摘要： A system and assembly including a modular edge compaction wheel with multiple separable sections to form edges of a substrate (e.g., an asphalt mat) at differing depths. After forming a portion of the substrate edge at an initial depth, sections of the modular edge compaction wheel assembly may be attached by stacking and fastening the sections together for forming another portion of the substrate edge at a greater depth. The edge forming assembly may include an activating mechanism to extend and retract the modular edge compaction wheel assembly.

摘要： A system for assisting an asphalt compactor in performing a directional change can include a controller configured to perform a turn-out for the asphalt compactor by steering the asphalt compactor at a desired turning angle on an asphalt mat; the controller configured to turn off a vibratory system for the asphalt compactor during the turn-out; the controller configured to slow down and stop the asphalt compactor after a desired distance into the turn-out; and the controller configured to move the asphalt compactor in an opposite direction and restart the vibratory system.

摘要： A scraper assembly for a construction machine includes a housing pivotally coupled to a frame of the construction machine for moving the scraper assembly between a stowed position and a deployed position. The scraper assembly also includes a scraper partially received within the housing. In the deployed position of the scraper assembly, the scraper engages with a machine component to remove material stuck to the machine component. The scraper assembly further includes a biasing device received within housing. The biasing device biases the scraper towards the machine component. Further, the biasing device travels in a substantially linear path for biasing the scraper towards the machine component.

摘要： A roller tool for a soil processing roller of a soil processing machine incudes a tool holder to be fixed on an outer peripheral side of a carrier casing. The tool holder has an attachment region for fixed attachment on an outer peripheral surface of the carrier casing and a tool holder opening elongated in the direction of an opening longitudinal axis for accommodating a replaceable tool shaft of a replaceable tool to be detachably fixed on the tool holder. The tool holder includes a first tool holder part, wherein the attachment region is provided completely on the first tool holder part, and a second tool holder part to be detachably attached to the first tool holder part. The second tool holder part, together with the first tool holder part, delimits the tool holder opening in the circumferential direction around the opening longitudinal axis.

摘要： Described herein is a process for paving a surface with an asphalt paving material, comprising the steps of laying asphalt paving material on a surface to be paved; and combining an asphalt rejuvenator and the asphalt paving material; wherein the asphalt rejuvenator and the asphalt paving material are combined immediately before, concurrently with, or immediately after the asphalt paving material is laid on the surface to be paved. The asphalt paving material may be virgin asphalt, or it may comprise reclaimed asphalt pavement and/or recycled asphalt shingles.

摘要： A roller assembly for smoothing an expanse of granular media such as golf bunker sand, snow, horse race track dirt, or other media. The assembly has one or more rollers having a longitudinal axis. Each roller includes wires spaced from the axis to define a roller surface. Each wire is resiliently flexible to distort inwardly in response to force of contact on, and to recover during release of force from, the granular media as the roller rotates about the axis on the granular media. A shaft extends along the axis of the roller assembly between the arms of a yoke with a handle extending therefrom. As the roller surface traverses the media, at least some of the media is flung outwardly of the roller, smoothing the expanse. The roller assembly may be manually operated or may be towed behind a towing apparatus.

摘要： An adjustable mass eccentric for a multi-amplitude vibratory mechanism can comprise a body and an internal cavity defined by the body such that the body surrounds the internal cavity. The internal cavity can include a first section, a second section, and a third section between the first section and the second section. The third section can define a volume and/or an area less than respective volumes and/or areas of the first section and the second section of the internal cavity. Filler material may be provided in the internal cavity and can migrate to and from the first, second, and third sections based on rotational movement of the body and internal cavity.

摘要： The invention relates to an impact compactor which includes a first part on which at least one non-round compactor drum is rotatably mounted; and a second part which is connected to, and movable relative to, the first part. The impact compactor also includes a damping arrangement which is connected between the first and second parts and which is configured to provide a damping function for the relative movement between the first and second parts. The damping arrangement includes an outer tubular member which defines a non-circular inner channel/passage; a non-circular inner shaft member which defines a first axis of rotation and which is positioned, at least partially, in the channel/passage defined by the outer tubular member; and at least one wedge formation which is wedged between the shaft member and the tubular member. The wedge formation is at least partially resiliently deformable and is configured to resist/oppose relative rotation between the shaft member and the tubular member about the first axis of rotation. One of the members is connected to the first part, while the other member is connected to the second part.

摘要： An earth working machine (10), in particular a road milling machine, a stabilizer, or the like, having a milling drum (30) that is mounted rotatably on a machine frame (11) and is populated or populatable on its outer circumference with working tools (31); the working tools (31) to come into contact, during working operation, with the ground that is to be worked to remove it; a drive unit (20) drives the milling drum (30) by means of a drive motor (21); an input drive shaft (33) couplable to the drive motor (21) is attached to the milling drum (30); and a ballast element, constituting a kinetic mass (57), increases the kinetic energy of the milling drum (30). The kinetic mass (57) is couplable to or decouplable from the rotatable milling drum (30), or a rotational member indirectly or directly coupled to the milling drum (30), via a shiftable coupling (55).
