Product Introduction:
Crawler crane and truck crane hinge pins are vital connecting components for lifting equipment. Acting as the structural joints between the crane boom and main body, they undertake critical load transmission while enabling flexible boom rotation and stable overall operation. Whether for heavy-duty hoisting of crawler cranes or flexible rapid operation of truck cranes, the quality and performance of these hinge parts directly determine the crane’s operational safety, structural reliability and working efficiency.
Product Advantages:
We implement full-process inspection covering incoming raw materials, semi-finished products, production processes and finished goods. Every link undergoes strict testing and quality checks, achieving comprehensive quality control throughout the whole workflow to ensure every product meets high-standard specifications and stable reliability. We own complete full-process processing capability, integrating forging, heat treatment, precision machining, surface treatment and finished product inspection in one-stop production. It enables independent manufacturing from raw material to final product, shortens production cycles, controls delivery quality, and supports both standard and customized orders efficiently. We provide full-range product portfolio with complete specifications, diverse models and customizable sizes. Our full-range product lineup can fully match different working conditions, industry demands and customer drawing requirements, offering one-stop procurement solutions and strong market competitiveness.
Production Process:
Raw material inspection → Cutting → Forging → Normalizing → Rough turning → Rough milling → UT → Quenched and tempered → Shot peening → MT → Finished turning → Finish milling → MT → CMM/GMM → Cleaning packaging
Packaging And Shipping:
Our professional quality control team adheres to rigorous standardized procedures for every customer order. Prior to shipment, all finished products undergo meticulous deep cleaning to remove machining residues, oil stains and impurities. Each piece is marked with clear, unified labels for complete batch traceability and easy identification, while professional industrial-grade anti-rust treatment is applied to provide reliable protection against moisture, oxidation and corrosion during long-distance transportation and storage. Every product is then subjected to strict comprehensive visual and appearance inspection, with every detail carefully checked to ensure flawless surface condition and qualified quality. Only fully verified products are allowed to proceed to packaging. We adopt customized shockproof, moisture-proof and wear-resistant packaging materials for safe packing. All packaged goods are systematically classified and stored in our well-managed, tidy warehouse under proper environmental control, keeping products in perfect condition and ready for timely arrangement and immediate delivery at any time.
