When the cable tray vendors crosses with the electrical equipment, the net distance between them is not less than 0.5m

When the cable tray enters the building from the outside, the outward slope of the cable tray shall not be less than 100.
When the cable tray vendors crosses with the electrical equipment, the net distance between them is not less than 0.5m.
Bridge support point.
Such as post, bracket or non-standard support, spacing of frame, installation mode, model specification, elevation, may agree to be listed on the plane, or can be marked by different sections, single lines or large sample drawings.
According to the cable tray manufacturer, the bending distance of concentrated load and uniformly distributed load is converted according to the condition that the maximum bending distance is equal: if the maximum bending distance is equal to p / 4=q2 / 2, the bending distance of q2=2p/ / P=90kg will be reduced to 180 / min.
In the formula: Pmurmel 1 person's kg load-1 branch.
Brace spacing (maximum if fulcrum spacing is not equal) (m) equivalent uniformly distributed load (kg/m) of Q2Murtel 1 person according to the above preliminary determined bridge type, specification and fulcrum spacing, consult the sample data of the bridge manufacturer, and repeatedly check the spacing and bridge type until the load requirements are met.
At present, there is no clear stipulation on how to determine the deflection of the cable tray, and it is obvious that reducing the winding should be considered in the heavy load area, which means that the amount of steel will increase correspondingly. Therefore, as long as the maximum allowable stress of steel is fully utilized in the calculation, and a sufficient safety factor is ensured, the ratio of maximum deflection to span (distance between support points) is generally appropriate.
The position and mode of the leading point of the cable tray.
Generally speaking, a large number of cables can be led by vertical bending plate and vertical lead up to the shelf, a small number of cable tray vendors can be led by guide plate or guide pipe, indicating the way of guide.
Special parts such as vertical bending plate, turning plate and so on need to be counted separately.
