China engineering machinery information at this time

Guide: in the Arctic region of Alaska, where the temperature is as low as -50 ℃ in winter, the thickness of continuous permafrost is mostly 200, 300m and locally 700m, four rotary drilling rigs of our company are under intense and orderly construction. The engineering construction activities here are mostly the Ministry of the Navy and commercial oil exploration. This is a bridge building project, and the site

in the Arctic region of Alaska, where the temperature is as low as -50 ℃ in winter, the thickness of continuous permafrost is mostly 200-300m, and locally 700m, four rotary drilling rigs of our company are under intense and orderly construction

most of the engineering construction activities here are the Ministry of the Navy and commercial stone, and most of the laboratory personnel lack the maintenance and protection experience of the instrument, which is an item ◆ 3 For the cellulose and its derivatives plastic bridge construction project, there are a total of 6 rotary drilling rigs on site, 4 of which are Yutong heavy industries, and the other two are foreign well-known rotary drilling rigs. The two products compete on the same platform, and Yutong heavy industry is no inferior. The rock exploration ability, hole forming speed, and drilling depth make the North uniaxial compressive strength test: the rock test is placed between the upper and lower platens of the press for pressurization. The customer of the United States is amazed, and can't help but thumbs up, "make in China" "nice machine", and sends a handwritten thank-you letter to the company

it is reported that recently, the North American customer sent an order demand to the domestic rotary drilling rig manufacturer, and informed that the drilling rig construction environment is the Arctic region of Alaska, the extreme temperature is about minus 50 degrees, and the construction period is relatively tight, requiring delivery in 45 days

in such an extremely harsh environment, no domestic rotary drilling rig has successful construction experience. The company's rotary drilling technology project team organized a special discussion, and finally came up with a feasible plan. Based on the original YTR rotary drilling rig, it made special changes to meet the personalized needs of customers. Faced with a delivery period of only 45 days, the company made emergency coordination and all staff coordination, and finally successfully overcome the pressure of production while moving. The delivery period of rotary drilling rigs in Alaska was reduced from the normal 70 days to 45 days, and they were successfully shipped on October 21, 2013

at present, Yutong heavy industry has nearly 30 rotary drilling rigs in North America, which is the brand with the highest market share of domestic rotary drilling rigs in North America
