Liebherr has launched is new 85 EC-B 5 FR.tronic flat top tower crane at the 2011 Smopyc trade fair in Zaragoza.
Maximum load capacity is 5000 kg with1300 kg at the jib end and a maximum working radius of 50 metres. All loads are lifted in the double-reeved mode.
The new city crane’s development included the low-width 85 LC tower system which has new pin connectors and measures 1.2 x 1.2 metres simplifying both transportation and erecting work if the inner-city site is small or access is difficult. The cruciform base measures only 3.0 x 3.0 metres.
The complete slewing section of the new crane - ready for a maximum working radius of 50 metres - can travel on just two semi-trailer trucks. The heaviest individual element weighs less than 3 tonnes and can be lifted by a 60 tonne truck crane.
The new 85 LC tower system consists of 11.7, 5.85 or 3.9 metre tower sections with a tower base element 12.0 metres long. The 3.9 metre long climbing tower section can be used inside or outside the building and can be installed in an elevator shaft where necessary. The standard equipment 24 kW frequency converter hoist gear permits lifting heights up to 260 metres. The maximum free-standing height under the hook is 46.2 metres.
