What Lampson International does

Lampson International LLC is a privately held, third-generation family-owned heavy lift and crane rental company founded in 1946 and headquartered in Kennewick, Washington. The company operates one of the world's largest crawler crane rental fleets — 350+ major pieces of equipment — anchored by its proprietary patented Lampson Transi-Lift® series, which spans lift capacities from 350 to 3,000 US tons. The Transi-Lift configuration uniquely combines the strength of stiff-leg derricks with the mobility of conventional crawler cranes, enabling modular transportability and rapid on-site assembly (LTL-2600 in approximately 6 weeks). Complementing the proprietary fleet, Lampson rents Manitowoc crawler cranes (999, 2250, 16000, 18000, 4100), repowers and refurbishes Manitowoc 4100/4600 cranes under the Lampson Millennium line, and operates crawler transporters exceeding 4,000 tons and rubber-tired transporters up to 3,000 tons. Internal capabilities include in-house engineering, custom rigging and spreader bar fabrication, an 850-ton horizontal hydraulic pull test system at its Pasco facility for rigging certification, steel crane mat rental and sales, marine and barge-mounted crane services, and full-service heavy transport using Goldhofer, Scheuerle, Nicolas, and Cometto trailer modules.

The company serves enterprise customers in energy and power generation (nuclear, fossil fuel, hydro, renewable), oil and gas refining and petrochemicals (Chevron, ConocoPhillips, Suncor, Philips 66, Energy Northwest), mining and minerals processing (Kennecott Utah Copper, Nyrstar Port Pirie), and large-scale civil infrastructure (American Bridge, Kiewit, Bechtel, BNSF Railway). Customer engagements are project-based, contractually negotiated, and execution-led — including refinery turnarounds within constrained shutdown windows, nuclear-grade precision lifts, bridge girder placements, and modular equipment transport in environments ranging from downtown urban cores to remote Australian and Canadian sites. Revenue streams combine crane rental (bare lease and operated), heavy lift project services, heavy transportation, custom fabrication and manufacturing (including third-party pull testing), Millennium crane sales, and steel mat rental/sales. Pricing is quote-based; no standard price list is publicly disclosed.

Lampson operates through wholly-owned Lampson Canada LTD (Beiseker, Alberta) and Lampson Australia PTY LTD (Toronto West, New South Wales), with US offices in Kennewick (HQ), Pasco (engineering and manufacturing), Commerce City/Denver, Liverpool/Houston, Laveen/Phoenix, and Seattle. The company has operated in more than 55 countries across 80+ years and holds a 30-year strategic partnership with Hitachi Ltd., with whom it co-developed the LTL-3000 crane for Japan's nuclear reconstruction market. Distribution is exclusively direct enterprise field sales, with no dealer, marketplace, or e-commerce channels.

Partnerships

One partnership is on record.

• Hitachi, Ltd.flagshipStrategic or Co-development Partner · 1 January 1994Lampson's closest international partner, with a 30-year strategic relationship. Lampson and Hitachi co-developed the LTL-3000 (3,000 ton capacity) specifically for Hitachi's Japanese operations. Hitachi is a Japanese multinational conglomerate operating in eleven business segments including Construction Machinery. The LTL-3000 crane is intended for use in Japan's recovering nuclear sector, with reconstruction taking 8-10 weeks on-site in Japan. This co-development relationship has produced Lampson's flagship crane model and validates the Transi-Lift technology in one of the world's most demanding engineering markets.
