WLL and Design
Factor
Unirope® synthetic slings are manufactured to ensure a design factor
of 5:1. This design factor is a factor which is divided into the nominal
strength of a sling to arrive at the WLL (or Rated Capacity). This factor
is necessary to allow for wear, abrasion, damage, and variations in load
which are not always readily apparent to the sling user BUT DOES NOT
COVER FOR INSUFFICIENT EDGE PROTECTION OR PROTECTION AGAINST CUTTING.
In the absence of a Canadian standard for synthetic lifting slings our sling
capacities meet or exceed the values stipulated in ASME B30.9, and meet
or exceed fabrication efficiencies as recommended by the AWRF.
Continuous testing and quality control guarantee a professionally made and
safe sling. Our test equipment is certfied to ASTM E4 and approved by Lloyd's
Register of Shipping. |

Sling
Tags
Synthetic slings produced by Unirope come with either one of the following tags:
Tag and User Information System
For our Edge-Tech® Nylon Slings the tag is made from heavy duty natural leather, and for our Uni-Web® Polyester Slings the tag is made from custom printed vinyl material.
These tags shows the Rated Capacity for vertical, choker and a 90 degree basket hitches in lbs and kgs, the type of fiber material and the sling length.
In addition, we attach the official WSTDA supplemental warning tag with valuable information for the sling user. The combination of these tags provide the user with the most complete and descriptive information. |
