The Fly drill method is a relatively new concept for bored piling. The drilling unit with rotary head, kelly bar and drilling tool is suspended by the hoist rope of the base carrier crane. The suspended drill, free from base machine, has high versatility when working in different ground levels and with varying working radius (e.g. piles in slopes). The Fly drill system is ideally suitable for marine offshore piling from a floating barge. Suitable for drilling bored piles from up to 1800mm diameter up to 42m deep.
