Is it ok to connect with textiles elements to the attachment holes on a Hitch Climber pulley? My personal view is that it depends on the situation. For example, if the attachment hole has developed burrs from loading with a karabiner, then textiles elements are likely to be unhappy. If however, the surface of the hole is smooth and free of angled/sharp/abrasive surfaces, small diameter cordage or narrow webbing might be an acceptable choice. The bend ratio created by the side plates may not be sufficient for larger diameter cordage and wider webbing may be unduly compressed in the relatively small diameter holes.
The Hitch Climbers Guide limits the direct connection of textiles because the document discusses a set of defined configurations that have been independently verified to meet the CE certified performance criteria. There are certain conflict situations which can arise when rope is directly connected to the attachment holes, hence the images in the misconfigurations section. These conflict situations may have nothing to do with system strength, but make system function less reliable. To my knowledge, no configuration that involves direct connection of textiles has been tested for static or dynamic strength by the manufacturers of CEClimb, in part because this would limit the climber’s work positioning options and efficiency so dramatically.
The difficulty with making statements like these is that each and every configuration will yield different results during testing. Therefore, it is really down to the end user suggesting a new configuration to ensure that reliable testing takes place, defining the cordage, connectors, knots etc etc.
I have to agree with Taylor, a Revolver is not the correct tool for the top of a V-Rig. In this location the less friction the better, so a high efficiency pulley would be a good choice.
Hope this waffle helps in some way.
