Spira Baugeräte und Schalungslogistik, based in Speyer Germany, added a new Potain MDT 569 to its rental fleet of 60 self-erecting and 50 top-slewing cranes. The formwork and construction equipment rental company has deployed the tower crane, which has a maximum capacity of 25 t and 4.2 t at the end of the 80 m jib, to help construct a new laboratory at the Karlsruhe Institute of Technology (KIT). Spira technicians worked with two Potain factory technicians to assemble and erect the crane in two days, using a 400 t six-axle Grove GMK6400 mobile crane.
For the KIT project, the MDT 569 was erected to a hook height of 48.9 m and equipped with a 60 m jib from which it can lift 8.9 t at the end. The customer’s requirements included being able to lift elements from 15 t at 35 m and 8 t at 60 m. The crane will remain on site for 17 months where it will handle large, prefabricated components to construct two buildings – one with six floors and the other with two floors.
The Potain MDT 569 is available in three versions 20 t, 25 t and 32 t.
