Abstract: A device for moving an object is disclosed. The device has a drive cylinder with drive grooves and a set of idler pulleys. The idler pulleys are on a shaft that is parallel to the drive cylinder. Each of the idler pulleys rotate at an angle around the drive shaft that aligns the grooves of the idler pulleys to neighboring drive grooves. This allows the line to pass onto the drive groove, around an idler pulley, and onto a next adjacent drive groove. The line therefore winds back and forth between the drive grooves, the idler pulleys, and back to the next drive groove. One end of the line is placed under tension and the other is attached to an object or to a fixed member. The drive cylinder is driven and the line is moved through the device, or the device is moved along the line, respectively.

Abstract: A slider has a drum with alternating alpha and beta grooves, first stacked pulleys, and second stacked pulleys. First and second end pulleys are at opposite ends of the slider. A line wraps as a loop from the last beta groove, around the first end pulley, to the last alpha groove, back and forth around the first stacked pulleys, off the first alpha groove, around the second end pulley, to the first beta groove, back and forth around the second stacked pulleys, and back to the last beta groove. When the drum or the end pulleys are driven, the difference in circumferences of the grooves causes the slider to move toward one of the first or second end pulleys.
