1、Test purpose

A person attached to a horizontal lifeline may cause himself a long-distance sliding and 

large swing when falling down at a high position, resulting in personal injury.

The purpose of this test is to measure the sliding distance and swing range of the person, 

impact force to him, the strength of the slider when he is falling down from a high position 

above the attached ASAT horizontal lifeline, so as to evaluate the possible injury to the person 

in practical application.

2、Setting up of horizontal lifeline

The horizontal lifeline is set up at a position 4.5 m above the ground. The lifeline is anchored 

on a wall; its double wire ropes are parallelly arranged one above the other; the anchor span 

of the lifeline is 6 m; its end anchors are fitted with shock absorber rings and the double wire 

ropes are properly tensioned.

Slider Feature: Side positioning roller slider (designed to prevent long distance sliding along the

 lifeline)

3、Test procedure

Connect a weight of 100 kg to the slider with a dynamic rope of 2 m. lift the weight 2.5 m up 

(about 0.5 m higher above the lifeline), and about 0.3 m of horizontal distance from the lifeline.

At the beginning of the test, the distance between the slider and an end anchor is 0.8 m.

4、Test data

After the weight of 100 kg is released:

The shock absorber rings on the anchors of both sides slip to absorb the shock; the shock absorber

 components of the system have reasonable slippage as designed.

The sliding distance of ASAT side positioning roller slider on the lifeline is 49.5 cm, and the horizontal 

swing range of the weight is within 71 cm, so such horizontal movements shall not cause personal 

injury.

In the case the drop distance of the slider is 0.7 m (vertical drop distance of the lifeline).

The impact force is less than 6 kN.

There is no obvious deformation on the slider and lifeline components.

5、Conclusion 

The person falling down from a high position above the attached ASAT horizontal lifeline will not cause

 him a long-distance sliding along the lifeline, so as not result in personal injury.
