POST DRIVER SAFETY SYSTEM
A post driver having a shielding structure able to be raised and lowered on guides of and/or relative to a mast structure which guides the monkey or hammer. The monkey and/or a member or members dependent from it (e.g. whether part of a post cap or not) is able to interact with the shielding structure in order to uplift it to allow access to the impact zone or to where at least the top region of a post to be driven is, or is to be, positioned. The shield structure extends below the impact zone, i.e. where the impact face of the monkey will engage a post or post cap to be driven. Repeated blows by the monkey can be made with the lowered safety shield not moving with the monkey.
