Cable tray cover plates can be pressed

Yes, cable tray cover plates can be fixed using a pressing plate method, which secures the cover to the tray through perforation and screws.

Pressing Plate Method

The pressing plate method involves punching holes in the cover plate of the cable tray, then pressing a metal plate onto the cover. The cover plate and the tray are then fixed together using screws through the perforated holes. This method is versatile and can be applied whether the cable tray is installed horizontally or vertically, providing a secure and stable attachment for the cover plate .

Other Common Fixing Methods

1. Screw Fastening: The cover plate is punched, and screws or rotating plates are used to secure it to the tray. Suitable for both horizontal and vertical installations .
2. Buckle Fixing: The cover plate is bent at both ends to form a fold that hooks onto the tray. This method does not require punching but is mainly suitable for horizontal installations, as vertical covers may slip .
3. Padlock Fixing: Provides additional security by locking the cover plate in place, often used in areas requiring restricted access .
4. Seven-Shaped Buckle Fixing: A specialized mechanical hook design that secures the cover plate without screws, typically used for quick assembly or maintenance .

Material Considerations

Cable tray covers are commonly made from pre-galvanized or hot-dip galvanized steel, which ensures durability and corrosion resistance. The choice of material can affect the ease of pressing and the long-term stability of the cover plate .

Summary

Using a pressing plate is a reliable and widely used method for securing cable tray cover plates. It is compatible with various tray orientations and provides strong mechanical stability. Depending on the installation requirements, other methods like screw fastening, buckle fixing, or padlock fixing may also be considered for convenience, security, or aesthetic purposes .
