Abstract: We generally describe a winch (100) comprising: a plurality of ropes (130, 140) coupleable to a first load (200) or to different respective second loads (200, 210); a support frame (110); and a first roller (150) moveably coupled to the support frame (110), wherein a first rope (150) of the plurality of ropes (130, 140) is moveable over the first roller (150); wherein a movement of the first roller (150) is configured to shorten and/or lengthen a usable length of the first rope (140) of the plurality of ropes (130, 140), and wherein the shortening and/or lengthening of the usable length of the first rope (140) is configured to raise and/or lower the first load (200) or one of the second loads (200, 210) to which the first roller (150) is coupleable via the first rope (140).

Abstract: A winch includes a first electrically conductive cable for transferring electrical power and/or electrical data signals where the first electrically conductive cable is in the form of a spiral, a fixation unit coupled to a first portion of the first electrically conductive cable and configured to fix in place the first portion of the first electrically conductive cable, and a first support member coupled to a second portion of the first electrically conductive cable where the first portion and the second portion are different from each other, where the first support member is coupleable to a winch drum and is rotatable, together with the second portion of the first electrically conductive cable, with the winch drum in a rotational direction around an axis of rotation of the winch drum while the first portion of the first electrically conductive cable is fixed in place during the rotation of the winch drum.

Abstract: A winch (100, 200) includes a rope (105), an overwinding sensor (106) coupled to the rope (105) where the overwinding sensor (106) is moveable between a first position and a second position upon winding and/or unwinding of the rope (105). The overwinding sensor (106) includes a first electrically conducting member, a contact member (104) having a second electrically conducting member which is contactable by the first electrically conducting member when the overwinding sensor (106) is in the second position. The second electrically conducting member is not contactable by the first electrically conducting member when the overwinding sensor (106) is in the first position. The winch (100, 200) is configured to stop and/or prevent and/or hamper winding of the rope (105) upon establishment of an electrical contact between the first electrically conducting member and the second electrically conducting member when the overwinding sensor (106) is in the second position.

Abstract: A winch comprising one or more of an overwinding prevention unit, a load spin prevention device, a power supply board comprising substantially circular electrical contacts, a rope tension control unit, and a system comprising the winch and a load, attached to the winch, having a load battery chargeable via the winch.

Abstract: A lighting device includes a flexible lighting panel, a plurality of winches coupled at different, respective locations to the flexible lighting panel, and one or more controllers configured to control the winches to raise and/or lower the flexible lighting panel at one or more of the different, respective locations to generate a wave-like movement of the flexible lighting panel.

Abstract: A winch having a rope and a rigid member coupled, at a first end portion of the rope, to the rope. The rigid member is coupleable to a load raisable and/or lowerable by the winch, where the rigid member is configured to substantially increase an effective length of the load to stabilize the load when being raised and/or lowered by the winch.
