Hire Grove GTK1100 Fixed Crane

The owner of the first GTK1100 (Germany's Wiesbauer), actually contributed to the design of the crane, specifically for use in its windmill building projects. The crane made its debut on a 2007 project in Bade, Germany and has not looked back since.

The key features of the GTK1100 are its previously mentioned small footprint, its flexibility and mobility, and its remote operation. All three of these characteristics work so well for building windmills that the crane has been put to use in other applications with similar needs. Over the last five years the GTK1100 has been used at power plants, stadiums, docks, etc.

Key Design Element

The key design element which makes the crane so useful is its six-section telescoping tower. The tower is raised by a single stage telescopic cylinder to a maximum height of 76.5m. Better yet, the entire tower can go up in just about an hour.

Furthermore, because the tower is so compact and has no need of an operator's cab, the entire package can be transported on four or five standard sized trailers. By contrast, other similar cranes with equivalent lifting capacity need 15 or more trailers and days to set up and prepare. The GTK1100 can be disassembled, moved, and sent back up in one day's work.

It's easy to see with this description why the crane is so valuable to windmill construction. But not only is the crane mobile, it also doesn't require much space. Four single stage beams, at 12.7m each, make up the outrigger system. Additional stability is provided by tubular lattice bracing with a tension that can withstand a force of 1000 kN. even in work areas that are tight on space the GTK1100 doesn't have a problem.

In addition, the small footprint means two other very important things on remote sites: less ground preparation and less of a need for completely level surfaces. In terms of the former, the GTK1100 simply doesn't require the large amount of space other cranes require so there's less to prepare. In terms of the latter, Grove's state-of-the-art outrigger system means you can get away with slightly uneven ground with no worries.

Crane Operation

The GTK1100 boasts three separate engines: one as the power pack to raise and lower the tower, one to operate the superstructure, and the secondary auxiliary engine for the superstructure as well.

The superstructure engine is the main engine, and it's a turbocharged, six-cylinder Mercedes-Benz OM906LA diesel. It delivers 190 kW of power and maximum torque of 100 Nm, and has a fuel capacity of 850 litres. The auxiliary engine is a four cylinder Lombardini LDW1404. It produces 22.5 kW and 84 Nm. Both engines are water cooled.

Everything on the crane is controlled from the ground so there's no need for an operators cab. The ECOS electronic control system can be operated using either a cable connected consul, or on optional remote control unit.

The Superstructure

The GTK1100 offers a five-section TWIN-LOCKTM boom that can extend from 16 m to 60 m. The maximum tip height with the tower fully extended is 140 m. Sloughing is handled by three gears with independent piston motors, planetary gear, and auto braking system.

The total load capacity of the crane is 70 tons. While you won't be using it for really large-scale building projects, it is more than adequate for windmill building and other similar applications. It is a very cost-effective alternative to larger cranes that are harder to transport, harder to set up, and harder to start making money on.
