Compliance and Reliability
This series travelling block is manufactured in accordance with API Spec 8C, Drilling and Production Hoisting Equipment, the internationally recognized benchmark for traveling blocks, hooks, and related devices. It also conforms to the Chinese industry standard SY/T 5527, ensuring compliance with domestic requirements. To increase resistance to wear, the sheave grooves undergo quenching and surface hardening, enabling them to endure prolonged exposure to heavy drilling line contact without premature damage. Every unit is subject to rigorous inspection and load testing, so contractors can rely on consistent performance and reduced risk of downtime in demanding drilling environments.
Product Features
- The MT-YC traveling block is built with high strength sheaves and heavy duty bearings, providing smooth operation of the wire rope under dynamic loads.
- A practical advantage is the interchangeability of its sheaves and bearings with those of the crown block when designed for the same hook load, which streamlines spare part management and simplifies maintenance logistics.
- This compatibility, combined with durable structural design, lowers operating costs while improving fleet-wide efficiency for drilling contractors.
- Additional engineering attention has been given to alignment and load distribution, ensuring stable operation throughout extended drilling campaigns.
- With its durable construction and compliance with global standards, the MT-YC traveling block represents a reliable, field-proven choice for modern drilling applications.

Frequently Asked Questions
-
What international standards does the MT-YC traveling block comply with?The MT-YC traveling block is manufactured in accordance with API Spec 8C, the internationally recognized standard for drilling and production hoisting equipment, as well as the Chinese industry standard SY/T 5527, ensuring compliance with both global and domestic requirements.
-
What is the maximum hook load capacity available in this series?The series ranges from 900 kN (MTYG90) up to 4500 kN (MTYC450), covering a wide range of drilling rig requirements from light to heavy-duty applications.
-
Are the sheaves and bearings interchangeable with the crown block?Yes. When designed for the same hook load, the sheaves and bearings of the MT-YC traveling block are interchangeable with those of the crown block. This significantly simplifies spare part management and reduces maintenance complexity on the rig.
-
What treatment is applied to the sheave grooves to extend service life?The sheave grooves undergo quenching and surface hardening treatment, which significantly increases wear resistance and allows them to withstand prolonged contact with heavy drilling lines without premature damage or deformation.
-
Is third-party inspection and certification available for these traveling blocks?Yes. Third-party witness and inspection reports are available from recognized certification bodies including Bureau Veritas (BV), CCS, ABS, and SJS, providing customers with independent verification of product quality and compliance.
-
How many sheaves are available across different models in this series?The number of sheaves varies by model: the MTYG90 features 3 sheaves, MTYG135 has 4, MTYG170 / MTYC170 / MTYC225 each have 5, and the larger MTYC315 and MTYC450 models are equipped with 6 sheaves to handle their higher load capacities.
