Abstract

A downhole transport assembly (100, 101) having first and second members (10, 20) having a common longitudinal axis, at least one of the members (10, 20) being rotatable about the longitudinal axis and movable along the longitudinal axis relative to the other member, the rotatable member having at least one engaging member (60), the or each engaging member (60) being configured and/or disposed on the rotatable member so that rotation of the rotatable member about the longitudinal axis causes the first and second members (10, 20) to move with respect to each other in opposite directions along the longitudinal axis.
