Material processing plant
First Claim
1. A self-propelled material processing plant comprising:
- a plant frame comprising front and rear ends;
endless tracks supporting the frame and operative to manoevre the plant over the ground in a self-propelled mode;
front and rear couplings provided on the plant frame for releasable engagement with respective couplings on first and second spaced apart wheeled units so that the plant can be suspended between the two units with the endless tracks out of contact with the ground in a transport mode of the plant;
lifting means operative to lift the plant so as to engage the couplings on the first and second wheeled units for suspended transport of the plant, said lifting means also being operative to allow the plant to be uncoupled from both units and to engage the ground via the endless tracks so that the plant can propel itself by the endless tracks and independently of the wheeled units; and
wherein the plant frame comprises a fixed support with said rear coupling mounted thereon, said support being movable downwardly with the plant frame under action of the lifting means to engage the second wheeled unit so as to suspend the rear end of the plant frame for transport purposes.

Abstract
A material processing plant e.g. a crusher or shredder (2) adapted to be suspended between a first wheeled unit (3) and a second wheeled unit (4) during transport, in which the first and second units have respective couplings, and in which the plant comprises: a plant frame; and front coupling and a rear coupling provided at the front and rear of the plant frame respectively; an arrangement of the front and rear couplings such that when the front coupling and the rear coupling of the plant frame are connected to the respective couplings of the first and second wheeled units, the plant (2) is suspended between the first and second units; and a lifting means (37) connected to one or both of the wheeled units (3,4), or to the plant frame, and operable to lift the plant for connecting the couplings of the plant frame to the respective couplings of the first and second wheeled units.
