There is disclosed a method of generating an alert relating to a hydraulic actuation system for actuating a hydraulic cylinder, the hydraulic control system comprising a hydraulic fluid tank and a hydraulic fluid filter. The method comprises monitoring the pressure drop over the hydraulic fluid filter; determining a rate of change characteristic relating to the rate of change of pressure drop over at least one time period in which there is a hydraulic fluid flow through the hydraulic fluid filter; determining whether the hydraulic fluid is dirty based on at least the rate of change characteristic; and generating an alert if it is determined that the hydraulic fluid is dirty.

There is disclosed a method of determining the mass of a load in a tipper body of a tipper, the tipper includes 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 includes 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 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.

There is disclosed a method of generating a service indicator for 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 to perform a tipping cycle. The method comprises monitoring at least one parameter relating to the movement of the tipper body with respect to the frame; identifying when a tipping cycle is performed based on the at least one monitored parameter; counting the number of tipping cycles performed; determining whether the number of tipping cycles performed has reached a service threshold; and generating a service indicator when it is determined that the service threshold has been reached.

There is disclosed a method of operating a tipper vehicle, the tipper vehicle 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 monitoring at least one of (i) a pressure parameter relating to the hydraulic pressure within the hydraulic cylinder and (ii) an angular positional parameter relating to the angular position of the tipper body; determining a maximum permissible vehicle speed based on at least one of the monitored (i) pressure parameter and (ii) angular positional parameter; and displaying the maximum permissible vehicle speed.
