Using the LADDER CLIMB attachment point on the VOLT harness, European version.
Understanding the use of the LADDER CLIMB attachment point on the VOLT harness, European version.
- 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.
Use in vertical progression along a rail or cable
The LADDER CLIMB attachment point on the 2020 and pre-2020 VOLT harnesses was designed for use in vertical progression along a rail or cable. - The LADDER CLIMB attachment point allows for ventral attachment of the fall arrest trolley: it distributes the load on the waistbelt and ensures optimal comfort during progression, when climbing up as well as down.
In case of a fall, the stitching tears on the LADDER CLIMB attachment point webbing, and the point moves up to a sternal position. This helps give the user a vertical post-fall body position.
Use with ABSORBICA-I or Y lanyards or ASAP mobile fall arrester.
The LADDER CLIMB attachment point on the 2020 and pre-2020 VOLT harnesses is certified EN 361: 2002. So it can be used to attach a fall-arrest lanyard. However, it is important to take into account the elongation of this point (due to tearing) for the clearance calculation.
- 2020 VOLT = 55 cm
- Pre-2020 VOLT = 50 cm
To limit the fall distance, Petzl recommends using the sternal point to attach fall-arrest lanyards or a mobile fall arrester.
On the 2020 VOLT, the stitching on the LADDER CLIMB attachment point webbing is designed to tear in case of a fall and to allow other uses, such as occasional suspension (attachment point certified EN 813: 2008) and work positioning (attachment point certified EN 358: 2018).
On the pre-2020 VOLT, the stitching on the LADDER CLIMB attachment point webbing is designed to tear in case of a fall. So this point is not designed for uses such as suspension and positioning. There is a risk of inadvertently tearing the stitching of the LADDER CLIMB attachment point webbing.
For positioning, use the side attachment points on the harness or the seat attachment points.
