Non-Rotating Wire Rope
Python ® Lift
High Strength Non-Rotating
3-layer type, refer
to page 10
Python® Lift
15 OVAL shaped outer strands
Compacted rope design for highest breaking strength
Outer strands have 5 wires to enhance abrasion resistance plus each strand has
an inserted aluminum buffer core
Inner strands are reversed lay to provide excellent non-rotating properties
Main Applications:
Main- and auxiliary hoist line for high performance mobile-lattice
boom- and for all types of construction tower cranes which require
a super high strength rotation resistant rope construction. This is
THE true NON-ROTATING rope construction.
Rope Characteristic:
This 3-layer rope is constructed from 15 unique oval shaped outer
strands over 24 alternating diameter sized inner strands. The outer
strands of Python ® -LIFT have 5 wires instead of the usual 7. Each
wire is slightly larger for better abrasion resistance. In the inside of
each of these strands we put a aluminum wire during
manufacturing; this aluminum wire has NO function once the rope
is in service.
Python® Lift is our strongest non-rotating rope construction, both in
terms of strength with fixed AND with the ends allowed to rotate
freely. The gain in strength compared with the same sized 19x7 is
an astonishing 60%.
Python® Lift ropes are used where high fatigue resistance coupled
with high strength and excellent non-rotating properties is required;
e.g. in tunnel boring projects, subway construction, etc.
However, we do not recommended this rope to be used on smooth
drums. It works best on LEBUS drums with appropriately sized
groove contours.
Python® Lift ropes are classified as NON-ROTATING
YES, Python® Lift ropes can
be used with a swivel at the
end. In fact, we suggest you
use a swivel during
installation and the 'breakin'
period to get the rope
settled. After the break in
period you can lock the
swivel to stabilize the rope.

O.K.
to use
When properly used
Python® Lift is stable
against block twisting. Fleet
angles, small sheaves,
small line spacing, low
block weight will negatively
impact this characteristic.
