need to get unravelled by frayed cable ends. Loos electrically cuts mechanical
cable at high speed, fusing all end wires together, saving you time, reducing
waste, cutting inventory, and greatly improving your product. Loos also
offers mechanically cut cable for both plastic coated and bare cable.
cut to your tolerance on precision production machines that cut true at
high speeds.

STRETCH:
STRUCTURAL AND ELASTIC
|
| In your particular application stretch may be a concern There are two forms of STRETCH in cable and wire rope.There is structural stretch which is the lengthening of the lay in the construction as wires adjust under load. Structural stretch in Loos and Co. products is less than one percent of the | length.
This can also be removed completely in a prestretching operation if necessary. The second form of stretch is ELASTIC. Elastic stretch is the actual physical elongation of individual wires under load.The elastic stretch can be determined as follows: |
| E=[W/D2] * G |
| WHERE: |
E
|
= | Elastic stretch, % of length. | ||
|
W
|
= | Weight of load, pounds. | |||
|
D
|
= | Diameter of cable or wire rope, inches. | |||
|
G

= | See chart below. |
