Overview

A light tower is a tall mast fitted with lights, used to light up large areas. Construction sites use these towers, also known as “industrial lighting units”, whenever visibility is low. Mast heights typically range from 20 to 100 feet.

Most light towers are mounted on a mobile trailer or built as a self-contained unit, so they're easy to move from place to place.

We rent two kinds: engine-driven light towers and an electric light tower.

Most of our units are engine-driven, powered by an internal diesel engine that generates electricity for the lights. Diesel towers are usually preferred — they're more durable and use fuel more efficiently than petrol engines.

Troubleshooting

Find a symptom

Engine is running but the lights won't come on

Likely causes

Breakers off
Timer setting
Lamp warm-up / hot restrike
No supply (electric unit)

Checks to try, in order

Switch on the main breaker and each light breaker on the control panel.
Check the timer or auto/manual switch setting.
Metal-halide lamps take several minutes to warm up, and won't restrike right after being switched off hot. Give them 10–15 minutes. LED lamps come on instantly.
Electric tower: confirm the supply cord is connected and the source is live.

Reference draft — always follow the manufacturer’s manual.

Mast won't raise

Checks to try, in order

Lower the outriggers/stabilisers fully. Many towers won't raise the mast until they're down.
Release the mast transport lock or pin.
Manual winch: check the cable is seated on the drum.

Engine shuts down on its own

Checks to try, in order

Check the fuel level.
Check engine oil and coolant with the engine cold. Towers shut down automatically on low oil pressure or high temperature.

If a warning lamp stays on after a restart, don't keep resetting it — call the workshop.

Reference draft — always follow the manufacturer’s manual.

Safety

Look up before raising the mast. Never raise it anywhere near overhead power lines.
Keep the outriggers down the whole time the mast is up.
Refuel with the engine off and lights lowered.
