Demolition and sorting grabs are universal tools for demolition, sorting, and loading all kinds of materials. The name Multi Grapple is quite a good description for them. The basic structure is quite simple and similar for all brands: a rigid main body with two moving jaws mounted on both ends of the frame. The jaws are powered by one or two hydraulic cylinders and they are connected together with a steel bar so that they move simultaneously. For heavy applications, these excavator grapples are always equipped with a powerful hydraulic rotator but for light loading and sorting jobs, a tilt rotator can replace it. A tiltrotator (known under a number of trade names) is a hydraulic attachment/tool used on most excavators, and backhoes between 1,5–40 tons in the Nordic countries (Sweden, Finland, and Norway)
