Abstract: A crane having a boom and a jib swingable on the boom between a taken in position and a stretched out position includes a jib holding construction. A jib hold rod is movably mounted on the jib between a first position in which a base end of the jib hold rod is connected to the jib when the jib is in the taken in position, and a second position in which the base end of the jib hold rod is connected to a portion of the boom for supporting the jib in the stretched out position. A rod holding link is mounted to the jib for selectively holding the base end of the jib hold rod at a correct position for connection to the boom when the jib is swung out to the stretched out position. This avoids the need to manually locate the jib hold rod in the second position when the jib is stretched out.

Abstract: A jib stretching and folding device including an auxiliary connector mounted on a lower surface of a jib in the vicinity of a base end portion ofo the jib in a jib folded condition. The auxiliary connector includes a cylindrical housing fixed to the lower surface of the jib and a connecting rod rotatably supported by the housing and having an axis which is substantially parellel to the lower surface of the jib. The jib is twisted about the axis of the connecting rod to effect a jib stretching or folding operation. A twist guiding groove is formed on one of the housing and the connecting rood of the auxiliary connector, and an engagement projection is provided on the other of the housing and the connecting rod to engage the twist guiding groove. When the jib is raised or lowered by a jib raising/lowering means, the engagement projection is moved in the twist guiding groove to generate a jib twisting force. Thus, the jib is automatically twisted in the jib stretching or folding operation. Accordingly, a burden of labor of an operator in stretching and folding the jib can be reduced. Further, the operation can be made continuous to thereby improve the efficiency of the jib stretching and folding operation.

Abstract: In a crane capable of folding a strut type jib along a vertical side surface of a boom and also capable of stretching the jib from such a folded condition in a so-called twisting fashion, a jib stretching and folding device includes a twist shaft for jib stretching and folding operation located below a lower member of the jib under the jib folded condition, so as to fold the jib at an upper position aside the boom. Furthermore, the twist shaft is movable toward and away from the forward end of the boom, so as to fold the jib at a position shifted to the base end of the boom. The advance condition of the twist shaft to the forward end of the boom can be fixed so as to prevent movement of the jib to the forward end of the boom.
