BAT 450.1 Rotary drive (BAT series)

The powerful rotary drive delivers the required torque for common drilling applications such as Kelly, continuous flight auger or full displacement drilling. Considerable advantages are the automatic torque regulation as well as four electronically adjustable speed ranges. The rotary drive is powered by the on-board hydraulics of the LRB 355 carrier machine. Designed for continuous operation, the rotary drive enables especially fast drilling cycles.
Torque 450 kNm
Speed 40 U/min

Features

Automatic gearbox

Applications

Kelly drilling

Kelly drilling

Kelly drilling belongs to the most common dry rotary drilling methods. Soil and rock material is conveyed to the surface discontinuously with relatively short rotary drilling tools. more

Continuous flight auger drilling

Continuous flight auger drilling

The loosened soil material is continuously conveyed to the surface using a continuous auger, the so-called continuous flight auger. more

Full displacement drilling

Full displacement drilling

Full displacement drilling is a modification of continuous flight auger drilling. The drilling tool used is a smooth pipe with an auger-type starter piece. more

Down-the-hole drilling

Down-the-hole drilling

For down-the-hole drilling a hammer is mounted on the lower end of a drill rod. The hammer is activated by adding compressed air. more

Wet soil mixing

Wet soil mixing

For wet mixing a self-hardening suspension is introduced into the ground. more

Dry soil mixing

Dry soil mixing

For dry mixing a binding agent is introduced into the ground as powder. more
