To meet its goal, a significant expansion of the North American product portfolio proved to be in order.īeyond its strategic objectives, the expansion will also enable the company to be “a better partner to our dealers,” said Moo Young Park, engineering manager, Doosan Infracore North America. Yet, according to the company, the move is simply the next step in a broader growth plan that includes an annual sales target of $10 billion by 2025. The announcement seemed a significant departure for a division long known primarily for its hydraulic excavators, wheel loaders and articulated dump trucks. Machines are now expected on American soil within weeks, and you’d probably like some details.ĭoosan - Hyundai Doosan Infracore’s (HDI) North American heavy equipment division - previewed a “pre-prototype“ crawler dozer at dealer and trade media events at its proving grounds in Tucson, AZ last December. However, the dozer line that was put in on top of the ridge north of Haystack Mountain during the 2004 fire season and re-opened as a containment line for the Haystack Fire, will remain open as there was already a well-established trail along the fire break prior to the fire, Stevens said.Heads were turned late last year when Doosan Infracore North America announced its entry into the North American dozer market. In the case of the Haystack Fire, land managers don’t want to create any new access routes into the Caribou-Poker Creeks Research Watershed managed by the University of Alaska Fairbanks. dozer lines) that are created during a fire response. Suppression repair on State of Alaska lands typically includes closing off all new access points (i.e. The goal is to return conditions to as close to pre-fire conditions as possible, he said. Land managers pay close attention to the presence and condition of access routes prior to and after a wildfire. While some members of the public view dozer lines as potential new trails that increase access, that’s not necessarily the way land managers see it, Stevens said. Having water controlling infrastructure like water bars in place prior to breakup reduces potential for erosion, he said. Breakup is when there is the highest potential for erosion due to spring snow melt. It is best to have all suppression repair work complete before hard winter sets in so the ground is prepped for spring breakup, said Stevens. Properly installed water bars not only divert water away from unwanted areas, but also slows the water down, lessening the potential for erosion.” “Putting vegetation back in place over cleared ground helps to re-establish the insulating layer. “The main goal of suppression repair is to stabilize disturbed soils as much as possible,” Stevens said. #DOZER LINE SERIES#By constructing a series of water bars at different intervals along a dozer line, the volume of water flowing down the line is reduced, as is the potential for erosion. A water bar is typically a diagonal channel cut across the dozer line that diverts surface runoff as a result of rain or spring snow melt so it doesn’t carve ruts into the soil. Water bars are also constructed to channel water off any cleared lines to prevent erosion, especially on slopes.
