Import Draw Works — Buy in Bulk from Supplier in China

The Draw Works from Dongying Lake Petroleum Technology Co., Ltd is engineered for heavy-duty drilling operations, featuring a main brake system of either belt or disc type and an auxiliary eddy current or EATON brake for controlled load reduction. All shafts and sprocket wheels are forged from alloy steel, with chains lubricated via forced oil circulation. The roller assembly includes a wire rope slot and is fitted with pneumatic clutches at both ends for smooth engagement, while the brake disc is cooled by circulating water and treated with middle-frequency quenching to enhance wear resistance.

The sprocket teeth and clutch components undergo the same middle-frequency quenching process to ensure durability under high torque. Gear shifting is managed through involute spline clutches, which provide precise engagement and reduce mechanical backlash. This design conforms to API Spec 7K, allowing the unit to carry the official API label, confirming compliance with international drilling equipment standards. The unit is built for continuous operation in harsh environments, with no reliance on hydraulic systems for primary braking.

These draw works are typically purchased by offshore and onshore drilling contractors operating in regions with high well depths and demanding torque requirements. Buyers commonly specify the auxiliary brake type based on regional safety norms and rig compatibility. Packaging is standard for heavy machinery: unit disassembled into major subassemblies, wrapped in corrosion-inhibiting film, and secured in steel frames. Lead time and Incoterms are confirmed directly with the supplier, as they vary by order volume and destination port.

Dongying Lake Petroleum Technology Co., Ltd is a manufacturer based in Huanghe Road, Dongying, China, with a verified harbor trust tier and a focus on drilling equipment components. The company supplies draw works systems to regional drilling contractors and integrates API-compliant design practices into production. Its listing indicates no public financial data, employee count, or export history, and no third-party certifications are referenced.

The supplier's profile shows no response rate or average reply time, suggesting limited direct buyer engagement on the platform. However, the technical depth of the product description and adherence to API Spec 7K indicate operational competence in mechanical design. Buyers should request factory audit reports or test certificates directly, as none are listed. The company does not claim international distribution or after-sales service networks.
