Pin and Bar Chain: An Overview

Pin and bar chains are a popular type of conveyor chain, commonly used in the lumber industry for moving logs and lumber. With a simple yet robust design, pin and bar chains are also used in other industries such as agriculture, mining, and construction.

History and Classification

The first recorded use of chains for mechanical purposes dates back to ancient times, with evidence of chains being used in Greek and Roman machines. However, the modern design of pin and bar chains was developed in the early 20th century in response to the need for a reliable and durable conveyor chain for the lumber industry.

Pin and bar chains are classified based on the pitch, which is the distance between the center of one pin to the center of the next pin. The most common pitch size is 2 inches, but they can range from 1 inch to 4 inches. The pitch determines the load capacity and strength of the chain.

Advantages and Materials

One of the main advantages of pin and bar chains is their simplicity and ease of maintenance. They can be easily repaired by replacing individual pins or bars that have worn out, making them a cost-effective choice. Pin and bar chains are also made of durable materials such as carbon steel and stainless steel, making them resistant to wear and corrosion.

Installation, Maintenance, and Repair

Proper installation of pin and bar chains is essential to ensure their longevity and optimal performance. It is important to follow manufacturer's instructions and guidelines for installation. Regular maintenance, such as lubrication and inspection, can help prevent wear and tear and prolong the life of the chain.

When it comes to repair, individual pins or bars can be easily replaced without having to replace the entire chain. It is important to regularly check for signs of wear, such as elongation or bent pins, and replace them promptly.
