How to Select 81X Series Log Puller Conveyor Chain
When choosing log puller conveyor chains, start with working load and operating conditions. The standard 81X series is the preferred option for wood processing lines.
For light to medium duty and general log conveying, pick 81X. Choose 81XH for moderate heavy loads and frequent operation. 81XHH is designed for extra heavy-duty, high-load and harsh working scenarios. If you need deeper link plates for improved load capacity and impact resistance, 81XHD is the ideal choice.
All models feature uniform pitch and reliable structure. Prioritize chain strength, wear resistance and anti-shock performance to match your equipment load, running speed and material type, ensuring stable operation and long service life.
