Founded in 2009, Qingdao Caroler Industry and Trade Co., Ltd. has nearly 20 years of experience in producing and selling construction machinery parts, with strong customer service and problem-solving capabilities. We mainly supply link assemblies, carrier rollers, track rollers, sprocket, and other accessories for heavy-duty apron feeders of various pitches and working conditions. We also provide undercarriage parts for 0.8–350 ton excavators and 20–900 horsepower bulldozers.


We offer factory-direct one-stop supply. Backed by our strong R&D and technical team, we provide customers with necessary data, and support them in product selection, new product development, after-sales issue analysis, and maintenance. We focus on supplying products from brands like Shantui, Komatsu, and Caterpillar, and own our OEM factory, providing OEM parts to mainstream machinery manufacturers for a long time.
As long-term suppliers to key clients such as Sinoma and Hazemag, we export to overseas markets such as Europe, Southeast Asia, Central Asia, and Africa. Our product quality has consistently earned positive feedback and high praise from customers.

The advanced seal ring integrates cutting-edge technologies of high-strength steel and synthetic materials, ensuring maximum sealing service life.

Manufactured through advanced technical design and subjected to deep case hardening, the track link delivers maximum strength and wear resistance.
All pin bushings are cold extruded from raw materials to ensure uniform distribution of steel fibers, followed by carburizing to achieve optimal core hardness and superior surface wear resistance.
Each pin undergoes specialized heat treatment and deep hardening to ensure excellent wear resistance. It is impact-resistant, stress-resistant, and most importantly, retains consistent robust properties.
The simple design makes the main link easy to clean, assemble and disassemble, while ensuring reliability and durability.
Able to provide single-tooth and three-tooth track shoes and swamp boat-shaped track shoes that can withstand extreme conditions and various working environments
