Disclosed is a dumping work determination system for a haulage vehicle provided with a body frame, a vessel and a drive mechanism for selective raising or lowering of the vessel. The system is applicable to the vehicle to determine a state of loading in the vessel in dumping work, and includes a body frame speed detector, a tilted state detector, a shake detector, and a payload-stuck state determination unit. Based on signals from the detectors, the unit determines whether or not the state of loading is a payload-stuck state. Specifically, the unit determines the payload-stuck state when the speed of the body frame is detected to have reached lower than a predetermined speed, the vessel is detected to have tilted to a predetermined position, and a state where the vessel can be considered to have no longer produced shakes is detected by the shake detector.

The present disclosure relates to a dump truck, comprising a hydraulic suspension system, a wireless communication system, capable of receiving information from a loading equipment, and a control unit, comprising processing circuitry coupled to the hydraulic suspension system and the wireless communication system, the processing circuitry being configured to receive, from the loading equipment, information about a weight of a load to be received by a container of the dump truck, and control the hydraulic suspension system to raise the container to a height as a function of the weight of the load to be received.

The present disclosure relates to a method of determining whether a frame of a work machine is approaching a tip over point. First and second loads upon respective first and second support arrangements of the frame are detected using respective first and second sensing means. Signals are generated indicative of the first and second loads and communicated to a controller. The controller is configured to generate an alert based upon the first and second loads when the first and/or second load signals indicate that the orientation of the work machine is approaching a tip over point.

There is disclosed a method of operating a tipper comprising a tipper body pivotably moveable with respect to a frame with a hydraulic cylinder disposed therebetween and actuatable to pivot the tipper body.

A method for stabilizing at least one frame part of a forest work unit involves determining a moment applied by a payload of the forest work unit to a frame part to be supported and determining a magnitude and direction of at least one support moment needed at least for stabilizing the frame part on the basis of the moment applied by the payload to the frame part to be supported. An arrangement for stabilizing at least one frame part of a forest work unit comprises means for carrying out said determinations.

The method comprises the steps of: (S1) measuring roll angle and pitch angle of the chassis structure and of the load carrying body during the lifting and lowering sequence, by means of the sensing means, (S2) determining absolute roll angle and pitch angle of the chassis structure and the load carrying body, respectively, with respect to a reference, (S3) determining a relative roll angle between the chassis structure and the load carrying body by comparing the measured roll angles of the chassis structure and the load carrying body when the load carrying body is pivotally mounted with respect to the pivot axis being substantially parallel to the pitch axis, or determining a relative pitch angle between the chassis structure and the load carrying body by comparing the measured pitch angles of the chassis structure and the load carrying body when the load carrying body is pivotally mounted with respect to the pivot axis being substantially parallel to the roll axis, (S4) controlling the lifting and lowering sequence at least based on the determined absolute and relative angles.

A computer-implemented method is disclosed for a vehicle comprising a vehicle body and a vehicle subsystem for load carrying, wherein the vehicle subsystem for load carrying is configured to be increasingly tilted in relation to the vehicle body for load discharge during a tipping operation of the vehicle. The method comprises (during the tipping operation) acquiring respective lateral load balance metrics for two different locations along the longitudinal dimension of the vehicle, dynamically determining a difference between the respective lateral load balance metrics, and causing a tipping interruptive action to be performed based on an increase rate of the difference.
