PASCO, WA - You may have noticed the bright orange and white crane towering above the railroad yard in Pasco. It's actually the world's largest twin crawler mobile crane being built in the Tri-Cities by Lampson International LLC.
The Transi-Lift LTL-3000 is 400 feet tall and a little more than 200 feet wide; it can lift around 3000 metric tons. It was originally built for Hitachi, a Japanese engineering and electronics company in Japan, to help build power plants. However, the country's nuclear program is currently under suspension.
Lampson representatives say building the mammoth machine was challenging and rewarding, at the same time. "We took a big step from our smaller machines and did an all-new hydraulic hoisting system...all-new electronics and computer controls," said Randy Stemp, the engineering projects manager at Lampson International.
"Even though we are a small company right here in the Tri-Cities in Eastern Washington, we are helping other countries around the world. I think that says a lot about manufacturing in Washington state," added Kate Lampson, the director of public relations at the company. “All Transi-lift models boast precise maneuverability, adjustable stinger length, and multiple boom/jib combinations allowing us to work in smaller footprints and challenging spaces,” Lampson says. “In addition, our new LTL-3000 model has new joystick controls in our operator’s cab, hydraulic hoisting capabilities, a newly designed enclosed engine compartment, a 3,000 ton front crawler giving us 33 percent larger crawler capacity, a larger boom section at 16 by 20 feet and an increase from 1.5 inch diameter wire rope to 2-inch wire rope.”
It took about two years to build the Transi-Lift LTL-3000. Lampson says the machine will stay in the Tri-Cities until Hitachi finalizes its plans.
