Heavy Duty Cable Ladder | 100mm–500mm Wide | 76mm Deep | 3m Standard Length

Heavy Duty Cable Ladders are thick-gauge steel open-rung cable support systems engineered for the most demanding cable management applications in mining, petrochemical, power generation and heavy industrial electrical installations across South Africa. With a deeper rail height and heavier gauge steel construction than the medium duty range, heavy duty cable ladders offer maximum load- bearing capacity and structural rigidity — designed for large power cable bundles, long unsupported spans and harsh environments where standard cable ladders are insufficient. Like all cable ladders, the open rung design provides maximum ventilation around cables — allowing them to run cooler and carry higher current loads than cables routed in enclosed cable trays. This makes heavy duty cable ladders the preferred choice for large power cable installations in demanding South African industrial and mining environments. Supplied in standard 3 metre lengths, available in widths from 100mm up to 500mm to suit any cable volume or installation requirement. When to choose Heavy Duty over Medium Duty Cable Ladder: - Very large or heavy power cable bundles - Long unsupported spans between cable ladder brackets - Mining, petrochemical and power generation environments - Installations subject to mechanical stress or vibration - Any application demanding maximum structural strength and load-bearing capacity Ideal for use in: - Mining and minerals processing plants - Petrochemical and oil & gas installations - Power stations and high-voltage substations - Heavy industrial factories and manufacturing plants - Large infrastructure and civil engineering projects - Any installation requiring maximum cable ladder strength Cable Ladder Range Comparison: - Medium Duty Cable Ladder — 55mm rail height | 100mm–500mm wide - Heavy Duty Cable Ladder — [X]mm rail height | 100mm–500mm wide Cable Ladder vs Cable Tray — Which Do You Need? - Cable Ladder — Open rung design. Best for large power cables requiring maximum ventilation and higher current ratings. - Cable Tray — Solid or slotted bottom. Best for smaller cables and installations requiring full cable support.
