    FIELD OF THE INVENTION
    The present invention relates to a work tool lifting device for raising a work tool with one or more lifting means from a working position to a moving position, for use in a variety of basic machines such as, for example, a lanyard or other similar work-driven mobile machinery, one or more of the basic machine chassis mounted on the basic machine having one or more lifting frames to which one or more work equipment is attached.
    BACKGROUND OF THE INVENTION
    A basic machine is a machine that moves and uses a implement.
    US6526677 and USRE35700E disclose a implement lifting device. US6526677 and USRE35700E disclose a lifting device in which a vertical cylinder is used to lift a working implement, the working implement being a snow plow. The lifting device of US6526677 and USRE35700E is located completely in front of the vehicle, whereby the length of the vehicle increases significantly, the large overall length of the vehicle makes it difficult to handle the vehicle in small work areas. The implement lifting device of US6526677 is secured to the underside of the vehicle by means of quick release clips. The implement lifting device of US6526677 and USRE35700E does not allow the implement to flex, so on uneven work surfaces, the implement makes poor cleaning marks, and the implement can be damaged if it collides with an obstacle.
    In the known basic machine-moving implement lifting devices, the lifting devices do not give the implement flexibility, so the implement can be damaged due to uneven machining surface.
    PURPOSE OF THE INVENTION
    The object of the invention is to combine a work-lifting device having good evasive properties and yet operating in a technically simple manner.
    The above drawbacks can be overcome and the above-mentioned purposes are achieved by the implement lifting device according to the invention, which is characterized in what is defined in the characterizing part of claim 1. Preferred embodiments of the invention are the subject of dependent claims 2 to 6.
    DESCRIPTION OF THE INVENTION
    The main advantage of the invention is that the invented implement lifting device combines good evasive properties while still being technically simple to operate. The invented implement lifting frame hoisting frame is mounted freely movable in an upward and downward direction from the base machine to the base machine, i.e. the vehicle mounted base frame, so that the hoisting frame can tilt laterally and the implement mounted to the hoisting frame can tilt sideways and thus prevent an obstacle from breaking. It is clear that the invented implement lifting device achieves significant cost savings in property management.
