How to move concrete cable trays

Concrete cable trays should be moved using proper lifting equipment, careful handling, and adherence to safety guidelines to prevent damage and injury.

Preparation and Inspection

Before moving concrete cable trays, inspect each unit for cracks, chips, or defects that could compromise structural integrity during lifting or transport. Ensure the site is clear of obstacles and that the path for moving the trays is level and stable. Use timber supports or dunnage to keep trays off the ground and prevent moisture damage while preparing for transport.

Lifting and Handling

Concrete cable trays are heavy and rigid, so manual handling is not recommended. Use overhead cranes, forklifts, or lifting slings designed for heavy precast concrete units. When using slings or chains: Place slings at the center of gravity to maintain balance.

Avoid attaching slings directly to the tray edges or lids, as this can cause cracking or deformation. Lift single units at a time to reduce the risk of tipping or damage. For longer trays, consider spreader bars to distribute the load evenly and prevent bending or stress on the concrete.

Transporting

When moving trays on-site: Use forklifts on level ground and ensure the load is stable. Avoid sudden movements or sharp turns that could shift the load. If transporting by truck, palletize trays or secure them with straps to prevent sliding.

Storage

If trays are not immediately installed: Store them horizontally on flat surfaces with timber supports at regular intervals (approximately 1 meter) to prevent sagging. Cover trays to protect from direct sunlight and moisture, which can affect the concrete surface. Stack trays by size and type to facilitate safe lifting and installation later.

Safety Considerations

Always wear personal protective equipment (PPE), including gloves, steel-toed boots, and hard hats. Ensure qualified personnel operate lifting equipment and follow site-specific safety protocols. Never use the tray itself as a lifting point or attach chains to unsupported edges.

By following these steps, concrete cable trays can be moved safely and efficiently, minimizing the risk of damage to the trays or injury to personnel while maintaining the integrity of the cable support system.
