FAQ

Q1: What API standards do your traveling block/hook comply with?

A: All our traveling block/hook assemblies are strictly manufactured in accordance with API Spec 8C PSL1 standard, and we hold the official API monogram license. The products meet the international oilfield hoisting equipment quality requirements.

Q2: Are your traveling block/hook parts interchangeable with mainstream OEM products?

A: Yes. Our key components (sheaves, bearings, safety locks, etc.) are designed to match OEM specifications and quality levels, allowing direct replacement for most global mainstream brands’ traveling block/hook parts.

Q3: What is the service life of your traveling block/hook under normal working conditions?

A: With proper maintenance and routine inspection, the service life of our traveling block/hook can reach over 10 years. Sheaves and bearings, as wearing parts, can last 3–5 years under standard operating conditions.

Q4: Can you provide custom solutions for special drilling or workover rigs?

A: Yes. We offer custom services including load capacity adjustment, sheave configuration modification, and special material selection to meet the requirements of different rig models and operating environments.

Q5: What kind of heat treatment do your key components use?

A: Key components such as hook rods and critical driving parts adopt carburizing heat treatment. Sheave grooves are processed by intermediate frequency quenching to improve surface hardness and wear resistance.

Q6: What safety features are included in your traveling block/hook?

A: Our products are equipped with safety positioning devices, locking mechanisms, anti-jump sheave guards, and optional mechanical/hydraulic bumpers to ensure safe and reliable operation.

Q7: Do you provide on-site installation guidance and after-sales service?

A: Yes. We provide detailed operation manuals, remote technical support, and can arrange on-site service engineers to assist with installation, commissioning, and troubleshooting for key projects.
