An elongated tub includes a first end and a second end opposite the first end. An A-frame structure includes a force transfer vertex positioned adjacent to a top portion of the first end, a first pivot vertex pivotally and releasably coupled to an elongated frame, and a second pivot vertex pivotally and releasably coupled to the elongated frame. The A-frame structure includes a first force transfer beam coupled to the first end and coupled between the force transfer vertex and the first pivot vertex, a second force transfer beam coupled to the first end and coupled between the force transfer vertex and the second pivot vertex, and a separation beam coupled to the first pivot vertex and the second pivot vertex.

The present invention consists of a powered wood chipper mounted directly or indirectly to the frame of a utility type truck, thus eliminating the need for a separate trailer to carry said wood chipper to job sites. Said invention may also include a dump box, mounted directly or indirectly to the frame of the utility type truck, and whereby said dump box may be a sideways tilting assembly or may have a fixed position and incorporate a slanted or tilting floor assembly. Said dump box may also include a unique horizontal dump door arrangement with both an upper and lower doors. Presence of said lower dump door allows the dump box to discharge its load at a distance from the utility type vehicle. Said dump box may also feature slanted side or top surfaces, which may allow for greater visibility from the cab of the utility type vehicle and/or greater aerodynamics. These slanted side or top surfaces also allow the overall vehicle to have a narrower or lower profile and a lower center of gravity, leading to improved handling and safety for the work crew.

Systems and methods for securing a tank to a chassis. In an embodiment, a vehicle includes a chassis and a tank having a proximal end and a distal end. The proximal end is coupled with the chassis for pivotal movement with respect thereto. The vehicle also includes a structural pad coupled to the tank and at least one rib extending from the structural pad. The at least one rib has at least one aperture defined therethrough. At least one fluid cylinder is coupled with the chassis. The at least one fluid cylinder is coupled with a pin aligned with the aperture. Actuation of the at least one fluid cylinder causes the pin to move between a first position wherein the pin is not received within the aperture and a second position wherein the pin is received within the aperture.

An article transport vehicle (V) includes: a carriage body (1); and a transfer device (3) that is mounted on the carriage body (1) and is configured to transfer an article. The transfer device (3) includes an article support unit (32); a linking support unit (31) that links the article support unit (32) to the carriage body (1), and a drive unit (D). The linking support unit (31) includes a first shaft support portion (311) that is linked to the carriage body (1) so as to be swingable around a first shaft (A1), the article support unit (32) includes a second shaft support portion (321) that is linked to the linking support unit (31) so as to be swingable around a second shaft (A2), and the drive unit (D) includes a first drive unit (33D) and a second drive unit (34D).

A power unit with manual override control for a hydraulic system having an initial state and at least one operational state is provided, comprising: a tank for storing hydraulic fluid that moves between a first chamber and a second chamber of a hydraulic cylinder; a pump that routes the hydraulic fluid in and out of the tank; a first relief valve; a first solenoid valve configured to shift between a plurality of positions based on the at least one operational state of the hydraulic system; a first check valve connected to the first solenoid valve; a manual override control unit comprising: a second check valve; and a second solenoid valve configured to shift between a plurality of positions based on activation of a manual override control, wherein the activation of the manual override control returns the hydraulic system from the at least one operational state to the initial state.

A remotely operated hydraulic system is configured to engage an unloader in a semi-trailer. The remotely operated hydraulic system includes a solenoid mechanically coupled to the semi-trailer. The solenoid is further mechanically coupled to at least one air input line and at least one air output line. A receiver is electrically coupled to the solenoid and communicatively coupled to a remote control. The receiver is configured to open and close the solenoid based on a signal from the remote control. An air cylinder is mechanically coupled to the at least one air output line and a manual valve. Receiving air into the air cylinder operates to open the manual valve. A motor is mechanically coupled to the air cylinder and the unloader; wherein hydraulic pressure from the manual valve is configured to turn the motor and thus the unloader.

In a dump truck of the type having a frame mounted on ground wheels, a dump box having a floor, two side walls, a front wall at a front end and an open rear end with a tail gate where the dump box is supported on the frame for movement between a lowered position for storing and transporting materials and a raised position where the front end is elevated for dumping the materials out of the open rear of the dump box under gravity, the side walls are tapered so that a spacing at the front end is less than a spacing at the rear end so that the materials as they slide forwardly come away from the side walls to reduce pressure on the side walls and aid the sliding.
