Systems, methods, and apparatuses can determine weight of a machine using rolling resistance. The machine may be electrified, either all-electrically powered or partially electrically powered. The rolling resistance can be determined based on motor signaling from one or more motor sensors that sense motor characteristics (e.g., drawn current) from one or more electric motors that drive the machine. The weight of the machine can be determined using the determined rolling resistance. Weight information can be output for display on a display and/or for storing in computer-readable storage onboard and/or offboard the machine.

The present invention proposes a ground compactor with a ground compaction drum rotating about a rotation axis during compaction of a substrate, wherein the ground compaction drum includes a deformation sensor for detection of an elastic deformation of the ground compaction drum in order to determine a degree of stiffness of the substrate.

An attachment roller that is configured to attach to a vehicle includes a main body, a plurality of rolling members, and at least one attachment arm. The rolling members are attached to the main body such that the rolling members are able to rotate and move the attachment roller. The at least one attachment arm is attached to the main body and configured to attach to the vehicle. When the attachment roller is attached to the vehicle by the at least one attachment arm, the attachment roller has a path of travel that is not aligned on or within and is substantially parallel to a path of travel of the vehicle.

A scraper coupled to a drum surface of a compactor is provided. The scraper includes an inlet port. The scraper includes a first channel fluidly coupled to the inlet port. The first channel extends across the scraper in a first direction. The scraper includes at least one second channel fluidly coupled to the first channel. The second channel extends across the scraper in a second direction. The scraper further includes at least one outlet port fluidly coupled to the second channel.

A suspension system for a pneumatic compactor includes a bolster frame and a steering input member coupled to the bolster frame. The suspension system includes at least one support member coupled to the bolster frame. The suspension system includes a support arm coupled to the at least one support member. The suspension system further includes a vibration absorber having a first end coupled to the bolster frame and a second end coupled to the support arm.

A water ballast for a compactor is disclosed. A ballast tank is installed under a cover plate having a plurality of holes. Through the holes of the cover plate, water falling onto the cover plate drains into the ballast tank. The edges all around the cover plate are slightly angled upwards in order to prevent water from draining out of the cover plate. Also, the water ballast has a ballast drain port on the compactor's frame. The ballast drain port is connected with a drain hole on the ballast tank by a drain hose so that it is used to drain out some water from the ballast tank.
