Monitoring device for a slipform paver for monitoring the compaction of concrete and a method for monitoring the compaction of concrete during operation of a slipform paver
11525224 · 2022-12-13 · ·

A device is provided for monitoring the compaction of concrete introduced into a slipform of a slipform paver by means of at least one concrete compacting device that has an asynchronous motor for driving an unbalanced mass which generates vibrations. The monitoring device comprises an apparatus for monitoring the stator current of the asynchronous motor, the apparatus being configured such that a change in the compaction of the concrete is determined based on an analysis of the stator current. The apparatus for monitoring the stator current of the asynchronous motor is preferably configured such that the amplitude spectrum of the stator current is determined in order to analyse the stator current. It is advantageous that the compaction of the concrete is not monitored using sensors which are exposed to harsh ambient conditions during operation of the slipform paver.

Paver having elevation profile monitoring equipment and methods for operation thereof

A paver, in particular a slipform paver, has a machine frame supported by front and rear undercarriages and a paving device for the paving of material. The paver is provided with an apron monitoring device for generating elevation profile data or elevation profile signals describing the elevation profile of the material deposited in the apron of the paving device in a direction transverse to the working direction. A data or signal processing device receives the elevation profile data or signals. The apron monitoring device provides the data needed to allow the material to be spread more evenly across the working width of the paver during the feeding operation by means of a spreading device for spreading the material to be paved in a direction transverse to the working direction and/or to allow the spreading device to be controlled for improved spreading of the material after the paver has been fed.

Screed accessory for levelling uncured concrete surfaces
11479928 · 2022-10-25 ·

An accessory for levelling uncured concrete surfaces. The accessory includes a screed head with two height adjusting levelling cylinders (1), a slope cylinder (2), a coupling component (3), a blade (4), an auger (5), a roller (6), a vibrator (7) and a sprinkler system (8). The coupling component (3) includes a hand operated hinged latch with a hook able to be snapped in place in a single movement so as to pinch together the coupling component and a telescopic boom of a general-purpose vehicle. The slope cylinder (2) enables the screed head to be maintained continuously at ninety degrees to the horizontal.

Adjustable control point for asphalt paver

Systems and methods for controlling a construction machine, such as an asphalt paver, having a tractor, an implement coupled to the tractor via at least one tow arm, and a mast. A position sensor mounted to the mast may detect a geospatial position of the mast. An angle sensor may detect at least one angle associated with the mast. A control point may be calculated based on the geospatial position and the at least one angle. The control point may be spatially offset from a vector formed by a lengthwise extension of the mast. The at least one tow arm may be moved based on a comparison between the control point and a target point.
