Python Wire Rope - Wesco Industries Ltd.

Wire rope is a very complex machinery element which primary function is the
transmission of tensile forces. Its basic constructional design allows repeated
changes in the direction of pull through reeving systems incorporating drums
and sheaves.
General purpose rope constructions are standardized in national (ASTM,
CSA) and international standards (ISO).
However, the increasing demand for higher breaking strength, greater
flexibility, better rotation resistance, and extended rope life cannot be met by
such general purpose rope constructions.
The discrepancy between expectation and operating ‘reality’ has led to the
development of PYTHON® High Performance rope constructions which,
amongst other features, offer significantly improved operating life. This has
been achieved through adaptation of engineered rope geometry and purpose
designed manufacturing processes.
WDI, located in Germany, has taken a leading role in the development of High
Performance PYTHON® Wire Rope as further described in this catalogue.

Wire Rope WILL FAIL if worn-out,
overloaded, misused, damaged, improperly
maintained or abused. Wire rope failure
may cause serious injury or death!
Protect yourself and others:
■ ALWAYS INSPECT wire rope for WEAR,
DAMAGE or ABUSE BEFORE USE.
■ NEVER USE wire rope that is WORN-
OUT, DAMAGED or ABUSED.
■ NEVER OVERLOAD a wire rope
■ INFORM YOURSELF: Read and
understand our literature
■ REFER TO APPLICABLE CODES,
STANDARDS, and REGULATIONS for
INSPECTION REQUIREMENTS and
REMOVAL CRITERIA.
