Shanhe Intelligent's first rotary drilling rig is as strong as new

Breaking the monopoly of foreign technology, and starting to regain the "first shot" of "lost land" and shouldering the burden of creating the first-generation rotary drilling rig of the national brand. Have you seen it?

If someone tells you that there is a domestic rotary drilling rig that has been "served" for 16 years and is still in normal use, would you believe it?

Don't believe it, you really have it. It is the first rotary drilling rig SWDM20 of Shanhe Intelligent!

One day in early October 2019, at a construction site in Loudi, Hunan, we saw this prestigious rotary drilling rig. Standing next to the love machine, the owner Zhou Aitu pointed to the individual components: "Power head main pump, main valve, motor, travel motor, reducer, chassis, structural parts, still the factory parts in 2002." These main Although the parts have been baptized in the years, they still maintain stable performance and good appearance.

“I originally purchased this rotary drilling rig because I was very trustful of Mr. He’s technical ability. Unexpectedly, its performance exceeded my expectations. This SWDM20 rotary drilling rig has good stability and rock-input capability. Strong, but also very fuel-efficient." Zhou boss is very proud of the original choice.

“Unlike other domestic enterprises to modify the imported excavator chassis, Shanhe Intelligent Research and Development rotary drilling rig, the first step is the technical route of self-developed self-made chassis, the stability of the rotary drilling rig is higher, and the chassis can also be developed with their own tops and The working device achieves the best match.” Zhou Bo has been engaged in the construction machinery industry for many years, and his understanding of the rotary drilling rig is quite rational and mature.

Let Zhou’s boss relish the fact that this “old” equipment accessory can be easily purchased now, unlike some brands, many matching parts of old products, and now must be customized. This saved him a lot of heart and saved him a lot of maintenance costs.

In fact, the R&D and production of domestic rotary drilling rigs started late. Until the end of the 20th century, China's rotary drilling rigs mainly relied on imports to develop the “Made in China” rotary drilling rig, which became the dream of people with lofty ideals in domestic construction machinery.

In 2001, He Qinghua, the chairman of Shanhe Intelligent, personally took the lead and set up a rotary drilling rig project team to focus on the core technology of rotary drilling rigs. In 2002, Shanhe Intelligence became the only host manufacturer in China that had independent intellectual property rights and was able to independently develop rotary rig control software.

In 2002, Shanhe Intelligent's first rotary drilling rig SWDM20 came out. This gathering of Shanshanhe intelligent innovation technology and internationally renowned brands in a rotary drilling rig has aroused great concern in the industry. What is its performance, can it fight over the foreign brands? Can it set off the banner of the Chinese national brand of rotary drilling rigs? There are many doubts.

In March 2003, Shanhe Intelligent's first rotary drilling rig, which received much attention and shouldered heavy burdens, went to Hexi Power Plant in Inner Mongolia to accept the test of the market and open its legendary life with beautiful actual combat data.

Won the fame! The hole diameter is 1.8m, the pile depth is 50m, and the hole forming time is less than 5h. This is the first show of Shanhe Intelligent's first rotary drilling rig SWDM20. All previous doubts have been broken by actual results. In the following 16 years, this Shanhe intelligent circular excavation "Big Brother Machine" has been transferred to the Capital Airport, Bird's Nest, Wuyi Expressway, Wuhan-Guangzhou Railway, Changsha Metro and many other large-scale projects, from north to south, from west to east, it It has withstood various complex geology tests such as quicksand, silt, backfill soil layer, shallow sand pebble layer and multi-dissolved lime layer. It has shown high working efficiency and super rock drilling ability. "From the current point of view, I don't think there will be any big problems with this rotary drilling rig for another 16 years." Zhou said with a smile.

The foreign brand has unified China's rotary drilling market, and now the foreign brand is almost extinct. The Chinese construction machinery, represented by Shanhe Intelligence, has been using the struggle of more than ten years to dig the rig of the “Heavy State of the Country” and firmly grasp it. The Chinese are in their own hands. Now, China's rotary drilling rigs have not only successfully recovered the market, but also destroyed the city around the world, screaming the "Made in China" screaming around the world.
