Extracting 1500mm double wall casing with 1500mm hydraulic casing extractor
A 1500mm hydraulic casing extractor (casing puller) is heavy geotechnical foundation equipment designed to clamp onto and extract temporary steel casings up to 1500 mm in diameter from bored piles, secant pile walls, and deep foundations.
It allows service contractors to free up rotary drilling rigs or crawler cranes from performing high-load extraction operations, preventing mast damage and reducing fuel/machine wear during concreting.

Key Operational Features
Multi-Cylinder Jacking System: Uses 2 to 4 heavy-duty vertical hydraulic cylinders pushing against ground bearing plates to break casing-skin friction.
Radial Clamping Mechanism: Powered wedge or segmented jaw system to grip smooth or jointed double-wall casings without crushing the casing profile.
Power Source Compatibility: Driven via a dedicated standalone diesel/electric hydraulic power pack or directly tied into the auxiliary hydraulic lines of a base rig/crane.
Reduction Inserts (Adapter Collars): Interchangeable clamping jaw inserts allowing the same 1500mm frame to handle smaller standard sizes
Common Applications
1.
Concreting Phase in Bored Piling: Extracting temporary casing sections step-by-step as concrete is placed via tremie pipe.
2.
Secant Pile Walls: Pulling temporary casings in stiff clay, boulder beds, or high-friction strata where base rig winches lack pulling capacity.
3.
Obstruction Removal & Pipe Recovery: Recovering bound or jammed steel pipes in deep foundation applications.
