Zusammenfassung: | A lift-truck (100) comprising:
- a load engagement means (1) arranged to be moved by a lifting/lowering unit (50);
- a support means (10) extending from the load engagement means (1);
- a distance sensor (40) directed towards the load engagement means (1) and configured to measure the distance (D) to a surface (4, 50) on the load engagement means (1);
- a control unit (51) connected to an operator interface (52) and to the lifting/lowering unit (50) and to the distance sensor (40), wherein;
- the distance sensor (40) is attached to the support means (10) at a fixed distance above the load engagement means (1), wherein
- the control unit (51) is configured to receive a start signal from the operator interface (52) and in response thereto performing a height adjustment cycle of the load engagement means (1) comprising;
- determining a default distance (D 0 ) to the surface (4, 60) on the load engagement means (1);
- determining the present distance (D) to the surface (4, 60) on the load engagement means (1);
- comparing the default distance (D 0 ) and the present distance (D);
- moving the load engagement means (1) a distance (R) when a difference (D delta ) between the default distance (D 0 ) and the present distance (D) is determined, wherein the distance (R) depends on the difference (D delta ). |
