The GTK1100 revolutionizes lifting technology to raise loads of more than 70 t (77 USt) to more than 120 m ( 394 ft) with lower operating costs and minimal space requirements compared to existing lift solutions.
GTK1100 was first announced by Manitowoc Crane group during 2006 fall and the first unit was built at the company’s factory in Wilhelmshaven, Germany. The crane was shown in iron for the first time in late March 2007 at a customer day event at the Wilhelmshaven factory on the north coast of Germany.

The 110-tonne mobile tower crane consists of a wheeled carrier, a 6meterses 5-section TWIN-LOCK boom. The luffing telescopic boom, both connected by an 81 metres 6-section telescopic mast. Four spreaders at the top of the mast are attached to the outriggers at the base to provide better stability.
The GTK cranes have a self-erecting telescopic tower, mounted on an SPMT-style carrier, supporting the superstructure of an all-terrain crane, to allow for rapid set-up and lifting of heavy loads like nacelles.
Optimal For Wind Turbines Erection And City Center Sites
The patented design of GTK1100 is possible to lift the heavy load at sites which setup space is restricted. While another major advantage that GTK1100 can be only be transported using a maximum of five trailers.
Wiesbauer Helped In the Development of GTK1100
The Bietigheim-Bissingen based crane rental company has been involved in the development of the GTK1100 and the first job was in Ilshofen, Baden Wurttemberg, southern Germany where 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 it was delivered on four trailers. 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 it was delivered on four trailers. The contract was completed with five lifts, the first three being the tower mast sections that weighed 62 tonnes, 53 tonnes and 45 tonnes respectively.
CPIE Become First GTK1100 owner in Asia
China Power Equipment Installation Engineering Co (CPIE) has taken delivery of the first unit of GTK1100 in Asia in June 2009 and subsequently sent it to Inner Mongolia for installation of two 1.5MW windmills in Ganqika. They have completed the entire project by the end of the year by installing another 90 wind turbines with tower heights of more than 70 meters and turbine sections up to 75 tonnes in desert condition.
Currently, the Chinese energy specialist owns a total fleet of six GTK1100s, four being GTK1100 and two being GTK1100-1. The difference between the two models is that the GTK1100-1 has a stronger carrier and tower for higher lifting capacities. They are also the first company in the world to buy a GMK7450 as well.
