A towline, selection guide

In 1, high : the choice of the built-in cable, tubing, pipe, pipe, the thick one as a reference height, with a height of at least 10% space as a drag chain of high Hi. If overlapped by overlapping actual height as the reference height.

2, inner width: choose thicker cables, water pipes, tubing, pipe, the outer diameter as the drag chain inside wide reference, and leave it for at least 10% of the width of the space.

3, bending radius : the choice of the built-in cable, tubing, trachea, maximum bending radius range of the reference value, and have more than 10% of the space.

Towline cable, tubing, pipe, built-in tracheal placement principle

The 4, should have 15% of the remaining space, let the built-in cable, tubing can move freely, in the radius direction on chain does not generate tension

In 5, the difference in diameter of wire laying weight should be separated, the mean of the distribution, if necessary separator separates.

In 6, high speed or high frequency operation, we should try to keep the lead level in separay from each other, not to overlap, on cable, pipe, tubing and other more time suggest the use of separator.

In two, the drag chain length and installation height calculation

Drag chain length L = S / 2+pR+P + T （ 2-3 ）

Mounting height is H = 2R+Ha+0.1Ha.

Fixed point in the middle of run （P = 0 ）, the most economical chain length
