CQC (Chongqing Chengqi Machinery Co., Ltd.) has established itself as a leading manufacturer of undercarriage components for medium and large tracked excavators, drills, bulldozers, and other heavy machinery. With a strong focus on both OEM (Original Equipment Manufacturer) and ODM (Original Design Manufacturer) services, CQC offers complete customization and reverse engineering solutions for track sprocket wheels, chain links, track rollers, idlers, and track shoe assemblies. Our production lines are fully integrated, enabling us to meet rigorous original equipment specifications while also supporting aftermarket upgrades and performance modifications. Whether customers require standard replacement parts or tailor-made designs for specific terrain and working conditions, CQC delivers precision, consistency, and scalability.

2. Proven Reliability in Harsh Conditions – Performance Backed by Years of Mining & Engineering Practice

The Komatsu PC400-6 track sprocket wheel assembly (Part Nos. 2082731221 and 2082761210) exemplifies CQC’s commitment to durability and operational safety. Manufactured from high-strength alloy steel with advanced heat treatment processes, these sprocket wheels offer exceptional wear resistance, optimal tooth engagement with track bushings, and extended service life. Over the past decade, CQC undercarriage components have been extensively deployed in mine sites, large-scale earthmoving projects, quarry operations, and infrastructure construction across five continents. Field data from end users consistently demonstrate that CQC sprockets maintain structural integrity under high-impact loads, abrasive conditions, and extreme temperatures – reducing downtime and lowering total cost of ownership for fleet operators.

3. Vertically Integrated Production & Professional Technical Team

CQC’s strength lies in its fully self-owned industrial ecosystem, which eliminates quality variability commonly associated with outsourced manufacturing. Our facilities include:

• Casting foundry – Producing rough blanks for sprockets, idlers, and support rollers.
• Forging plant – Forging high-tensile track links and other critical load-bearing components.
• Forged bucket tooth factory – Specializing in wear parts for excavator buckets and rippers.
• Final assembly plant – Dedicated to track sprocket wheel assemblies, track chain groups, and complete undercarriage kits.
• CNC machining workshop – Equipped with advanced vertical lathes, gear hobbing machines, and precision boring mills for spline and bolt hole finishing.

Our in-house R&D and quality assurance team comprises over 50 metallurgical engineers, mechanical designers, and process technicians. They continuously improve tooth profile geometry, casting/fixture integrity, and heat treatment cycles to match or exceed Komatsu’s original design standards. Every batch of sprocket wheel assemblies undergoes ultrasonic flaw detection, hardness testing, and dimensional laser scanning before release.
