An apparatus for testing vehicle stone chippings is disclosed. The apparatus includes a stone chipping rig having a chassis. The chassis includes a first end, a second end, and a longitudinally extending tongue extending from the second end. A rolling fixture is coupled to the first end of the chassis. A stone chipping test device is coupled to the first end of the chassis adjacent to the rolling fixture for measuring an impact force of a stone that strikes the stone chipping test device. The apparatus further includes a pilot vehicle used to receive the stone chipping rig so as to measure the impact force of the stone launched off the pilot vehicle wheels when the pilot vehicle travels on a road with loose gravel. The stone chipping rig is defined as a test vehicle towed at a fixed distance behind the pilot vehicle.

A control method to operate a scraper over ground, the control method comprising: receiving a signal indicative of a desired attack angle between a cutting edge of the scraper and the ground; receiving a height control signal to control a cutting edge height; receiving one or more measuring signals from one or more sensors, calculating a measured attack angle based on the one or more measuring signals; comparing the measured attack angle and the desired attack angle; and outputting at least one control signal commanding movement of a bowl of the scraper based on the height control signal and a result of the comparing the measured attack angle and the desired attack angle.

A ground scraper (10) including: a bowl (12) for holding excavated ground material; a cutting edge (14) mounted at a mouth of the bowl (12) for excavating the ground material; an apron (26) pivotally mounted to the bowl (12) for closing the mouth of the bowl (12); and a hitch assembly (28) including a draft tube (32) and a pair of draft arms (34) extending from the draft tube (32) and pivotally coupled to the bowl (12). Each draft arm (34) including a first portion (36) angled with respect to a second portion (38).

An excavator according to an embodiment of the present invention includes a lower traveling body, an upper turning body with an attachment mounted on the lower traveling body, and a controller installed in the upper turning body. The controller is configured to restrict movement of the lower traveling body based on information about terrain around the upper traveling body.

A scraper having a frame with a first removable sidewall removably coupled to the frame, a second removable sidewall removably coupled to the frame, a rear bucket pivotally coupled to the frame and having a dump position and a carry position, the rear bucket comprising a first rear sidewall positioned on a first side of the rear bucket and a second rear sidewall positioned on a second side of the rear bucket. Wherein, the first removable sidewall is positioned adjacent to the first rear sidewall and the second removable sidewall is positioned adjacent to the second rear sidewall. Further wherein, as the rear bucket transitions between the carry position and the dump position, the first and second removable sidewalls move relative to the surface of the corresponding first and second rear sidewalls.

A stopper assembly for a machine. The machine includes an implement. The stopper assembly includes a mount and a stopper. The mount is configured to be coupled to the machine. The stopper is configured to be pivotally coupled to the mount. The stopper is configured to restrict a pivotal movement of the implement when the stopper abuts the machine.

The disclosure relates to a device for filling a bucket in a loading and transport device having a rear part of a frame structure with articulated arms rotatable by power units, and second arms attached by pivots to a bucket which is in a transport position rotatable by power units around pivots to an emptying position. A middle part of the bucket bottom is connected by pivots with a panel having rotatable arms. The panel is rotatable around pivots and is arranged to lift and shift material on top of the panel to the rear part of the bucket, after which, the front part of the bucket bottom is empty and the bucket is fillable by pushing forward and rotatable around a horizontal shaft such that a centre of gravity of the bucket transfers onto a wheelbase of the loading and transport device.

A method for transferring endangered land from a first location in a first arrangement to a second location in the same first arrangement is disclosed. The method includes cutting, with a first cutting tool, a first pair of parallel rows in a first section of land of a first location. Then cutting a second pair of parallel rows, in the first section, that are perpendicular to the first pair of parallel rows creating an intersection of land between the first and second rows defining a transferable parcel and cutting a bottom side of the transferable parcel of land. The next step in the method is to lift the transferable parcel from a ground, placing the transferable parcel onto a portable bed, transferring the portable bed to the second location, and transplanting the transferable parcel into a receiving section of land of the second location in the same first arrangement.

A hydraulic system for a service vehicle wherein a hydraulic pump is powered by the vehicle engine to energize a hydraulic circuit that can power multiple interchangeable implements and hand tools. The multiple interchangeable implements include a lift assembly mounted to the flatbed of the truck. The lift assembly includes a mini skid steer which is hydraulically lifted on and off the platform of the flatbed. Additionally, the interchangeable implements include a crane arm that is disposed on the flatbed of the truck. Furthermore, the interchangeable implements also include a hydraulic arm assembly with several hydraulic attachments. These attachments may include a bucket, a drill, a breaker and the like.
