Abstract

An equipment support, such as an IV pole, comprises an upper portion, a lower portion having a lower end configured to engage a socket, and an actuator movable relative to the lower end. When the upper portion is gripped by a releasable gripper, the lower end can be disengaged from the socket by moving the actuator from a first position to a second position. The lower portion can be telescoped relative to the upper portion by moving the actuator from the second position to a third position.
