Applicable for all strata that suit rotary drilling rig, especially for those complex strata in which are difficult to make wall protection, such as pebble, silt, quicksand, fragmented, karst cave, backfill, swamp, lake, river etc.
AFECZX series, or "Long" type, are usually mounted to a crane and ideal for boring large diameter, deep piling shafts in variable or indeterminate soil conditions where there is risk of collapse. All models of this serie
