The present invention relates to a rubber tire roller for ground compaction, comprising a machine frame and an operating platform and front and rear undercarriages supporting the machine frame, wherein the undercarriages each comprise at least one wheel. A fundamental idea of the present invention lies in viewing indentations that are open to the side.

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.

The present invention relates to a method of controlling operation of a vibratory roller (1) comprising a roller drum (3) and a vibratory mechanism (2) having at least two amplitude settings. The method comprises operating the vibratory mechanism (2) in one of said at least two amplitude settings; maintaining a predefined phase angle by controlling the vibration frequency of the vibratory mechanism (2); monitoring a bouncing indication value (BIV), said bouncing indication value being calculated based on an acceleration signal indicative of the vertical acceleration of the roller drum (3); and turning off the vibratory mechanism (2) upon detection of a resonance meter value (BIV) that exceeds a predetermined bouncing value (BV), thereby preventing the vibratory roller from operating in a bouncing mode of operation.

A machine has a chassis and at least one propulsion device configured to support the chassis. The machine also has a machine control module configured to control operations of the machine. Further, the machine has a modular sensor bay configured to be attached to the chassis. The modular sensor bay includes a position sensor configured to determine a position of the machine. The modular sensor bay also includes an imaging device configured to generate an image of at least a portion of surroundings of the machine. The modular sensor bay includes a control module configured to control operations of position sensor and the imaging device. In addition, the modular sensor bay includes a harness configured to electrically connect the modular sensor bay with the machine control module.

A construction machine comprises: a system region that can be rotated about an axis of rotation relative to a machine frame; at least one electrical load (50) in the rotatable system region; and an induction energy-transfer assembly (26) for wirelessly transferring energy into the rotatable system region, the induction energy-transfer assembly (26) comprising a transmitting assembly (27) having at least one transmitting coil (28, 30) and, in the rotatable system region, a receiving assembly (32) having at least one receiving coil (34).

A vibratory compactor is disclosed which may include a chassis, a prime mover supported by the chassis, and at least one roller supporting the chassis. The at least one roller may be adapted to emit both conventional vibrations and oscillatory vibrations.

An electric roller (1) includes: a pair of front and rear compaction wheels (a front wheel (R1) and a rear wheel (R2)); a vehicle frame (2) rotatably supporting the compaction wheels; at least one compaction-wheel electric motor (front-wheel electric motor (M1), right rear-wheel electric motor (M2), and left rear-wheel electric motor (R3)) to drive the compaction wheels; at least one compaction-wheel inverter (front-wheel inverter (J1), right rear-wheel inverter (J2), and left rear-wheel inverter (J3)) to control rotation speed of the compaction-wheel electric motor; at least one battery (K) to supply power to the compaction-wheel electric motor and compaction-wheel inverter; and a control unit (3) to output a signal to the compaction-wheel inverter according to a degree of inclination of a forward-backward lever (17), wherein the electric roller (1) has no internal combustion engine and uses only the battery (K) as a power source for the compaction wheels.
