The energy saving and emission reduction of construction machinery is on the cutting edge

Zoomlion (000157, stocks) has brought a very hot concept in recent years to the construction machinery industry, that is carbon fiber.

On baumaChina2010, Zoomlion’s stand had a boom that was not mounted on the chassis. This was the first show of the application of carbon fiber technology in concrete pump trucks.

On September 28, 2011, on the eve of the 62nd anniversary of the People’s Republic of China, Zoomlion sent its own 80m carbon fiber jib pump truck, although it did not directly refer to the world’s highest level, but its technical content. But walked in front. On November 18th, Zoomlion's first 62m carbon fiber boom truck was settled in Dalian and received market recognition.

The goal of energy saving and emission reduction has been raised for a long time. Before the company's ideas were mostly concentrated in the field of power systems. On the one hand, the construction machinery industry was the second largest market for internal combustion engines, and it was of great significance to reduce energy consumption; on the other hand, it was how to save energy. Dynamic useless consumption.

These ideas and explorations are all good. However, people have forgotten that the quality of construction machinery products is very large, and they are all driven by large-scale steel. If savings can be realized from materials, this will surely lead people to the construction machinery products. The overall image.

Concrete pump truck is a type of construction machinery product that can be driven on the road. If the product is too heavy, it will not be able to meet road regulations, and the damage to the road surface is also very large. Therefore, how to realize the lightweight design of the ultra-long boom pump truck is one of the common pursuits of global pump truck designers.

Take Zoomlion's 80m carbon fiber boom pump truck as an example. The 80m boom of conventional materials is overweight and requires a chassis with a length of nearly 30m and a total mass of 100t to be carried. This ultra-wide, long product is difficult to meet the road conditions and construction needs, and even the boom can not be normal. If the carbon fiber material is used, the 80m boom will be 40% lighter than traditional materials, and the working moment will be reduced. It will not only be unnecessary to use the ultra-large slewing ring, but it can also be normally installed on the universal 6-bridge vehicle chassis. The length of the vehicle is only 17m. 2.5m wide.

In the “2011 China Machinery Top Ten News” selection, Han Xuesong, chief advisor of the China Construction Machinery Industry Association, commented that Zoomlion really used the concept of energy saving on the cutting edge. The lightweight design of the jib has resulted in a substantial reduction in the quality and size of the entire vehicle. This is the design that can truly represent the direction of energy conservation and emission reduction.

It can be imagined that, in 2011, the realization of operating income of 500 billion yuan in the entire industry, how much steel, rubber and other resources to consume, the proportion of raw material costs in operating income should be how much?

Some people think that excavators, cranes, bulldozers and other products need a lot of machine weight to complete their normal construction. However, people once knew about pump trucks. The application prospects of new materials and new designs in product design are immeasurable. At present, we are very pleased to see that Zoomlion and Shandong Linggong have started to work hard on materials and design. In the future, we hope that more companies will turn their attention to this aspect and achieve greater energy savings in the industry. Row achievements.
