Trailer-mounted mains light tower
A towable tower with a winched mast and no engine, plugged into the site board. Used where the works move but a supply is always within cable reach.
Features
- A winched mast reaches the same heights as a diesel tower without carrying an engine, alternator or tank.
- Because there is no fuel, the unit can be left for the duration of the works with no attendance at all.
- Outriggers and a wind rating still apply — the mast is the same mast, and the lighter chassis makes stabilising more important, not less.
- One distribution board can usually feed several units, but the inrush of all of them closing together is what trips the breaker.
- A plug-and-socket connection means the unit can be isolated and moved by the crew without an electrician.
