ABSTRACT A fall arrest device for a pole climber which has a main yoke with a respective spring biased arm at each end for partly encompassing a pole. The resiliently biased arms are movable in the same plane as the main yoke and also urge secondary yokes into contact with the pole to accomodate a range of pole diameters. Handles are attached to each arm for gripping by the pole climber to move the arms so that the fall arrest device can be raised or lowered, and each arm also has eyelets for receiving safety straps attached to the pole climber. In a preferred embodiment the arms have sharp projections for biting into the pole. A pull on the strap, due to slippage of the pole climber, causes the arms to move towards each other and the sharp projections to bite tightly into the pole. Alternative embodiments are also described.
