This product is an integrated drilling rig. The maximum drilling depth of the drill is 30m, and the drilling diameter is 500-1600mm. Different bits can be selected. The short auger can be used for dry excavation, while the rotary drill can be used for wet excavation. Rotary excavators with a hammer can be used to drill holes in hard formations, and if a drilling tool is used, it can expand at the bottom of the hole. Rotary excavator adopts multi-layer telescopic drill pipe, which has the advantages of short support time, low labor intensity, no sludge discharge and cost saving. It is especially suitable for urban infrastructure construction.
