Specification:55*50,55*60,55*75,55*100,55*125,55*150,55*175,55*200
Color: Black (Custom colors available upon request)
Opening Method: Side-opening
Structure: Bridge-type / Fully Enclosed
The opening mechanism utilizes a sliding latch design; the unit can be opened simply by lifting the crossbar upward from the side. To close it, press the crossbar downward until a distinct "click" is heard, signaling that it has securely locked into place. Since one end of the crossbar remains permanently anchored to the chain link, it will not become dislodged—even in environments subject to vibration.

Characteristics and Applications of Drag Chains
**Heavy-Duty Gantry Machining Center Beam:** High-altitude operation; the non-detachable crossbars ensure safety.
**Marine Crane Slewing Mechanism:** Marine environments; available with an optional stainless steel shaft for corrosion resistance.
**Large-Scale Heat Treatment Furnace Feeding Mechanism:** High-temperature zones; features a side-opening design to prevent burns to operators.
**Tunnel Boring Machine (TBM) Trailing Gear:** Confined spaces within tunnels; the crossbars are designed to prevent them from falling into equipment gaps.
**Wind Turbine Yaw System:** High-altitude maintenance within the nacelle; the side-opening design offers enhanced safety and reliability.
