摘要： A work machine includes a frame, a sensor assembly, and an ultrasonic sensor. The frame includes a first portion and a second portion that includes a front bumper and is configured to pivot with respect to the first portion for steering the work machine. The sensor assembly is positioned on the first portion or the second portion of the frame and is configured to sense data for detection of obstacles within a first area around the work machine. The ultrasonic sensor is positioned on the front bumper of the second portion and is configured to sense data for detection of obstacles within a second area around the work machine, the second area outside the first area when the second portion is in an articulated position with respect to the first portion.

摘要： 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.

摘要： A guard for protecting a drain plug and a ground-facing surface of an axle housing on a machine including a first portion and a second portion. The first portion has a body configured to be mounted to the axle housing to protect at least portion of the ground-facing surface of the axle housing. The body includes an opening configured to allow access to and removal of the drain plug through the opening. The second portion is removably couplable to the first portion. When the second portion is attached to the first portion, the second portion covers the opening to protect the drain plug. When the second portion is removed, the drain plug is accessible and removable to service oil in the axle housing.

摘要： A device for ground compaction, comprising a frame and a drive motor supported by the frame, a vibration exciter driven by the drive motor and a ground compaction apparatus, in particular a base plate or a roller drum, that is connected to the vibration exciter, wherein the vibration exciter causes the ground compaction apparatus to vibrate at a fixed vibration frequency or within a vibration frequency range during a compaction operation, and wherein a conversion device for the conversion of vibrations into electric energy is provided which converts vibrations of the device for ground compaction into electric energy, wherein the conversion device comprises two spring-mass systems with different resonance frequencies, and wherein a control unit is provided which determines the degree of compaction of the ground from the electric energy obtained by the individual spring-mass systems, in particular the respective voltages. Moreover, the invention relates to a method for monitoring changes in the ground compaction produced with a device for ground compaction.

摘要： A compacting machine includes a frame supporting a compacting member and a monitoring system. The monitoring system includes a sensor, a computer-readable medium bearing a compacting member monitoring program, a controller, and an interface device in communication with the controller. The sensor is arranged with the compacting member to sense a parameter of its ground-engaging surface and to generate a surface parameter signal indicative of the parameter. The controller is in communication with the sensor to receive the surface parameter signal therefrom and is configured to execute the compacting member monitoring program. The compacting member monitoring program is configured to determine whether a piece of the material being compacted becomes adhered to the ground-engaging surface based upon the surface parameter signal satisfying a condition and to produce, through the interface device, an indicator alerting the operator once the surface parameter signal satisfies the condition.

摘要： A base for forming a tooth for a wheel of a landfill compactor vehicle is disclosed. The tooth comprises said base and a cap of a cast metal material formed on said base. The base comprises a block, a core and a lip. The block is adapted to be mounted on said landfill compactor vehicle wheel. The core, which is disposed on a cap-facing side of the base, is for receiving molten metal material during a casting operation and remains embedded in the cap. The lip is disposed around a periphery of the base and is also for receiving said molten metal material, in cooperation with the core. The lip at least partially surrounds the cap-facing side and the core and helps in reducing or preventing imperfections, such as cracks, which could otherwise form at the interface between the base and the cap following the casting operation.
