R Konecranes charging crane at Raahe, Finland


by truck, rail or barge; scrap is a high- volume and mass material which makes transporting it by water particularly efficient. Speed, stability and sturdiness are extremely important criteria in unloading. ‘Interlocking pieces of the material cause extraordinary forces to be imparted to cranes and material handling machines,’ say Liebherr, who supply dockside equipment for the application. “Those strains can quickly impair the longevity of the equipment. The handling of scrap steel metal and other metals


is one of the toughest applications in industrial material handling.” Material handlers, crawler cranes and static and mobile dockyard cranes are all used, depending on the size of the port and the vessels involved. Liebherr has two material handling machines, its LH 30 M Industry Litronic and LH 60 M Industry Litronic, that are specifically designed for scrap handling. The operating weight of the former is from 26.5t to 29.1t, and its engine output 140 kW; for the latter the figures are 55t to 61t and 190 kW.


At the Alba terminal in Amsterdam


Maja Stewadoors has a Liebherr LHM550 harbour crane for scrap unloading; Koster Metalen at the port of Beverwijk, Netherlands has a LH 150 C High Rise Industry Litronic for the same purpose. And in southern Germany waste disposal contractor Schrott- und Metallhandel M, Kaatsch, one of the largest handling companies for scrap metal in the region, operates its own port facilities on the river Neckar loading scrap that arrives by rail onto barges for delivery
