The hottest excavator is becoming more and more in

  • Detail

Excavators are becoming more and more intelligent. Excavator drivers are not far from unemployment

at the end of the year, it's time to summarize and count again. Here is an inventory of foreign excavators. This year, many manufacturers actually launched some new products, but most of them were only minor improvements and upgrades. It seems that it is not meaningful to list them. Generally speaking, excavators have been very stable. In fact, we are more concerned about the new technology used in excavators

since it is a new technology, it doesn't have to be as high as 10 ℃ in serious cases. It should be limited to shelf goods. Cutting edge technologies may not be available for products on the market yet, but they still need our attention. First, let's look at the excavator with 3D printing. Of course, we admit that this name is problematic. In fact, it is just an excavator with some 3D printing parts

this excavator unveiled on CONEXPO in Las Vegas is only a concept machine, and only the cab shell, forearm, hydraulic oil tank, radiator and other components are 3D printed. However, it does not prevent us from paying attention to the application of 3D printing. 3D printing is undoubtedly an advanced manufacturing technology. Of course, there are still shortcomings such as high cost and long production cycle

in the future, 3D printing technology is bound to gradually overcome some shortcomings, that is, the acquisition of signals. Some parts that are now expensive due to complex technology may be produced by 3D printing. Because the technology is simplified, the price is no longer a constraint. 3D printing can also be used to manufacture parts that have been discontinued. Of course, the future application of 3D printing in excavators mainly depends on how the manufacturer calculates the economic account to see which parts are more suitable for 3D printing

let's look at Volvo's electric concept excavator ex2. Although it is only a concept machine, the applied technology is revolutionary with a small stroke of this kind of experimental machine. The biggest feature of this machine is that it is fully electric. It uses not only batteries as the power source, but also various electrical components to replace the hydraulic system, which no longer requires energy conversion and complex hydraulic control system, and is directly driven by electric energy

ex2 subverts the traditional understanding that the excavator does not necessarily need a hydraulic system. It is no problem that the walking and slewing can be driven by motors, but the hydraulic cylinder of the working device has also been replaced, which is a little surprising. Some people doubt the effect, but ex2 works no different from ordinary excavators, giving birth to the endogenous development momentum of private enterprises, but it is quieter. If these technologies are further developed and put into the market, it will undoubtedly bring a revolution to the traditional excavator

Carter's new generation excavators 320 and 323 are worth mentioning. Although they were first launched in China, they were soon released in Europe and North America. So we should be familiar with these machines. I won't go into details here, but just check the technologies that didn't exist before. The weighing function was not used in excavators of this level in the past. Those who need this function can only add third-party products, but now the manufacturer has built it in, which is really a breakthrough. Of course, in addition to the above two models, Carter's current F series also has a built-in weighing function

in addition, slope control and cancellation of hydraulic pilot are technologies that have existed before, and cannot be regarded as the latest technology. However, another innovation of the new generation of excavators is the use of electronic fans, which also increases the generator capacity. The above-mentioned armor has been introduced, so I won't elaborate here

finally, there have been a few changes in hybrid excavators that have not been particularly popular in recent years. Both Shengang and Hitachi have come up with products that use lithium-ion batteries as energy storage components. Lithium ion batteries are relatively cheap, which is conducive to reducing the cost of hybrid excavators
