More light from magnum: new light towers, generators continue company's growth

Continuing the expansion of its range of mobile light towers, Magnum Products LLC has introduced a new top end to its Nightbuster light tower line. The MLT5200 light tower is available with four or six of Magnum's newly designed lights that can illuminate as much as seven acres, and the unit can also provide up to 20 kW of electrical power to run tools or other worksite accessories.

According to Magnum President and Co-owner Steve Romme, the MLT5200 was originally designed to the specifications of a specific customer, but the company later decided to develop it as a standard offering. "Again, it all comes back to listening to the customer and providing what they need," Romme said. "It's what we're good at."

The MLT5200 light tower is powered by a four-cylinder, liquid-cooled Isuzu 4LE1 diesel engine rated 31 hp at 1800 rpm, which drives a Marathon brushless, self-regulated generator. The other models in the MLT range incorporate Marathon generator ends driven by Mitsubishi liquid-cooled diesels, with Radiator Specialists cooling systems.

The MLT5200 light tower also offers 20 kW of prime power at 120/240 Vac with [+ or -] 1% electronic voltage regulation. Six external outlets are provided--two 120 Vac 20 amp GFCI duplex outlets, two 240 Vac 30 amp twist-lock outlets and two 125/250 Vac 50 amp three-pole, four-wire twist-lock outlets.

Like the company's other light tower models, the MLT 5200 is offered with options of four or six of Magnum's new brighter lights with dual manual or electric mast winch systems. The mast can be extended as high as 30 ft. and with the outriggers in place, the unit can withstand winds as strong as 65 mph, the company said.

The MLT5200 enclosure offers a lockable storage area for the lights as well as an integral containment system in case of fuel or coolant spills. The unit has a 57 gal. poly fuel tank that provides a run time of 27 hours at full load.

Magnum has also made recent modifications to its Magnum Mobile Generator (MMG) line. After incorporating Tier 2 diesel engines and making some other modifications, many of the products have changed model number and performance specifications.

The MMG line uses all liquid-cooled John Deere Tier 2 diesel engines rated 43 to 512 hp at 1800 rpm.

The company has discontinued production of the smallest model, the MMG 25, for the rental markets. According to Magnum Marketing Manager Jim Roberts, with the switch to the new engines the company found that it could provide the more powerful MMG 35 for almost the same cost as the MMG 25. "It wasn't a difficult decision," he said.

The MMG 35 incorporates a liquid-cooled, turbocharged John Deere diesel engine rated 43 hp at 1800 rpm that drives a Marathon brushless generator. The engine and generator are packaged in a smaller housing than the MMG 25, yet has a three-phase output of 29 kW standby (26 kW single-phase standby).

Magnum has also recently unveiled a new range of mobile generators. According to Romme, the Magnum Light Generator, which was released in the first quarter, "was born out of listening to the customer.

"Our customers wanted a lower-cost model, especially when they didn't need all of the features that our MMG line provides," said Romme. "So we looked where we could cut cost."

One of the cost-saving measures was to package the new generators into the same enclosures used in Magnum's light towers. This helped "lower the cost of acquisition by 25 to 30%," Roberts said.

The MLG 8 and MLG 15 are driven by liquid-cooled, naturally aspirated Mitsubishi engines, rated 10.4 and 22 hp at 1800 rpm, respectively The MLG 20 and MLG 25 generators are driven by 2.2 L, four-cylinder, naturally aspirated and liquid-cooled Isuzu diesels rated 31 hp at 1800 rpm. The smallest model is cooled with a Radiator Specialists system and all others with Diesel Radiator and Copar systems.

The units have runs times of 60 and 48 hours on the respective MLG 8 and MLG 15 units and approximately 27 hours on the MLG 20 and MLG 25 models.

The MLG traits are all equipped with low oil/high temperature shutdown systems, a start limit main breaker that prevents the unit from being started under load and an external emergency stop switch. The company sources the control panels for its MLG and MLT machines from Riverland Laser, River Falls, Wis.

The MLG 8, 15 and 20 have single-phase outputs of 8, 15 and 20 kW respectively at 120/240 V. The MLG 25 provides 20 kW (25 kVa) three-phase and 16 kW single-phase. A selector switch on the MLG 25 allows the operator to choose between voltages of 120, 139, 208, 220, 240 and 277 V single-phase and 208, 220, 440 and 480 V three-phase.

All of Magnum's MLG models utilize Marathon brushless alternators. They incorporate external outlets with individual breakers including two 120 Vac 20 amp duplex outlets, three 240 Vac 30 amp twist-lock and one 240 Vac 50 amp twist lock outlets, as well as a grounding lug.
