Crane System Supplied For Production Development

Published:  22 June, 2009


Materials handling specialist, Demag Cranes & Components Ltd, has supplied four crane systems to Composite Metal Flooring Ltd (CMF), as part of the development of a new production facility.


The Monmouthshire based company manufactures metal floor decking products and associated metal flashings, under the MetFloor brand name, for use in the fast track construction industry. The development of the new factory was prompted by the need to secure the supply chain for sister companies within the Studwelders' group.


CMF"s 30,000ft2 production facility is co-located with 8,500ft2 of office space. The factory comprises three independent, automated, CNC controlled production lines, which are dedicated to the manufacture of different floor deck profiles. The manufacturing process involves loading coils of galvanised steel, weighing up to 8 tonnes, onto de-coilers. The steel is then fed through a cold roll forming machine and guillotined to length, before being stamped with component details and bundled into batches for despatch.

To meet the specific materials handling requirements of the production process, Demag supplied four single girder cranes, all of which have a span of 19m and are rated at 10 tonnes SWL. The cranes feature anti collision protection, cross travel and long travel limits and are operated by radio remote control. Demag DR PRO wire rope hoists are mounted on all four of the crane girders. The cranes have a long travel speed of 40/10 m per minute, a cross travel speed of 5/30 m per minute and a lifting speed of 5/0.8 m per minute.
