Sany high-prototype wet spraying machine, the best choice for the Sichuan-Tibet line!

The 14th Five-Year Plan states that by 2035, high-speed railways will increase from 40,000 kilometers to 240,000 kilometers, and high-speed railways from 150,000 kilometers to 460,000 kilometers. At the same time, the specific implementation rules of Article 6 of the "Nine Provisions on Tunnel Construction Safety" require that high-risk and above railway double-track tunnels must be sprayed with wet spray and manipulators for step construction projects.

Sany Heavy Industry closely follows the pace of national strategy and planning, and actively participates in the construction and layout of the national railway and highway networkWet sprayerProduct manufacturing, the launch of Sany high-prototype wet spraying machine, set walking, pumping and spraying in one, with flexibility, less rebound, high efficiency, energy saving in the industry is famous, leading the industry benchmark, contributing to the development of tunnel wet spraying engineering.

At present, the Sany Plateau wet spraying machine is showing its skills on the big stage of the Sichuan-Tibet Railway to help the Century Project to be completed and opened to traffic as soon as possible.

Equipped with a high-prototype engine, the power is even stronger

Strong power: Sanyi Yitz D05 engine is adopted, equipped with plateau program, to ensure that the output power reaches 90kw above 4500 meters above sea level.

Low temperature start: high-power 7.5kw starting motor, preheating with single-stage air intake heating grille, normal start at -40°C.

Low-temperature battery: large-capacity low-temperature battery, -40°C and 360Ah power.

A unique pumping system for more efficient jetting

Inheriting Sany ace concrete pump technology, industry-leading, high-efficiency and energy-saving "not picky eater".

High efficiency: The inclination angle of the pumping system is optimized, the suction efficiency is up to 95%, and the injection displacement is 30m³/h.

Energy-saving: The industry's first casting energy-saving main valve, the pressure loss is reduced by 25%, and the reversing impact is reduced by 10%.

Save money: the transportation pipeline is optimized, which greatly reduces the blockage of the pipe and is not picky; The new concrete piston technology increases the service life by 50%, and the high wear-resistant conveyor pipe technology increases the service life by 2 times.

Sany special chassis is more suitable for all working conditions

It is equipped with a special engineering chassis to adapt to various tunnel construction conditions and complex roads.

Flexible: four-wheel drive and four-steering, crab driving and two-way driving, climbing degree of 47%, turning radius of 5.6m, can pass in narrow tunnels.

Reliable: Hydraulic axles, Deutz engines, Danfoss motors and Rexroth pumps, reliability is guaranteed.

Safety: The cab is FOPS certified; The stability of the outer figure eight legs is good, and the construction is safer.

Fold the telescopic boom for more flexible booms

Wide range: 9 degrees of freedom of the boom, the maximum injection height is 17.5m, the maximum spray width is 30m, and the 240° spherical spray has no dead angle.

Fast movement: the telescopic stroke of the large arm and the small arm is 2m, the small arm is folded at 240°, the number of moving cars is less, and the construction speed is fast;

Accurate positioning: cylinder linkage device, the small arm automatically keeps horizontal, and the nozzle is sprayed vertically on the wall; The first pentagonal cross-section of the big arm has good rigidity, strong and stable.

Low rebound: the manipulator has good rigidity and accurate positioning, and the amount of quick-setting agent and concrete displacement are matched synchronously, and the comprehensive rebound amount is ≤10%.

Upgraded control, hydraulic system, more intelligent construction

Automatic: The amount of quick-setting agent and the pumping displacement of concrete are automatically matched synchronously, and the comprehensive rebound rate is ≤10%;

Intelligent: fault alarm and indicator light prompt, fault analysis is displayed on the display screen, and maintenance warning prompt.

Synchronization: USB data is uploaded and downloaded synchronously.

In addition, in order to adapt to the harsh working conditions such as the plateau, high cold and high altitude of the Sichuan-Tibet line, the Sany Plateau wet spraying machine also comes with a two-stage compression air compressor. The wind is full of pressure! Equipped with special low-temperature hydraulic oil and closed cab to ensure reliable construction in high altitude above 4500 meters and minus 40 degrees Celsius!

"Across the long river of history, from the initial exploration and assumption to the final planning and construction, more than a century of waiting, more than a century of expectation, this railway that witnessed the prosperity of the nation and the rise and fall of the country, this heavenly road that was once thought impossible to build, is becoming a reality with the efforts of the hard-working, brave and fearless Chinese."

As the "number one project" of China's railway construction, the construction of the Sichuan-Tibet Railway is in full swing, as the leader of the construction machinery industry, Sany is committed to scientific and technological innovation, the whole process to help the construction of the Sichuan-Tibet Railway, and contribute to the "natural moat to change the road".

In the future, Sany will continue to practice the corporate mission and responsibility of "serving the country through industry", lead the development of the industry with smarter, more advanced and more reliable equipment, and help create more infrastructure miracles.
