Product Description

Elevator Links are designed to hang elevators from Top Drive System or Hooks. Each elevator link of one pair is forged from one single billet of high strength alloy steel, heat treated and MPI tested. Additional material is added in critical wear areas for extended life.  The design safety factor and design verification of the elevator links conform to requirements of API Spec 8A or API Spec 8C, any elevator links are proof load tested to 1.5 times the working load.
Each elevator link of one pair is marked with Serial Number for traceability.
Elevator links are available in 150t,200t, 250t, 350t and 500t rating loads 
According to the structures, Elevator Links have two forms: Type DH & Type SH.
