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.

Abstract: A lifting fitting for lifting a series of elements of different sizes in a wind turbine is proposed. The lifting fitting has a base plate having at least one central slotted hole shaped to accommodate a fastener for fastening the lifting fitting to an element to be lifted, at least two outer slotted holes each shaped to accommodate a further fastener for fastening the lifting fitting to an element to be lifted. The outer slotted holes are arranged transverse to the central slotted hole. The lifting fitting is connected to a lifting apparatus for lifting the element. A method of assembling the series of elements is proposed. The elements are successively lifted into place. The lifting fitting can be used in the assembly of a wind turbine tower having individually liftable tower sections for lifting the tower sections into place.

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.
