Drag chains for tunnel boring machines

Drag Chains for Tunnel Boring Machines

Drag chains play a crucial role in the efficient operation of tunnel boring machines (TBMs). These heavy-duty chains are designed to withstand the extreme conditions encountered during underground excavation. In this article, we will explore the various applications and benefits of drag chains for TBMs.

1. The Importance of Drag Chains

Drag chains are an essential component of tunnel boring machines, ensuring the safe and reliable transport of power, signal, and control cables. By enclosing these cables within a protective chain, drag chains prevent damage caused by abrasion, bending, and twisting. This improves the lifespan of the cables and reduces the risk of downtime due to cable failures.

2. Types of Drag Chains

There are various types of drag chains available for tunnel boring machines, each designed to meet specific requirements. Some common types include:

  • Flexible Chain
  • Plastic Drag Chain
  • Bushchains
  • Plastic Chains
  • Tabletop Chain
  • Multiflex Chain

3. Benefits of Drag Chains

Drag chains offer several benefits that make them the preferred choice for tunnel boring machines:

  • Protection: The primary function of drag chains is to protect cables from external hazards, such as debris, water, and other contaminants.
  • Flexibility: Drag chains are designed to accommodate various cable sizes and configurations, ensuring flexibility in cable routing.
  • Durability: Drag chains are constructed using high-quality materials that can withstand the harsh conditions encountered in tunnel excavation.
  • Easy Maintenance: Drag chains are easy to install, inspect, and replace, minimizing maintenance efforts and reducing downtime.

4. Applications of Drag Chains

Drag chains find extensive use in tunnel boring machines across different applications:

  • Tunnel Construction: Drag chains are indispensable for the successful completion of tunnel projects, providing reliable cable protection.
  • Mining Operations: In mining applications, drag chains ensure the uninterrupted supply of power and signals to mining equipment.
  • Industrial Automation: Drag chains are widely utilized in various industrial automation processes that involve the movement of cables.
