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. 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 outside acceptable limits based on the at least one lateral state parameter; and generating an output if it is determined that the lateral condition of the hydraulic cylinder is outside acceptable limits.

An oscillation brake system and method is disclosed for a vehicle having front and rear vehicle sections coupled with an oscillation joint that allows rotation about an oscillation axis. The system includes front and rear brake sections rigidly coupled to the front and rear vehicle sections, respectively. The rear vehicle section has multiple degrees of freedom of movement relative to front vehicle section. When the oscillation brake is activated the front brake section engages the rear brake section to increase resistance against or prevent rotation about the oscillation axis. The system can also include sensors, and a controller that activates the system based on the sensor readings. The sensors can include accelerometers, pressure, position, speed or other sensors. The oscillation brake can include a hub splined to separator plates and a housing splined to friction plates, where the oscillation brake is activated to force the separator and friction plates together.

A rollover prevention system for a machine is disclosed. The rollover prevention system may include an inertial measurement unit (IMU) configured to detect a discharge event of a payload material from the machine and measure a body angle of the machine. The rollover prevention system may further include a controller in communication with the IMU. The controller may be configured to determine an angle of repose of the machine based on the detected discharge event and the measured body angle.

A system for and method of operating a tipper comprising a tipper body pivotably movable with respect to a frame with a hydraulic cylinder disposed therebetween and actuatable to pivot the tipper body. A loading parameter relating to the load through the hydraulic cylinder is monitored during tipping. Based on at least the loading parameter, it is determined whether the hydraulic cylinder is at risk of buckling and, if it is determined that the hydraulic cylinder is at risk of buckling, an output is generated in response.

There is disclosed a method of determining the mass of a load in a tipper body of a tipper, the 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. The method comprises receiving at least one pressure parameter relating to the hydraulic pressure within the hydraulic cylinder at an angular position of the tipper body and at least one angular positional parameter relating to the angular position of the tipper body at the said angular position; and determining a mass parameter relating to the mass of a load in the tipper body based on at least the at least one pressure parameter and the at least one angular positional parameter

A method for implementing and canceling an automatic operation of a body of a machine includes receiving a selection of an automatic setting according to a first operation of a hoist mode actuator, determining an activation state of the automatic setting, causing an automatic operation of an engine of the machine to adjust an idle level of the engine and an automatic operation of a hoist system to move the body in a first direction to a first position. The method includes canceling the automatic operation of the engine and the automatic operation of the hoist system and controlling the idle level of the engine according to operations of a throttle, the hoist system to move the body according to the idle level of the engine and respective directions of the second operation the hoist mode actuator and subsequent operations of the hoist mode actuator.

An overload protection control system and method are disclosed for an articulated dump truck having a load bin movable between loaded and unloaded positions by hydraulic cylinders of a hydraulic circuit. The overload protection control system includes a source of load data associated with the load bin. The overload protection system also includes at least one controller that receives and processes the load data to determine an overload condition associated with the load bin and determines a speed associated with the work vehicle. The speed is reduced in the overload condition.

A method for implementing an operation of a body of a machine includes receiving data indicating an operation of a positioning mode actuator to facilitate movement of the body from a first position, determining activation state of a multi-auto mode to actuate a first auto lower mode to operate a hoist system to lower the body automatically and a first auto raise mode to operate the hoist system to raise the body automatically. The method includes determining the first auto lower mode is selected according to the data indicating the operation of the positioning mode actuator, and causing a hoist system to actively lower the body from the first position to a second position and passively lower the body from the second position to a third position, independent of the activation state of the multi-auto mode.

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.
