A slope mower includes a mower body, drive wheels, left and right mower decks and left and right support wheels mounted on support arms pivotally mounted to the mower body with hydraulic actuators acting on the left and right support arms to maintain the mower body vertical. An inclinometer measures the tilt angle of the mower body and a controller reads the angle and controls a leveling valve to supply hydraulic fluid from a supply line to the leveling actuator toward which the inclinometer indicates the mower body is leaning to move the mower body back to vertical. The system can be programmed to actuate a leveling actuator only when the detected tilt angle exceeds a minimum angle. Lockout valves can be actuated by the controller to block the flow of hydraulic fluid to or from both actuators if a maximum allowed tilt angle is exceeded.

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.

The present disclosure relates to a method for controlling a lifting and lowering sequence of a load carrying body (20) of a vehicle (1) and to a vehicle comprising a chassis structure (10) and the load carrying body (20) pivotally mounted on the chassis structure (10) with respect to a pivot axis being substantially parallel to either a pitch axis (Y) or a roll axis (X) of the vehicle, wherein the vehicle (1) comprises sensing means (11) provided on the chassis structure for measuring roll angle and pitch angle of the chassis structure and sensing means (21) provided on the load carrying body for measuring roll angle and pitch angle of the load carrying body. 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 dump trailer support assembly for supporting a belly dump trailer when the belly dump trailer is not coupled to a tractor includes a box for positioning on a support surface beneath a belly dump trailer. A shaft is slidably integrated into the box such that the shaft can be slid upwardly or downwardly in the box. A support is coupled to the shaft for supporting a bottom of the belly dump trailer when the belly dump trailer is not attached to a tractor. Additionally, the support is comprised of a magnetized material to magnetically engage the bottom of the belly dump trailer and inhibit the belly dump trailer from sliding on the support.

A cabin control valve assembly for a vehicle includes a cabin control valve with at least one port P, and at least one solenoid direction control valve that is integrated with the cabin control valve at the at least one port P such that pressurised air that enters through an inlet port of the cabin control valve reaches an inlet of the at least one solenoid direction control valve. The at least one solenoid direction control valve is configured to allow, based on at least one signal indicative of at least one parameter related to the vehicle, delivery of pressurised air to a corresponding cylinder coupled to the cabin control valve assembly for operation of the cylinder.

This safety device for a tipper truck comprises proximity sensors and is configured to switch to a triggered state when a foreign body is detected within a predetermined distance around the tipper truck by at least one of the proximity sensors. The tipper truck comprises a bucket and a lifting device, which is powered by a power source and which is configured to move the bucket between a lowered position and a raised position. For improved safety, the safety device comprises cut-off means configured to cut-off the lifting device from the power source when the bucket is in the lowered position and when the safety device is in the triggered state.

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.

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.

A self-leveling single axle dump truck is provided, the truck comprising a frame, a dump body pivotably mounted on the frame, and a propulsion and self-leveling system comprising a single axle supporting the frame at least during motion of the self-leveling single axle dump truck, the single axle comprising at least a first and a second wheel and at least a first electric traction motor for driving the first wheel and a second electric traction motor for driving the second wheel.
