Horizontal cable tray hoisting support

Horizontal cable tray support hoisting uses hoisting frames or cross arms with suspension rods to securely mount trays from ceilings or overhead structures.

Key Components

Hoisting Frames: Ideal for small-sized cable trays, hoisting frames are cost-effective and easy to install. Each frame typically includes a suspension rod and a set of fastening accessories. The recommended installation ratio is one hoisting frame per 1.

5 to 2 meters of cable tray, ensuring adequate support and stability. Cross Arms: Designed for large or heavy cable trays, cross arms provide enhanced stability and facilitate maintenance. Each cross arm requires two suspension rods and two sets of fastening kits, with the same 1.

5 to 2 meters spacing guideline. Suspension Rods (Lead Screws): These vertical connectors link the ceiling or overhead structure to the hoisting frames or cross arms, supporting the tray's weight and maintaining alignment.

Installation Procedure

Positioning: Thread the upper hex nut onto the all-thread rod approximately 203 mm (8") above the desired tray bottom location. Clamping: Place the clamp around the tray siderail, followed by a washer, then lift the tray so the rod passes through the clamp holes. Securing: Add a second washer and hex nut, then adjust the tray to the desired elevation.

Tighten the nuts to secure the tray in place. Double Tray Support: For adjacent trays, use double ladder hanger clamps (DC) to support both trays simultaneously, ensuring proper alignment and load distribution.

Additional Considerations

Load Capacity: Maximum support per hanger ranges from 318 kg to 340 kg, with a maximum spacing of 3. 6 meters. Seismic Bracing: For areas prone to earthquakes, seismic bracing can limit displacement and vibration, protecting cable trays and other electromechanical pipelines.

Wall-

Mounted Options: Horizontal trays can also be mounted against walls using brackets, with larger brackets requiring multiple sets of expansion joints for stability.

Summary

Horizontal cable tray hoisting ensures safe and efficient cable management by using hoisting frames for small trays and cross arms for larger trays, supported by suspension rods and proper fastening kits. Correct spacing, load considerations, and optional seismic bracing are essential for long-term stability and compliance with installation standards.
