Construction 180 Rotary Drilling Rigs

What 180 Rotary Drilling Rigs are used for

Piles carry a structure's load down past weak topsoil to firm ground or rock. A rotary rig drills these piles quickly and with little noise or shaking compared with driven piles, which matters on busy city sites and next to existing buildings.

Typical projects include:

• Bridge and flyover piers
• Foundations for towers, silos and tanks
• Retaining walls built from secant or contiguous piles
• Power line and wind tower bases

Tools for different ground

The drilling tool is swapped to match the soil. A drilling bucket suits clay, sand and loose gravel, while an auger clears firm, dry soil fast. For hard rock layers, a core barrel with carbide or roller bits cuts through where a bucket would stall.

Buyers usually ask us for a tool set that matches the soil report from their site, so we suggest sending the borehole log with your enquiry.

Typical build of this class

The specification table below gives the details for this model. Values marked as typical describe rigs of this type and are confirmed in writing for your order:

• Controls: hydraulic rotary table, operator cab controlled
• Drive: diesel engine, kelly bar rotary drive, hydraulic winch
• Build: steel mast, kelly bar, drilling bucket/auger
• Range: 1.5-3.5 m drilling diameter, up to 100 m depth across the class

The real depth and diameter for a given rig depend on the kelly bar length and the torque, so we confirm both before we quote. To compare a larger machine, see the 220 rotary drilling machine or the 280 rotary drilling machine.

Export and delivery

A rig of this size is shipped with the mast and kelly bar taken down, and the parts are packed for sea transport. We ship to Nigeria, Kenya, Ghana and other markets and agree the spec, Incoterm and delivery date before production begins. Our shipping and export documents page explains the trade terms we quote.
