Road Paver With Viewing Indentation In Material Container
The present invention relates to a road paver for paving paving material in a paving direction (a), comprising a machine frame, a driver's platform, a drive motor, a chassis with at least a left travel unit and a right travel unit, a material container arranged at the front of the road paver in the paving direction (a) for receiving paving material, the material container comprising a left container half and a right container half, which each have a container floor, a rising container sidewall and a rising container rear wall, and a longitudinal conveying device configured to transport paving material from the material container to a paving screed arranged at the rear of the road paver in the paving direction, wherein the container halves can be moved out of a filling position in order to move the paving material onto the longitudinal conveying device, wherein at least one container half has a viewing indentation, which extends from the container rear wall to the container floor in such a way that the ground can be viewed by the operator on the driver's platform through the viewing indentation.
Automatic roller path tracking and mapping for pavement compaction using infrared thermography
Disclosed is a thermal-based automatic roller tracking and mapping system for roller path tracking and mapping in pavement compaction. Accuracy in estimation during roller position tracking and mapping for pavement compaction through the use of thermal imaging is achieved. The tracking and mapping system utilizes an infrared camera for automatic roller path tracking and mapping in pavement construction. The tracking and mapping data associated with the movement of the roller vehicle during compaction of the surface can be generated and visually represented in a user interface accessible to the operator of the roller vehicle. Based on the tracking and mapping data that is generated in real-time and presented to the operator in the user interface, the operator can make adjustments to the roller vehicle and path, as necessary.
Feed material processing device and method for applying, distributing and compacting feed material in defined layer heights
A feedstock processing apparatus for applying, distributing, and compacting feedstock in defined layer heights, including a chassis with a traction drive and a first and second undercarriage. A frame structure connects the two undercarriages over a span width of the feedstock processing apparatus. A material feeding device is coupled to the frame structure. A material distributing device is coupled to the material feeding device and is displaceable in certain sections over the span width and configured to apply the feedstock in layers on soil in different, predefinable height positions between the undercarriages. A compacting device is displaceably mounted on the frame structure and/or the material distributing device. The compacting device and the material distributing device can be displaced in a manner dependent on one another respectively along a predefinable movement path.
DRUM OF COMPACTOR
A drum of a compactor includes a vibratory system having a shift assembly. The shift assembly includes an actuator and a shift fork assembly. The actuator includes a cylinder and a rod member defining a first end and a second end. The rod member includes an end portion extending from the second end towards the first end. The end portion has a first hardness value. The shift fork assembly includes a fork defining a through-aperture to receive the end portion therein to couple the rod member with the fork. The fork defines an engagement surface that faces the through-aperture. When the rod member is coupled with the fork, the engagement surface of the fork engages with the end portion of the rod member. The engagement surface of the fork has a second hardness value that is same as the first hardness value of the end portion of the rod member.
