➜ Lesson 01:
Correct transport of rope reels
Transporting and unloading wire ropes with care
Learn how to transport and store verope special wire ropes correctly.
The handling of wire rope reels requires a certain degree of caution. The reel should therefore be unloaded from the loading area either by means of a fork lift, where the reel is lifted by means of a sufficiently dimensioned shaft as attachment points for the forks, or by means of an overhead crane as described in the picture below. The wound reel of wire rope should be moved as described before. Reels can easily be knocked over by the forklift which may damage both the reel and wire rope, so it is not advisable to do so.
Technical facts about special wire ropes

Composition of a special wire rope
Every part that makes our ropes special
By the design of a wire rope, one understands the formation principle according to which the elements of the wire rope (the wires and the strands) are arranged relative to each other. The designation of a fiber core is FC, for an independent steel wire rope core it is IWRC. As an example all round strand ropes of the 6×19 Warrington design with a fiber core have the construction 6 x [1-6-(6-6)] – FC.

Fill factor of a strand
what the fill factor number means
The fill factor of a strand is defined as the ratio of the metallic cross section (or as simplified calculation the sum of the single wire cross sections) related to the area of the smallest circle enclosing the strand. The fill factor specifies the amount of space which the strand takes in the rope meaning the quantity of steel. The fill factors of the most common strands are between 0,70 and 0,82. This means, that the amount of steel in the strand is about 70% to 82%. The fill factors of strands can be considerably increased by compacting. Usually the fill factor of a strand increases with an increasing number of wires. A Seale 15 strand (1-7-7) for example has a fill factor of about 0,77 and a Seale 19 strand (1-9-9) has a fill factor of about 0,79.

Lay type of wire ropes
right or left hand lay is important for handling and using the rope
A distinction is made between right hand and left hand lay strands. The lay direction is left hand, when (moving away from the beholder) the wires are rotated counterclockwise. The lay direction of a strand is right hand, when its wires (moving away from the beholder) are rotated clockwise. The lay direction of a strand is often given by small s for the left hand lay strand and by a small z for the right hand lay strand.
