HZR1200 rig is the biggest and strongest hammer drilling rig on the market. HZR1200 drills up to Ø1220 steel casings, which is the biggest hammer drilled casing diameter. Even though HZR1200 is very strong machine, it is still versatile and very mobile contracting unit, which covers most of the infrastructural steel cased and rock drilling needs. This combination has a wide drilling diameter range capability from Ø406 to Ø1220, but it is optimal from Ø711 to Ø1220.
