As a widely used and precise construction equipment, the drum cutter has excellent performance in mountain excavation. In Yuyao City, Zhejiang Province, a construction site is using Yichen transverse drum cutter for mountain excavation. The mountain is composed of compacted soil, mudstone, limestone, tree stumps, etc. Soil and mudstone have lower hardness and are easier to operate. But the hardness of limestone is high, the bucket can’t dig it, and the hammer can only punch holes one by one. Moreover, there are high-voltage wires above the mountain, and explosives are not allowed to blast. Faced with such a complicated working condition, Mr. Wu, the construction party, chose the YF-30RW drum cutter of Yichen Company, and installed it on the LOVOL Lovol 260 excavator. The drum cutter has a very high milling and digging efficiency. The performance shocked Boss Wu and his wife. The wife sighed and said: It would be great if there was this product when Yugong moved mountains.
