Abstract

A positioning device for causing movement relative to a guide (10), the positioning device comprising at least two motion members (20), each member being actuatable between a retracted state and an expanded state, wherein upon actuation between the retracted state and the expanded state a motion member is movable into or able to increase gripping engagement with the guide and simultaneously cause relative movement between the device and the guide.
