Abstract:
A road finisher with a chassis; a front bucket on the chassis, for receiving packing material; a conveying device on the chassis, for conveying the packing material from the bucket to a rear spreader; a screw arrangement on the chassis positioned transversely with respect to a longitudinal axis of the road finisher and in front of a consolidation plank, the consolidation plank being extendable width-wise; the consolidation plank being connected to the chassis via pulling arms; the consolidation plank, floatable on the packing material, being divided centrally in the direction of the longitudinal axis into two plank halves; means connecting said two plank halves, for adjusting the inclination of said two halves with respect to each other; the improvement comprising:(a) a pair of outer side cheeks, one side cheek positioned outboard of each consolidation plank halve, each said side cheek connected to said chassis;(b) a pair of clamping devices, the clamping force of each device which can be set by means of a cylinder articulated on the chassis, each cylinder being positioned on the chassis toward the front thereof, in the direction of travel in relation to the consolidation plank halves, each clamping device including a flexible cable means extending between the cylinder to a lower region of each adjacent outer side cheek, the cable means supporting the consolidation plank in tension, as the road finisher moves forward, whereby twisting of said consolidation plank and widening of a gap between consolidation plank halves is minimized.
