As with all connectors, the MGOs are made to be loaded on their major axis and are weaker when poorly positioned.
1. Common examples of wrong positioning
Open gate loading
Risk of the MGO disconnecting
Variable strength loss depending on the angle between the axes of loading.
Risks of rubbing on the gate and the release lever:
Risk of the gate opening and of the MGO disconnecting.
Frontal pressure on the gate:
The resistance to frontal pressure on the gate is greater than 1 kN for the CE versions and greater than 16 kN for the ANSI versions.
Lateral pressure on the gate:
The resistance to lateral pressure on the gate is greater than 1 kN for the CE versions and greater than 16 kN for the ANSI versions.
Attachment to an anchor that is too small:
The length of the MGO can create a significant cantilever load with a risk of breaking the MGO or loosening the anchor.
Medium width BAT’INOX-type anchors:
This type of anchor almost allows the MGO 60 to move freely, but is tight enough to create a cantilever load in certain cases (e.g. if the user climbs above the anchor and falls).
2. Cantilever load over an edge
In a work situation, attaching an MGO to an upright is a common necessity. This can create a cantilever load over an edge.
In this position, the MGO must be used with precautions:
– beware of the user’s position relative to the anchor
– With a Y-lanyard be sure to connect both MGO to the anchor
