Abstract
The invention relates to a weight compensation device for a drive of a lifting door, for the position-dependent compensation of the weight force of a door leaf of the lifting door, with a force transmission unit which can 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 which is arranged in such a way that it supports the opening movement. The invention also relates to a lifting door, in particular an industrial lifting door, which has a door leaf, with a drive, such as a motor, and with a weight compensation device according to the invention.

Weight compensation device for a drive of a lifting door for position-dependent compensation of the weight force of a door leaf of the lifting door, with a force transmission unit, such as a drive shaft, which may 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 it 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 attached to a mount in a torque-proof manner for supporting a rotary motion of the force transmission device.
