Casting crane no. 22 has been revised in the factory of Mercon in Gorinchem. This casting crane, with a lifting capacity of 460 tonnes, consists of four large welded box sections where trolleys run over. The corners where these trolleys have run, were constructively worn and needed replacing. First, the existing rails have been removed, and the angle was burned out of the tube under the rails. Completely new angles (3/4 HE1000L profile) were then welded over the entire length in the tubular sections, and also the compound of the partitions in the box profiles were welded back together and placed in the appropriate sheer. Thereafter, the beam is provided with new cabling and made ready for transport.
