A dumping vehicle includes a vehicle elevation system for elevating a body of a vehicle. The system can use one or more components of a vehicle as a main support against which a vehicle body is elevated. In certain examples, a suspension device of the vehicle can be used as the main support. The system further includes an elevation device arranged between the suspension device and a vehicle frame and configured to elevate the vehicle body by lifting the vehicle frame against the suspension device.

A loading amount accumulation device includes a loading amount storage section 403 storing a loading amount, a loading amount calculation section 402 accumulating load weight data about a transport object in a working front to the loading amount, and updating the loading amount by the value after being accumulated, a difference calculation section 404 calculating a difference between a loaded amount of a vessel and the loading amount, an accumulation success/failure determination section 405 comparing an absolute value of the difference and a value Dth, determining that accumulation has failed when the absolute value is larger than the value Dth, and outputting a result, a loading amount correction section 406, when the failure is output as the result, performing correction so as to set the loaded amount data as the loading amount, and updating the loading amount by the corrected loading amount, and an output section outputting the loading amount.

A haulage vehicle includes a vessel 3, hoist cylinders 10, a control valve device 16 that controls a supply or discharge of pressurized oil to or from the hoist cylinders 10, a controller 35, and a tilt angle detector 31 that detects a tilt angle of the vessel 3. The controller 35 compares a down assist performing angle, which is a tilt angle preset to determine whether negative pressure control processing needs to be performed for offsetting a force applied in a direction that would cause the hoist cylinders 10 to extend, with the detected tilt angle and, if the detected tilt angle is determined to be equal to or greater than the down assist performing angle, outputs a control valve signal to the control valve device 16 so that the valve is opened to forcibly discharge pressurized oil from the hoist cylinders 10.

When a tilt in a right-and-left direction occurs in a cargo bed (9) being raised due to imbalance of excavated materials, the tilt is detected as a roll angle (?R), and it is determined whether the absolute value (|?R|) of the roll angle is not less than an imbalance determination value (?2) (S4). When the absolute value is not less than the imbalance determination value (?2) (Yes in S4) and the roll angle (?R) is positive (the cargo bed (9) is rising to the right) (Yes in S8), an oil supply amount (VL) to a hoist cylinder (11) on the left side is increased, and an oil supply amount (VR) to a hoist cylinder (12) on the right side is decreased (S9). When the roll angle (?R) is negative (the cargo bed (9) is rising to the left) (No in S8), the oil supply amount (VL) on the left side is decreased, and the oil supply amount (VR) on the right side is increased (S10).

A split chassis system includes a first chassis base portion that is configured to house a first component and a second chassis base portion that is configured to house a second component. The second chassis base portion is positioned adjacent the first chassis base portion such that a first chassis coupling member included on the first chassis base portion is coupled to a second chassis coupling member included on the second chassis base portion. The split chassis system further includes a leveling subsystem that is coupled to the first chassis base portion and the second chassis base portion. The leveling subsystem aligns the first chassis base portion and the second chassis base portion such that the first chassis base portion and the second chassis base portion substantially maintain coplanarity when the first chassis coupling member is coupled to the second chassis coupling member.

A method and an arrangement for optimizing load position in relation to a transportation vehicle, comprising a platform arranged to the transportation vehicle for receiving a load; an actuating device for moving the platform in relation to the transportation vehicle; a sensing device configured to generate a vehicle sensing signal and/or a non-vehicle sensing signal; a controlling device configured to receive at least one of the vehicle sensing signal and the non-vehicle sensing signal; generate controlling commands based on the received at least one of the vehicle sensing signal and the non-vehicle sensing signal; and transmit the controlling commands to the actuating device; wherein the actuating device is configured to receive the controlling commands and to move the platform in relation to the transportation vehicle based on the controlling commands.

There is disclosed a method of operating a tipper vehicle, the tipper vehicle comprising a tipper body pivotably moveable with respect to a frame with a hydraulic cylinder disposed therebetween and actuatable to pivot the tipper body. The method comprises monitoring at least one of (i) a pressure parameter relating to the hydraulic pressure within the hydraulic cylinder and (ii) an angular positional parameter relating to the angular position of the tipper body; determining a maximum permissible vehicle speed based on at least one of the monitored (i) pressure parameter and (ii) angular positional parameter; and displaying the maximum permissible vehicle speed.

A computer system comprising a processor device configured to: initiate a dumping procedure of a load by tilting a dump body of a working machine by activating at least one tilting actuator connecting a working machine frame with the dump body, determine that the dumping procedure has reached a pre-defined state at which a sub-part of the load is maintained in the dump body, instruct the working machine to move in a forward direction to discharge at least a portion of said sub-part of the load maintained in the dump body.

A technique facilitates delivery of bulk materials at a desired site, such as a wellsite. According to an embodiment, a silo is pivotably mounted to a trailer, such as an over-the-road trailer. An actuator is coupled between the silo and the trailer to enable transition of the silo between a transverse position for transport and an upright position which facilitates outflow of the bulk material. The system also may comprise various other features used alone or in combination, such as pivotable wings, a foldable trailer, and an adjustable suspension which allows a frame of the trailer to be positioned firmly on the ground.
