Fully Enclosed Steel Drag Chains (TLG Series)

Designed to withstand severe operational environments, our fully enclosed steel drag chains (TLG Series) construct an impenetrable 360-degree protective barrier around sensitive electrical wiring, hydraulic lines, and pneumatic hosing. In high-intensity industrial processing where red-hot metal swarf, high-velocity grinding grit, cutting fluid splatters, and molten welding sparks are constantly generated, traditional open-style cable track systems leave internal conduits vulnerable to abrasive destruction. Installing completely sealed metal cable carriers minimizes maintenance downtime, guards against premature hose degradation, and guarantees uninterrupted power distribution across heavy machinery setups.

TLG Series Dimension & Sizing Matrix

The TLG product line offers four standardized physical platforms designed to fit precise internal load parameters and structural space constraints. Review the comprehensive dimension matrix below to identify the ideal pitch, inner/outer height, and bend radius profiles for your equipment design:

• TLG75 Series: Compact sealed architecture engineered for space-constrained CNC turning lathes, automated tool changers, and compact machine tool enclosures.
• TLG100 Series: Mid-sized enclosed track delivering optimal load balance for multiple hydraulic supply lines and dynamic electric feed cables.
• TLG125 Series: Heavy-duty sealed carrier constructed for heavy machining centers, floor-type horizontal boring mills, and long-travel gantry systems.
• TLG175 Series: Maximum-capacity steel cable carrier tailored for large-bore hydraulic hosing, heavy mining machinery, and metal smelting plant installations.

Travel Distance Capacity: Every model within the TLG framework supports unsupported self-supporting travel spans of up to 32 meters without noticeable sag. When equipped with auxiliary support rollers, guide channels, or upper-run trolley systems, operational travel distances can be expanded up to 40 to 50 meters.

Structural Configurations & Material Options

To meet diverse mechanical specifications and severe environmental demands, each enclosed steel cable carrier can be custom-configured:

• Robust Metallurgy: Precision-crafted from cold-rolled structural carbon steel or high-grade stainless steel (SS201, SS304, SS316) to withstand high mechanical impacts or chemical corrosion.
• Custom Internal Layouts: Configured with aluminum alloy or stainless steel cover plates, paired with adjustable internal dividers and rubber-lined separators to prevent cable friction and binding during operation.
• Protective Surface Finishes: Finishing options include Hot-Dip Galvanizing, Electro-Galvanizing, Yellow Zinc Plating, and Electrophoretic Black Coating for severe weather, salt mist, and moisture exposure.

Primary Application Environments

TLG series enclosed metal drag chains provide critical protection across harsh industrial sectors:

• CNC Metal Cutting & Machining Centers: Complete barrier against flying high-temperature metal turnings and coolant fluid spray.
• Steel Mills & Foundry Equipment: Shielding internal conduits against direct thermal radiation, airborne slag, and molten sparks.
• Heavy Forging & Hydraulic Presses: High impact resistance against physical shock loads and falling mechanical debris.
• Port Cranes & Outdoor Material Handling: Sealed protection preventing rain, dust, and corrosive maritime moisture ingress.
