Paver or feeder vehicle with pushing device for a material handover process

Abstract

A paver (1) or feeder vehicle (11) comprises a material bunker (4,12) for receiving a paving material (3), and a pushing means (10,10',14,14') fixed forward of the material bunker at a chassis, such that pushing rollers of the pushing means (10,10',14,14') may dock to rear tires (17) of a truck (15). The pushing rollers comprise a pair of first pushing rollers (19,19') mountable in a first position (P1,P1') in a seat of a traverse of the pushing means (10,10',14,14'). Either the pushing means (10,14) is expandable by at least one changeable attachment (21) to which the first pushing rollers (19) may be mounted in a second position (P2) further forward with respect to the first position (P1), or the pushing means (10',14') comprises a pair of second pushing rollers (25') which may be selectively positioned forward of the first pushing rollers (19').

Description

technical field [0001] The invention relates to a road finishing machine or a charging vehicle suitable for a road finishing machine according to the preamble of claim 1 . Background technique [0002] A road finishing machine for preparing paving layers from paving material and a charging vehicle for supplying the road finishing machine with paving material to be laid each comprise a material hopper for storing paving material therein for its operation. The individual material hoppers of the aforementioned motorized road builder are supplied with paving material from trucks on site. The supplied paving material is dumped from the truck into the corresponding material hopper. For the material transfer process, the road finisher and the charging vehicle each have an ejector at the front, in front of the corresponding material hopper, to which the truck is rearwardly docked via its rear tires. The docking to the ejecting device enables the truck to be ejected at a predetermi...

AI Technical Summary

Problems solved by technology

However, due to their high weight, the entire ejector may only be repositioned to a certain extent

[0010] However, for trucks with longer tipping body projections, as they are used in some countries, the well known ejector devices are not sufficient to butt the ejector rollers fixed thereon to the rear tires of such trucks

Therefore, during the material transfer process, a truck with a tipping body that exceeds the length cannot be pushed ahead at a predetermined distance by a road finishing machine or a charging vehicle

Therefore, it is difficult to maintain a predetermined distance between the truck and the following road finisher or charging vehicle for dumping paving material, since the truck driver himself has to adjust the distance to the road finisher or charging vehicle

This increases the risk of a collision between the truck and the following road finisher or loading vehicle
