French aerial work platform manufacturer Haulotte posted a 1.5-percent revenue increase in the first half of 2013, with sales of €187.2 million (about U.S. $246.7 million), compared to €184.5 million for the first half of 2012. Operating income increased to €7.2 million, compared to €5.1 million a year ago, a 41.2-percent leap, predominantly because of improved control over fixed costs.Haulotte said the global market for powered access platforms continues to be boosted by growth in the North and South American markets during the first half of 2013, while a “wait and see” attitude continues for European rental companies. Net debt amounted to €51.8 million on June 30, decreasing by half compared to the end of 2012.Despite continuing limited visibility because of persistent macro-economic uncertainties, Haulotte Group expects a second half similar to the first half of 2013, which should allow the company to show growth in sales between 5 and 10 percent compared to 2012.Haulotte Group is based in L’Horme, France, with U.S. headquarters in Archbold, Ohio, and Frederick, Md.
