Significantly increase your productivity – save more than 30-40% of your working time.
The Stierli rotator was developed to turn heavy and large loads such as beams and welded structures quickly and safely without a crane. This saves you a lot of working time and increases productivity. This welding positioner or welding manipulator functions as a lifting rotating device with reliable chains. The turning device is not only used for beam welding, but can also be used to turn other cross-sections, e.g. as a pipe turning device. Loading is impressively easy with an indoor crane or by pushing the rotator in from the side. The rotator is also available with rollers. However, the smaller models can be easily positioned with a hand pallet truck, whereby the distance between the stands of this welding device can be freely selected.
