Calabrian crawler
01 May 2008
As part of the construction of a new ferry harbour in the town of Palmi, Calabria, in southwest Italy, contractor Franco Guiseppe di Roccella Ionica is using a Liebherr HS 895 HD crawler crane to place the large stone and concrete blocks needed to form the breakwater.
The company decided to carry out the work from the quayside without the use of barges. This allows work to continue if there are rough seas, which is impossible with barges, and allows greater precision and productivity when moving and positioning material.
The 200 tonne class Liebherr crane is being used to place the concrete and natural stone blocks, some of which are as large as 11 m3, at a working radius of up to 30 m. The lifting and positioning the blocks is carried out with a hydraulic grapple, which is controlled by the simultaneous operation of grab and hoist winches. Each winch has a line pull of 35 tonnes.
