DQ70 Top Drive 450Ton Rated Load Top‑Drive for Deep Well Drilling & Workover Operations
Description:
DQ70 Top Drive is a heavy‑duty AC VFD top‑drive system with 450Ton rated load, specially engineered for deep‑well drilling and workover operations on land rigs. Manufactured complying with relevant API standards, it delivers powerful torque output, wide speed adjustment range and stable performance for 7000‑meter‑class well operations.
Powered by dual main motors, this top‑drive supports continuous 360° rotation while circulating drilling mud downhole. Equipped with reliable IBOP, robust back‑clamp assembly and heavy‑load bearing groups, it ensures well‑control safety and stable pipe handling under harsh field conditions. The integrated PLC control system provides functions of fault diagnosis, safety interlock and real‑time monitoring for convenient onsite
Designed for heavy‑load tripping, drilling, fishing and well servicing jobs, the DQ70 top drive improves operational efficiency and reduces accident risks. Compact modular structure simplifies maintenance and component replacement. Custom‑adaptation is available to match different land drilling & workover rigs, serving as core rotating power equipment for global oil‑gas deep‑well projects.
