ST95 30kN Double Bollard Rope Grip (pair)

The rope is wrapped around each bollard, once or twice, depending on it’s diameter and then the tail is clamped in a vice. The bollard diameter is 40mm. The vice will accommodate rope up to 8mm maximum. Friction between the bollards and the rope and the initial tension from the vice take the load applied by the tensile testing machine. If testing to BS EN919 then it should be noted that the ratio of bollard diameter to rope diameter should be a minimum of 10:1.

The grip is designed to be loaded as follows. Using the grip illustration opposite, take an anti-clockwise turn round the lower bollard, followed by a clockwise turn round the upper bollard and then into the vice. The turns will be slightly more than 360 degrees on each bollard. The sample must enter the top of the vice as this is curved to avoid chaffing the sample.
