The LM-50-5S-TLR-16X400LTL-LED from Larson Electronics is a trailer mounted fold over seven stage light mast that provides a safe and effective way for operators to quickly deploy sixteen 400 watt LED light heads to elevations up to fifty feet. This pneumatic light tower folds over for easy transportation, features a hydraulic ram upright assist, an air powered pneumatic mast and high output LED light fixtures. The entire assembly is mounted on a 21’ by 8’ tandem axle trailer that allows operators to transport this boom from one location to another. The tower is constructed of heat treated aluminum tubing with 2.69’ of overlap per section. This light boom can be extended to 58’ for maximum area coverage, and collapsed to 22’ for applications where a footprint smaller is required. The mast is elevated using an included hydraulic ram and is extended to its full height using a trailer mounted air compressor. The elevation is controlled by a push button switch to operate the hydraulic ram, allowing operators to raise the mast to the upright position. The vertical deployment is operated by an up/down level, allowing operators to extend it to its full 50’ height or retract it to the collapsed height.
The sixteen light heads included with this tower are our wet area suitable GAU-LTL-400W-LED high output LED fixtures that produce 52,000 lumens of light at 400 watts each. Each light head contains fifty-four Bridgelux high output LEDs producing 963 lumens each arranged in rows and paired with high purity optics to produce a well-focused 25° wide spot beam that is ideal for providing far reaching concentrated illumination while still covering a substantial amount of area. Each light is securely fastened to the light boom and each lamp includes a support bracket to help maintain lamp stability within its housing. The lamps are hard wired into a NEMA 3R panel located on the end of the telescoping boom. Power is provided to the control box via a 20’ 10/4 SOOW whip with flying leads for connection to terminal mount gensets.
The entire unit is mounted onto a four wheel, tandem axle trailer constructed of eight inch box steel equipped with axles. Each axle is rated at 7,000 pounds and equipped with P235/80R16 tubeless tires and wheels. The rear axle is equipped with electric brakes. Tongue weight is rated at 650 pounds and an adjustable 3” lunnett eye for pintle hitches provides secure hookup to tow vehicles. A single 7,000 pound rated tongue jack provides a stable connect-disconnect platform as well as additional stability during tower deployment. The trailer is finished in Dupont paint for protection against rust and corrosion and provides an attractive finish.
“Our new 50’ pneumatic light mast is by far the brightest and biggest light mast we have ever manufactured,” said Rob Bresnahan with Larsonelectronics.com. “It is designed to provide operators with a heavy duty, stable, reliable unit that produces extreme light output no other tower can compare to.”
