摘要：A first measuring device in the truck (1) is used to determine the angle of rotation for the lifting frame (3) with respect to the truck frame, by measuring the rotation angle for the hinge axle via which the lifting frame is connected to the truck frame. A second measuring device determines the angle of rotation for a second rotation axle chosen from the rotation axle connecting the lifting frame to the quick-fit coupling for the work tool, or one of the rotation axles belonging to the z-kinematics mechanism. The lifting frame for the work tool is joined at one end to the truck frame via a hinge or tilt axle, and at the opposite end via a rotation axle and fasteners such as quick-fit couplings to a work tool such as a scoop, pallet fork, excavator bucket or lifting fork. The couplings are hydraulically operated by a so-called z-kinematics or z-transfer mechanism comprising a reverse tilt fitting and a hydraulic cylinder. The middle part of the reverse tilt fitting is pivotally joined to the lifting frame, and one end of this fitting is joined to one end of the hydraulic cylinder, the opposite end of the cylinder is pivotally joined to the truck frame. The opposite end of the reverse tilt fitting is pivotally joined to one end of a traction rod, itself pivotally connected to the quick-fit coupling. An Independent claim is also included for a lifting method carried out using the above construction.
