Patent number: 11167962Abstract: A crane having an undercarriage, a superstructure pivotable about a slewing axis relative to the undercarriage, a counterweight unit and a counterweight adjustment device. The counterweight adjustment device includes a telescopic frame which is fastened to the superstructure and has a telescopic longitudinal member, a counterweight unit arranged to be displaceable along the frame, a drive unit for displacing the counterweight unit and a kinematic unit to telescope the frame in a driven manner. A jetty is fastened to a rear end, remote from the slewing axis, of the longitudinal member, the counterweight unit is displaceable along the frame in the region of the superstructure as far as the jetty, the counterweight unit is able to be fastened to the jetty and the counterweight unit is able to be telescoped in and out on the jetty with the frame.Type: GrantFiled: July 5, 2017Date of Patent: November 9, 2021Assignee: Tadano Demag GmbHInventors: Alfons Weckbecker, Martin Zwifka, Thorsten Helwes, Fritz-Botho Köster
