AL-309 VL1 Vertical Safety Cable System 15 m
Vertical Lifeline & Guardrail Systems

The PGTEC VL1 is a vertical safety cable system installed alongside fixed vertical ladders on towers, silos, wind turbines, water tanks and industrial access shafts, protecting a single worker as they climb up and down. An 8 mm galvanized steel cable runs the full 15 m height, anchored at the top and bottom with galvanized brackets and guided by navy-blue cable clamps fixed to each ladder rung. A travelling rope grab attached to the worker's harness D-ring rides freely up and down the cable during normal climbing, but locks instantly if a fall begins, arresting the climber on the vertical line before they can slip from the rungs. With a rated system strength above 22 kN and capacity for one 150 kg climber including tools, the VL1 removes the ladder-fall hazard that makes vertical access one of the most dangerous tasks in industry. The cable is tensioned by a bottom-adjustable anchorage, and the rope grab can be disengaged at the top platform to move onto a horizontal system. Supplied as a complete kit with top and bottom anchors, intermediate clamps, rope grab and installation instructions, the VL1 is used by tower technicians, silo inspectors, maintenance crews and wind-farm service teams who climb fixed ladders every day. The PGTEC VL1 is the dependable EN 795 / EN 353-1 vertical lifeline that keeps climbers anchored for every rung of the ascent.
