Product Description
- Brief introduction of big board shelter:
1. Wide applications: The shelters can be used as movable command post, communication control center, radar station, aviation control tower, TV & Broadcasting transmitting station, machine & electron repair place, field hospital, exploration & surveying station, field kitchen, electricity stage and so on.
2. Good maneuverability and flexible transport manners: The shelters can be transported by sea, land (railway & highway), air (cargo airplane & helicopter). Through adopting matching vehicles or trailers or installing stepping wheels or motion wheels or goods shelves or slide sledges, the shelters can step or be transported for a certain distance, which is convenient for evacuating, hiding and motion so that the users can choose advantaged ground and position to cover the shelters so as to improve survival capability and ensure command, communication and control not to be broken off.
3. Various defending capability: The shelters have comprehensive defending capability. According to customer’s request, we can make different choices and designs on the materials and structures of the shelters. The finished shelters have good properties of airproof (water and air), isolation (including electromagnetism screen, heat isolation and preservation, rush and shake isolation) so as to fit all kinds of weather and sea salt fog environment. The shelters have the capability of fireproofing, anti-infrared ray and anticorrosive.
4. Improving the working environment, ensuring the working continuity and dependability: Besides the installation of working facilities and related matching accessories, the shelters have other matching equipments, such as air-condition, electrical source, lighting, security and alarm, so the shelters can keep good inner environment so as to ensure the continuity and reliability of communication, command, campaign, logistics safeguard under adverse circumstances.
5. Easy seriation, standardization and generalization with a long shelf life: According to different applications, we can design different types and different series shelters, which is convenient for industrial production and maintenance. We can also design, develop and manufacture other series big board shelters.
