Description
ARESTA Life line
20m temporary life line
Adjustable horizontal lifeline static 3 man system – the structural anchor points have to be
situatedon the same level and have minimal static resistance 18kN (1 person),
20kN (2 persons), 22kN (3 persons). Ideal for construction, roofing industry, open trenches, scaffolding and
formwork.
• Protection for up to three users
• Zinc plated and powder coated tensioner
• 19mx35mm polyester working rope
• Snap-lock connectors
• 20m webbing line
• Supplied with Kit Bag.
Horizontal lifelines, depending on their geometry (see diagram) and angle of sag,
subjected to greater loads than the impact load imposed by an attached component.
When the angle of horizontal lifeline sag is less than 30 degrees,
the impact force imparted to the lifeline by an attached lanyard is greatly amplified.
For example, with a sag angle of 15 degrees, the force amplification is about 2:1 and at 5 degrees sag, it is about 6:1.
Depending on the angle of sag, and the line’s elasticity,
the strength of the horizontal lifeline and the anchorages to which it is attached should be increased a number of times over that of the lanyard.
Horizontal lifelines shall have a tensile strength, capable of supporting a fall impact load of at least
5,000 pounds (22.2 kN) per employee using the lifeline, applied anywhere along the lifeline.
