Price of 6-8 person emergency rescue hovercraft
$1
Category: Chemicals/Chemical Intermediates/Intermediate Compounds
Company: Hebei Dongsheng Safety Protection Equipment Co., Ltd.
Product Description: Advantages of Hebei Five-Star Power Equipment Co., Ltd.'s "Tyrannosaurus" Hovercraft (Amphibious Hovercraft) and Flood Emergency Rescue Hovercraft in Disaster Relief Operations1. The "Tyrannosaurus" hovercraft (amphibious hovercraft) and flood emergency rescue hovercraft can conduct timely and rapid flood inspections: Floods typically occur across vast areas, often accompanied by severe weather such as strong winds and heavy rain, with rapid water flow leading to transportation blockages and communication interruptions. Therefore, timely and rapid flood inspection is a top priority. Under adverse conditions, conventional vehicles and boats cannot operate. However, hovercraft are not restricted by terrain; they can hover over water surfaces, ground, shallow waters, and marshes, with speeds generally ranging from 60 to 100 km/h. This allows for timely, rapid, and comprehensive flood assessment, facilitating the implementation of disaster relief efforts.2. Hebei Five-Star Power Equipment Co., Ltd.'s "Tyrannosaurus" hovercraft (amphibious hovercraft) and flood emergency rescue hovercraft have greater advantages over conventional assault boats and rubber dinghies in flood control, emergency response, and disaster relief:Although conventional assault boats and rubber dinghies can transport supplies and personnel during disaster relief, playing a significant role, they cannot navigate when water currents are rapid, river conditions are unclear, or when floods and heavy rain submerge streets and alleys. They are also unable to operate in non-navigable waterways. While small vessels like rubber dinghies and assault boats can approach targets and serve a purpose in rescue operations, they are highly unsafe in rapids, cannot move against the current, and cannot perform rescues in streets and alleys. In contrast, the "Tyrannosaurus" hovercraft (amphibious hovercraft) and flood emergency rescue hovercraft, with their elevated hulls, can "fly" over any complex terrain, water surfaces, streets, and alleys. Additionally, these hovercraft have immense buoyancy, ensuring they never capsize, thereby guaranteeing the safety of both rescuers and those being rescued.3. The "Tyrannosaurus" hovercraft (amphibious hovercraft) and flood emergency rescue hovercraft can access areas unreachable by vehicles, boats, or helicopters to carry out rescue operations.After a disaster, using the "Tyrannosaurus" hovercraft (amphibious hovercraft) and flood emergency rescue hovercraft to perform rapid and safe search and rescue missions is the only effective solution. These hovercraft safely hover 0.25 to 2 meters above water or ground surfaces, enabling rescuers to reach areas, streets, communities, and alleys inaccessible to vehicles, boats, or helicopters under extremely adverse conditions. They can clear obstacles and carry out disaster relief and evacuation efforts at the fastest possible speed. Equipped with rescue platforms and handrails, rescuers on board can quickly approach and safely rescue individuals or objects.4. During urban waterlogging, the "Tyrannosaurus" hovercraft (amphibious hovercraft) and flood emergency rescue hovercraft can navigate submerged streets to conduct disaster relief operations.When floods occur suddenly, with rivers breaching dams and residential areas, it is nearly impossible for assault boats or rubber dinghies to navigate submerged streets (due to underwater obstacles such as walls, fallen trees, submerged vehicles, etc.), as this could damage the vessels' propellers. Hovercraft, however, are entirely unaffected by underwater obstacles and can reach the scene at the fastest speed to rescue people and transport supplies.5. The "Tyrannosaurus" hovercraft (amphibious hovercraft) and flood emergency rescue hovercraft can serve as mobile medical clinics in disaster areas.In some of the most remote and inaccessible disaster areas, hovercraft can provide clean, safe, and spacious cabins equipped with complete medical facilities to meet medical needs, forming ideal mobile medical clinics.Capable of "Flying" on Land and Water, Navigating All Terrains and WatersThe WX-8 emergency rescue hovercraft is a professional amphibious hovercraft in China's emergency rescue industry. It is capable of operating efficiently and机动ly in various complex terrains, including water surfaces, flood rapids, urban waterlogging, ice surfaces, mudflats, beaches, marshes, and land. It is designed to quickly respond to emergency rescue, flood control, water rescue, and complex geographical environment救援 needs, enabling the timely rescue of trapped individuals and the rapid transport of disaster relief equipment, supplies, and personnel under恶劣 conditions.Multifunctional and