  • Patent number: 10961728
    Abstract: A wheeled hose moving device that is movable over a support surface and that is operable to lift and move a concrete supply hose at the support surface. The device includes a wheeled support including a hose lifting device and a hose support element. The hose lifting device is vertically movable between a raised position and a lowered position and is adjustable between a lifting state and a non-lifting state. The hose support element is adjustable between a support state and a non-support state. The hose lifting device is, when lowered to be at the hose, adjusted to engage and lift the hose. As the hose lifting device lifts the hose upward, the hose support element is automatically adjusted from the non-support state to the support state to support the lifted hose.

  • Patent number: 10907311
    Abstract: A method and a road finisher for creating a temperature field of a newly laid paving layer corrected for interfering-related temperature measurement errors. It is recognised that when the paving layer is paved, a measuring point is covered by an interfering object at a first time if, contrary to an expected material-specific cooling at a later second time during paving at the same measuring point, a larger temperature value particularly lying within a nominal temperature range than a temperature value measured to the preceding first time is measured, wherein instead of the temperature value detected at the first time a new temperature value is assigned to the measuring point in the temperature field.

The sensors are disposed at the screeding machine, which has a screed head assembly that is movable over uncured concrete to screed the concrete surface. The sensors include elevation sensors that sense an elevation of the screed head assembly relative to a reference plane established at the concrete area. The control processes data captured by said plurality of sensors while the screeding machine is screeding the uncured concrete surface. Responsive to the data processing of captured data, the control estimates a flatness or levelness or quality of the surface of the concrete being screeded. While the screeding machine is screeding the uncured concrete surface, the control generates an output indicative of the estimated flatness or levelness or quality of the surface.

The laser pointer generates a laser beam which is similarly directed at the paving material that has been distributed by the auger. The laser beam and the sonic signal meet at a common position on the paving material.

  • Patent number: 8998530
    Abstract: A method for laying down a pavement in which a compaction unit such as a tamper pre-compacts the paving material with a selectable stroke and at a selectable frequency while the pavement having a selectable pavement thickness is in the process of being laid down at a selectable paving speed, the stroke of the compaction unit is automatically adjustable in response to paving parameters, such as the paving speed and/or the pavement thickness, along a characteristic curve or in a characteristic map. The compaction unit includes an adjusting mechanism which is operable during the paving operation for adjusting the stroke of the compaction unit.

  • Patent number: 8974219
    Abstract: A modular tool for imparting profile characteristics into fluent cementitious material. The tool has an elongated base forming a permanently fixed blade, and at least one handle. The blade is configured to act as a dovetail to which any of several modular blades may frictionally fit in removable fashion. The fixed blade forms a deflector disposed to deflect removed cementitious material away from the handles. Other blades may fit by peg and socket engagement. The tool may have detachable rollers enabling the tool to advance at a controlled elevation along a wall being formed and shaped. A slide block may be arranged to engage the rollers so as to adjust their position on the tool. The tool may have integral bubble levels.
