A screw jack assembly includes a first body defining a longitudinal axis and a screw drive disposed within the first body. The screw jack assembly also includes a second body movable relative to the first body and coupled to the screw drive, and a first gear coupled to the screw drive. The screw jack assembly further includes a handle assembly having a tube member coupled to the first body. The handle assembly also includes a second gear coupled to the first gear. The handle assembly further includes a handle member coupled to the second gear and adapted to rotate about a rotational axis substantially perpendicular to the longitudinal axis. The handle member is adapted to selectively rotate between an operating position and a stowed position about the longitudinal axis based, at least in part, on rotation of the tube member relative to the first body along the longitudinal axis.

A system for operating an auger assembly includes a controller configured to receive data detected by one or more sensors. Further, the controller is configured to determine an operational parameter associated with a movement of a screed assembly based on data. Also, the controller is configured to control a position of the auger assembly based on the operational parameter such that the auger assembly aligns with respect to the screed assembly at a predetermined distance with respect to the screed assembly.

The disclosure refers to a road paver fur producing a paving layer, comprising a chassis and height-adjustably mounted paving screed for compacting a paving material, wherein the paving screed has at least one external control station with a control device comprising at least one control device for setting process parameters and at least one display for displaying process parameters. The road paver further comprises a projector which is adapted to project at least one of the process parameters set on the operating panel and/or displayed on the display onto at least one projection area so that the projected process parameter is visible, in particular for an operator of the paving screed. The disclosure also refers to a method for projecting a process parameter by means of a projector of a road paver.

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.

An asphalt paver machine includes a main screed and an extender screed. The extender screed is coupled and configured to move laterally relative to the main screed. The extender screed includes a first screed carriage movably coupled to the main screed by a first cylinder and a second cylinder diagonally arranged relative to one another, and a second screed carriage movably coupled to the first screed carriage by a third cylinder and a fourth cylinder diagonally arranged relative to one another.

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 telescoping support assemblies are connected between the sideform assemblies and the center portion. Laterally inner ends of the telescoping support assemblies are connected to the center portion laterally inward of the respective lateral ends of 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.

A paving machine is disclosed. The paving machine may have a screed assembly having a left screed section and a right screed section. The paving machine may also have a crown actuator configured to pivot the left and right screed sections about the centerline. The paving machine may have a crown profile sensor configured to detect the crown profile (DP), and a cross slope sensor configured to detect a cross slope (QNL*, QNR*) of the screed assembly. Further, the paving machine may have a controller configured to determine the crown profile (DP) and a cross slope (QNL*, QNR*) of the screed assembly. The controller may calculate a left cross slope (QNL) of the left screed section and a right cross slope (QNR) of the right screed section based on the determined crown profile (DP) and the determined cross slope (QNL*, QNR*), and display the crown profile on the display device.

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.

According to one example, a screed assembly for a paver is disclosed. The screed assembly can include an end gate, a screed extender and a stowage apparatus. The screed extender can be selectively connected to the end gate via a first one or more quick attachment mechanisms. When connected, the screed extender can be configured to operably position the end gate relative to a main screed. The stowage apparatus can have a second one or more quick attachment mechanisms for selectively coupling the stowage apparatus to the end gate. The stowage apparatus can be movable from a first position for transportation of the paver where the end gate is coupled to the stowage apparatus and the end gate is positioned behind the main screed to a second position during operation of the paver where the end gate is decoupled from the stowage apparatus and the stowage apparatus is positioned adjacent the main screed.
