Information
Engineering Design Specification for Steel Cable Tray CECS31:91, editor-in-chief: Electrical Engineering Committee of China Engineering Construction Standardization Association, approved unit: China Engineering Construction Standardization Association.
 
The bridge can contain the following types of construction:
 
1. Perforated tray: It is a groove-shaped member composed of a bottom plate and a side with perforations, or a member formed by punching and bending a whole steel plate.
 
Second, non-porous tray: is a trough-shaped part composed of the bottom plate and the side edges or bent from a single piece of steel plate.
 
Third, the ladder frame: is a trapezoidal component composed of side and several crosspieces.
 
4. Assembled pallet: It is a component that is connected to the pallet by bolts or plugging methods for the perforated parts suitable for any combination on the engineering site.
 
A bend is a rigid, non-linear component used to directly support a cable that can change direction or size and can include the following varieties:
 
1. Horizontal bending: change the components in the direction of the pallet and ladder in the same horizontal plane, divided into 30°, 45°, 60°, 90°;
 
2. Horizontal tee: connect the parts of the pallet and the ladder frame in three directions separated by 90° on the same horizontal plane, and divide and widen;
 
3. Horizontal four-way: connect the parts of the pallet and the ladder frame in four directions separated by 90° on the same horizontal plane, and divide and widen;
 
4. Upper bend pass: the parts that make the tray and ladder frame change direction from the horizontal plane, divided into 30°, 45°, 60°, 90°;
 
5. Bottom bend: The parts that make the tray and ladder frame change direction from the horizontal plane, divided into 30°, 45°, 60°, 90°;
 
6. Vertical tee: connect the components of the pallet and the ladder frame in three directions separated by 90° on the same vertical plane, and divide and widen;
 
7. Vertical four-way: connect the parts of the pallet and the ladder frame in four directions separated by 90° on the same vertical plane, and divide and widen;
 
8. Reducing straight-through: Connect the parts of pallets and ladders of different widths or heights on the same plane.
