Abstract
A hanger loop of rope material provides for the suspension of innumerable articles in various industries, but is particularly well suited for use in underground mining, where it may be used to support electrical cables, pneumatic and hydraulic lines, air ventilation ducts, etc., above the floor of the mine drift. The hanger loop is preferably formed of a braided synthetic fiber which has been treated to provide flame retardant properties and which is also electrically non-conductive. Treated, braided polypropylene is a suitable material for the present rope loop. The closed loop is formed by passing the first end of the rope diametrically through its opposite end portion, and then coaxially through that same portion to secure the first end therein and to form a smaller closed loop. The second end is then inserted coaxially into the body of the main loop to secure the second end within the body of the main loop. This construction results in a braided rope loop in which the interconnected portions are pulled more tightly and securely together when tension is applied to the loop, thus producing a more secure loop which cannot slip when tension is applied. One or more article supports …
