Known in cross-section, rectangular hollow brackets composed of individual longitudinal and transverse metal sheets, which have two parallel, spaced-apart longitudinal cantan girders, each roughly square in cross-section, which are inseparable from each other via a common cover plate and bulkheads of the same height as the diaaei * Länggkaft & Entrfiger * vsrbimden sin £ _e Similar Trügarkonetruk-έ ionen for motor vehicles are also known from the German patent specification 897 953 ₃ Although the well-known transport hollow frames mentioned above have sufficient load-bearing capacity and sufficient bending and pre-winding rigidity for many purposes, they need to be tested for higher 3eleetunge ** In such a way across the longitudinal and transverse directions that the driver's control frame in one structure is complicated and expensive, and on the other hand its weight is undesirably high for the entire vehicle.

is, but the professional world has the fundamentals of a dagger Construction not recognized and for this reason also not used in Fahrseugbau. Furthermore, tfreßpchalen can are only produced in a limited maximum size, Which is why there are hollow rugs according to the French method Patent specification 850 676 described type on smaller vehicles, For example, Tferecnenkraftwagen, limited and, as from the Drawing of this French patent specification, are probably only intended for such.

By the invention, the object is to be solved at the outset Pahrieughohlrahaen erwähnton, beispielsveise in US i'atentschrift 2 8 ^ 6 263 and German Patent 897,953 described manner on the one hand a saving in weight and on the other hand, a; higher load capacity and higher bending and torsional rigidity.

For the purpose of solving this problem, there is a wooden chassis frame, irobeo special for crane cases, with advance notice continuous flat longitudinal sheets and feet connected to it Quorefiffening according to the invention characterized in that d & £ dia cross-sections represent the frame flat, below and on The longitudinal sheets delimiting the two long sides in the vertical transverse plane form a chioasene line

Hollow vehicle frames according to the invention are therefore suitable especially good for crane vehicles, as it is their frame are exposed to high bending and twisting loads, which latter especially with extended or »at issued Seitenctütccn are far htther than as if the Kronfahrseug only rests on its wheels, because then the Crane boom laid out further laterally or more heavily loaded can be"

Instead of bulkheads or in addition to these, 1 to * and 7 and 8 transversely sum of the hollow rafters Stiffening frame be attached. Such stiffening frames are shown in Figs. 9 to 12 of the drawings, in which the same, already described parts are in turn provided with bits with the same reference numbers »

According to FIGS. 9 and 10, such a stiffening frame can consist of one T-rails 20 to 28 in this way susanmen required that the individual transverse legs of the • T "-tfrofilee protrude into the Fahrseugrahnen hollow space. In a further embodiment, such a Reinforcement frame-according to the Pig. 11 and 12 of several L-shaped rails 29 to 36 be set up in such a way that that one leg 37 dee "L" profiles in each case The driver's eye cavity protrudes into it.

further refinement in a manner known per se adapted to the vehicle in question, but this is not Subject of the invention and is therefore not described in more detail. The wheels 38 of the vehicle in question are shown in FIG. of the drawings shown schematically in dash-dotted lines «

^ The nit of the invention compared to the known state The advances achieved in the art are in particular that hollow vehicle frames designed according to the invention Compared to known designs, it is significant in terms of weight are lighter and can be heavily loaded not only in the vertical direction, but also in particular have significantly greater torsional rigidity "which is particularly beneficial" when b «i spread out Side pockets open the door, for example with a horseradish «- boom, larger torsional moments tiuegaoct r.t will.
