Terex has introduced the redesigned RL-4 light tower. Already used in applications such as building and highway construction, oil fields and sporting events, according to the company it features significant improvements.

“Our redesign focused on providing greater efficiency and improved performance for our light tower customers,” said Karen Stash, senior director, global marketing and product management, Terex Aerial Work Platforms (AWP).

“By pairing the vertical mast and larger 45 gallon fuel tank with the ability to get 17 units on a trailer, customers will see the benefits from day one.”

The Terex RL-4 light tower is 23.4 ft (7.13 m) in height with a width of 59 in (150 cm), and a stowed length of 85 in (215 cm).

It has a dry weight of 1461 lbs (663 kg) and has four metal halide 1000 W lamps. High density polyethylene covers eliminate corrosion and dents, and vertical mast with an internal mast brake offers 359ᵒ non-continuous tower rotation and a retractable mast cable.

The company said the light tower’s new vertical mast dramatically cuts set up time by using only one winch for quick operation. Being able to stow the mast on top of the unit instead of hanging over the end reduces the potential that the unit will be damaged in transit.

Its smaller footprint, which allows up to 17 units on a 48 ft trailer instead of 10 with the previous model, also results in significant cost savings.

“We’re able to reduce the footprint thanks to the vertical mast and the added benefit of the foldable tongue,” said Marie Engstrom, associate product manager, Terex AWP.

“This allows the Terex RL-4 light tower to be loaded on a truck sideways, across the truck, instead of down the truck’s length.”

Previously, the Terex RL-4 light tower had a 30-gallon tank and provided approximately 60-hours of run time. The new version has a 45-gallon tank and an efficient engine which extends the run time to as long as 90 hours.

The RL-4 also has an optional autostart feature which uses a photocell or timer to turn on the unit automatically and run when you need it without having to manually start it.

“By increasing the run time by up to 50%, the unit can provide light up to seven nights on one tank of fuel. That’s a tremendous efficiency,” said Ms Engstrom.

The product has a Kohler KDW1003 three-cylinder diesel, liquid-cooled engine with a 6 kW power configuration.

“This engine is considered to be one of the most popular workhorses in the industry and now it’s part of the Terex solution,” added Ms Engstrom.

Kohler has worked to make this engine quieter with less vibration. Terex and Kohler worked together to provide the RL-4 with a larger oil pan so it can go about 500 hours between oil changes.
