Zusammenfassung: | A lift-truck including a support means extending from a load engagement means; a distance sensor to measure the distance (D) to the load engagement means; a control unit connected to an operator interface and a lifting/lowering unit and to the distance sensor, the distance sensor attached to the support means at a fixed distance above the load engagement means, the control unit receives start signal from the operator interface and performs a height adjustment cycle of the load engagement means comprising; determining a default distance (D0) to the surface on the load engagement means; determining the present distance (D) to the surface on the load engagement means; comparing the default distance (D0) and the present distance (D); moving the load engagement means a distance (R) when a difference (Ddelta) between the default distance (D0) and the present distance (D) is determined, the distance (R) depends on the difference (Ddelta). |
