Weight compensation device of a lifting door with at least one compression spring

A weight compensation device for a drive of a lifting door with a door frame for position-dependent compensation of a weight force of a door leaf of the lifting door comprising a drive shaft, which is configured to be coupled to the drive in order to carry out an opening movement which raises the door leaf and a closing movement which lowers the door leaf, wherein at least one compression spring is provided and arranged such that the at least one compression spring supports the opening movement, and the compression spring is arranged in a hollow-cylindrical guide element, characterized in that the hollow-cylindrical guide element is rotatably attached to a mount for supporting a rotary motion of the drive shaft, wherein a base part at which a first end of the compression spring adjoins, and an end plate at which a second end of the compression spring adjoins, are connected to the hollow-cylindrical guide element, wherein the compression spring is supported at the base part, which is fixed with respect to the hollow-cylindrical guide element, and at an adjusting element, which is translationally movable relative to the hollow-cylindrical guide element, in a force transmitting manner, wherein the adjusting element is formed as a spindle nut, and wherein the spindle nut is coupled to a stationary shaft by a threaded engagement, wherein the stationary shaft is non-rotatably fixed to the door frame.
