New generation Demag V -type crane

V-type girders weigh, on average, 17% less than comparable box-section profile girders. This reduced crane deadweight produces less wheel pressure, minimising the forces transmitted to the existing building structure and increasing the maximum load capacity.

Consequently, the new Demag V-type crane provides architects with greater freedom in planning new factory buildings. The design is also suitable for companies, who wish to employ additional lifting equipment in existing assembly and production bays.

The patent pending design, which features diaphragm joints, also cuts oscillation of the crane girder by up to 30%. The reduced oscillation characteristics cause lower loads to be transmitted to the crane, its components and the building structure, doubling the service life of the crane to more than 500,000 load changes. 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,” explains 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. Its special design allows sensitive loads to be transported safely and precisely for indoor and outdoor applications. We are now well placed to meet our customers‘ specific load handling requirements, boost productivity and improve operating safety.”

The new single girder Demag V-type crane may be used for various crane types, including overhead travelling cranes, suspension cranes, portal cranes and wall mounted travelling cranes.
