Stanje: novo, Leto izdelave: 2025, nosilnost: 2.000 kg, 3-axis rotary and tilting positioner, 2000 kg load capacity, clamping plate diameter 0.8 meters These units have proven their effectiveness in the fields of construction and agricultural machinery, commercial vehicles, industrial trucks, as well as in the aerospace and energy technology sectors. They are ideally suited for welding, assembly, machining, and related applications. Their sturdy and robust design, coupled with flexible three-axis positioning capability—including overhead positioning—and ease of operation, make them ideal for welding, assembling, and handling large workpieces. • Accelerates production and increases productivity • Optimal workpiece positioning improves welding quality and allows for higher deposition rates • Enhanced safety—dangerous crane operations are largely eliminated • Simultaneous positioning on up to three axes without the need for time-consuming clamping changes • Simple operation and ergonomic processing reduce operator fatigue and provide effective protection • Flexible, modular adaptation and custom special designs available Principle of operation: By arranging the load arm rotation axis above the clamping plate, the arm acts as a counterweight to the workpiece. As a result, these machines offer significantly greater performance than conventional rotary-tilt tables or rotary-tilt positioners. This design allows handling of the specified loads in any position. Thanks to the infinite rotation capability of both rotary axes and the additional elevation adjustment, all workpiece positions—even overhead—are possible. • Steplessly adjustable turntable speed: 0.05 – 0.6 rpm • 2000 kg load capacity Njdpfx Adsxbhp Hsyswb • Radio remote control included • Rotation: 360° continuous • Tilting: 360° continuous • Lift: 1000 – 1500 mm • Arm outreach radius: 1.2 meters

Stanje: skoraj kot novo (rabljeno), Leto izdelave: 2022, Stierli- ROTATOR 600 / 6 t 360° rotating device for fast and safe turning and rotating of beams, profiles, and welded assemblies. Suitable for welding, fettling, rapid weld inspection, as an assembly turning device, etc. Nwsdpfx Aogqgb Uedyeb Capacity: 6 t Swivel circle diameter: 600 mm (e.g. HEB 600 beam) Part length: freely selectable (stands are freely positionable using a pallet truck) Working height adjustment: steplessly adjustable The Stierli Rotator was developed to enable fast and safe turning of heavy and large loads such as beams and welded constructions without the use of a crane. This saves you considerable working time and increases productivity. This welding positioner or welding manipulator acts as a lifting and turning device operated with reliable chains. The turning device is not only suitable for welding beams; other cross-sections—such as pipes—can also be rotated, functioning, for instance, as a pipe turning device. Loading is impressively easy using an overhead crane or by forklift. The rotator can be conveniently positioned with a pallet truck, while the distance between the supports of this welding fixture is freely adjustable.
