As a full hydraulic crown pin model, sany full hydraulic series in 2019 also continue to be popular, the majority of customers favor! As the saying goes, “ Customers are the bread and butter of the enterprise ” . And sany hydraulic is good, have the final say or sany customer.
Next, we look at the sany hydraulic all over the country in the performance of the construction projects, listen to the customer how to say!
1, highway construction project of provincial highway 201 in hulunbuir city
& other; The mechanical pressure is 6 times and the trinity full hydraulic pressure is only 5 times.
project background
The highway construction project of provincial highway 201 in hulunbuir city of Inner Mongolia autonomous region is an ldquo in the highway network of Inner Mongolia autonomous region. Three horizontal and nine vertical ” An important component in a column.
analysis of working conditions
The project is located in hulunbuir grassland, passing through the area of swamp, permafrost and other complex terrain, road sand and stone layer and water stability layer of pressure has a high demand.
construction effect
Sany all-hydraulic single steel roller adopts double-frequency and double-amplitude vibration mode with large excitation force and smooth compacted road surface, which is superior to mechanical type in terms of construction efficiency, after-sales service and maintenance cost, and has been highly praised by customers and project leaders.
& have spent 
& other; Before the use of mechanical need to press the road 6 times, now the use of trinity full hydraulic pressure as long as 5 times can be. Throughout the &; a field leader of the project said that he was impressed by the high pressure efficiency of sany all-hydraulic roller.
& have spent 
Sany full hydraulic roller has a strong traction and excellent quality, very suitable for the local extreme conditions, but also in line with the construction standards of national major projects.
2, sichuan lianghekou hydropower station construction
& other; Round-the-clock operation
project background
The lianghekou hydropower project in yajiang county, sichuan province is considered to be the most complicated and highest earth-rock dam hydropower project in the world, and it is a state-level project that receives much attention.
analysis of working conditions
The construction height of lianghekou dam is 296 meters, the average thickness of rockfill is 80cm, and the thickness of each layer of core wall is 30cm. It needs equipment to roll back and forth for dozens of times, which requires the equipment to have a strong rolling pressure and traction force to ensure that the crushing effect reaches the standard.
construction effect
In this project, the main construction sites of sany full hydraulic roller are clay construction, dam rockfill construction and core wall construction. Due to large construction area and tight construction period, the roller works 24 hours a day.
& have spent 
& have spent
▲ clay construction
the project leader said that the mechanical roller was chosen for the construction of lianghekou because the operation process was troublesome and the compacted road surface was far from smooth with full hydraulic equipment.
& have spent 
& have spent
▲ dam piling construction
In the construction of the dam, 11 31-ton rollers took part in the core of the dam. Sany 26t roller is responsible for the core wall clay layer, and 33t roller is responsible for the rockfill layer.
3 key projects in guangdong province “ North third ring highway ” The construction of the
& other; 147kW high power engine, more powerful power ”
project background
The second phase of guangzhou north third ring expressway is a key construction project of guangdong province and guangzhou, connecting guang-hui, huan-guan, beijing-zhuhai, airport and dagan-guangzhou expressways as well as several national, provincial and trunk highways.
analysis of working conditions
This project is a provincial and municipal key project, and the geology of the high cut slope is complicated, the rainy season lasts for a long time, and the construction side has very strict regulations on the equipment in the field.
construction effect
& other; North third ring highway ” The conTractor of the project, guangzhou lukun road engineering co., LTD., used sany full hydraulic roller construction.
According to the project leader, the two ssr220ac-8 have been working on the project for more than three months, with almost no pause in the forward and backward commutation. They have been under construction for more than 10 hours every day, and the pressed road surface is also very smooth.
& have spent 
& have spent
▲ sany full hydraulic roller rolling back and forth
In addition, sany ssr220ac-8 full hydraulic roller adopts 147kW high-power engine with strong power, dual-frequency and dual-amplitude vibration mode, which has greater excitation force. Compared with other brands, the efficiency of the same compactness road surface can be improved by 16.7%.
& have spent 
In addition to the excellent performance of the equipment, sany roller in the maintenance is also very convenient, all the filter elements are at your fingertips; Main oil pump rear, very convenient maintenance, all designed to make the maintenance more convenient.
sany always takes the lead in building China, contributing the latest technology and products to the country. since the beginning of entering the roller industry, sany has been focusing on the r&d and manufacturing of full hydraulic rollers, relying on solid quality and the completion of a project of excellence.
sany hydraulic roller with the word of mouth, created a strong influence in the domestic roller industry, now, many customers in the industry have been known: Buy full hydraulic roller, look for trinity! Throughout the &;
