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.

Various embodiments of a mining vehicle are disclosed. The embodiments provide mining vehicles that are battery powered rather than diesel powered. The embodiments also provide vehicles that have relatively high hauling capacity relative to their length and footprint (area). The embodiments also provide vehicles with improved forward and rearward ground visibility. In addition, the mining vehicles have a higher density compared to traditional vehicles, which helps to improve traction, as well as better vehicle handing and power density because of increased power relative to diesel powered vehicles.

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 scraper has an apron, a bowl, a cutting edge, a vehicle attachment, and a pivoting mechanism such that the scraper has a flat position and an angled position. In the flat position the cutting edge is in position to cut into dirt and store the dirt in the bowl, while in the angled position the scraper is rotated such that dirt within the bowl can drop onto the ground in front of the scraper.

An automated backslope cutting system which, based on a survey of an area, automatically adjusts a scraper blade during the cutting of a ditch backslope. The automated backslope cutting system generally includes a scraper which is automatically adjusted by a computing device to effectuate cutting of backslopes for a ditch based on a desired cut profile. The desired cut profile may be manually entered by the operator and automatically processed by the computing device. The area is surveyed with a positioning sensor to determine an optimal desired cut profile requiring a minimum number of cuts. A proximity sensor may be provided to accommodate for rotational movement of the cutting blade as the scraper performs cuts. A control software is provided for execution by the computing device to provide functionality including the automatic adjustment of hydraulic actuators controlling movement of the cutting blade as the scraper cuts the ditch and backslopes.

A system includes a first machine having a first bail member and a first push bar, at first end. The first bail member includes a first hydraulic cylinder. A first hook and second push bar, at second end. The second push bar includes a second hydraulic cylinder in fluid communication with first hydraulic accumulator. The second machine having second bail member and first push bar, at first end. The second bail member includes third hydraulic cylinder in fluid communication with second hydraulic accumulator. A second hook and second push bar, at second end. The second push bar includes fourth hydraulic cylinder. The first hook coupled to second bail member and second push bar of first machine is in mechanical contact with first push bar of second machine. The impact energy generated at beginning of push operation and pull operation is stored in first hydraulic accumulator and second hydraulic accumulator respectively.

A hybrid power train system for a tractor scraper is provided. The hybrid power train system may include a primary power source coupled to a first set of traction devices, a generator coupled to the primary power source, a first electric motor coupled to a second set of traction devices, an inverter circuit coupled to the generator and the first electric motor, an energy storage device coupled to the inverter circuit, and a controller operatively coupled to the inverter circuit. The controller may be configured to engage a first operation mode enabling electrical energy, supplied by the generator and the first electric motor, to be stored in the energy storage device, and engage a second operation mode enabling electrical energy, stored in the energy storage device, to be supplied to the first electric motor to drive the second set of traction devices.
