Making a Y-lanyard with a knotted JANE or PROGRESS ADJUST-I lanyard
Tying one or two knots for attachment to the harness allows the length of each arm to be adjusted as needed.
Warnings
- Carefully read the Instructions for Use used in this technical advice before consulting the advice itself. You must have already read and understood the information in the Instructions for Use to be able to understand this supplementary information.
- Mastering these techniques requires specific training. Work with a professional to confirm your ability to perform these techniques safely and independently before attempting them unsupervised.
- We provide examples of techniques related to your activity. There may be others that we do not describe here.
With JANE 1.5 m or PROGRESS ADJUST-I 2 m
With JANE 2 m or PROGRESS ADJUST-I 3 m
Note: This non-certified setup is done under your responsibility in accordance with the PPE-R / 11.088 regulation, including the execution of the knots and the choice of their placement in defining the arm lengths.
Strength of knotted lanyards:
14 kN on each arm with an overhand knot
18 kN on each arm with a figure-eight knot
As a reminder, the strength of lanyard arms in their certified configuration, with no knot(s):
- Non-adjustable arms certified EN 354: 22 kN minimum.
- Adjustable arms certified EN 358: 15 kN minimum.
Precautions:
- The lanyards must be tied into one of the harness attachment points (see the Instructions for Use of the harness).
- WARNING: if you make a lanyard arm too long, for example tying only one knot in a PROGRESS ADJUST-I 3 m, the end of the lanyard may be out of your reach when the lanyard is taut, requiring you to use it with a dangerous amount of slack.
- WARNING: be sure to follow the Instructions for Use of your JANE or PROGRESS ADJUST-I lanyard, including always staying below the anchor with the lanyard as taut as possible and monitoring the adjuster during use to avoid any accidental unblocking.
