Rotary drilling rig is suitable for construction machinery into the hole in the foundation engineering construction jobs . Primarily for soil construction sand, clay , silt , etc., in the pile , continuous wall , a variety of foundation construction foundation reinforcement are widely used , rotary drilling rig rated power is generally 125 ~ 450kW, power output torque is 120 ~ 400kN · m, maximum pore diameter of up to 1.5 ~ 4m, maximum pore depth of 60 ~ 90m, to meet the requirements of various large-scale infrastructure construction .
Rotary drilling rig driven by Qinghai-Tibet Railway Engineering industry due to the Beijing Olympics and the 2003 projects , market awareness is rapidly increasing, the rapid expansion of market capacity. Rising market demand attracted to enter the domestic large-scale engineering machinery enterprises , Sany , XCMG, Zoomlion and Sunward have been involved , and the rapid expansion of the market share. After 2005 , the domestic brands of rotary drilling rig has basically replaced the foreign brands. Since 2006, Rotary Drilling was leaps and bounds in recent years sales growth . Especially in 2009 , the domestic manufacturers of rotary drilling rig up to 30 , launched nearly 200 types of products, market holdings to nearly 4,000 units , an unprecedented fierce competition in the market .
The first half of 2012 , there have been fleeting railway construction period of stagnation , the second half , railway construction to get strong support of national policy, substantial growth investment. 2012 can be said to be a "blowout" of subway construction in China . Last November 26 , Beijing , Nanchang , Fuzhou and Urumqi four urban rail transit construction plan is approved, a total investment of 134.69 billion yuan . On September 5 this two months ago , 18 cities, 25 urban rail project plan approved investment over 800 billion yuan . By this calculation, the total investment scale urban rail approved in the year 2012 nearly 1 trillion yuan . These projects will be pulling the rotary drilling rig products sales strong support.
It is a collection of online center will have 245 models of rotary drilling rig products, brands reached 36 , respectively, Liebherr, XCMG , Sany , Zoomlion , Fukuda Revo , Sunward , Hill pushed , Terex Adams , Kato , Yuchai, peak Heavenly , Yutong Heavy Industries, radius , Liugong , constant day 1995 and Bauer , Hongda , Shandong YUANYOU , Kim machinery, move mountains, AOSHENG special, Binzhou rig, Kawashima , Star of the East , Sanli , Wei Shinuo , Bo , high strength , vibration , and heavy machine Xin country , CRCC , Debon , China South Locomotive , Shaanxi construction Machinery , Kun -yu heavy Industries .
Reporter believes that with the advance of urbanization , continuous release of 40 trillion investment in infrastructure , real estate investment rebounded and government infrastructure construction in the western region of acceleration, including transportation , water conservancy , urban construction, resources development , including development projects in full swing , providing a favorable market environment for foundation engineering machinery sales .
International market, since 2005 thirty-one achieve export since rotary drilling rig to Sunward, XCMG , Sany , Yutong Heavy Industries and companies are represented Jintai increased export sales efforts , at present, the BRIC countries , Southeast Asia and Africa and other regions of increased demand , the export market will also become another major source of rotary drilling rig corporate profits.
In the rapidly growing market holdings , the construction unit continued to reduce adverse circumstances , our rotary drilling rig manufacturers how to improve customer purchase intention , grasp quality customers , reduce customer risk overdue , a problem corporate priority.
