DF-20 Hydraulic Rotary Drilling Rig for Bridge Piling with 30m Max Depth and CE Certification

30 meters is the maximum you'll get out of this, and that's a hard limit, not a suggestion—if your bridge piling specs call for deeper, you're looking at a different class of machine entirely.

Most buyers we deal with are drilling to about 20 meters or so for typical bridge foundations, so the 30m ceiling covers the vast majority of jobs without pushing hydraulic system too hard, and the 24000N.m torque at 10-30 RPM handles both clay and rockier ground pretty well.

The mast tilts ±4° sidewards and 4° forwards, which basically lets you correct for uneven ground without repositioning the whole 16-ton crawler chassis, and the auxiliary winch pulls 10KN at 50m/min if you need to haul anything up or down the hole.

125KW Cummins engine with water cooling and a turbocharger means it runs all day without overheating, but what you really want to check is the gradeability—25° max slope is fine for most construction sites, though steep riverbanks can be a problem.

Drilling diameter runs form 500mm up to 1500mm depending on the Kelly bar setup and whether you're using a twist bit or a barrel drill, and we usually have both in stock but confirm lead time (typically 2-4 weeks) if you need a specific diameter.

CE and ISO 9001 are on the paperwork, RoHS too, and teh whole thing ships on a standdard flatbed at 9800×2400×2900mm, so you'll need a lowboy trailer unless you want to disassemble the mast.
