COMPACT ROTARY HEAD CDE20
Without a doubt the CDE20 is the strongest compact rotary head with a large open center on the market and perfect to install cast in situ full displacement piles. Together with a CCS clamping system and a 44 ton total extraction force the casing can be extracted after concreting.
A rack and pinion system creates 14 ton pull down force in combination with a FUNDEX CD20D rig.
