Correct method for cable tray hoisting

Cable trays can be hoisted using hoisting frames, cross arms, and suspension rods, with installation methods varying by tray size and mounting location.

Hoisting Small-

Sized Cable Trays

For small cable trays, hoisting frames are commonly used. These frames are cost-effective, easy to install, and provide adequate support for lighter loads. A typical setup includes the hoisting frame, a suspension rod for vertical support, and a five-piece fastening kit to secure the tray.

The recommended spacing is one hoisting frame every 1. 5 to 2 meters, each with a suspension rod and fastening kit to ensure stability and prevent sagging.

Hoisting Large-

Sized Cable Trays

For larger or heavier cable trays, cross arms offer a more robust solution. Each cross arm requires two suspension rods and two sets of fastening kits. This method provides enhanced stability and facilitates maintenance, ensuring the tray can safely support heavier cable loads.

The installation ratio is also one cross arm per 1. 5 to 2 meters of tray.

Suspension Rods and Accessories

Suspension rods (or lead screws) connect the ceiling or overhead support to the hoisting crossbars of the tray. They are essential for both hoisting frames and cross arms. Additional accessories include: Threaded rods for ceiling connectionsMounting clamps and tray hangers for extra supportWall-mounted brackets for side supportCable tie mounts to organize cables and prevent slippage Mounting ConsiderationsCeiling-mounted supports are ideal for large areas, keeping trays elevated and accessible.

Wall-mounted brackets work well in confined spaces. Floor-mounted bases may be used where ceiling or wall space is limited. Bracket spacing should generally be 4–5 feet apart, with closer spacing for heavier loads.

Safety and Best Practices

Ensure all materials are approved and inspected before installation. Operatives should be trained and competent in safe hoisting procedures. Inspect the installation area for hazards and correct any unsafe conditions before proceeding.

Use components designed to work together as a system to maintain structural integrity. By selecting the appropriate hoisting method and accessories based on tray size and load, cable trays can be safely and efficiently installed in industrial or commercial environments.
