Installation of Roller-Type Cable Trays

Cable tray rollers can be installed quickly and securely by positioning them on the supporting member, tightening the bolt, and locking them in place with underpins or clamps.Step-by-Step Installation1. Prepare the Tray and Supporting Members Before installing rollers, ensure the cable tray is properly mounted and supported according to your project plan. Supports should be spaced appropriately, typically 1.5 to 3 meters apart depending on tray type and load capacity, to prevent sagging and maintain stability . 2. Select the Correct Roller TypeStandard Tray Rollers: Drop onto the supporting member, tighten the bolt, and secure with locking underpins .90-Degree Tray Rollers: Install the first roller on the supporting member, secure it, then drop the second roller onto the first to handle directional changes .Adjustable Tray Rollers: Place on the supporting member, adjust the sliding arm to fit snugly, and tighten the wing nut .Speed Mount Rollers: Insert from the bottom of the tray, angle the clamp side over the rung, and tighten the clamp to secure . 3. Position the Roller Ensure the roller aligns with the cable pull direction. For speed mount rollers, the pull should go from the clamp side toward the front side of the roller . For other types, make sure the roller sits firmly on the supporting member. 4. Secure the RollerTighten bolts or wing nuts to hold the roller in place.Insert locking underpins or clamps in the designated openings to prevent movement during cable pulling . 5. Test and Adjust After installation, check that the roller spins freely and is stable. Adjust the position if necessary to ensure smooth cable movement and prevent kinks or damage during installation . 6. Lay Cables Using Rollers Once rollers are installed, cables can be pulled along the tray efficiently. Use multiple rollers for long runs or heavy cables to reduce friction and strain on the cables . 7. Maintenance Tips Regularly inspect rollers for wear, loose bolts, or misalignment. Replace damaged rollers promptly to maintain safe and efficient cable handling . By following these steps, cable tray rollers can be installed safely and efficiently, ensuring smooth cable pulls and long-term reliability of the cable tray system .
