Cable Tray Support: An Essential Part of Modern Infrastructure

Cable Tray Support: An Essential Part of Modern Infrastructure

Lachlan Rampling |


The efficient and seamless operation of communication systems has become a central need for all modern infrastructure. Helping businesses maintain this functionality efficiency is greatly dependent on cable tray support. By keeping cables organised, protected and routed throughout facilities correctly, cable trays can help maintain order in a variety of different industries. In this article, we’ll examine the types, installation and maintenance of cable trays, examining innovations and challenges that this innovation faces.

What is a Cable Tray?

Used in an array of different infrastructural settings, a cable tray is a resilient framework that manages and supports the electrical cables of a business. Designed to create secure, efficient routing, there are different types of cable trays to serve different requirements.

Ladder Cable Trays

Ideal for installation situations where heat is generated, ladder cable trays are designed to provide high levels of ventilation and visibility for cables, with two side rails that are connected by rungs.

Trough Cable Trays

Coming with both ventilated or solid bottoms, trough cable trays focus on the protecting of cabling while still providing the option of limited ventilation.

Channel Cable Trays

A great solution if trays need to be installed in confined locations, channel cable trays are a great option if you have moderate quantities of cables that require infrastructure.

Wire Mesh Cable Trays

An ideal design for routing paths of greater complexity or the installation of data cables, these cable trays, as the name suggests, are wire mesh, making them a superior option if flexibility and weight are factors in your infrastructure.

Why Cable Tray Support is Crucial

It's impossible to overstate just how important cable tray support systems can be in relation to maintaining the integrity of a system. Here are some key issues than can occur from inadequacies in your cable tray support system:

Cable Damage

Sagging, twisting or crushed cables are all hallmarks of poorly supported cables. This can lead to the damage of cable insulation and, eventually, the possibility of short circuits.

Safety Hazards

Hazards like tripping are an obvious risk that can occur from poorly supported cables. Apart from the obvious accidents that can occur, this can also lead to problems like system failures, when cables are disconnected or even fire risks.

Operation Inefficiency

Troubleshooting and maintenance can become unnecessarily complex if cables aren’t efficiently organised. This can lead to increased operational costs and company downtime.

Types of Cable Tray Support Systems

Various operational applications require different types of tray support systems. Here are several of the currently available cable tray support systems:

Ladder Support Systems

Easy to install and maintain, ladder support systems are exceptionally strong and well ventilated, making them a great option for heavy-duty projects where bulk is not a concern.

Trough Support Systems

Suitable for medium-level applications, the trough support systems feature solid or ventilated bottoms and provide tough protection with a maintained allowance of airflow.

Channel Support System

Easy to install and taking up very little space, Channel Support systems are ideal for lightweight application in confined spaces. They offer less ventilation than both trough and ladder systems. 

Installation and Maintenance of Cable Tray Support

To guarantee the best results long-term, it is integral to install and maintain cable tray support systems correction. Here is a brief guide to give you an understanding of what is required:


The central criteria for selecting the correct cable tray and support system is the assessment of your layout and your load requirements.


Mount all support brackets to the structure securely, making sure they are suitable to bear the cable loads.


Connect all section securely and be sure to assemble all cable trays according to instructions.

Cable Laying

Be sure to maintain even weight distribution to avoid excessive bending by laying the cables neatly within the trays.


Prevent movement by using the correct ties and fasteners to secure cables with the trays.

For maintenance:

Regular Inspections

Be sure to inspect the cable tray supports systems on a regular basis, looking for corrosion and signs of wear and tear.


Rigorously maintain the cleanliness of arrays by making sure to dispose of debris and dust, to maximise tray ventilation and avoid fire hazards.

Tightening Connection

Vigilantly check cable tray connections, making sure they are all fastened tight and that sagging and displacement are not occurring.

Common Challenges and Solutions

Several challenges can occur during maintenance procedures:

Space Constraints

Confined spaces can make maintenance a challenge. Channel or wire mesh trays are the best options for these situations.

Load Management

Structural failure can be caused by overloading trays. To avoid this, be sure to perform a load calculation and select more heavy-duty trays, if necessary.

Environmental Factors

Corrosion can occur in some environments. Be sure to check for wear and consider corrosion-resistant materials like fibreglass and stainless steel in applicable locations. 

Innovations in Cable Tray Support

Technology continues to roll forward to improve efficiency and safety. Cable tray support systems are no different. Here are some recent innovations:

Modular Systems

Modular cable systems provide greater flexibility in cable tray systems, allowing for expansion and reconfiguration whenever it is required.

Smart Monitoring

Further steps to prevent failures and enhance maintenance can be provided by smart monitoring through sensors that test for load, temperature and a variety of other parameters. 


Providing correct cable tray support is integral to the efficiency of a variety of different systems when it comes to modern infrastructure. Strong, practical support systems allow you to improve safety, reduce maintenance and can provide smoother operations.
