Significant improvements have been made to the equipment used in load handling and load securement activities. In 1973 it would have seemed unimaginable that years later, synthetic slings with an ultimate break strength of 1,360,777 kgs weighing only 15.62 kgs per meter would be readily available. High performance fibers Kevlar®, Spectra® and Dyneema® are used as strength members for high performance synthetic ropes and roundslings, and crane boom hoist and pendant lines. The use of high-performance fibers has not only improved efficiency but enhanced user safety.
