Overview

Moxy Engineering was a Norwegian heavy-equipment manufacturer specializing in articulated haulers, also known as articulated dump trucks, for off-road earthmoving, quarrying and construction work. The company was founded by Norwegian industrialist Birger Hatlebakk, who had earlier established the Glamox factory in Molde Municipality. Moxy’s identity was built around vehicles capable of carrying heavy loads across uneven terrain, with engineering emphasis on traction, stability and drivetrain performance rather than conventional road transport. The company produced its first dump-truck prototype in 1970. One early design used a powerful tractor as the basis for a heavy-duty truck, with rear-wheel drive provided through hydraulic motors. A second prototype, also completed in 1970, was an articulated dump truck powered by a Scania diesel engine. The initial prototypes were built in Molde Municipality before production activity moved to a new factory at Varhol near Elnesvågen in Fræna Municipality. Moxy also acquired Øveraasen Motorfabrikk & Mekaniske Verksted in Gjøvik, obtaining additional engineering and manufacturing capabilities. Moxy introduced its first commercial articulated dump truck, the Viking D15, in 1972. The model used a bogie beneath the dump box and six-wheel drive, features suited to demanding off-road conditions. The trucks received a positive response in the earthmoving industry, and during the 1980s the company developed additional models and expanded exports to several countries. To increase production capacity, Moxy worked with Tallmek Smøla AS, which manufactured dump bodies. The company also entered a cooperation agreement with Japan’s Komatsu; during part of this relationship, Moxy-built dump trucks were sold by Komatsu under the Komatsu brand. Ownership and distribution changed repeatedly. Around 1980, English company Brown Engineering acquired Moxy and renamed the business Moxy Industries AS. In 1991, the Norwegian state-owned company AS Olivin and Komatsu jointly acquired the manufacturer, with Olivin holding two-thirds and Komatsu one-third of the shares. The owners supplied new capital, while access to Komatsu’s sales network contributed to a substantial increase in sales. When Komatsu withdrew from the partnership in 2000, Moxy lost important distribution outlets and sales declined. The resulting contraction led to workforce reductions and occurred alongside the Norwegian state’s partial privatization efforts involving Olivin. As part of the restructuring of Olivin, the state injected 50 million Norwegian kroner into the company and separated the struggling Moxy operation as a state-owned company. In 2002, 51 percent of Moxy was sold to Spilka Invest AS of Ålesund Municipality. Demand subsequently improved as the Norwegian economy strengthened. The company’s assets were later acquired by the English Thomson group, with production continuing under the new corporate name Moxy Engineering AS. In 2008, Doosan Infracore’s Construction Equipment Business Group acquired all of Moxy Engineering from Thomson Group and renamed the company Doosan Moxy AS. In 2011, the Moxy name was discontinued in product marketing, and later articulated dump trucks were sold solely under the Doosan brand. Moxy therefore survives primarily as a historical marque and engineering lineage within the development of Doosan’s articulated-hauler business rather than as an independent active brand.

History

Moxy Engineering emerged from Norway’s industrial manufacturing sector under the leadership of Birger Hatlebakk, an industrialist also associated with the founding of Glamox. Its initial focus was the development of dump trucks able to operate away from paved roads and in the difficult ground conditions common to construction, quarrying and earthmoving sites. The first prototypes were completed in 1970. One design combined a heavy-duty dump body with a powerful tractor and hydraulic-motor drive to the rear wheels. Another prototype, also completed that year, adopted an articulated configuration and a Scania diesel engine. After the earliest work in Molde Municipality, Moxy moved production to a new factory at Varhol near Elnesvågen in Fræna Municipality. The acquisition of Øveraasen Motorfabrikk & Mekaniske Verksted in Gjøvik expanded the company’s engineering base. The first marketed articulated hauler was the Viking D15, introduced in 1972. Its six-wheel-drive system and bogie arrangement under the dump box reflected Moxy’s focus on traction and load stability in rough terrain. The product gained acceptance among earthmoving customers. Throughout the 1980s, Moxy introduced further dump-truck designs, built an export business and developed manufacturing relationships to increase capacity. Tallmek Smøla AS produced dump bodies for the company, while a cooperation agreement with Komatsu created an important route to international distribution. Some Moxy vehicles were sold by Komatsu under the Japanese company’s own brand. Ownership became more complex during the company’s later history. Around 1980, Brown Engineering of England acquired Moxy and changed its name to Moxy Industries AS. In 1991, AS Olivin and Komatsu acquired the company together. Olivin held two-thirds of the shares and Komatsu one-third. The new ownership provided additional capital and connected Moxy products to Komatsu’s sales network, producing a marked increase in sales. The partnership weakened when Komatsu withdrew in 2000. The loss of Komatsu outlets reduced Moxy’s market access, and falling sales led to reductions in the workforce. These developments coincided with the Norwegian state’s attempt to partially privatize AS Olivin. To make Olivin more attractive to prospective buyers, the state injected 50 million Norwegian kroner and separated the underperforming Moxy business as a state-owned company. In 2002, Spilka Invest AS, based in Ålesund Municipality, acquired 51 percent of Moxy. Economic conditions then improved and demand for the company’s dump trucks recovered. The business later passed to the English Thomson group, which acquired its assets. Production continued under the Moxy Engineering AS name. In 2008, Doosan Infracore’s Construction Equipment Business Group bought the entire company from Thomson Group and renamed it Doosan Moxy AS. Doosan subsequently consolidated the brand architecture: from 2011, new trucks were marketed under the Doosan name without the Moxy designation. This ended Moxy’s life as an independently marketed equipment brand, although its products and engineering heritage formed part of the history of Doosan’s articulated dump-truck operations.
