A light-based measurement system is capable of directing a light beam to a cooperative target used in conjunction with a cable robot to accurately control the position of the end effector within a large volume working environment defined by a single coordinate system. By measuring the end effector while the device is in operation, the cable robot control system can be adjusted in real time to correct for errors that are introduced through the design of the robot itself providing accuracy in the tens or hundreds of micron range. A coordination processor runs control software that communicates with both the laser tracker and the cable robot. An action plan file is loaded by the software that defines the coordinate system of the working volume, the locations where actions need to be performed by the cable robot, and the actions to be taken.

The road construction machine according to the invention, in particular a slipform paver or curing machine for freshly manufactured concrete layers, has a machine frame 1 supported by running gears 3A, 3B, 4A, 4B, on which machine frame a working device 11 is provided, which has a working means 18 that can be moved in a direction running transversely to the working direction I, which working means is fastened to a carriage 13 which is guided on a linear guide 12 running transversely to the working direction. The carriage 13 is connected to a cable 15 that is deflected on one longitudinal side of the machine frame, the free ends of which are fastened to the cable drum 19 of a cable winch 16 on the other longitudinal side of the machine frame in such a way that the carriage can be moved in the transverse direction by rotating the cable drum. The road construction machine is characterised in that the cable drum 19 has a first and a second drum half 20, 21, one end of the cable 15 being fastened to one drum half 20 and the other end of the cable being fastened to the other drum half 21. The cable winch 16 can assume a first operating mode in which the first and second drum halves 20, 21 are connected to one another in such a way that the carriage 13 is moved by rotating the first and/or second drum half. The cable winch 16 can assume a second operating mode in which the first and second drum halves 20, 21 can be rotated in opposite directions at least in one direction of rotation, so that the cable tension can be adjusted by rotating one drum half relative to the other drum half.

A conveyor mold system for slip forming a concrete barrier has a concrete paving machine having a main frame having machine legs and machine tracks, an auger system for receiving concrete, a barrier paving mold having a hopper for receiving concrete from the auger system, a conveyor assembly main frame having a front roller and a rear roller, and a belt having a pattern with the belt positioned on the front roller and the rear roller.

A light-based measurement system is capable of directing a light beam to a cooperative target used in conjunction with an aerial robot to accurately control the position of the end effector within a large volume working environment defined by a single coordinate system. By measuring the end effector while the device is in operation, the aerial robot control system can be adjusted in real time to correct for errors that are introduced through the design of the robot itself providing accuracy in the tens or hundreds of micron range. A separate coordination computer runs control software that communicates with both the laser tracker and the aerial robot. An action plan file is loaded by the software that defines the coordinate system of the working volume, the locations where actions need to be performed by the aerial robot, and the actions to be taken.

A stencil device for forming configurations in deformable material includes a first member having ridge portions integrally joined to channel portions that promote the insertion of the ridge portions of the first member into deformable material; and a second member having ridge portions integrally joined to protrusion portions that promote the insertion of the ridge portions of the second member into deformable material; whereby, the first and second members ultimately form a design pattern across a preselected surface of deformable material by alternating the insertion and removal of said first and second members across the preselected surface of the deformable material.

An adjustable width mold apparatus for a slipform paver includes a center portion and left and right sideform assemblies. The center portion has left and right lateral ends. Left and right adjustable width support assemblies are connected between the sideform assemblies and the center portion. One or more spacers may be received between each sideform assembly and the center portion to adjust the width of the mold apparatus. The spacers may be hung on a plurality of hanger rods. Each of the hanger rods may have a hydraulic nut on one end thereof for clamping the spacers between the sideform assembly and the center portion.
