"Heavy" construction machinery enterprises that are difficult to bear on asphalt roads call for wheeled excavators to play
Track-type excavators can easily cause damage to asphalt pavements, and local construction machinery companies have called for more introduction of wheeled excavators in market road construction.
On the morning of the last working day before the National Day, the author saw at the ground floor of Guanggu Avenue at the intersection of Guanggu Avenue and the Third Ring Road that at least 6 crawler excavators stopped at the roadside “rest†within 200 meters. There are 2 big guys who are 20 tons. According to people familiar with the matter, there will be more crawler excavators on site during the construction peaks in the afternoon and evening. There are many obvious traces of track rolling on the asphalt pavement. To repair these scars, special machinery is needed to cut the surface of the asphalt by 2-3 cm and then re-paving.
Yang Yihua, chairman of the Maxima Machinery Supply Chain Co., Ltd., said that there are about 20,000 excavators in Wuhan, of which more than 95% are crawler. Crawler excavators are easy to damage the road because they are slow to drive, and they are also prone to traffic jams. In addition, wheeled excavators need to be licensed (the crawler excavators do not need to be licensed), and the management is more standardized.
Wheeled excavators are the product of urban development to a certain stage. At present, industrialized country wheeled excavators account for more than 30%. Domestic cities such as Beijing, Chongqing and Shijiazhuang are in front. For example, 40% of small excavators in Chongqing are rounds. Style.
Yang Yihua said that a 20-ton crawler excavator is priced at 800,000-900,000 yuan, and wheeled excavators cost about 100,000 yuan, but the latter can save a lot of trailer costs during use, more importantly. It protects the road surface.
According to the relevant provisions of the "Regulations on Urban Road Management": Tracked vehicles and iron-wheeled vehicles are prohibited from driving on urban roads within the scope of urban roads. Yang Yihua suggested that Wuhan should gradually increase the proportion of wheeled excavators and use suitable excavators for different road conditions. For example, crawler excavators can be used inside the construction site; wheeled excavators are used on asphalt roads.
