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).

A compactor includes a compactor structure and at least one roller unit rotatably supported on the compactor structure about a roller axis of rotation. A roller heater is deployed in assignment with at least one roller unit. The roller heater is a liquid fuel-operated heating device with a burner region, a fuel pump for supplying liquid fuel from a fuel tank to the burner region and a combustion air blower for supplying combustion air to the burner region.

A concrete screed assembly broadly includes a plurality of elongated drum sections. The drum sections are interchangeably interconnectable in an end-to-end relationship to cooperatively form a rotatable concrete screed drum that is selectively variable depending on the drum sections interconnected to form the drum. The drum sections each present a concrete-forming outer surface configured to engage concrete as the drum is rotated. The drum sections each include opposite connection ends.

A curb former (10) includes a rotatable drive shaft (20), a gutter drum (80), and a curb profiling drum (100). The gutter drum (80) is secured to the drive shaft (20) such that the drive shaft (20) and gutter drum (80) rotate together. The curb profiling drum (100) is detachably secured relative to both the drive shaft (20) and the gutter drum (80). This configuration allows one curb profiling drum (100) to be replaced with another curb profiling drum (100) to change the profile of a curb resulting from a curbing operation using the curb former (10).

A soil working roller for a soil processing machine, in particular a soil compactor, comprising a roller shell (44) extending longitudinally in a direction of a roller axis of rotation (D) and delimiting a roller interior (26), at least one ballast unit (46, 48) arranged in the roller interior (26), characterized in that each ballast unit (46, 48) comprises at least one ballast element (54) supported with respect of the roller shell (24) by means of an elastic suspension assembly (58), wherein the at least one ballast element (54) is permanently coupled to the roller shell (24) by the suspension assembly (58) and is movable with respect to the roller shell in the radial direction, axial direction, and circumferential direction, and/or a plurality of ballast units (46, 48) is provided in the roller interior (26) arranged in series in the circumferential direction, wherein each ballast unit (46, 48) comprises at least one ballast element supported with respect to the roller shell (24) by means of an elastic suspension assembly (58).

A compaction drum can include an outer surface defining a width. The compaction drum also can include a plurality of pads disposed on the outer surface of the compaction drum and positioned in at least one row. Each of the plurality of pads can be disposed circumferentially spaced apart relative to one another on the outer surface. Each of the plurality of pads can define a first height. The compaction drum further can include a plurality of ribs disposed on the outer surface. Each of the plurality of ribs can be connected between adjacent pads of the plurality of pads. Each of the plurality of ribs can define a second height. The second height of each of the plurality of ribs can be approximately equal to the first height of each of the plurality of pads.

A drum for a roller compactor has an outer shell providing an exterior peripheral compacting surface and an interior for housing an excitation system used to vibrate the drum. The outer shell includes a non-elastic polymer with embedded reinforcing fibers.

A compactor includes a compactor structure and at least one roller unit rotatably supported on the compactor structure about a roller axis of rotation. A roller heater is deployed in assignment with at least one roller unit. The roller heater is a liquid fuel-operated heating device with a burner region, a fuel pump for supplying liquid fuel from a fuel tank to the burner region and a combustion air blower for supplying combustion air to the burner region.

A system and a method for controlling tire air pressure of a compactor having a plurality of tires. A weight distribution of the compactor is determined according to a per-tire basis. Target air pressures for each of the tires are determined in order to achieve a consistent compaction surface contact pressure across all of the tires or a set of the tires. Air pressure of the tires is controlled to achieve the target air pressures to make the compaction surface contact pressure consistent across all of the tires or the set of the tires.
