| 20090285631 | ROAD FINISHER - The present invention describes a road finisher for laying a paving material, comprising a material bunker for paving material and a spray jet module. In order to increase the spray carrying capacity in a structurally simple manner, it is suggested that a reservoir unit comprising a spray reservoir and a paving material reservoir should be arranged in the material bunker. | 11-19-2009 |
| 20100150650 | METHOD FOR LAYING A PAVING MAT - According to a method for laying a paving mat with a paving screed, the paving mat comprising a lane and a downwardly inclined slope beginning at a transition to the outside, the paving screed comprising a base screed and at least one extension screed which is extendable and retractable by a sliding motion in a sliding direction parallel to the base screed for varying the working width of the paving screed, the base screed and the extension screed having sole plates at the lower sides, with the sole plate of the extension screed being inclined laterally for forming the slope with the angle of the slope, a lateral position of the transition is first set relative to the base screed, during or after setting the lateral position a height difference is measured perpendicular to the planum between a fixed measuring location at the base screed and a location along a reference line extending parallel to the sole plate of the extension screed, the measured height difference being converted into a target value, and in the case of a variation of the working width and/or of the angle an occurring deviation of the height difference from the target value as caused by the variation is measured and automatically is corrected by a simultaneous height adaptation of the sole plate of the extension to the target value in order to maintain the set lateral position of the transition stationary. | 06-17-2010 |
| 20100150651 | PAVING SCREED AND A METHOD FOR LAYING A PAVING MAT - A paving screed comprises a base screed and extension screeds each of which is support via an extension guiding structure at a guidance fixed in the base screed such that each extension screed can be extended and retracted. A multiple point suspension is provided between the extension guiding structure and the guidance. A frame carrying the sole plate of the extension screed A is arranged below the extension guiding structure. Substantially vertical adjustment assemblies make it possible to adjust the height position of the frame via drives. A lateral inclination adjustment assembly is provided structurally separated from the adjustment assemblies either for the frame or within the frame for the sole plate of the extension screed. | 06-17-2010 |
| 20100209190 | PAVING SCREED - In a paving screed E for a road paver F, the paving screed E comprises a base screed G and extension screeds A at the front side of the base screed, the extension screeds A being extendable and retractable and pivotable relative to the base screed G, a base guiding structure | 08-19-2010 |
| 20100296867 | ROAD FINISHER - A road finisher ( | 11-25-2010 |
| 20100326067 | SELF-PROPELLED MACHINE - In a self-propelled machine F for processing paving material, the machine having a liquid cooled combustion engine M and at least one hydraulic circuit H containing hydraulic pumps | 12-30-2010 |
| 20100329783 | ROAD FINISHER WITH AUTOMATIC ENGINE CONTROLLER - The invention relates to a self-propelling machine for processing bituminous or concrete pavement material, in particular a road finisher or a feeder. The machine comprises an internal combustion engine as a primary drive source, a controller for the engine, said controller receiving control signals, at least one additional drive unit for functional and operational components of the machine as well as at least one hydraulic circuit comprising a hydraulic medium reservoir. The invention is characterized in that the controller is configured for automatically causing starting and/or stopping of the engine in response to receipt of at least one specific control signal. | 12-30-2010 |
| 20110091278 | SCREED FOR ROAD FINISHING MACHINE - In a screed with a basic screed and at least one extendable screed movable relative to the basic screed with a hydraulic cylinder and an electro-hydraulic control comprising a magnet-actuated directional control valve for at least controlling the direction of the hydraulic cylinder, the directional control valve for changing the rate of motion of the hydraulic cylinder is guided by an operator or automatically and is a proportional directional control valve (W) with proportional-electric direct actuation or proportional-electric-hydraulic pilot control. The proportional directional control valve for the hydraulic cylinder is connected on the actuation side with an electro-hydraulic control of a hydraulic system of the road finishing machine. | 04-21-2011 |
| 20110123267 | METHOD FOR LAYING DOWN A PAVEMENT, A SCREED AND A ROAD PAVER - In a method for laying down a pavement consisting of paving material with a screed of a road paver, in which a compaction unit, particularly a tamper, pre-compacts the paving material at cyclical work cycles with selectable stroke and selectable frequency while the pavement having a selectable pavement thickness) is in the process of being laid down at a selectable paving speed, at least the stroke is automatically adjustable in response to paving parameters, such as at least the paving speed and/or the pavement thickness, along a characteristic curve or in a characteristic map. In the screed the compaction unit comprises an adjusting mechanism which is operable during the ongoing paving work for adjusting the stroke of the compaction unit. | 05-26-2011 |
| 20110123270 | TAMPER OF A SCREED OF A ROAD FINISHING MACHINE - In a tamper of a screed having an eccentric shaft comprising an eccentric section and an eccentric bushing arranged thereon which is rotatably mounted in a connecting rod driving a tamper bar, the stroke of the tamper bar is adjustable by a relative rotation between the eccentric shaft and the eccentric bushing, and a tappet and a preselection area with two tappet stop positions defining two different tamper bar strokes are functionally provided between the eccentric shaft and the eccentric bushing, so that the tappet can be adjusted without tools to each tappet stop position by a reversal of the direction of rotation of the eccentric shaft to switch between the two strokes. | 05-26-2011 |
