The Grove GTK1100 telescopic tower crane, unveiled at Bauma, has completed its inaugural lift at a jobsite in Germany, following an extensive test programme at the manufacturers Wilhelmshavenplant.
The first unit was delivered in the past few weeks to Wiesbauer, the Bietigheim-Bissingen based crane rental company that helped develop the GTK.
The GTK1100's first job was in Ilshofen, Baden Würtemberg, southern Germanywhere it was used to install a 2KW wind turbine in a field for Repower Systems. The crane is designed to travel on four or five trailers depending on its configuration and local road regulations. The Ilshofen job did not require additional counterweight so its was delivered on four trailers.
