GINDIN: продукция Drumet (Друмет) в России

Principle of construction of a non-rotating rope. What means a compacted rope? Compacted ropes are made of strands, which subject to compaction operation in the production process. Production of the compacted strand comprises drawing the conventional strand, made of round wires, through the compacting equipment, which may be either a drawing die or special compacting head. In the compacting process, strand wires undergo plastic deformation, the strand diameter is reduced (and, simultaneously, the strand cross-section is filled with metal), and the outer strand surface becomes smoother. The conditions of contact between strand wires and between strands in the rope become better. Comparing with ropes produced of conventional strands, the ropes made of compacted strands feature with higher breaking force, higher flexibility, better contact between the rope and winding drum and sheave grooves, also, their elongation is smaller. Due to thicker outer wires and closed outer strand surface, the compacted ropes are more resistant to corrosion and surface friction. Conventional strand Compacted strand What does it mean swaged ropes? Swaged ropes - there are steel wire ropes having compacted cross section done by full rope hammering. Sometimes such ropes are called hammered ropes or compressed, it is because of way of production. Most important advantage of described ropes is considerable higher resistance against friction of steel wire rope outer surface then standard ropes. Additional advantage is much higher swaged rope breaking load after swaging, in comparison to standard steel wire ropes same diameter.
