Making cable tray bends is now very simple

Creating bends in cable trays is now straightforward, cost-effective, and can be done on-site with minimal tools.

Types of Bends

Cable trays can be modified to include several types of bends depending on the routing requirements:

• Horizontal 90° Bend (Flat Bend): Used to change direction on a horizontal plane.
• Vertical Bend (Up/Down): Allows the tray to rise or drop vertically.
• Tee (T-Junction) and Cross (4-Way Junction): For branching cable routes.
• Offset Bend (Side Shift): Shifts the tray laterally to avoid obstacles .

Tools Required

For most on-site modifications, you typically need:

• Bolt cutter or cable cutter
• Pliers or nose pliers
• Measuring tape and marker/chalk
• Hand gloves for safety Steel cable trays may also be bent using a metal bar or a simple bending machine if available .

Step-by-Step Process for a 90° Bend

1. Mark the Bend Area: Measure and mark the exact location where the bend is required.
2. Prepare the Tray: For flat bends, remove part of the tray lip using a hand grinder or file to allow smooth bending .
3. Cut if Necessary: Use a bolt cutter to make precise cuts for tees, crosses, or offsets. The cut ends remain protected, and rubber caps can be added for safety .
4. Bend the Tray: Apply controlled force using pliers, a metal bar, or a bending machine to achieve the desired angle. Ensure the tray does not deform or open unexpectedly .
5. Secure the Bend: For flat 90° bends, bolt the two parts together and add a gusset if needed to maintain structural integrity .

Advantages

• On-Site Flexibility: Bends can be created without pre-fabricated fittings.
• Cost-Effective: Reduces the need for additional accessories.
• Quick Installation: Wire mesh trays, in particular, allow fast modifications directly at the project site . By following these methods, installers can achieve professional cable routing efficiently, even without prior experience, making cable tray installation faster and more adaptable to complex layouts.
