LB 36 DRIVING SHELL

LB 36 DRIVING SHELL – Heavy-Duty Coupling for Maximum Drilling Torque

In rotary drilling operations, reliability isn’t optional—it’s everything. The LB 36 DRIVING SHELL serves as the essential mechanical link between your Kelly bar and the rotary drive of large foundation rigs. Designed for seamless torque transfer, precise alignment, and extended durability, this component stands at the heart of bored piling performance for elite drilling machines like LIEBHERR LB 36 and compatible models across BAUER, SOILMEC, SANY, and XCMG platforms.

Built for rugged terrain, deep foundations, and extreme torque loads, the LB 36 DRIVING SHELL is engineered and manufactured by 3GEN Export, your global OEM supplier for reliable heavy equipment spare parts.

What Is the LB 36 DRIVING SHELL?

The LB 36 DRIVING SHELL is a high-strength steel adapter mounted directly onto the rotary head of a drilling rig. It functions as a torque coupler, transferring the powerful rotational force from the rig’s rotary drive to the Kelly bar, which in turn operates drilling tools such as augers, core barrels, and buckets.

Its job is simple—engage, align, and rotate—but the engineering required to do it under 500+ kNm torque is anything but simple. That’s why every LB 36 DRIVING SHELL is machined with pinpoint accuracy, treated for extreme wear resistance, and rigorously tested under simulated field conditions.
