  • Apparatus for automatically levelling a base
    Patent number: 4572527
    Abstract: An apparatus for levelling a base comprises two switches (T, L) arranged to sense the disposition of a caravan or trailer base (10) in mutually perpendicular directions. According to the state of each of the switches, jacks disposed at each of the corners (11-14) of the base are actuated to alter the height of the respective corner. Further switches (SM1-SM4) are actuated when a corner of the base (10) is at a desired height to prevent further movement of the associated jack, and to cause movement of one or more other jack to level the base. Operation of the jacks in response to the switches is controlled by a control unit.
