20m Depth Hydraulic Ground Screw Bored Rotary Piling Drilling Rig for Sales

Product DescriptionFoundation Pile Rotary Drilling Rig The machine lock bar rotary pile drilling rig uses hydraulic crawler-type telescopic chassis, self-liftingand folding collapsible drilling mast, telescopic drilling rod and many other technical applications. It isa construction machine suitable for hole formation in building foundation engineering. Mainly suitablefor the construction of soil layers such as sandy soil, cohesive soil, silty soil, etc., it is widelyused in various foundation constructions such as cast-in-situ piles, continuous walls, andfoundation reinforcement.Compared with ordinary rotary drilling rigs, machine-locked rod rotary drilling rigs have many objectiveadvantages, such as the ability to drill through special grounds such as cement ground, hard sandysoil layers, and rock layers. It is suitable for large-scale engineering construction, buildings, high-speed,high-speed rail 3. Railway engineering construction. The machine construction runs fast, has highefficiency, good drilling quality, and is fuel-efficient and durable.  ModelHWDR150D Drilling Diameter(mm)400-2200mm Drilling Depth(m)15EngineYunnei 88KWEngine speed2400 r/min Power head torque22000-30000 N.MPower head speed30-50 r/minMax.lifting force150KnMax.stroke11-22mWire rope diameter18mmRotation angle180 degreeWalking speed40-50 km/hMax.
