Stability system

A lift vehicle comprising:

• a chassis;
• a first ground engaging structure proximate a first end of the chassis and a second ground engaging structure proximate a second end of the chassis;
• wherein the chassis is supported by the first and second ground engaging structures;
• wherein the chassis comprises a propulsion system for moving the lift vehicle via the first and second ground engaging structures;
• a platform mounted to the chassis and moveable between a raised position and a lowered position with respect to the chassis;
• and
• a stability system for inhibiting tipping of the lift vehicle, the stability system comprising:
• a first body mounted to the chassis and configured to extend at least partially between the first ground engaging structure and the second ground engaging structure;
• wherein the first body is configured to be moveable relative to the chassis between a deployed position in which the first body enhances the stability of the lift vehicle if the lift vehicle is driven into a depression when the platform is in the raised position, and a stowed position when the platform is in the lowered position;
• and
• wherein when the first body is in the deployed position, the stability system is arranged to produce an output indicating that a force having at least an upward component has been exerted on the first body.
