They are suitable for welding, assembly, machining, and more. With their stable and robust construction, flexible three-axis positioning (including overhead), and easy operation, they facilitate welding, assembly, and handling of large workpieces. - Faster production and increased productivity - Optimal positioning of the workpiece improves welding quality and enables higher deposition rates - Enhanced safety by significantly reducing dangerous crane handling - Simultaneous positioning along up to three axes without cumbersome re-clamping - Easy and ergonomic operation protects and relieves the operator - Flexibility thanks to modular adaptability and custom configurations Basic Principle: Due to the arrangement of the swivel arm rotation axis above the clamping plate, the arm acts as a counterweight to the workpiece. As a result, these machines are significantly more powerful than tilt rotary tables or tilt-rotational positioners. This principle allows handling of the specified loads in any position. Thanks to the endless rotation of two axes and additional height adjustment, all workpiece positions (including overhead) are possible.
