A used CFA (continuous flight auger) piling rig is the right pick for noise-sensitive urban foundations where casings are impractical, delivering 600–1,200 mm piles in soft ground. Expect an indicative USD 120,000–220,000 FOB Shanghai; auger condition and concrete-line integrity drive the real price.

What Are the Core Specs and Where Does CFA Fit?

Field	Typical value on a CFA rig
Max pile diameter	1.2 m
Max pile depth	27 m
Auger torque	120–180 kN·m
Concrete pump output	60–90 m³/h
Mast / leader height	22–28 m
Pull-down / crowd force	240 kN
Engine power	194–261 kW
Tooling included	Auger + tremie pipe

CFA suits dense city sites — metro stations, malls, hospitals — where vibration and spoil are restricted. For hard rock or >1.5 m diameter, switch to rotary bored or diaphragm wall methods.

How to Inspect a Used CFA Rig's Condition?

●Auger: check flight wear, straightness, and hardfacing loss at the cutting edge.

●Drive head / gearbox: confirm torque under load; listen for whine or backlash.

●Concrete line: inspect the full tremie path for worn sections and seal failure.

●Hydraulics: test crowd and rotary at pressure; look for cylinder drift.

●Leader / mast: verify guide rail wear and any weld repairs.

●Electronics: pull fault logs; a silent panel after a hard job is a red flag.

What Does a Used CFA Rig Cost, and What's the Export Process?

Indicative ranges by condition:

●Reconditioned: USD 190,000–220,000

●Working, average wear: USD 150,000–185,000

●Project-retired: USD 120,000–145,000

Export steps: inspection video → proforma invoice → fold leader and secure auger for 40HQ → lashing and booking → Shanghai export declaration → Bill of Lading. We provide export documents; destination clearance is the buyer's responsibility.

What Are the Common Pitfalls and Who Handles Customs?

●Pitfall 1: Auger depth claimed but only short flights present — measure the leader.

●Pitfall 2: Concrete pump seized from idle; demand a live pump test.

●Pitfall 3: Undeclared leader weld that fails on first crowd load.

●Responsibility: seller supplies export paperwork and honest reports; import duty, VAT and clearance are the buyer's scope. We do not promise "包清关 / 包税".

How We Evaluated These Rigs

We ranked CFA rigs by logged pile metres, third-party auger inspection, and a live concrete-pump test. Each unit passed a crowd-and-rotary load test before listing. Figures above are indicative and tied to the unit's inspection file.

FAQ

Can CFA work in sandy or water-bearing soil?

Yes, with proper tremie sequencing; it is weaker in cobbles and hard rock.

Is the concrete pump included?

A standard pump is included unless stated; verify output rating.

How long to ship to Southeast Asia?

About 10–15 days from Shanghai plus clearance.

Do you test the auger under load?

Yes, every listed rig includes an auger and pump test video.

Does it fit a 40HQ?

The leader folds and the auger secures inside; we send the lashing plan.
