THE ADVANTAGES OF STEEL ROPES FROM PLASTIC COMPRESSED STRANDS

in comparison

with the steel ropes of standard constructions:

 

the increase of durability by 30-40%;

the increase of efforts by 15-20 % due to a more complete filling of space between the wires in the strands;

more high crushing resistance thanks to the compact design of the rope, which leads to increase of service life of the rope in multilayer coiling on the drum;

the increase in the elasticity modulus due to a structural density and more uniform tension of the wires in strands, which leads to lower elongation of the rope;

the increase in the wear resistance of the wires and strands of the rope through the reduction of contact stresses with contact elements (block pulley, pulley, drum);

reduced wear of the pulleys, drums and blocks due to the increased area of contact with the supporting surface of the rope.

 

All of them allow to increase service life of the rope, and significantly reduce its operating costs.
