This machine was originally equipped with a standard excavating robot arm. In order to meet the operational needs of the project, it was customized and modified at our Singapore seller/service provider. Due to the limitations of the container, this machine uses docking processing, and the docking point adopts international standards. Made a replaceable form: 30M: Big arm 16M (docking) + middle arm 2.5M + small arm 11.5M (docking) 24M: Big arm 13M (docking) + middle arm 2.5M + small arm 8.5M

The Nairobi expressway in the capital of Kenya, invested, developed, constructed and operated by China Road and Bridge Engineering Co., Ltd. (hereinafter referred to as China Road and Bridge Corporation), has been in stable operation for the first year, and the cumulative number of vehicles passing through it has exceeded 17 million. The Nairobi Expressway is a fast channel connecting downtown Nairobi and Jomo Kenyatta International Airport. It passes through important landmarks such as the Nairobi Central Business District, the National Museum, the National Stadium, the Parliament Building, and the Presidential Palace. The total length is 27.1 kilometers. Construction will start in September 2020, and it will be officially put into operation on July 31, 2022. It is understood that in the past month, the average daily traffic flow on the Nairobi Expressway has reached 60,000 vehicles. Since the trial operation, the highest single-day traffic flow has exceeded 75,000 vehicles. In addition, the total number of ETC issued exceeded 160,000, and the proportion of ETC users increased from 26.8% at the beginning of operation to 75%. The Nairobi expressway project is deeply involved in Kenya's economic and social development, reducing the travel time from the airport to the urban area from the previous two hours to 20 minutes, significantly reducing logistics and public commuting costs. During the construction period, the project employed more than 6,000 local employees, benefiting 200 local subcontractors and hundreds of local construction material suppliers. In addition, the project employed more than 500 local employees during the operation period, accounting for about 95% of the total number of employees. The Nairobi Expressway Project is one of Kenya's most important infrastructures and a major project to implement the "Belt and Road" initiative. At present, the project has radiated and driven Kenya's transportation industry, tourism and other industries, benefiting millions of Kenyan residents.

In recent years, the mileage of tunnels under construction in China has increased by about 11% annually; about 3,100 new tunnels will be added in 2023; "National Highway Network Planning (2013-2030)" indicates that the total scale of the national highway network planning is 401,000 kilometers; The Outline of Advanced Planning for Railways in a Powerful Country in the New Era states that by 2035, the national railway network will be planned to be 200,000 kilometers, including 70,000 kilometers of high-speed rail... With the continuous increase in the amount of national tunnel engineering, construction machinery equipment used for support operations such as road/railway tunnels, slopes, mine roadways, water conservancy/hydropower tunnels and culverts, subways, etc. Well received by the market. Among them, the sales of Sany wet spraying machine, a "small expert in tunnel concrete spraying", has continued to rise since its launch, which has improved the construction environment of tunnel sprayed concrete, ensured the safety and health of workers, and reduced construction costs. What are the high-quality features of Sany wet spray machine that make it stand out from many brands and win market praise in one fell swoop? Don't blink, next, we will "uncover the secrets" for you one by one. The unique pumping system is more efficient and inherits the industry-leading Sany ace concrete pumping technology, which is highly efficient and energy-saving "not picky eaters" High efficiency: special pumping system for wet spraying machine, the suction efficiency is as high as 95% Energy saving: the industry's first casting energy-saving main valve, lower energy consumption, lower pressure loss Durability: 25% reduction in pressure loss, 10% reduction in commutation impact, longer life and more durability Sany’s special chassis has higher applicability “Equipped with a special engineering chassis, it can adapt to various tunnel construction conditions and complex roads Flexible: four-wheel drive and four-steering, crab driving and two-way driving, the operating platform can be rotated 180 degrees, the turning radius is 5.6 meters, and the maximum climbing gradient can reach 40% Reliable: heavy-duty hydraulic axles, wet brakes, more reliable driving Safety: the design of inclined support legs, the stability of the whole vehicle is better, and the construction is safer Folding telescopic frame more flexible Wide range: 9 degrees of freedom of the boom, the maximum spraying height is 17.5m, the maximum spraying width is 30m, and the 240° spherical spraying has no dead angle High efficiency: the telescopic stroke of the boom and forearm is 2m, the forearm is folded at 240°, the number of moving vehicles is small, and the construction speed is fast Accurate positioning: the forearm is automatically kept horizontal, the nozzle is sprayed vertically on the wall, and the positioning is more accurate Good rigidity: original pentagonal section, stronger and more stable Upgrade the control system to be more intelligent Intelligence: Quick-setting dosage and concrete pumping displacement can be automatically synchronized and matched Worry-free: intelligent self-diagnosis of faults, automatic maintenance prompts, allowing you to use worry-free In the past two years, the country's investment in roads and railways has grown rapidly. The 14th Five-Year Plan pointed out that by 2035, the total mileage of domestic high-speed rail is expected to increase to 240,000 kilometers, and the mileage of expressways is expected to reach 460,000 kilometers. At the same time, Article 6 of the "Nine Regulations on Tunnel Construction Safety" requires in the specific implementation rules that for tunnels with double-line high-risk and above, wet spraying and manipulators must be used for spraying and anchoring operations for step construction projects. Sany Heavy Industry closely follows the pace of national strategy and planning, actively participates in the construction of the national railway and highway network, deploys the manufacturing of wet spraying machine products, and contributes to the development of tunnel wet spraying projects.
