Grapples

The conventional way of driving a bucket or a grapple is by having one or two cylinders acting on a lever, transforming linear into turning motion on the axis. This is a robust – and over the years – well Proven method. You also have the possibility of using an HPXdrive. This drives the shells by means of a helix screw working two axles, on which the shells are mounted. The HPXdrive has many advantages. It is maintenance free, compact and robust, and gives you a constant closing force. It also Provides for the possibility of using different shells on the same drive – you can adapt from using a narrow bucket to a wide bucket, and on to a rock grab by simply loosening and tightening eight bolts. This is perfect when carrying out a wide range of different jobs during the same week. And of course, when your current shells finally wear out you need only order a new pair of shells – the HPXdrive will still keep going for a long time.
