Abstract

A taphole drill is provided with a mounting arrangement including a jib arm which may be slewed about a primary pivot. The jib arm is pivoted itself to provide a first and a second limb and a control arm is included which is attached to the second of the limbs and the primary pivot. The control arm sets the angle of the first and second limbs as the arrangement is slewed. A pivoting link is provided to link the control arm to the primary pivot. As rotation about the primary pivot occurs the link pivots to proved two pivoting positions for the control arm. This increases the angle between the first and second limbs and extends the arrangement until the drill is in a drilling position. Rotation in the opposite direction retracts the arm until the arrangement is in a parked position. This reduces the floor area taken up by the taphole drill.
