1.The brief introduction of 13.5 meters wheeled rotary pile drilling rig 13.5 meters wheeled rotary pile drilling rig is a kind of rotary pile drilling rig, which is suitable for building construction foundation. It is widely used in the construction of various soil layers, such as sand, clay, silty soil and so on. At the same time, it is widely used in the construction of cast-in-place piles, continuous walls, foundation reinforcement. The small rotary drilling rig has the characteristics of low noise, small vibration, large torque, muti-function, fast drilling speed, flexible in operation, high construction efficiency, various speed regulation, electronic automatic monitoring.These characteristics gradually replace some traditional piling and drilling equipment. 2.The technical parameters of 13.5 meters wheeled rotary pile drilling rig Model XWL-13.5 Work pattern oil cylinder force wire rope deadweight Drilling hole diameter mm 500-1500mm Drilling depth m 13.5 10-26 External dimension m 7.7*2.2*3.0 Weight t 8 Tire type / 900-20 Engine model / 4108 power kw 88 rotating speed r/min 2400 Power head torque kn.m 17000-22000 Power head rotating speed r/min 30-50 Maximum lifting power kn 150 Maximum stroke m 11-22 Wire rope diameter mm 16 Rotation angle ° 180 Moving speed km/h 20-30 Maximum grade ability ° 25-30 (In the continuous improvement of products, technical parameters are based on practical consultation.)
