Steel Conveyance Chain Introduction

Steel cable carriers are mechanical devices used for protecting cables, oil pipes, gas pipes, and other conduits in industrial equipment. They feature high strength, wear resistance, and low noise, and are widely used in CNC machine tools, automated machinery, and other fields.

Definition and Key Features

Steel drag chains originated in Germany, primarily composed of chrome-plated steel chain plates, extruded aluminum alloy support plates, and alloy steel pin shafts. They are designed for modular protection of pipelines against friction, bending, or external damage. Core functions include:

1. Protection Performance: To prevent cable and oil pipelines from wearing or deforming during reciprocating motion, the bending radius should be ten times the diameter of the pipeline (e.g., 50-800mm).

2. Durability: Maximum travel speed of 40 meters per minute, safe lifespan of ≥1 million reciprocations, and operational noise ≤ 68 decibels.

3. User-Friendly Design: Each link can be individually activated, facilitating quick installation and maintenance, and manages multiple pipeline specifications with separator plates.

Categories and Specifications

‌1. Structure Type:

Bridged: Light load scenario, good ventilation.

Fully enclosed: Dust and water resistant, suitable for heavy loads (such as steel mills, oil platforms).

Semi-enclosed design: Balances protection and cost, with high versatility.

Model and Specifications:

TL Model (Basic): Spacing 45-250 models (e.g., TL45, TL125), bending radius 50-500mm.

TLG Model (Enhanced Version): With a higher load-bearing capacity, the free suspension length reaches 10 meters, and the bending radius is 100-600mm.

3. Key Parameters:

Width: 60-1000mm ( widths over 300mm require additional width specifications).

Support Plates: Solid (for heavy loads), Split (for easy maintenance), Framed (for multiple pipelines).

Application Scenario

1. Industrial Machinery: CNC machine tools, robots, cable and hydraulic pipe protection, reducing failure rates.

2. Re-loading Field: Offshore oil platforms, metallurgical equipment, require fully enclosed drag chains for corrosion resistance.

3. Transportation and Energy: Rail transit, ship pipelines, TLG type supports long-distance (≤40 meters) protection.
