CENTER LATCH ELEVATOR

TECHNICAL SUMMARY

API 8C Center Latch Elevators include TA/DD/DDZ series, they are Ideal for onshore, offshore, directional and ultra-deep well operations, their platform-step and tapered-step options meet diverse drilling needs. They deliver reliable performance across conventional and specialized drilling projects, trusted by global drilling contractors for tubular running, lifting and suspension.

 

 

1. The TA Series excels in platform-step versatility, compatible with NU/EU joint drill pipes, tubings and small-to-medium casings, serving as a cost-effective choice for standard onshore rigs.

2. The DD Series is engineered for heavy-duty applications, with heavy-wall forged structure and reinforced load-bearing capacity to handle drill collars and heavy-wall tubings in harsh deep well conditions.

3. The DDZ Series adopts an 18° tapered-step design with replaceable liners, precision-matched to tapered-joint drill pipes, offering enhanced vibration-dampening performance for complex operations like horizontal wells.
