Abstract

Offenbart ist ein Prospekt- oder Konterzug, bei dem eine Last über zumindest zwei Tragseile an einem Gegengewicht befestigt ist, dessen Relativposition durch eine Stelleinrichtung veränderbar ist. Die Stelleinrichtung hat ein Zugelement, das am Gegengewicht angreift und das über eine Antriebseinrichtung antreibbar ist, die kraft oder formschlüssig auf das Zugelement wirkt.

A prospectus or counter pull is disclosed in which a load is attached to a counterweight via at least two supporting cables, the relative position of which can be changed by an adjusting device. The actuating device has a pulling element which acts on the counterweight and which can be driven via a drive device which acts force or positively on the pulling element.
