The invention relates to a traction arrangement configured for driving a belt, to a method for driving a belt and to the use of the traction arrangement in at least one of the following applications: in a crane, in a plotter, for driving a steel cable, a rope, a chain and a ball path. The traction arrangement (1) comprises a first guideway (3) and a second guideway (4), wherein each guideway (3, 4) is fixed to mounting means (5), wherein the first and the second guide- way (3, 4) are spaced parallel on a surface of the traction arrangement (1), a slide (6) movable on the surface and configured for spanning the surface through a lateral motion along a first axis, wherein the slide (6) is arranged essentially perpendicular to the first and the sec¬ ond guideway (3, 4), a jack (7) connected to the slide (6), wherein the jack (7) is movable along the slide (6) through a lateral motion along a second axis, the second axis being perpendicular to the first axis, and a first motor (8) for driving a first belt (2), wherein the first motor (8) is rotatably arranged and controls traction of the first belt (2) such that when the first motor (8) rotates in counterclockwise direction or in clockwise direction, the jack (7) moves along the second axis such that a second position coordinate of the jack (7) along the second axis is adjustable. In this way, a possibility for driving a belt is provided that is simple, accurate, requires no adjustment in action, in which no cable spans have to be dragged and an unwanted diagonal motion of a slide is suppressed. |
