The cable tray cannot be turned at corners

Cable trays can be turned at corners using adjustable or elbow fittings for physical installation, or by assigning and rotating tray elements in software like Revit. Physical Installation Solutions1. Adjustable Corner Pieces: For horizontal cable trays, adjustable corner pieces (like the SRS type) can be inserted into the tray and secured with screws.

These allow a range of angles, typically from 0° to 75°, enabling smooth turns at corners without cutting or bending the tray itself. 2. Elbow Joints: Elbow joints (RVS type) can be used to change the horizontal orientation of a cable tray, with a range from -90° to +90°.

These are pushed inside the tray and attached with screws, providing a secure and structurally sound corner connection. 3. Vertical or Complex Turns: When trays need to change elevation or run vertically, special vertical fittings or racks may be required.

Standard horizontal trays turned on edge can create issues with cable support, heat dissipation, and labor-intensive installation. Using purpose-built vertical cable racks is recommended for safety and efficiency. Software Modeling Solutions (Revit)1.

Load and Assign Fittings: In Revit, cable trays may fail to connect at corners if the appropriate fitting families are not loaded or assigned. Even if loaded, they must be explicitly assigned to the tray system to allow automatic connection at angles like 90°. 2.

Adjusting Vertical Trays: For vertical cable trays, Revit may not correctly orient the tray because vertical lines lack a clear “normal” direction. A workaround is to slightly slant the line or adjust the curve normal to match the desired rotation. Custom scripts or functions in tools like MEPOver can automate this adjustment.

Best Practices

Always use fittings designed for the specific tray type and orientation. Avoid turning horizontal trays on edge without proper vertical support, as this can compromise cable integrity and heat dissipation. In software, ensure all connectors and fittings are loaded and assigned, and check the orientation of vertical lines to prevent misalignment.

By combining the correct physical fittings and proper software configuration, cable trays can navigate corners safely and efficiently.
