Long spans are generally caused by the surrounding installation environment or other constraints

The common lengths of long-span cable tray are 3m, 4m and 6m.
Long spans are generally caused by the surrounding installation environment or other constraints.
The height of long-span cable tray is 50mm\ 100mm\ 150mm, and the commonly used thickness is 1.0mm, 1.2mm, 1.5mm and so on. The calculation factors of weight include bridge material, bridge density, bridge specification and bridge thickness.
1.The relevant knowledge points are sorted out as follows: 1. The long-span 2000 national bridge standard stipulates that the span of the bridge is the distance between the midpoints of two adjacent supports, and more than 3 meters is the long span.
In the 2000 national standard, the code name of steel material is G and the code name of aluminum material is L.
In the 2000 national standard, the name of the structural feature of the assembled bridge is the assembled tray, and the code is Z.
In the 2000 national standard, the name of the structural feature of long-span trough bridge is bilateral unperforated pallet, code-named DC.
2. When the bridge spacing cable tray is installed indoors, the short span of the bridge support and hanger is generally 1.5m~2m, and the long span can be 3m, 4m or 6m.
When the cable bridge is installed outdoors, the distance between the outdoor posts is generally 6m.
When the cable tray is laid with multiple layers, the distance between layers is generally not less than 0.3m between power cables, not less than 0.2m between control cables, and the distance between weak current cables and power cables should not be less than 0.5m.
3. Bridge height cable tray hanger should fill in: name + height H + cross pole length L, for example: suspension frame, DK-101-50mm 25 represents the suspension frame suitable for 50x 25 bridge (excluding through wires).
When compiling the pick-up list of the horizontal bracket of the wall, the cable tray should fill in: name + model + length of the bracket + height of the bracket.
For example: "arm (5) JY-TB105,L=200,H=50", (indicates the length of the arm 200mm, the distance between the arm and the wall is 50mm.
4. The thickness of the bridge, such as 200*100mm trough specification, the thickness of the tray is 1.2mm, and the thickness of the cover plate of the bridge can be 1.2mm or 1.0mm.
For example, 400*100mm trough specification bridge, the thickness of the tray is 1.5mm, and the thickness of the cover plate of the bridge can be 1.5mm or 1.2mm.
5. Tray weight and cover plate weight constitute the main weight of trough cable tray, such as ordinary galvanized cable tray specification 100*50mm specification, tray weight 3.67kg per meter, cover plate weight 2.20kg per meter.
The weight of the ladder cable tray is mainly the main weight of the ladder frame, of course, if the cover plate is needed, then its weight should be taken into account.
The main weight of a ladder frame consists of two side plates and seven rungs.
