A cable tensioning system including: a body defining a balance point; a cable receiving area having gripping elements configured to grip and bias a cable relative to the cable tensioning system; and a sensor configured to sense changes to a balance of the body about the balance point, wherein the cable tensioning system is configured to maintain the cable within a preset range of tensions.

A yarn tensioner is adapted for adjusting tension in a running yarn. The yarn tensioner has a base, an adjustable pin rack, a fixed pin rack, and a fastener assembly. The adjustable pin rack is carried by the base and incorporates a first plurality of spaced apart parallel friction pins. The fixed pin rack is carried by the base and incorporates a second plurality of spaced apart parallel friction pins residing alternately between the friction pins of the adjustable pin rack. The running yarn travels across the yarn tensioner by snaking over and under adjacent parallel friction pins of the adjustable pin rack and the fixed pin rack. The fastener assembly attaches the adjustable pin rack to the base, such that the adjustable pin rack is movable relative to the fixed pin rack, thereby controlling frictional drag on the running yarn.

The cable grab safety device releasably attaches a workman's safety lanyard to a steel cable. A primary frame constructed of an elongated U-shaped bracket having a pair of spaced apart parallel side plates fits around the cable. A secondary frame also comprised of a pair of side plates fits within the U-shaped bracket after the cable is inserted. The secondary frame carries a brake in the form of a pulley mounted in an elongated slot movable toward or away from the cable. A lever attached to a worker's lanyard moves the pulley only in the inward direction to engage the cable in the event of a fall. A bent pin connected between the primary and secondary frames allows for limited pivotal and axial movement between them allowing the cable to be inserted into the U-shaped bracket. A separate locking pin secures the frame members together.
