New Light Tower Combines Nimble Size and High Power

Doosan Infracore Portable Power's new LSC has compact design with premium features Doosan Infracore Portable Power recently introduced its Ingersoll Rand LSC (LightSource Compact) portable light tower, designed for rental/construction markets. The new model features a compact platform that provides a smaller on-site footprint than its full-size counterparts, yet provides equivalent wind-resistance, static-roll threshold and extension heights. Important for rental dealers, the LSC is designed to allow 11 fully assembled units to be transported on a single, 48-foot flatbed trailer.

Equipped with a 4.5-kW generator powered via a water-cooled Mitsubishi L3E diesel engine (Tier-4-Final compliant), the LSC uses four 1,000-watt metal-halide floodlights, each having a side-mounted, horizontally positioned bulb in a rectangular fixture and providing a light distribution of 460 foot-candles. The cast-aluminum fixtures incorporate separate anodized aluminum reflectors that reduce the possibility of losing the bulb if the outside casting is damaged.

The fully galvanized, telescopic steel tower extends from 12 to 30 feet and can be rotated 360 degrees and locked in place for precise aiming. The tower is raised via dual, hand-operated winches that incorporate automatic safety brakes. The curled-type cord to the floodlights is contained within a protective steel shroud along the first section of the tower to prevent damage from pinching or puncturing. When in a horizontal position during transport and storage, the LSC's tower is automatically locked in place.

A four-point outrigger and jack system provides 65-mph wind resistance for the 1,650-pound LSC. When fully deployed, the stabilizing system requires only 129 inches side-to-side and 107 inches front-to-back. In the transport mode, the LSC measures 166 inches in length and 53 inches in width.

The new LSC uses a seven-gauge-steel frame with an integral tow bar. The robust frame, says Doosan, provides strength and stability during transport and light-tower operation. Trailer features include a full DOT running-light package, 2-inch ball hitch and 13-inch tires. All critical wiring is extended to the drawbar to facilitate hook-up to the tow vehicle. The trailer also is fitted with four tie-downs, zinc-plated chains, license plate holder and VIN number. Polyethylene fenders minimize the prospect of damage, and "galvannealed" sheet metal with undercoating provides rust and corrosion protection.

Added protection for the LSC includes automatic shut-down systems for high engine-coolant temperature and low engine-oil pressure. Also available is a low-fuel shut-down system. Options include dual electric winches with automatic safety stops, hitch configurations and engine-block heater. The LSC carries a two-year/2,000-hour bumper-to-bumper warranty.
