5. Installation Instructions

The JUM55 Cable Hanger is designed for straightforward installation on messenger wires. Follow these steps for proper attachment:

1. Prepare the Messenger Wire: Ensure the messenger wire is clean and free from obstructions at the desired installation point. Verify that the messenger wire size is within the applicable range of 38 mm² to 55 mm².
2. Position the Hanger: Place the wire frame of the JUM55 hanger over the messenger wire. The two loops of the hanger should securely engage with the messenger wire.
3. Secure the Hanger: Gently press the hanger to ensure it sits firmly on the messenger wire. The design allows for a snug fit without requiring additional tools for attachment to the messenger wire itself.
4. Insert the Cable: Once the hanger is secured to the messenger wire, guide the cable into the soft PVC receiver. Ensure the cable's outer diameter does not exceed the permissible 50 mm. The PVC material will cradle the cable, providing support and preventing damage.
5. Verify Placement: After installation, visually inspect the hanger and cable to ensure they are properly seated and stable.

Note: For optimal performance and safety, distribute hangers evenly along the cable run according to engineering specifications and load requirements.

• Replacement: Replace any hangers that show signs of significant damage, deformation, or material degradation to prevent potential cable support failure.
