The engineering department has developed a drill rig fall arrest device which is fitted to the top of the mast and provides a safe means of access for staff climbing the rig.
An inertia reel block allows free movement up and down the mast, but locks immediately in the event of a slip, thereby preventing a fall. The locating device ensures that the support point is always immediately above the working position, which keeps the wire free from snagging on the mast. |
