1. Vertical Lifting in Sewers and Manhole Confined Spaces

● Pain Point: Traditional single-point dorsal fall arrest lanyards can cause workers to tilt forward or become wedged sideways in narrow openings (manholes) when lifted vertically, delaying critical rescue time.

● Professional Solution: The 1231460 distributes tension evenly to both shoulder D-rings via the spreader bar, keeping personnel in a perfectly "upright vertical" posture during lifting, allowing easy passage through narrow pipe openings.

2. High-Risk Maintenance in Petrochemical Storage Tanks and Large Boilers

● Pain Point: In the event of oxygen deficiency, toxic gas leaks, or other emergencies inside a tank, external rescuers struggle to enter quickly, and pulling the victim out easily causes secondary fractures.

● Professional Solution: With the 1231460 lanyard pre-attached to both shoulders of the full body harness, an external tripod or davit arm can connect in seconds via the central D-ring, stabilizing and vertically lifting the person away from the hazard in minimal time.
