摘要

The catchment device has at least one support surface near the one side of a vertically running holder rail, and on the opposite side of the holder rail is a clamp eccentric rotatable on an axis of the catchment device. A vertically running counterweight is connected via a rope over a guide roller with the clamp eccentric and at the same time via a spring with the door plate. The support surface of the catchment device is held by sprung support rollers at a specific distance from the holder rails. The catchment device is suspended on the axis of the lowermost guide roller of the door plate. USE/ADVANTAGE - To prevent a lifting door or gate from falling.
