Non-Rotating Wire Rope
Python ® Compac 35 Non-Rotating Wire Rope
3-layer type, refer
to page 10
Compac® 35 (35x7)
16 outer rope strands (19x7 has 12 only)
Compacted rope design
Outer wires are die drawn to provide a smooth rope surface thus enhancing
spooling characteristic (less interlocking on drum)
Inner strands are reversed lay to provide good non-rotating properties of the rope.
Main Applications:
Main- and auxiliary hoist line for european type mobile- and for all
types of construction tower- and offshore cranes which require a
high strength rotation resistant rope construction. The rotation
resistant properties make this rope the preferred choice for all
single- and multiple line reeving applications.
Rope Characteristic:
This rope is constructed from 16 outer die-drawn strands over 12
inner die-drawn strands. The compacted Lang Lay strands reduce
interlocking while spooling onto multiple layer drums as well as
inter strand- and inter layer nicking.
This rope is suited to be used on tower cranes as well as european
made mobile crane models. Python ® Compac 35 comes with a
limited diameter tolerance of between +2% to +4% to comply with
LEBUS drum criteria. The large number of outer strands distribute
the pressures introduced by sheaves and drum more evenly onto
the core minimizing the danger of unexpected rope failures
because of undetected core deterioration.
Aside from this safety issue Python ® Compac 35 satisfies the highstrength
requirements of late model tower- and mobile cranes
which can NOT be met with neither 19x7 nor 19x19 style ropes.
Recommended to be used on grooved drums.
Python ® Compac 35 is available in right- AND left hand lay to
comply with OEM specifications (Krupp, Demag, Liebherr etc.)
Python ® Compac 35 ropes are classified as
NON-ROTATING
YES, Python® Compac 35
ropes can be used with a
swivel at the end. In fact, we
suggest you use a swivel
during installation and the
'break-in' period to get the
rope settled. After the break
in period you can lock the
swivel to stabilize the rope.

When properly used
Python® Compac 35 is
stable against block
twisting. Fleet angles, small
sheaves, small line spacing,
low block weight will
negatively impact this
characteristic.
