Casing Oscillator
Casing Oscillator
The Casing Oscillator is specialized equipment designed for full casing construction in unstable and complex ground conditions.
It drives the casing to perform clockwise and counterclockwise oscillating rotation through a powerful clamping mechanism, effectively reducing resistance during casing installation and extraction.
Hydraulic cylinders control the downward and upward movement of the casing, ensuring stable, safe, and efficient construction operations.

Product Description
Product Features
The casing oscillator is a specialized machine designed for full casing drilling systems.
The equipment drives the casing to perform clockwise and counterclockwise oscillating rotation through a clamping mechanism, effectively reducing resistance during casing installation and extraction.
Hydraulic cylinders are used to control the lowering and lifting of the casing, ensuring stable and safe operation.
Applications
The casing oscillator is primarily used in unstable soil conditions, such as soft soil, gravel layers, and gravelly soils. The equipment is capable of clamping large-diameter casings up to 3300 mm, allowing the casing to rotate in both directions or move vertically along the borehole axis.
When used in combination with grabs or auger drilling tools, it enables reliable casing-follow drilling operations.
Typical applications include:
- Urban metro foundation construction
- Deep foundation pit support and secant pile construction
- Urban renewal and reconstruction projects
- Pile extraction and obstruction removal
- Railway, port, road, and bridge engineering
- Bored pile construction for high-rise buildings and hydraulic engineering projects
Applicable Ground Conditions
Suitable for cobble layers, silt, quicksand, fine sand, fractured rock, karst formations, backfilled soil, marshland, as well as river and lake environments where conventional slurry wall support methods are ineffective.