VersatileWidely applicable in: flood control and prevention, earthquake and mudslide disaster relief, emergency rescue,野外 emergency support, water and ice rescue, urban waterlogging, patrol, hydrological survey, fishery law enforcement, and other fields.Long EnduranceThe total fuel tank capacity of this model is 120L, with a main tank of 80L and an auxiliary tank of 40L, ensuring an endurance of no less than 3 hours.Stable and Reliable Operation in恶劣 WeatherEquipped with an advanced mechanical control system, forced circulation water cooling system, and engine preheating system, ensuring stable and reliable engine operation under various adverse weather conditions.Excellent Buoyancy PerformanceEven when the engine is stopped, it can remain stable on water surfaces or mudflats without sinking, ensuring navigation safety.Segmented Skirt DesignFeatures a segmented skirt design using PVC mesh fabric and TPU bonding materials. This not only enhances the hovercraft's adaptability and durability but also ensures stable operation across a wide temperature range from -40°C to 40°C.Customizable EquipmentCan be equipped with emergency modules and rescue器材 as neededCan carry emergency equipment modules and rescue devices, including:Emergency drainage pump stations, generator sets, communication and command systems,野外 water purification devices, remote-controlled unmanned life-saving robots, water rescue floating boards, long-range multifunctional life-saving pole combinations, searchlights, fog lights, side lights, warning lights, loudspeakers, and basic rescue and life-saving equipment to meet passenger capacity requirements.Amphibious Capability to Conquer All TerrainsApplications:Flood control and prevention, emergency rescue, power emergency repair, firefighting, urban waterlogging, municipal drainage, geological survey, disaster protection, earthquake rescue, medical assistance, hydrological detection, public security pipeline inspection, forest security, fire investigation, snowfield support, grassland fire prevention. more>

Storage and Transportation Conditions: Store and transport in a moisture-proof environment, maximum stacking height of 5 layers11. Shelf Life: 4 years【【3】】Water-blocking Expansion Bags, Flood Control Water-absorbing Expansion Bag Applications:(1) Preventing embankment landslides: When an embankment experiences landslides due to seepage, failure to address it promptly may lead to a breach. Specific usage method: Stack water-absorbing expansion bags in multiple layers in a "pin" shape at the lower part of the landslide to quickly halt further soil movement, allowing time to fill and repair the damaged embankment.(2) Raising embankments: Based on flood forecasts, if water levels are expected to exceed design flood levels or even the embankment itself, use water-absorbing expansion bags to construct a temporary levee on the water-facing side of the embankment before the flood arrives to prevent overflow. Specific usage method: After the water-absorbing expansion bags have expanded, layer and compact them in a staggered manner. To prevent interlayer leakage, add loose soil between layers. Combining with plastic film enhances anti-seepage effects.(3) Wave dissipation and erosion prevention: During rapid flooding and rising water levels, which exert immense pressure on flood control embankments, the flexibility of water-absorbing expansion bags allows them to be securely stacked along the embankment to buffer the impact of floods, thereby protecting the embankment. Specific usage method: Lay the water-absorbing expansion bags flat, tie both ends to stakes on the embankment, and place them directly on the water surface. Once expanded, the bags' buoyancy enables them to float with the waves, dissipating wave energy.【【4】】Water-blocking Expansion Bags, Flood Control Water-absorbing Expansion Bag Usage Instructions:1. When not in use, store the flood control expansion bags in a dry indoor area for standby use. They can be deployed during flood seasons or typhoon/rainy seasons for water absorption and flood control.2. During use, open the water-absorbing expansion bag package, immerse the bag in nearby water or directly pour water over it for flood control. After about 3-5 minutes, the bag will expand 80–100 times (approximately 15kg), and then move it to the required location for flood blocking.3. After the flood recedes, unused bags can be resealed and stored in a dry indoor area. Used bags should be air-dried naturally and disposed of as waste—non-toxic, harmless, and pollution-free.★ Precautions:1. Secure both sides of each layer of water-absorbing expansion bags firmly to the embankment.2. Connect water-absorbing expansion bags using iron wires or hemp ropes.3. Before use, seal the water-absorbing expansion bags in plastic packaging; avoid any damage.Hebei Wuxing Power Equipment Co., Ltd. is growing! Marching forward with solid steps!
