Abstract

14 A system for a vertically adjustable tower crane enables a crane to be efficiently raised during a working day above a maximum night or low visibility altitude and then lowered at the end of the day back below the maximum night or low visibility altitude. The system comprises: a base support extending 5 outward from an external face of a building; a static tower connected to the base support; a climbing tower connected to the static tower; and a climbing mechanism attached to the climbing tower or the static tower, whereby the climbing tower can be moved up or down relative to the static tower. 10 20 19 20 12 99 2 5 Fe b 20 19 2019201299 25 Feb 2019 10 14
