Powerplast

CASAR Powerplast Wire Rope has a high breaking load and a good resistance against drum crushing. Hoist rope for deck cranes and offshore cranes, pull-in-riser and other applications where rotation resistant ropes are required.

In a CASAR-plast rope, the proportion of plastic to the steel components us thoroughly harmonized in order to fulfill the aspired rope geometry. A plastic coating with a very constant thickness and quality is extruded around the steel core. A thermal after treatment just before the closing of the rope ensures that the outer strands are deeply implanted in the plastic jacket, thus forming plastic edges which separate the strands.

Product Fetaures:

• Temperature range of use: -50 degrees to +75 degrees
• Available in ordinary lay and lang’s lay
• Available in right hand and left hand
• Available in galvanized and ungalvanized

Applications: deck crane, offshore pedestal crane, drilling/piling.

ROTATION-RESISTANT ROPES:

• Designed to generate reduced levels of torque and rotation when loaded.
• Designed with at least two layers of strands laid helically around a centre.
• The direction of lay of the outer strands being opposite to that of the underlying ladder.

Definition: A rotation resistant steel wire rope has a steel core which is an independant rope, closed in the opposite direction to the outer strands. Under load, the core tries to twist the rope in one direction, the outer strands try to twist in the opposite direction. The geometrical design of a rotation resistant wire rope is such that the moments in the core and the outer strands compensate each other over a wide load spectrum, so that even with great lifting heights practically no rope twist occurs.
