Base, column, boom and gear head are made of premium high-quality cast.
Major design features include a large column and a highly torsion-resistant boom.
Boom height adjustment via a powerful motorized drive and vertical spindle.
The boom lifting gears run in an oil-bath for maximum reliability and minimum wear.
Advanced column swivel design with optimized clamping features maximum rigidity and minimum clamping offset.
Swivel axis and travel axis features extremely smooth operation to make the operator's everyday production work easier.
The gears feature hardened and precision-ground chromenickel steel gears for smooth and low-noise operation.
All gear parts are lubricated reliably via oil pump.
The main spindle runs on precision bearings and features an automatic spindle brake.
