Full displacement drilling BAT 300 V- T A Performance data Rotary drive - torque kNm Above drilling depths are valid for the use of standard tools and for the X value of 530 mm shown in the illustration. * Other drilling diameters on request ** With 10 m Kelly extension

Performance data Rotary drive - torque kNm Above drilling depths take into account that an auger cleaner is used and the cardan joint has been removed. Above drilling depths are valid for the use of standard tools and for the X value of 340 mm shown in the illustration. * Other drilling diameters on request ** With 10 m Kelly extension

Performance data Rotary drive I - torque kNm Above drilling depths are valid for the use of standard tools and for the X value of 520 mm shown in the illustration. Due to differences in the max. admissible load capacities, the combinations of drilling depth and drilling diameter may be limited. * Other drilling diameters on request ** When using a protective hose, the maximum drilling depth has to be reduced by 875 mm

Performance data Kelly bars Rotary drive - torque kNm Other drilling diameters available on request. When using a casing oscillator, value X must be reduced by 1500 mm. * Depends on the design of the casing driver * Installation only possible with assist crane

Above mixing depth is valid for the use of standard tools and for an X value of 705 mm (see above illustration). * If the mixing diameter is 1900 mm or more the mixing paddle is always located below the leader. Other drilling diameters available on request '* With 10 m Kelly extension

Performance data Static moment kgm Above pile length is valid for an X value of 500 mm (see above illustration).
