Abstract (en)
The suspension arrangement of a blade (4) of an underbody grader (21) used in a vehicle, work machine or similar comprises:- turning devices (5) for turning the blade (4) from the working position (I) to the transport position (II) and back; and- transfer devices (6, 7, 9, 14), which have been arranged∘ to reduce the delivery angle of the blade before the blade (4) is turned from the working position (I) to the transport position (II) or at the same time as when the blade (4) is being turned from the working position (I) to the transport position (II), and∘ to increase the delivery angle of the blade after the blade (4) has been turned from the transport position (II) to the working position (I) or at the same time as when the blade (4) is being turned from the transport position (II) to the working position (I).The transfer devices (6, 7, 14) have been adapted to transfer the turning joint (14) of the blade (4) to the first lateral direction, in which case the blade (4) rotates with respect to one joint (9) reducing the delivery angle, and to a second lateral direction, in which case the blade (4) rotates with respect to a second joint (9) increasing the delivery angle.The room for movement of the transferable turning joint (14) has been implemented in a form-restricted member (7).Also a parallel independent claim for a vehicle, work machine or similar.
