  • Patent number: 10259690
    Abstract: A C-gripper for arranging at a cross-member or at a suspension element and a cross-member having at least one such C-gripper for for handling a load, formed from an upper strut, a vertical strut and a support strut which forms a so-called hook base, onto which the load can be placed. The upper strut and the vertical strut are, as with conventional constructions, rigidly connected to one another and substantially arranged at right angles to one another. Other angles likewise lie within the framework of the invention. However, the support strut is not rigid, but rather connected in a rotatably mounted manner to the vertical strut and, indeed, in such a manner that a clear dimension (h) of a mouth of the C-gripper can be modified, that is to say can be increased or decreased. Moreover, the vertical strut is telescopable. It is thus configured as a telescopic strut.

  • Patent number: 8636312
    Abstract: A C-hook for lifting heavy coils, such as coils of steel, includes a lifting frame which has an upper arm that is formed with a lifting point in the form of integrally formed lug for receiving a lifting hook of a crane. A counterweight is fixed at a forward end of the upper arm. The lower end of the frame is formed with a slide that receives a slideable load support member in the form of foot. The foot has a forward front foot end for penetration of the lumen of a coil to be lifted. The opposite, rearward end of the foot is mechanically interlinked by a mechanical linkage to a coil backstop member. The mechanical linkage includes a lever arm, which pivots about a fixed pivot point that is fast with the frame. The foot and backstop member facilitate the balanced transportation of steel coils of varying widths.
