摘要： In some implementations, a control system may include at least one total station prism connected to a screed assembly of a paving machine, and a controller. The controller may be configured to obtain paving information that indicates locations of edges of a mat of paving material deposited by the paving machine. The paving information may indicate the locations of the edges based on data collected using the at least one total station prism. The controller may be configured to determine, based on the locations of the edges, an operating plan for one or more compactor machines that are to provide compaction of the mat. The controller may be configured to transmit, to another controller for the one or more compactor machines, plan information that indicates the operating plan.

摘要： A construction machine in the form of a road paver or feeder vehicle includes a chassis and a hopper, wherein at least one lighting arrangement is mounted on the chassis. The lighting arrangement comprises at least one light source, and the lighting arrangement is configured to illuminate an area in front of the construction machine in the direction of travel. The construction machine further has an object detection system for detecting an object located in front of the construction machine in the direction of travel, and the illumination emitted by the lighting arrangement can be changed as a function of the detection of an object by means of the object detection system.

摘要： A method and system of verifying asphalt mat temperature values and location data generated by a paving machine includes identifying a location and temperature value of a threshold thermal characteristic of thermal data generated by the paving machine, and displaying the paver-generated location and temperature value of the threshold thermal characteristic on a display of the paving machine. The method further includes determining a location and temperature value of the threshold thermal characteristic by one or more external systems, and comparing the externally-determined location and temperature value to the paver-generated location and temperature value.

摘要： The present invention relates to a road paver, particularly a small road paver, for paving a subbase layer in a working direction (a), with a machine frame, a traveling mechanism, a material hopper for receiving paving material, a paving screed for smoothing and compacting the paving material, a transverse distribution device for distributing paving material in the working direction (a) in front of the paving screed and transversely to the working direction (a), the transverse distribution device being supported at the machine frame via a support housing, and a height adjustment device for vertical adjustment of the transverse distribution device relative to the machine frame, wherein the support housing is supported at the machine frame such that it is height-adjustable via a quick coupling apparatus, wherein the quick coupling apparatus comprises at least one oblong hole with an expanded insertion portion and a sliding device, wherein the sliding device can be inserted into the oblong hole through the expanded insertion portion, and wherein the sliding device in the inserted state slides in the region of the oblong hole outside the expanded insertion portion during vertical adjustment of the transverse distribution device through the height adjustment device, and wherein the sliding device is supported in a form-closed manner in a direction perpendicular to the height adjustment in this region. Moreover, the invention relates to a method for mounting a transverse distribution device on a road paver.

摘要： A screed control system for a screed system includes a controller communicably coupled to a position sensor and at least one of a screed pressure assist system, an extendable screed height system, and a tamper system. The controller is configured to receive a signal indicative of a position of an at least one extendable screed with respect to a main screed. The controller is also configured to determine a change in the position of the at least one extendable screed with respect to the main screed. The controller is further configured to control at least one of the screed pressure assist system, the extendable screed height system, and the tamper system based, at least in part, on the determination.

摘要： A paving machine for spreading, leveling and finishing concrete having a main frame, center module, bolsters laterally movably, and a crawler track associated with respective aft and forward ends of the bolsters. A bolster swing leg for each crawler track supports an upright jacking column. A worm gear drive permits rotational movements of the crawler track and the jacking column. A hinge bracket is interposed between each swing leg and a surface of the bolsters to enable pivotal movements of the swing leg. A length-adjustable holder engages the pivot pin on the hinge bracket and pivotally engages the swing leg. The holder permits pivotal motions of the swing leg in its length-adjustable configuration and prevents substantially any motion of the swing leg in its fixed-length configuration. A feedback loop cooperates with transducers keeping the crawler tracks position. The paving machine can be reconfigured into a narrowed transport configuration.

摘要： A road building machine wherein the danger of material falling out as the supply container is loaded is avoided. For this it is proposed that the container halves each have at least one shield which can be moved away as the container halves are folded up. Road building machines, more particularly road pavers and feeders are supplied with road building material from trucks, and, in order to receive the road building material the road building machines have supply containers with two movable container halves, and, when the supply container is filled, the invention helps prevents road building material from falling out from the supply container.

摘要： A drive-over conveyor for unloading fracking sand is designed to be towed as a highway semi-trailer includes a center frame structure containing a conveyor belt with two pivotal ramps on each side to be moved to a raised position standing upwardly and a lowered position extending outwardly. The ramps have sufficient length and the center structure has a low height to allow a highway semi-trailer to pass over a grate in the center structure. A platform is attached at the forward end with a king pin on the underside for engaging a towing platform of a highway tractor. A wheel and axle assembly including suspension of the axle for highway travel is mounted on a sub-frame pivotal relative to main rear frame for movement relative to the center frame structure from a lowered road position to a raised position allowing the center frame structure to rest on the ground.
