hether it’s at a construction site, a mining operation or some other outdoor location, light towers are ever-present for those projects that require work to proceed day and night. Keeping those light towers operational through the night isn’t just essential to job completion, it’s imperative for providing safe working conditions.

Offering a safe and easy-to-use line of trailer-mounted light towers, Terex provides the tools to help get the job done on time and on budget. These heavy-duty models also include a variety of features and options to help maximize the productivity of each unit for specific jobsite needs.

One such cost-effective method of increasing jobsite productivity is to provide the light towers with an automatic lighting management system, which provides automatic on/off light control by photocell, timer or both. Allowing the light towers to start up and shut down automatically results in fewer personnel hours spent manually starting and stopping the units, as well as potential fuel savings from not running the machines during daylight hours.

According to David Spears, product manager for Terex light towers, the potential for increased jobsite productivity is fairly obvious. “Especially in applications where there is a large fleet of light towers or where they are located in remote locations, turning lights on and off every day can occupy a lot of time and manpower.”

DynaGen Technologies supplies Terex with the engine control module that allows for the automated start/stop features. The light management system is available on the Terex AL4000, AL5000 and AL8000HT light towers.

DynaGen’s ES52LT AutoStart engine controller is designed for harsh environmental conditions – delivering resistance to shock, temperature extremes, moisture and electrical interference – the types of conditions into which these light towers are often placed. The ES52LT has been sold as an option on Terex light towers for over four years, often into cold, harsh, off-road environments like mines and construction sites.

The ES52LT control unit offers several features that are engineered to allow for easy installation and easy service, if needed. Its production-line friendly design includes plug-in terminals, high capacity removable relays, built-in kickback diodes, a pre-installed removable fuse and the capacity for direct generator connection. It also offers fully field adjustable settings.

Another useful feature of the light management system is the ability to preset a light tower’s start up or shut down with a programmable timer. That is, the tower might start up automatically with diminishing ambient light, but an operator may wish for the lights to shut down before daybreak. DynaGen also supplies the timer to Terex.

Regardless the application, Terex light towers offer maximum flexibility and productivity for controlling unit operations.
