DEMAG CRANE SYSTEM optimises packaging board manufacture
A Demag double girder overhead travelling process crane installed by Terex Material Handling at Iggesund Paperboard is ensuring maximum availability along with increased productivity
T
erex Material handling has installed a Demag double girder overhead
travelling process crane at the Iggesund Paperboard (Workington) production facility in Cumbria. Part of the Swedish Holmen Group, Iggesund manufactures high quality folding box board products which are used for the premium packaging and graphics markets. The crane installation was part of an
investment in new and upgraded board production facilities to increase output by 20,000 tonnes per year. The crane was required due to the increased size and weight of the rolls in the new equipment.
MAXIMUM AVAILABILITY AND RELIABILITY With the Iggesund production line operating 24 hours a day for 365 days per year with a reel of board coming off the production line every 30 minutes, maximum availability and reliability of the material handling system is fundamental to the efficiency of the plant. To meet the specific requirements of Iggesund’s production processes Demag engineers designed a complex reel handing crane with a range of application focused features.

The solution was a 60 t SWL, 20.4 m
span crane equipped with multiple hoists consisting of two outer 35 t SWL open winch crabs and a central 60 t open winch crab. A 52 t SWL power slew lifting beam suspended from either the central hoist or the two outer hoists is required
Demag engineers designed a complex reel handing crane with a range of application focused features
to lift reels of paperboard and can be lifted by either the 2 x 35t hoists or the 60t hoist. This solution gives operational
flexibility and back-up lifting capacity in the event of a hoist failure. In addition, each crab is fitted with an auxiliary
