N1 Cable Ladders

Cable Ladder

Ezy Strut manufactures a comprehensive range of cable ladder sections suitable for a variety of applications from light industrial to heavy mining installations.

Offered in three levels of performance – light, medium and heavy duty – the range of mild steel, stainless steel and aluminium cable ladders are carefully constructed using precision roll formed steel or extruded aluminium longitudinal side rails together with transverse perforated rung sections.

During the manufacturing process each side rail is pre punched with splice fixing holes to provide easy on site installation. The components are then assembled into purpose built manufacturing jigs where each rung is carefully welded to the side rail section. 

The cable ladder range is available in the following levels of protection

• Hot Dip Galvanised to AS/NZS 4650
• Stainless Steel to AS1449/AS2837
• Aluminium to AS/NZS 1866

Design and Deflection 

Ezy Strut cable ladder sections are designed and manufactured to achieve the loading requirements of the NEMA publication (National Electrical Manufacturers Association) and are available in various load and span performances from Nema 8 up to Nema 20.

A sample of each section has been tested and certified by a NATA approved facility, ensuring that we continue to provide the benchmark in product performance.

All reported results are based on uniformly distributed static loads. 

Whilst NEMA publication does not specify a limitation on deflection, a guide to deflection is included in our technical section for easy reference.

All cable support deflections pertain to continuous cable support systems and do not take into consideration simply supported or end bay sections.

It should be noted that the positioning of splice joints and loading techniques can significantly impact upon the actual deflection. Refer to Nema VE2 installation guidelines for further information.

Special consideration should always be given to live loads resulting from cable pulling to ensure this does not exceed the static cable support load limit.

All load results detailed in this section have been derived from testing 600 wide sections of mild steel, and aluminium cable ladders in the various configurations.

Fire Rated Cable Supports 

Ezy Strut can offer a wide range of cable support systems tested and certified to comply with the requirements of AS/NZS 3013.

Through a commitment toward continual improvement, certification has been achieved on an extensive range of products capable of longer spans and greater working loads.

Setting the standard in fire rated cable support technology, Ezy Strut is constantly chosen for many of Australia largest specialised construction projects, including Australia’s longest road tunnel.

Specific installation methods must be followed to ensure compliance.

Certification is available on the following systems – 

• Nema 1, 2 + 3 mild steel cable ladders
• Ezytray
• ET3 + ET5
• Perforated cable tray
