1,246,190. Articulated vehicles. SOC. FIVES LILLE-CAIL, and SOC. DES APPAREILS DRAGON. 1 Dec., 1969 [6 Dec., 1968], No. 58535/69. Heading B7H. [Also in Division B2] A self-propelled crusher plant comprises: a crusher 14, Fig. 1, e.g. a jaw crusher or fixed or swing-hammer mill or roller mill, a supply assembly comprising a hopper 40 and a conveyer 42, a discharge conveyer 18, Fig. 2, for crushed material and a chassis. The chassis comprises a first chassis part 10 and a second chassis part 12 pivotally connected for relative movement about a horizontal pivotal axis at 34. The first chassis part 10 supported by a driving axle 30 and a steering axle 32, carries the crusher 14 and discharge conveyer 24. The second chassis part 12 is supported by a single steering axle 36. The two steering axles are interlinked by servomotors. During movements of the plant between sites the second chassis part supports the lower part of the supply assembly, whose upper part is pivoted at 44 to the first chassis part for movement about an axis parallel to the axis of connection of the two chassis parts. The supply assembly may be connected to the second chassis part by two hydraulic jacks 46 to permit lifting of the assembly. In operation, the supply hopper rests on feet 48 and is lowered by the jacks 46 and the chassis part 10 is supported on props 38. Discharge ground material is fed by the discharge conveyer 18 to a jib-mounted dumping conveyer 24.
