<p>A pole platform (10), to support a load or person above ground on a pole (P), has a planar deck (20) of insulated material, mounted on a main frame (11) which incorporates convergent side rails (12, 13). A flexible 5 restraint, such as a metal chain (30), passes around the pole (P) and is releasably connectable to the main frame (11). The ends of the side rails (12, 13) which engage the pole (P) have pairs of upper and lower abutment blocks or pads (40, 50) located below the chain (30), where the abutment blocks or pads (40, 50) have abutment faces (41, 42, 51, 52) inclined to the 10 longitudinal axes of the side rails (12, 13); and the lower abutment blocks or pads (50) have a Shore (Durometer) A hardness measurement at least 5 higher than the measurement for the upper abutment blocks or pads (40).
