Lumber Conveyor Chains 81X 81XH 81XHH 81XHS 81XRT 3939
Lumber conveyor chains are durable, high-strength chains used in the timber industry for efficient material handling. They are made of steel, come in various sizes, and can be customized to fit specific conveyor systems. With proper maintenance, they provide reliable operation and are a valuable investment for sawmills and lumber yards. Most commonly, this 81X chain series is found in the lumber and forestry industry and is available with upgrades such as “chrome pins” or heavier-duty side-bars. Our high-strength lumber conveyor 81X series chain is manufactured to ANSI specifications and dimensionally interchanges with other brands, meaning sprocket replacement is not necessary.

Application of Lumber Conveyor Chains
Lumber conveyor chains are specifically designed to handle the unique requirements of the lumber industry. These chains offer durability, strength, and precision, making them ideal for various applications within the lumber and wood processing sector. Here are some common applications of lumber conveyor chains:
1. Sawmills: Lumber conveyor chains are extensively used in sawmills for the transportation of logs, boards, and other wood materials. They are employed in log handling systems, log sorting lines, and log decks, facilitating the smooth and efficient movement of timber throughout the sawmill operations. These chains are designed to withstand heavy loads and harsh environments commonly encountered in sawmill settings.
2. Sorting and Stacking Lines: Lumber conveyor chains of engineering chains are commonly used in sorting and stacking lines within the lumber industry. These chains facilitate the separation, sorting, and stacking of boards based on their size, grade, and other specifications. They ensure the proper alignment and positioning of the lumber, enabling efficient downstream processes such as packaging, bundling, and storage.
3. Drying Kilns: Lumber conveyor chains are employed in drying kilns to transport lumber through the drying process. These chains are designed to withstand high temperatures and harsh conditions, ensuring reliable operation within the kiln environment. They provide precise control over the movement and exposure of lumber to heat and airflow, optimizing the drying process and minimizing quality issues.

4. Pallet Manufacturing: Lumber conveyor chains find applications in pallet manufacturing operations. They are used to transport lumber components through cutting, nailing, and assembly processes, facilitating the creation of pallets of various sizes and configurations. These chains provide stability and accuracy, ensuring the proper alignment and positioning of pallet components during production.
5. Timber Treatment Facilities: Lumber conveyor chains are utilized in timber treatment facilities where wood materials are processed for preservation and protection against decay and pests. These chains transport the timber through various treatment stages, including pressure treatment, vacuum treatment, and chemical application processes. They are designed to withstand the chemicals and harsh environments associated with timber treatment.
In summary, lumber conveyor chains find applications in sawmills, planing and milling machines, board, and panel handling systems, sorting and stacking lines, drying kilns, pallet manufacturing, timber treatment facilities, wood recycling and chipping operations, specialized woodworking machinery, and green chain conveyors. These chains offer durability, strength, and precision, ensuring the smooth and efficient movement of lumber throughout various wood processing applications.
