All MT-TC crown blocks are manufactured in full accordance with API Spec 4F (for drilling structures) and API Spec 8C (for drilling and production hoisting equipment). They also comply with the requirements of the industry standard SY/T 5527, ensuring safety and consistency with international regulations.
Each sheave in the crown block is individually certified to API Spec 8C(8C-0349), ensuring verified quality and performance under rated loads. To guarantee long service life, the sheave grooves are subjected to quenching and surface hardening treatments, which greatly improve wear resistance and minimize deformation under heavy loads.
Each unit is inspected and tested to meet international safety requirements, offering drilling contractors a product that is both trustworthy and cost-efficient in long-term operation.
