Cable tray elbow accessories are generally ordered in the factory, in the field to do the disadvantages of one is not beautiful, two is not durable (especially spraying and hot dip zinc treatment) , three is time-consuming, in particular, some project management is not allowed on-site processing, so usually users in advance according to the construction drawings out a good list, by the factory after the direct installation.

Because it is installed in the process, there are generally three kinds of elbow: a Horizontal Bend, a vertical up and down bend, and a “Zigzag”bend. Shandong Cable Bridge Su Xin told you to make the square cable bridge is actually the solution of the equation, not good math to make out.

Making elbow of the first layer: The method of the two elbows of the first layer is the same as that of the elbows in "1". The distance a between the two elbows is determined on site, but the bend radius of the cable must be met. Make the second layer elbow: calculate the positioning size e of the first elbow of the second layer bridge: first measure the positioning size D value of the first layer bridge, then E = D BTG1/2 α : B is the layer spacing, and the Angle α value is the same as "one" in accordance with the method of "one" to make the first notch α of the second layer elbow; Calculate the spacing c value of two elbows: c=2btg1/2α In formula A: B is the spacing between layers, a is the spacing between two elbows of the bridge of the first layer. The second notch α of the second layer elbow is made according to the method of "one". Calculate the compensation size H: h=2 bTG1/2 α Fabricate the third layer elbow: fabricate the same method as the second layer elbow F = E bTG1/2 α g= 2BTG1/2 α C

You can’t really do it if the math is bad, but you can see here that it takes so many equations to make a bend, not to mention the whole bridge, can Imagine Shandong Cable Bridge Su Xin team is what kind of a group of people.
