Short Mast Versions
The Short mast version of our kelly bar cylinder crowd machines are ideal for drilling with an overhead restriction. Drilling under power lines, existing bridges on inside a building is possible due to the limited height of the mast. With a large inner passage in the rotary, CZM’s can have interlocking kelly bars with more elements, that allow you to drill deep even on low over headroom.
