Patent number: 7648324Abstract: In a loading platform system for mounting on vehicles, particularly trucks, comprising at least one lift support arrangement consisting of two essentially parallel spaced support structures, an essentially plate-like loading platform for lifting and lowering a load, at least one lift actuator for lifting and lowering the loading platform and a slide unit, which is movable back and forth in the longitudinal direction of the vehicle and mountable on the vehicle and on which at least the lift support arrangement, the loading platform and the lift actuator are mounted. The slide unit is adapted to be mounted on the support frame of the vehicle by transverse frame members, which are fitted to the spacing of the vehicle support frame members and include means at their ends for mounting them to the vehicle support frame members.Type: GrantFiled: June 9, 2000Date of Patent: January 19, 2010Assignee: Sürensen Hydraulik, Zweigniederlassung, Ulfborg, Filialaf Sörensen Hydraulik GmbHInventor: Jens Herman Jensen

Patent number: 6748893Abstract: There is disclosed a foil system for hydrofoil vessels, where the foil system lifts and carries the total weight of the craft at speed, and comprising a number of adjustable control fins/-surfaces (3-5), supporting legs (7-9) between the foil system and the hull of the vessel, and means to adjust the control fins/-surfaces. The foil system is characterized in that it is formed by one single approximately horizontal foil body comprising two generally mirror symmetric foil arms (1, 2) which extend aft to each side in almost equal angle, in that the forward corner of the angle lies in the center line (11) of the craft, and the foil arms extend aft to each side in an almost equal angle (12) with the longitudinal centerline (11) of the craft.Type: GrantFiled: August 27, 2001Date of Patent: June 15, 2004Inventors: Jens-Herman Jorde, Jan Ingar Norheim
