The Stierli rotator was developed to turn heavy and large loads like beams and welded structures quickly and safely without a crane. This allows you to save a lot of working time and increase productivity. This welding positioner or welding manipulator functions as a lifting and rotating device with reliable chains. The turning device is not only used for beam welding, but other sections can also be turned with it, e.g. the use as pipe turning device. Loading is impressively simple with the overhead crane or by pushing the rotator to the sides. The rotator is also available with rollers. However, the smaller models can be positioned very easily with the hand pallet truck, whereby the distance between the stands of this welding device is freely selectable.
