LB 28 DRIVING SHELL

LB 28 DRIVING SHELL – Precision Power for Rotary Drilling Performance

In the foundation drilling industry, where millimeter-level accuracy meets megaton torque, the components you rely on must deliver both strength and precision. The LB 28 DRIVING SHELL is one such component—designed specifically for rotary rigs like the LIEBHERR LB 28, this driving shell is a core part of the power transmission system between the rotary head and Kelly bar, ensuring effective torque transfer and reliable performance in the most demanding soil conditions.

Manufactured with uncompromising quality standards by 3GEN Export, the LB 28 DRIVING SHELL is engineered for longevity, stability, and compatibility with the world’s top rotary drill rigs, including BAUER, LIEBHERR, SOILMEC, SANY, and XCMG.

What Is an LB 28 DRIVING SHELL?

The LB 28 DRIVING SHELL is a heavy-duty steel adapter positioned at the rotary interface between the rotary drive and the upper Kelly box. Its purpose is to transmit torque efficiently and safely, especially under high compressive loads encountered in deep bored pile applications.

Crafted with exacting dimensions and balanced geometry, this driving shell ensures seamless coupling, minimal vibration, and reliable alignment of Kelly bars, resulting in more effective drilling with less wear on machinery.
