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.
Claims19
A weight compensation device for a drive of a lifting door for position-dependent compensation of a 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 the compression spring supports the opening movement, and the compression spring is arranged in a stationary hollow-cylindrical guide element, characterized in that the stationary hollow-cylindrical guide element is attached to a mount in a torque-proof manner for supporting a rotary motion of the force transmission unit.
