A number of technical problems have been overcome, and the sales momentum of SANY micro-digging is strong

In May, SANY micro-digging SY16, SY35 has created 31 months of network sales of 31 units, an additional 10 units, sold out in 8 days.

It is highly praised by the market and loved by customers. It is the demand for excellent quality or what is needed in the market. There are also both. The following small series of “Big Brothers” will show you the “excellence” of these two products.

Yu Hongfu, chairman of Sany Heavy Machinery, said that the downlines of SY16 and SY35 have improved the type spectrum of the Sany earth-rock machinery and are of great strategic importance to Sany.

It is understood that the SY16 and SY35 are the two smallest hydraulic excavators currently used by Sany with a weight of 1.6 tons and 3.5 tons. They are widely used in small-scale earthwork operations such as manor, farm, city corners, and side gutter dredging. Lifting, crushing, and dozing operations.

As a product created by Sany in the micro-digging machine, SY16 and SY35 have a full, sleek appearance without sacrificing strength. They are clearly distinguishable from other small and small excavators. They look more compact and flexible.

According to Wang Chunhui, the person in charge of research and development, the R&D team is required to implement the standard small digging function in a very limited space when designing the overall layout of the two excavators, and also includes a boom deflecting mechanism that is not provided by the standard small digging. At the same time, it is also necessary to ensure good maintenance performance, smooth and efficient heat dissipation performance, and many problems that do not arise in the layout of large excavators or small excavators at the tail end of the standard, but they are all properly resolved.

Conquer the two major problems of "shock absorption and heat dissipation"

In terms of performance, Wang Chunhui is full of confidence: “SY16, SY35 have achieved a major breakthrough in handling performance, high micro-motion performance, coordinated action, soft and small impact. At the same time, high-quality hydraulic components with the Sany in the hydraulic The years of experience in system design have not only improved the overall handling performance, but also ensured extremely low failure rates."

In order to develop this new product, Wang Chunhui led the R&D team to conquer two major difficulties. One is the vibration problem. As a mini-digging, which is mainly used for urban operations, the vibration noise and other comfort issues are the most important issues. During the product development process, from the optimization of the engine and cab suspension to the cushion design, to the simulation of the cab wall structure, each step of the R&D team has been repeatedly verified through theoretical calculations and experimental tests.

The second is the heat problem. The tailless structure determines that the engine compartment space is very narrow, and the compact layout is more prone to heat balance problems during excavator operation. Through the wind tunnel flow field optimization project in cooperation with universities, Trinity digging R&D personnel carried out multiple optimizations on the air flow field of SY16 and SY35, and redesigned the radiator to improve the heat dissipation performance, achieving a small size and large heat dissipation.

“Machine production is not constrained by work intensity and can withstand loads that are tens or even hundreds of times higher than artificial ones, saving labor resources to a great extent and greatly increasing production efficiency. A 31-micron excavation is equivalent to the workload of 18 people. ,Can save about 50,000 yuan for the customer in the year." Tang, Manager of Sanyi Interactive Marketing Center said.

In addition to excellent quality, Sany Micro-Digging has clearly reached the market demand point, micro-digging sales skyrocketed, becoming the leader in the construction of small-scale earth-moving engineering, is the choice of the market, but also the customer's affirmation of the Sanyizou micro-digging quality.
