Q
What rig horsepower range are your sheaves compatible with?
Our sheaves are available in a range of outer diameters from 600 mm to 1800 mm and groove diameters from 26 mm to 46 mm, allowing compatibility with rig models ranging from 1000 HP to 3000 HP.
Q
Which OEM drilling equipment brands are your sheaves compatible with?
Our sheaves are fully compatible with major OEM brands including BOMCO, LS NOV, Honghua, RG, Rongsheng, EMSCO, and other well-known international drilling equipment manufacturers. High interchangeability is guaranteed.
Q
What quality inspections are performed on each sheave before shipment?
Every sheave undergoes ultrasonic testing (UT) and magnetic particle inspection (MPI) before shipment to ensure structural integrity. Full production traceability from raw material to final inspection is maintained and documentation is available.
Q
What is the expected service life of your heavy duty 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. The induction-hardened rope grooves significantly extend both sheave and wire rope service life.
Q
Can sheaves be customized to meet specific project requirements?
Yes. We offer customizable options including different sheave outer diameters, groove sizes, rope capacities, and bore configurations. As a professional source factory with over a decade of experience, we can accommodate both standard and project-specific designs. Please contact our sales team with your technical requirements.
