Saddleback Monitor SBM

The DLM Saddleback is a line tension monitor suited for more delicate cable, including telecommunication cables or large cable where a Running Line Monitor is unsuitable.

The line tension is measured by the cable passing over the chute and deflecting the Load Cell mounted beneath.

As with the Running Line Monitors, the speed or distance of the cable pay out can be measured by the roller arm incorporated within the Saddleback.

All expected line tension ratings are calculated under the assumption that the Saddleback is mounted such that the cable running over the Chute is at 7° (wrap of 166°). Line tensions seen will vary if different mounting arrangements are employed.
