A truck bed mounted carrier system includes a frame assembly installable in a truck bed with lateral supports and outer main supports, inner supports that slide within the outer main supports, a center outer support, and a second inner support that slides within the center outer support. A carrier frame coupled to the frame assembly extends from and retracts into the truck bed, supported by radius supports that provide structural integrity when extended. The system features a pulley assist mechanism with gas springs that creates a counterbalance force, a mechanical drive assembly with sprocket and roller chain for movement control, and deployable transport stands for ground support during loading operations. Adjustable bed rail struts with locking mechanisms secure the system to the truck bed without permanent modification. Low-friction materials and strategically positioned slides ensure smooth operation throughout the extension and retraction cycles.

A method for determining a material distribution condition in a tipper body of a tipper vehicle during a tipping event, the tipper body having a longitudinal extension along a longitudinal axis, and being arranged to be pivoted about a transversal axis, perpendicular to the longitudinal axis, during the tipping event, the method comprising generating an image of a surface of the material in the tipper body during the tipping event, and determining the material distribution condition in the tipper body using the image. A method for controlling a tipping event using the method, to a system, and to a vehicle are also disclosed.

A control unit for preventing rollover of a tipper truck on inclined surfaces is disclosed. The control unit is configured to: receive sensor data from one or more vehicle sensors, wherein the sensor data includes a lateral inclination angle, establish compliance or non-compliance with a safety protocol, wherein compliance with the safety protocol is established if the lateral inclination angle does not exceed a predefined lateral inclination angle threshold, which represents a maximum allowable lateral inclination angle; abort tipping operation in response to non-compliance with the safety protocol; and adjust suspension systems in response to compliance with the safety protocol, such that a suspension adjustment angle counteracts the lateral inclination angle, and proceed with tipping operation once the suspension adjustment angle has compensated for the lateral inclination angle.

A method is disclosed for a vehicle including a vehicle body and a vehicle subsystem for load carrying configured to be increasingly tilted in relation to the vehicle body for load discharge during a tipping operation. The method includes (during the tipping operation) acquiring image data from a camera mounted on the vehicle body and configured to view a downward facing surface of the vehicle subsystem for load carrying, and determining respective distances from a location of the camera to two or more laterally spaced portions of the downward facing surface based on the image data. The method includes estimating a lateral deflection of the vehicle subsystem for load carrying based on the determined distances, and causing a tipping interruptive action to be performed responsive to the lateral deflection fulfilling a condition indicating rollover risk. Corresponding computer system, vehicle, computer program product, and non-transitory computer-readable storage medium are also disclosed.

A work implement tilt control system for a tracked vehicle having a frame and a work implement mounted to the frame, the system comprising: a lifting unit configured to controllably raise or lower at least part of the work implement; an input device actionable by a first and second types of external actions associated with raising or lowering of the work implement; and a vehicle computer configured to send a signal to the lifting unit to carry out a lowering cycle of the work implement in case the vehicle computer determines that a set of conditions has been met. In some cases, the set of conditions includes: (i) a movement characteristic of the tracked vehicle exceeds a threshold; and (ii) the input device has been actioned by the first type of external action since carrying out the most recent lowering cycle of the work implement.
