Yanggu Ruilister Engineering Machinery Co., Ltd. was established in 2014, the company is located in the east first of 23rd floor, Aolin Trade City, Yanggu County, Liaocheng City, Shandong Province. Mainly engaged in the production and sales of all kinds of cemented carbide products, such as basic rotary drilling tools, road milling tools, mining shearer tools, rotary digging sleeve, all kinds of joints, drilling tools and so on. The rotary excavator is an integrated drill that can be used for dry digging with a short auger bit or wet digging with a rotary bit and a mud arm. Rotary excavator can be used with hammer drilling hard ground after digging operations. Reaming can be performed at the bottom of the hole with an extended-head drill. Rotary excavator adopts multi-layer telescopic drill pipe, less drilling auxiliary time, low labor intensity, no need for mud circulation slag discharge, cost saving, no pollution, especially suitable for urban construction of the foundation construction. Rotary excavator is mainly suitable for the construction of sandy soil, clay soil, silt soil and other soil layers, in the cast-in-place pile, continuous wall, foundation reinforcement and other foundation construction has been widely used.
