An axle assembly for a landfill compactor includes an axle housing, a carrier housing located proximate the center of the axle housing, a drain plug located on an underside of the carrier housing, and a guard. The guard is attached to the underside of the carrier housing with adhesive such that the guard covers the drain plug and is configured to protect and give access to the drain.

An obstacle detector of a construction vehicle includes a brake mechanism which includes: a first hydraulic closed circuit including a pump for rolling, which is equipped with a swash plate, and a motor for rolling, which is connected with the pump for rolling; a second hydraulic closed circuit including a first hydraulic passage communicating with one side of the pump for rolling and a second hydraulic passage communicating with another side of the pump for rolling, to actuate the swash plate; and a neutral valve provided in the second closed circuit. When an emergency brake is activated, at least one of a compressive returning force to compress a low-pressure side of the tilted swash plate for returning the swash plate to a neutral position and a decompressive returning force to decompress a high-pressure side of the swash plate for returning the swash plate to the neutral position is generated.

A compaction device for compacting a soil region includes at least one vibration unit and/or oscillation unit able to be driven by an electric drive motor. A soil contacting unit comprises at least one soil contacting element in contact with the soil region. The soil contacting unit comprises at least the electric drive motor and the vibration unit and/or the oscillation unit. At least one power supply unit supplies the electric drive motor with electric drive power. At least one electric plug device for releasably and electrically connecting the electric drive motor is provided between the electric drive motor and the power supply unit. At least one fixing device for releasably and mechanically fixing to the power supply unit is provided between the soil contacting element of the soil contacting unit and the power supply unit.

An electronic control unit for a compactor obtains a planned operating profile of the compactor, generates a predicted power expenditure schedule for the compactor based on the planned operating profile, determines, based on the predicted power expenditure schedule, that a predicted energy expenditure of the compactor exceeds an available energy of the compactor, generates a modified operating profile in response to determining that the predicted energy expenditure of the compactor exceeds the available energy of the compactor, and operates the compactor according to the modified operating profile.

A wheel assembly for a soil compactor comprises a plurality of wheels (20) mounted in succession on a main wheel carrier (24) in the direction of an operating wheel axis of rotation (B), wherein at least one third wheel, which is arranged between a first wheel and a second wheel in the direction of the operating wheel axis of rotation (B), forms an auxiliary assembly wheel (20.sub.5) and is mounted on the main wheel carrier (24) by means of an auxiliary wheel carrier (34), wherein the auxiliary wheel carrier (34) is firmly coupled to the main wheel carrier (24) in an auxiliary wheel operating state and is pivotable about a pivot axis and displaceable in the direction of the pivot axis in relation to the main wheel carrier (24) in an auxiliary wheel assembly state.

A method for operating a beacon light of a machine is described. The method includes activating, by a processing unit, the beacon light based on a signal to indicate an operational state of the machine. The signal corresponds to one or more machine parameters in the operational state of the machine.

A liner plate for a work machine has a frame with a frame surface and an axle opening, and a guard member at least partially disposed above the axle opening. The guard member has a lower face, a region of the frame surface and a region of the lower face define a volume. The liner plate includes a body portion defining an upper surface and a lower surface opposite to the upper surface. The body portion defines a first side surface and a second side surface. The body portion is adapted to be coupled to the frame surface proximate the first side surface. The body portion is adapted to be coupled to the guard member proximate the second side surface. Further, upon coupling of the body portion to the frame surface and the guard member, the body portion prevents at least some debris from entering the volume.

A tooth for a compactor vehicle that includes a base and a cap. The base comprises a body and a retention feature. The body defines an underside, configured to engage a wheel of the compactor vehicle, and an opposing cap-facing side. The cap comprises an outer surface and a retention feature. The outer surface defines a compaction surface. The retention features of the base and cap interlock with one another to secure the cap to the base. A cavity is defined in the underside of the base.

A wheel guard includes a guard member disposed on a compactor wheel. The guard member has a first side having a first portion and a second portion. The second portion is offset from the first portion such that to define a first stepped recess therein. The guard member has a second side disposed opposite to the first side. The first portion has a first cross-sectional thickness and the second portion has a second cross-sectional thickness such that the second cross-sectional thickness is lesser than the first cross-sectional thickness. The guard member has a first top surface defined by the first portion, and a second top surface defined by the second portion and partially by the first portion. The second top surface is offset from the first top surface such that to define a second stepped recess therein. The wheel guard includes a base plate and a wear pad coupled thereto.

An autonomous terrestrial compaction testing vehicle includes a compaction density meter coupled to the vehicle and a controller. The controller is communicatively connected to the compaction density meter and to a controller of a compactor machine that is compacting or has compacted an area of terrain. The controller is configured to autonomously control movement of the vehicle over the compacted area and control the compaction density meter to take a plurality of compaction density measurements at a plurality of locations of the compacted area.
