Q What rig models are these sheaves compatible with?
Our sheaves are designed to be compatible with a wide range of rig models from 1000 HP to 3000 HP, and are fully interchangeable with equipment from BOMCO, LS NOV, Honghua, RG, RONGSHENG, EMSCO, and other major drilling equipment brands.
Q What material is used in manufacturing the sheaves?
The sheaves are manufactured from 45# Alloy Steel (equivalent to AISI 1045 / JIS S45C). The bodies are forged and welded, with rope grooves that are heat-treated and induction hardened to ensure high durability and fatigue resistance.
Q What is the expected service life of your sheaves?
Under normal drilling conditions, our sheaves are designed for a service life of 8 to 10 years, provided that periodic bearing and groove maintenance is carried out as required.
Q Can the sheaves be customized to specific dimensions or groove sizes?
Yes. We offer customizable options covering sheave outer diameters from 600 mm to 1800 mm and groove diameters from 26 mm to 46 mm. Custom designs for different rope capacities and rig configurations are available — please contact our sales team with your technical requirements.
Q What quality inspections are performed before shipment?
Every sheave undergoes rigorous pre-shipment inspection including ultrasonic testing and magnetic particle testing to verify structural integrity. Full production traceability from raw material sourcing to final inspection is maintained, and third-party witness inspection can be arranged upon request.
