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 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 method for determining stability of a vehicle having a load suspended from the vehicle is provided. The method can include obtaining measurements from a plurality of sensors positioned on the vehicle, obtaining a measurement from a vehicle accelerometer operative to determine an inclination of the vehicle, determining a position of the load suspended from the vehicle, determining a slung load of the load suspended from the vehicle, using the determined slung load and the determined position of the load suspended from the vehicle, determining tipping moments acting on the vehicle, determining righting moments acting on the vehicle and determining a tipping stability based on the determined tipping moments and determined righting moments.

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 which can be actuated by a hydraulic actuation system to pivot the tipper body. The method comprises receiving at least one lateral state parameter relating to at least one lateral state of the hydraulic cylinder; determining whether the lateral condition of the hydraulic cylinder is within acceptable limits based on the at least one lateral state parameter; and altering, or permitting the alteration of, at least one operational parameter of the hydraulic actuation system if it is determined that the lateral condition of the hydraulic cylinder is within acceptable limits.

The present invention relates to a construction machine having at least one material receiver that is adjustable by means of at least one hydraulic actuator for unloading, with the required feed pressure for the actuator actuation being able to be provided by a hydraulic circuit of the construction machine and with the feed pressure being able to be limited to a limit pressure by means of at least one pressure limiting device, wherein the construction machine comprises a weighing system for determining the current load weight of the material receiver; and a control for the hydraulic circuit is provided that adapts the limit pressure of the pressure limiting device in dependence on the determined load weight.

A work vehicle periphery monitoring system which monitors a periphery of a work vehicle with a vessel for loading a load thereon, the work vehicle periphery monitoring system includes: a plurality of object detecting devices each of which is attached to the work vehicle and detects an object existing around the work vehicle; and a controller which notifies an alarm based on a detection result of the object detecting device and switches between a notification mode for notifying the alarm and a restriction mode for restricting the notification of the alarm based on a state of the work vehicle.

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 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.

A trailer tipper features multi-use tilt sensors for automating leveling and tipping operations. In an example, a computerized method for controlling operation of a trailer tipper is disclosed. The trailer tipper includes a frame at least partially supported relative to a ground surface by a set of outriggers. The trailer tipper further includes a tipping platform that is rotatable relative to the frame about a hinge axis. The computerized method includes a plurality of operations that may be used to at least partially automate leveling and tipping operations.

Described are system and methods in which the speed of a service vehicle and the configuration of an extendable service component of the vehicle may be monitored. The vehicle can be driven with the extendable service component out of its home configuration as long as the speed is below a speed threshold. However, if the speed of the vehicle exceeds the speed threshold while the extendable service component is out of its home configuration, an extended service component alert signal is transmitted. Although a local alarm may (also) be provided to the vehicle operator, the extended service component alert signal is transmitted wirelessly and provides one or more alerts on at least one receiver remote from the vehicle, such as on a mobile phone of a supervisor who can take action. In some embodiments, the speed threshold may vary depending on the location of the vehicle.
