2018 spring started busy 5 stars 6 tons of small digging strongly recommended!

In March, the two conferences were in full swing in 2018, and throughout the country, the opening and resumption of roads, railways, and various types of municipal maintenance, pipeline laying and other projects were also actively preparing. Construction machinery represented by excavators will usher in another Sales hot season.

Among them, the small excavation of flexible and compact body is not affected by the narrow operating range, making it play an irreplaceable role in municipal construction. Demand from the market has also prompted major manufacturers to work hard to dig small areas, followed by the introduction of a representative classic small digging machine, which has risen year after year in the proportion of digging machine sales. In 2017, the sales volume of small excavators of 13 tons or less has been maintained at around 50%. In February 2018, there were more than 5,220 units of digging sales, accounting for 47%, and they still maintained an absolute advantage.

"Looking for fascinating eyes", in the face of the small diggers introduced by many brands, "partnership difficulties" of small partners can easily tangled up what brand of equipment to buy for the upcoming start of work season. According to the statistics of recent excavator sales in China, and the “Axis Shopping Mall Inquiry Index”, China Construction Machinery Business Network has selected 5 models of 6t-class small digging machines from among them and started construction soon. .
