In excavators for lifting the bucket and on the traction ice of mining and earthmoving machines, always use the rope GOST 7668 - 80. A variety of rope slings are made from the rope of this GOST for lifting and moving loads. Why are GOST 7668 - 80 steel ropes universally used? The answer is simple, because of its design, thanks to it, the rope is softer than the rope according to GOST 2688 - 80, but it does not cost much more.
