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
Q
What 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. It also conforms to the Chinese industry standard SY/T 5527, ensuring compliance with both international and domestic requirements.
Q
What is the maximum hook load capacity available in this series?
The series covers a wide range of hook load capacities. The largest model, MTYC450, offers a maximum hook load of 4,500 kN, while the smallest model, MTYG90, provides a maximum hook load of 900 kN, making the series suitable for various drilling rig configurations.
Q
Are the sheaves and bearings interchangeable with the crown block?
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 design feature simplifies spare parts management and reduces maintenance downtime significantly.
Q
What surface treatment is applied to the sheave grooves?
The sheave grooves undergo quenching and surface hardening treatment. This process significantly increases wear resistance, allowing the grooves to endure prolonged and heavy contact with the drilling wire line without premature damage or degradation.
Q
Is third-party inspection and certification available for these traveling blocks?
Yes. Third-party witness inspection and certification reports are available from recognized international bodies including Bureau Veritas (BV), CCS, ABS, SJS, and others. This ensures full traceability and quality assurance for project and procurement requirements.
Q
What wire rope diameters are compatible with this traveling block series?
The series accommodates wire rope diameters ranging from 26 mm to 38 mm depending on the model. Smaller models such as MTYG90 use a 26 mm wire line, while larger models such as MTYC450 are designed for a 38 mm wire line, ensuring optimal load distribution and operational safety.
