According to the main working parameters: torque, engine power, drilling diameter, drilling depth and weight the piling rigs can be divided into three types, applied to different civil engineering project.

1.Small Piling Rig

Small Piling Rig

Rated output torque: 100kN·m, engine power: 170kW，drilling diameter: 0.5～1m, drilling depth around: 40m，total weight around: 40t, the main application of small piling rig:

Application of small piling rig market positioning:

1)The slope protection pile for various of buildings;

2)Part of the building bearing structural pile;

3)Various piles with diameters less than 1m for city's urban renewal projects;

4)Used for other piles, the market workload of small piling rig covers more than 30%.

2.Medium Piling Rig

Rated. output torque:180kN·m, Engine power:200KW, Drilling diameter:0.8-1.8m, Drilling depth: 60m, Total weight :65t.

Medium Piling Rig

Application of medium-sized machine market positioning:

1)Bridge piles of various highways, railways and other transport facilities      

 bridges;

2)large-scale construction, port load-bearing structure of the pile;

3)City viaduct bridge pile;

4)Other applicable piles. Market coverage ratio of medium-sized machines work is more than 90%.

3.Large-scale Piling Rig:
