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 standards does the MT-YC traveling block comply with?
The MT-YC traveling block is manufactured in accordance with API Spec 8C (Drilling and Production Hoisting Equipment) and the Chinese industry standard SY/T 5527, ensuring it meets both international and domestic compliance requirements.
❓ What is the maximum hook load capacity available in this series?
The series ranges from 900 kN (MTYG90) up to 4,500 kN (MTYC450), covering a wide range of drilling rig requirements from light to ultra-heavy-duty applications.
❓ Are third-party inspection reports 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 assurance of quality and compliance.
❓ Are the sheaves and bearings interchangeable with crown blocks?
Yes. When designed for the same hook load rating, the sheaves and bearings of the MT-YC traveling block are interchangeable with those of the crown block. This significantly simplifies spare parts inventory management and reduces maintenance costs.
❓ How are the sheave grooves treated to improve wear resistance?
The sheave grooves undergo quenching and surface hardening treatment, which greatly increases resistance to wear caused by prolonged contact with heavy drilling lines, extending the service life of the unit.
❓ What wire rope diameters are compatible with this traveling block series?
Depending on the model, compatible wire rope (drilling line) diameters range from 26 mm (MTYG90) to 38 mm (MTYC450). Each model is matched to the appropriate wire line diameter to ensure safe and efficient load handling.
