PMI® EXTREME PRO™
with patented Unicore® construction is a
hardy static rope with a 32-carrier polyester sheath bonded to a nylon
core. Great abrasion resistance, no sheath slippage, and excellent
knotability make this an ideal choice for rescue applications as well as
work at height in harsh environments.
POLYESTER CORE ROPES
PMI® ISOSTATIC
is an all-polyester rope that provides extremely low
elongation and excellent abrasion resistance. Choose PMI® Isostatic for rigging
highlines and for long hauls where minimal stretch is preferred, but keep in
mind that this rope also has less capability to absorb sudden forces and will
transmit the effect of impact loads to anchors and equipment.
ARAMID ROPES
PMI® HEATSHIELD™
is a rope with a 100% Technora® sheath and nylon core.
It features a high tensile strength, good fatigue resistance, heat resistance,
excellent dimensional stability, and chemical resistance.
ABOUT YOUR PMI ROPE
(cont.)
Any system incorporating these life support ropes should include a reliable
anchorage point, compatible equipment, and a means of limiting the demands
on the system to within its capabilities. According to ANSI Z359 anchorage
requirements, an anchorage should be no less than 5,000 lbs. (22.2 kN) for
non-certified anchorages or at least two times the maximum arresting force for
certified anchorages.
These ropes when used as a single anchor lifeline, according to ANSI Z359.15,
can be used with fall arresters designed to be used with kernmantle ropes for
the specific diameter rope that you are using. Elongation percentages when
loaded to a minimum of 900 pounds (4kN) are expressed on the printed label
on the inside cover of these instructions. When using a fall arrester on a single
anchor lifeline the capacity range for single person use should be between
130 pounds to 310 pounds. Users must tie a stopper knot (such as a barrel
knot) or use an appropriate rope stop designed to prevent a fall arrester from
inadvertently traveling off the end of the lifeline.
If a rope section is damaged, the damaged section may be able to be cut out of
the rope. Such a determination must be made by a person competent in rope
inspection to determine whether remaining rope would be safe for use. The cut
ends of the rope should be heat sealed and the inspected rope should be tested
before use at height.
