The principle of choosing a Rotary Piling Rig should meet the major engineering requirements of the user and take into account the possible engineering requirements. Rotary piling rig can be divided into three types according to its main working parameters: torque, engine power, drilling diameter, drilling depth and the quality of drilling rig:
Small type: Torque 100kN • M. The power of the motor is 170kW, the drilling hole diameter is 0.5 to 1m, the drilling depth is about 40m, and the quality of the drilling machine is about 40T.
Application market positioning of small rotary piling rig:
(1) All kinds of slope pile blocks;
(2) Partial bearing structure pile of building;
(3) All kinds of piles with diameters less than 1m are used in urban reconstruction projects;
(4) Piles for other purposes. Minicomputer market workload coverage rate of more than 30%.
