Open Type Cable Carriers

Open Type Cable Carriers & Bridge Drag Chains for Automation Machinery

Welcome to our specialized lineup of open type cable carriers (also widely referred to as bridge type drag chains, open style cable tracks, hinged energy chains, or open plastic towlines). Precision-molded from high-tensile glass-fiber reinforced polyamide (PA66), our open-bridge cable carriers provide flexible, smooth, and dependable dynamic guidance for electrical cables, pneumatic hoses, servo lines, and hydraulic pipes. Designed specifically for high-speed automated equipment where rapid heat dissipation and effortless cable lay-in are essential, these open carriers deliver superior mechanical stability and extended service life.

Key Advantages of Open / Bridge Type Drag Chains

Open-structure cable carriers are the most versatile and widely utilized solution across automated manufacturing industries due to their distinct practical benefits:

• Fast & Easy Cable Installation: Featuring snap-open crossbars along both the inner radius (R) and outer radius (R), technicians can quickly insert, inspect, or replace individual cables and hoses without dismantling the entire chain or disconnecting electrical terminals.
• Superior Heat Dissipation & Air Circulation: The open frame construction allows continuous airflow around dynamic power cables and high-pressure hoses, preventing thermal buildup during continuous high-frequency reciprocating movement.
• Lightweight Design with High Load-to-Weight Ratio: By eliminating solid protective covers, open bridge carriers reduce moving inertia and motor driving torque requirements, enabling higher acceleration rates and faster machine cycle times.
• High Wear Resistance & Low Operating Noise: Engineered hinge link mechanisms and precision joint tolerances ensure quiet articulation, reduced surface friction, and smooth travel over long stroke distances.
• Modular Dividers & Separator Systems: Can be fitted with vertical dividers and horizontal shelving to organize multiple cable types, preventing internal twisting, friction abrasion, and conductor fatigue.

Structural Options & Configurations

To match different mechanical designs and machine layouts, we supply a wide range of open cable carrier configurations:

1. Snap-Open Crossbars on Both Sides: Crossbars swivel open or fully detach from either the inner radius or outer radius, providing maximum operational convenience during assembly and maintenance.

2. Hinged / Pivot Open Design: Crossbars unlatch on one side and swing open on a hinge, ensuring that crossbars stay attached to the carrier body so they are never misplaced during field servicing.

3. Fixed Crossbar Bridge Chains: Designed with permanent crossbars for compact, low-cost machinery where cables are fed through from one end during initial equipment build.

4. Heavy-Duty Supported Open Carriers: Reinforced side link construction designed for long unsupported lengths, high acceleration rates, and heavy hose payloads.

Technical Sizing & Selection Guide

To select the ideal open type drag chain size for your system, keep these core engineering criteria in mind:

1. Inner Height (Hi) & Inner Width (Bi): Ensure internal clearance dimensions exceed the maximum outer diameter (OD) of your largest cable or hose by at least 10%–15%.
2. Bending Radius (R): Choose a bending radius based on the minimum bend radius specification of your cables (typically 8x–10x outer cable diameter) to avoid premature internal core wire failure.
3. Travel Distance & Mounting Ends: Determine required chain length using standard stroke formulas and specify end brackets with integrated strain relief combs to anchor cables securely at both fixed and moving ends.

Broad Industrial Applications

Our open type plastic energy chains are extensively applied across a diverse range of high-tech and general manufacturing machinery, including 3D printers, CNC routers, automated pick-and-place systems, gantry robots, packaging equipment, textile machinery, electronics assembly lines, and warehouse logistics automation (AGV/AMR). As an established direct factory manufacturer, we provide complete engineering assistance, custom CAD/STEP models, specialized mounting brackets, and competitive wholesale pricing.

Frequently Asked Questions (FAQ)

Q: When should I choose an open type cable carrier instead of an enclosed type?
A: Open type carriers are preferred when your machinery operates in clean to moderate environments where rapid heat dissipation, lighter weight, visual cable inspection, and quick installation are priority factors.

Q: Are your open drag chains compatible with standard mounting dimensions?
A: Yes, our open series dimensions, link pitches, and bracket mounting patterns are standardized to offer seamless replacement for major international brands at direct factory cost.
