5) Longer service life of the body due to stainless »body materials ,
