Rotary drilling rigs, small pile drivers, long auger rotary drilling rigs, and solar-powered rotary drilling rigs are generally classified into small, medium, and large machines according to their drilling depth.#hydraulic crawler drilling rig#
The principle for choosing a rotary drilling rig (small pile driver, long auger rotary drilling rig, or solar-powered rotary drilling rig) should be to meet the user's main project needs while also considering potential future project requirements. The rotary drilling rig (small pile driver, long auger rotary drilling rig, or solar-powered rotary drilling rig) is used in operation. Rotary drilling rigs in operation | Small pile drivers | Long spiral rotary drilling rigs | Solar rotary drilling rigs Based on their main working parameters: torque, engine power, borehole diameter, borehole depth, and overall machine weight, they can be divided into three types: Torque 100kN·m. Engine power 170kW, borehole diameter 0.5~1m, borehole depth approximately 40m, overall machine weight approximately 40t. Small machine application market positioning: (1) Slope protection piles for various buildings; (2) Partial load-bearing structure piles for buildings; (3) Various piles with diameters less than 1m in urban renovation municipal projects; (4) Piles suitable for other purposes. The market workload coverage of small machines reaches over 30%. Folding medium-sized machine Torque 180kN·m, engine power 200kW, borehole diameter 0.8~1.8m, borehole depth approximately 60m, overall machine weight approximately 65t. href=rotary drilling rig|small pile driver|long spiral rotary drilling rig|solar rotary drilling rig" alt="rotary drilling rig|small pile driver|long spiral rotary drilling rig|solar rotary drilling rig"

The application market positioning of medium-sized machines:#hydraulic crawler drilling rig#
(1) Bridge piles for various highways, railways and other transportation facilities;
(2) Load-bearing structure piles for large buildings and port terminals;
(3) Bridge piles for elevated bridges in cities;
(4) Other applicable piles. The market workload coverage of medium-sized machines reaches more than 90%.
Large machine
Torque 240kN·m, engine power 300kW, drilling diameter 1~2.5m, drilling depth 80m. The total weight of the drilling rig is more than 100t. The application market positioning of large machines:
(1) Extra-large bridge piles for various highways and railways;
(2) Special structural load-bearing foundation piles for other large buildings. Large-scale rotary drilling rigs account for over 10% of the market workload.
Selecting the appropriate rotary drilling rig (small piling machine, long auger rotary drilling rig, solar-powered rotary drilling rig) based on different usage environments is crucial.#hydraulic crawler drilling rig#
