Today is the solar term of light cold. As the saying goes, "when the light cold is at 239, the weather is cold and cold to shake". With the arrival of cold winter, many places in the north have ushered in snow, and the task of snow removal is very arduous. Professional ice shovel and snow removal machinery has become a sharp weapon in the ice and snow world.
after the blizzard, I'll show you the mechanized snow removal scene
Not long ago, a heavy snow in Urumqi lasted one day and one night, with the thickest snow exceeding 15 cm. 120 snow truck drivers fought continuously for 15 hours. All the places swept by snow trucks on the main roads of Urumqi were quickly cleaned up.
The length of the roller brush equipped on the snow removal vehicle has increased to 3.6 meters, and the speed is fast to 410 revolutions per minute. There are more than 30 kilometers of road sections to be cleaned by the snow removal project department, with a snow area of nearly 1.2 million square meters, which is equivalent to the area of three Tiananmen Square, but 65 snow removal vehicles can clean the road covered by the heavy snow in six hours.
If such a heavy snow had fallen a year ago, it would take the whole city at least a week to clear the snow and resume normal traffic. Now, in addition to snow removal vehicles, there are sliding machines, snow lifters and snow shovels. The snow removal process has a full sense of science and technology.
In 2021, the demand for snow removal equipment increased rapidly. Especially since the autumn, enterprises producing and developing snow removal equipment have been particularly busy.
Li Guojin, general manager of XCMG (Liaoning) Marketing Company
Li Guojin was responsible for the sales of construction machinery vehicles in Xuzhou before. It was his first contact with snow removal vehicles. He didn't expect that the factory in Fuxin had orders in the first year of operation. In 2021, more than 1100 comprehensive snow removal vehicles and various hanging snow removal machines and tools have been sold.
While the production and sales are booming, the company's R & D team is also working hard to upgrade the technology of new products. Their newly developed snow thrower can instantly throw the snow accumulated into a half meter high 30 meters away, break it into small ice slag and scatter it on the ground.
This high-efficiency snow thrower can throw 2500 tons of snow an hour. Basically, after the car drives, 70% and 80% of the snow on the road can be removed.
Tian Pengxin, director of quality management department of XCMG (Liaoning) Machinery Co., Ltd
Now, the new generation of snow throwing machine they are developing can throw about 4000 tons of snow per hour, and the snow throwing distance can be increased to 60 meters away.
Cao Yongguang, deputy director of technology R & D Department of XCMG (Liaoning) Machinery Co., Ltd
Before 2008, the snow removal equipment of overseas brands almost monopolized the Chinese market. Not only the sales price was expensive, but also the operation and maintenance cost of users was very high. XCMG group where Cao Yongguang is located has a keen insight into the broad market of snow removal equipment in China, has arranged a production and R & D base in Northeast China, and has embarked on the road of R & D and manufacturing of independent brand snow removal equipment.
According to the different amount of snow and terrain in the north and south, Cao Yongguang has developed 105 models of various snow removal machines and comprehensive snow removal vehicles. At present, the high-end snow removal equipment industrial base being built by XCMG in Fuxin, Liaoning focuses on the R & D and manufacturing of high-end snow removal equipment.
Wang Jian, general manager of XCMG (Liaoning) Machinery Co., Ltd
As early as the 1920s, snow and ice removal equipment had appeared abroad. For a long time in the past, only foreign brands could be seen in the market of ice and snow removal equipment in China. Some high-end overseas brands take China as a major market for layout.
from "big man" to "little smart", domestic snow removal equipment shows its talents
International snow removal equipment companies focus on the Chinese market, and China's construction machinery manufacturing enterprises are not down. A multifunctional snow removal vehicle developed by a construction machinery manufacturing enterprise in Changsha, Hunan Province is small and has a smart "brain". It is equipped with lidar, depth camera, ultrasonic and other functions. It can be operated remotely and driverless. It is good at working in narrow back streets and alleys.
Matching with intelligent snow removal vehicles, the enterprise has also developed a complete set of intelligent sanitation cloud platform, which can manage big data in snow sweeping and street cleaning.
The company's products also include high-pressure cold wind snow blowing vehicles weighing up to 18 tons. Before Chinese enterprises developed this equipment, the price of similar foreign products exceeded one million yuan.
The snowblower, as its name implies, is to use strong wind to blow the snow clean. The wind speed of this high-pressure cold wind snowblower can reach 125 meters per second at the peak, and the central wind speed is equivalent to three to four times that of level 12 typhoon.
In the past, their users were concentrated in the north. Now, with some extreme weather, southern cities are also ordering ice and snow removal equipment from them. Especially in 2021, the increasing demand for ice and snow removal equipment all over the country also doubled the pressure on the company's production workshop.
Ice and snow removal equipment is an emerging field of construction machinery. Chinese construction machinery enterprises continue to move towards specialization and intelligence in the R & D of ice and snow removal equipment.
[half hour observation] innovation casts the road of high-quality development
In the field of construction machinery, we know that China's cranes, excavators, shield machines and other large equipment have strong strength in the past. In today's program, we see specialized, refined and characteristic construction machinery such as snow throwing vehicles, snow removal Siasun Robot&Automation Co.Ltd(300024) and snow removal machines. Chinese enterprises are also exploring new ways and catching up. To usher in high-quality development, made in China needs such demand-oriented innovation. We expect that made in China can blossom in all fields and inject a source of power into promoting high-quality economic development and building a new development pattern.
