Demag V-type cranes help save re­sources

Project Monitor - - FRONT PAGE -

Terex Ma­te­rial Han­dling has launched a new gen­er­a­tion of cranes set­ting a new stan­dard in the in­dus­try with its Demag V-type crane, which uses less ma­te­rial and helps to save re­sources. The V-type girder weighs on av­er­age 17 per cent less than com­pa­ra­ble box-sec­tion pro­file gird­ers. The re­duced crane dead­weight pro­duces less wheel pres­sure, min­imises the forces trans­mit­ted to the ex­ist­ing build­ing struc­ture and in­creases the max­i­mum load ca­pac­ity. Con­se­quently, the new Demag V-type crane gives ar­chi­tects greater free­dom for plan­ning new fac­tory build­ings and is also suit­able for com­pa­nies that want to em­ploy it in ex­ist­ing assem­bly and pro­duc­tion bays.

The de­sign (patent pend­ing), which fea­tures di­aphragm joints, also cuts os­cil­la­tion of the crane girder by up to 30 per cent. The re­duced os­cil­la­tion char­ac­ter­is­tics cause lower loads to be trans­mit­ted to the crane and its com­po­nents, as well as to the en­tire build­ing, and dou­ble the ser­vice life of the crane to more than 500,000 changes of load. In ad­di­tion, the im­proved os­cil­la­tion char­ac­ter­is­tics en­able heavy and sen­si­tive loads, such as glass pan­els, flu­ids or alu­minium shell sec­tions for air­craft, to be po­si­tioned more pre­cisely and quickly.

“The new V-type girder is the re­sult of our con­tin­u­ous de­vel­op­ment in the crane en­gi­neer­ing sec­tor,” ex­plained An­dreas Hambrock, Head of the Univer­sal Cranes Business Line at Terex Ma­te­rial Han­dling. “The new crane is an ideal sup­ple­ment to our ex­ist­ing range of rolled and box-sec­tion gird­ers. Thanks to its spe­cial de­sign, sen­si­tive loads can also be trans­ported safely and pre­cisely in­doors and in out­door ap­pli­ca­tions.”

The new Demag V-type girder is ini­tially avail­able as a sin­gle-girder crane on the Ger­man mar­ket. It can be em­ployed for var­i­ous crane types, such as over­head trav­el­ling cranes, sus­pen­sion cranes, por­tal cranes or wall-mounted trav­el­ling cranes.
