The spatial structure of the high-tech industrial zone in Shenyang is a ring, a gallery, and three pieces. The first ring is the tricyclic industrial belt, which is composed of electronic information in the Weinan New Area surrounding the core area of ​​the Third Ring Road and advanced equipment manufacturing in the Tiexi District. The gallery is a group of Xihe Fine Chemicals in the Shenxi Industrial Corridor. The three pieces are relatively independent Hutai Group, Xinmin Group, and Xinchengzi Group.
The development of the industrial belt takes the Gaonan High-tech Zone as the leader, along the line of the Third Ring Road as the main body, and focuses on the high-tech industrial core bases along the South Third Ring Road, the northern Puhe New City group and the western Zhangshi Group.
The industry focuses on the development of eight high-tech industries, including advanced equipment manufacturing, energy conservation and environmental protection, chemical and new materials, biotechnology and pharmaceuticals, electronic information, automobiles and parts, civil aviation, and modern agriculture. It will focus on building high-end CNC machine tools and control systems. , IC equipment, automatic identification technology, civil aircraft and parts and components, and a number of important national high-tech industrial bases.
In order to ensure the construction of high-tech industry belts, Shenyang will take a high starting point and a high level to grasp the preparation of industrial belt plans, and further clarify the objectives, spatial layout, industrial positioning, land use, and infrastructure construction of industrial development. Establish and improve the target responsibility system and assessment system for the development of high-tech industries. Promote the introduction and development of high-tech industries with major projects, carefully nurture and introduce a number of high-tech projects that attract major forces; introduce well-known strategic investors at home and abroad; support competitive high-tech enterprises to go global, and merge advanced foreign technologies Enterprises, master the core technology; create a good policy, living environment, the introduction of overseas high-end talent to participate in major science and technology projects.
In order to accelerate the development of the high-tech industry belt, the municipal government will give policy support to high-tech enterprises. In addition to setting up a 50 million yuan annual special fund to accelerate the development of high-tech industries, Shenyang City will also set up high-tech companies to reach the guidance period. For Shenyang's science and technology enterprises that have yet to meet the national high-tech enterprise certification standards, they may be included in the mentoring period.
Mini Excavator ,Crawler excavators are relatively widely used, characterized by large traction force, low ground contact pressure (generally 0.04-0.15Mpa), good stability, and good off-road performance and climbing performance. It is widely used in occasions with poor working conditions, according to the general rental standard crawler excavator on the ground; if the load capacity of the ground is strong and the ground is uneven, the narrow track type excavator should be leased; if When the load capacity of the ground station in the working condition is poor and the soil is loose, the excavator with extended crawler track and widened crawler pads should be rented; if it is constructed in a swamp, a dedicated crawler excavator for swamp should be rented. Note, however, that the longer the track, the wider the track shoe is, the better. Storage shelves, FAG bearings, Swedish SKF bearings, NSK bearings, Tianjin reducers, linear guide track shoes that are too long and wide will wear faster, and the support wheels, guide wheels and drive wheels will also be subjected to frequent external force impacts too early Damage; Similarly, machines with too short tracks and narrow track shoes that work under unsuitable conditions can also cause premature damage. Excavators with different walking methods have different operation skills.
