Abstract: Expandable heavy equipment 1, comprising a first frame element 5, a connector 11, at least one elongated pull element 14, and further frame elements 7. The pull element 14 is connected to the first frame element 5 with a first coupler 31 and to one 9 of the further frame elements 7 with a second coupler 35. The pull element 14 is in a folded state in a transport condition and in an extended state in a working condition. The pull element 14 comprises load bearing fibers/fibres 141 extending from the first coupler 31 to the second coupler 35. The pull element 14 comprises at least one flexible part 43 and at least two stiff parts 45. The flexible part 43 has a lower bending stiffness than the two stiff parts 45 and enables the pull element 14 to be arranged in the folded state.

Abstract: An elongated pull element (14), in particular for an element of an expandable heavy equipment (1) comprises a bundle of load bearing fibers/fibres (41) extending along the length of the elongated pull element (14), and stiffening means (54) comprising an exoskeleton for increasing the bending stiffness of the elongated pull element (14), compared to the bending stiffness of the load bearing fibers/fibres (41).

Abstract: A device 100 produces an endless winding cable 101 by winding a yarn 106 around two thimbles 102, 104. The device 100 comprises an elongated guide 110, a carriage 112, a yarn feeder 114, a first thimble holder 116, and a second thimble holder 118. The first thimble holder 116 and the second thimble holder 118 each hold one of the two thimbles 102, 104. The carriage 112 is movable relative to the elongated guide 110. The yarn feeder 114 is connected to the carriage 112, and comprises at least one spool holder 120 for holding a spool 122 with the at least one yarn 106, and an output guide 124 for guiding the at least one yarn 106 to the cable during winding. The yarn feeder 114 comprises at least one yarn brake 126 for controlling a tension of the at least one yarn 106 during winding.

Abstract: A cable comprises a first and a second thimble (2, 4), and at least one main yarn (6) and an auxiliary yarn (7). The first and the second thimble are provided at opposite ends of the cable. The at least one main yarn (6) and the auxiliary yarn (7) each forms turns around the first and second thimble (2, 4). Each thimble (2, 4) comprises a bearing surface (40), and holds a stack (19) of layers (10) of turns of the main yarn (6). A stack (119) of turns of the auxiliary yarn (7) comprising at least a first layer (13) of turns of the auxiliary yarn (7) lies on the bearing surface (40) of the respective thimble (2, 4).

Abstract: A cable 1 comprises a first thimble 2 and a second thimble 4, at least one yarn 6, and at least a first conductive fiber 8 for monitoring the cable 1. The yarn 6 extends from the first thimble 2 to the second thimble 4, turns around the second thimble 4, extends from the second thimble 4 to the first thimble 2, and turns around the first thimble 2. Each thimble holds a stack 9 of layers 10 of turns of the yarn 6. The first conductive fiber 8 is designed to signal the wear of the yarn 6 by breaking after a predetermined portion of the turns of the yarn 6 breaks. The first conductive fiber 8 is positioned at the first thimble 2 between the turns of the yarn 6 at less than 50% of the stack height h.
