The Drag chain, with the model number 1400.038.100 3.5M and part code 1031000021, in a concrete pump truck serves an important function in managing and protecting electrical cables, hoses, and other lines that need to move and flex during operation.

The primary role of the Drag chain is to provide a secure and organized pathway for the movement of cables and hoses within the concrete pump truck. It is designed to accommodate the dynamic nature of the truck's movements, allowing the lines to extend and retract while maintaining proper alignment and protection.

The Drag chain is typically constructed using durable materials such as steel or reinforced plastic. It features interlocking links or segments that form a flexible chain-like structure, capable of bending and flexing in different directions.

By enclosing and guiding the cables and hoses, the Drag chain helps prevent tangling, twisting, or damage that could occur due to uncontrolled movement. It ensures that the lines remain properly routed and protected, reducing the risk of electrical or fluid leaks, abrasion, or entanglement.

Moreover, the Drag chain helps to maintain the overall cleanliness and organization of the concrete pump truck. It keeps the cables and hoses contained within a dedicated pathway, preventing them from obstructing other components or becoming entangled with surrounding structures.

Additionally, the Drag chain contributes to the safety and reliability of the concrete pump truck. It reduces the potential for tripping hazards by keeping the lines neatly organized and out of the way. It also helps to extend the service life of the cables and hoses by minimizing wear and stress caused by uncontrolled movement or exposure to external elements.

The part code 1031000021 corresponds to a specific Drag chain with the model number 1400.038.100 3.5M, indicating its compatibility and proper fit within the concrete pump truck.
