Abstract
Abstract A self-propelled tool-carrying vehicle for agricultural and industrial purposes and having a frame formed of two longitudinal beams and a driving motor arranged between the longitudinal beams without projecting upwardly beyond the plane formed by the upper surface of the longitudinal beams. All other driving and transmission means except the control means are likewise located below said plane so that the longitudinal beams are free for attachment of working tools or a loading platform at both ends and sides. Additional longitudinal beams of smaller dimensions may be tiltably mounted on said longitudinal beams and provided on their underside with teeth to permit the attachment of the working tools. The main longitudinal beams may be provided with telescopic extensions to provide further possibilities for attachment of working tools.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
154 words
A self-propelled tool-carrying vehicle for agricultural and industrial purposes, comprising frame means including a first pair of longitudinal beams each having an upper surface, and a second pair of longitudinal beams above said first pair and each having a lower surface facing the respective upper surface; a plurality of teeth on said lower surfaces distributed lengthwise of said second pair of beams; drive means arranged between said longitudinal beams and downwardly of the general plane of said frame means which is defined by said upper surfaces; and operating means for raising and lower said second pair of beams with reference to said upper surface for enabling connection of a working tool with said frame means by disposition of such tool on said upper surfaces and subsequent clamping between said upper and lower surfaces in meshing engagement of said teeth with corresponding teeth on said working tool so as to secure the latter against displacement.
Claim 2
Dependent Claim
154 words
A self-propelled tool-carrying vehicle for agricultural and industrial purposes, comprising frame means including a first pair of longitudinal beams each having an upper surface, and a second pair of longitudinal beams above said first pair and each having a lower surface facing the respective upper surface; a plurality of teeth on said lower surfaces distributed lengthwise of said second pair of beams; drive means arranged between said longitudinal beams and downwardly of the general plane of said frame means which is defined by said upper surfaces; and operating means for raising and lower said second pair of beams with reference to said upper surface for enabling connection of a working tool with said frame means by disposition of such tool on said upper surfaces and subsequent clamping between said upper and lower surfaces in meshing engagement of said teeth with corresponding teeth on said working tool so as to secure the latter against displacement.
Claim 3
Dependent Claim
25 words
A self-propelled tool-carrying vehicle as claimed in claim 1, said first pair of beams having unobstructed sides and end portions for attachment of working tools.
Claim 4
Dependent Claim
33 words
A self-propelled tool-carrying vehicle as claimed in claim 1; further comprising a driver''s seat mounted on said frame means in the region of one corner thereof at one end of said frame means.
Claim 5
Dependent Claim
51 words
A self-propelled tool-carrying vehicle as claimed in claim 3, said beams of said second pair having end portions adjacent said one end of said frame means; and further comprising mounting means pivotably mounting said end portions for displacement about a substantially horizontal axis extending transversely to the elongation of said beams.
Claim 6
Dependent Claim
16 words
A self-propelled tool-carrying vehicle as claimed in claim 3, said operating means being a fluid-operated ram.
Claim 7
Dependent Claim
23 words
A self-propelled tool-carrying vehicle as claimed in claim 1; further comprising telescopic extensions at opposite ends of said first pair of longitudinal beams.
Claim 8
Dependent Claim
29 words
A self-propelled tool-carrying vehicle as claimed in claim 1, said second pair of beams being coextensive with a major longitudinal portion of the respective beams of said first pair.
