GTA has developed, built and put into operation a new generation of lifting workbenches for tunnel construction.
The new vehicles are characterized by their high performance as well as their high lifting capacity and range. In connection with the fulfillment of the latest European safety standards, GTA sets standards on the market.
The tripple boom equipped GTA®Lifter 1600T is designed for work in tunneling projects in which support arches have to be set and full flexibility should be be kept. The central support manipulator can be equipped with different profile brackets and thus is able to position different arch profiles with a weight up to 1200 kg in place.
The GTA®Lifter 750 provides a working platform carrying 750 kg and is mainly used for the installation of light steel grid arches and steel mash.
The GTA®Lifter 750D is equipped with two working baskets, each carrying 750 kg. The independent movements of the two booms and the extreme reach of 12 m height an 16 m width make this double boom GTA®Lifter 750D to an ideal device for large tunnel cross-sections.
The GTA®Lifter 1500E offers a work platform with a working area, which can be enlarged by hydraulically extendable elements to more than 10 m² and is able to carry loads of 1500 kg.
The single boom GTA®Lifter 2500A is especially designed for the setting of heavy support arches. Lifting loads of up to 2.500 kg at working heights up to 11,9 m are the outstanding features of this type of machine.
