Casing Rotator
Casing Rotator
The BEIYI Full Casing Rotary Drilling Rig adopts advanced full casing construction technology to provide stable, precise, and environmentally friendly drilling performance — even in low-headroom or confined-space projects.
By rotating the casing 360°, the system effectively reduces penetration resistance, maintains vertical accuracy, and minimizes ground disturbance — without generating slurry pollution.
-
360° full casing rotation for smooth penetration and extraction
-
Suitable for low-headroom and confined-space operations
-
High vertical accuracy with hydraulic alignment control
-
No slurry discharge and minimal impact on surrounding structures
-
Stable and energy-efficient performance in complex geological conditions

Product Description
Core Equipment for Full Casing Construction Systems
Applications & Advantages
- Low headroom operation capability
Suitable for construction in limited height environments, commonly encountered in urban building and bridge projects. - Wide application fields
Widely used in bridge construction, building construction, and petrochemical infrastructure projects. - Excellent adaptability to complex ground conditions
Suitable for pile foundation construction in complex strata such as quicksand, karst formations, and ultra-high backfill. - Support for multiple construction methods
Applicable to secant pile construction, subway steel column installation, as well as pile extraction and obstacle removal operations. - Environmentally friendly construction method
By utilizing steel casing protection, the system enables high-quality pile foundation construction with no or minimal slurry pollution, making it especially suitable for urban areas with strict environmental requirements and complex geological conditions.
Construction Characteristics
- Restricted working space
Limited construction space makes equipment access and material handling challenging, placing higher demands on construction planning and equipment adaptability. - High safety requirements
Complex surrounding environments require precise control of underground pipelines and groundwater levels to ensure construction safety. - Specialized construction process
Segmented or alternate excavation methods are often required to maintain safety and construction progress.
