250-Ton Rated Capacity for demanding drilling environments
✔ Standard 2-1/4" × 60" dimensions for seamless rig compatibility
✔ Forged high-strength alloy steel construction
✔ Heat-treated and NDT inspected for maximum reliability
✔ Manufactured in compliance with API 8C standards
Elevator Links are designed to suspend elevators from the Top Drive System or hooks. Each elevator link in a pair is forged from a single billet of high-strength alloy steel, then heat treated and subjected to MPI inspection. Additional material is incorporated in critical wear areas to extend service life. The design safety factor and verification of the elevator links comply with API Spec 8A or Spec 8C requirements. All elevator links are proof load tested to 1.5 times the rated working load. Each link in a pair is marked with a serial number for full traceability. Elevator links are available in rated capacities of 150t, 200t, 250t, 350t, and 500t.
