BG 20/18 DRIVING SHELL

BG 20/18 DRIVING SHELL – Precision-Engineered Pile Driver Component for Heavy-Duty Foundation Work

The BG 20/18 Driving Shell is an integral component in bored pile drilling systems, especially suited for high-performance applications involving deep foundations. Crafted for exact compatibility with BAUER’s renowned BG 20 and BG 18 rotary drilling rigs, this driving shell serves as a transition interface between the Kelly bar and the casing or drilling tool. Its primary function is to ensure maximum torque transmission, vertical load handling, and seamless alignment under extreme drilling conditions.

Manufactured to OEM-level precision, this steel shell is built to perform in rugged environments where accuracy, endurance, and safety are non-negotiable. Whether used in bridge foundations, building piles, or infrastructure projects in mixed soil and rock layers, the BG 20/18 Driving Shell ensures consistent, secure coupling and optimal drilling performance.

What is a BG 20/18 DRIVING SHELL?

The BG 20/18 Driving Shell is a high-strength mechanical interface component that links rotary torque from the drilling rig’s Kelly bar to the casing pipe or drilling bucket. Positioned at the top of the drilling string, this shell bears both rotational and vertical loads, making its durability and precision engineering critical for safe and efficient operation.

Built with hardened steel and precision-machined openings, the BG 20/18 Driving Shell accommodates bolted or slotted connections for quick locking. The structural integrity of this shell ensures that it withstands high torque and axial stresses — especially during rock penetration or deep drilling phases.

Compatible Drilling Rigs

The BG 20/18 Driving Shell is specifically designed for optimal compatibility with the following rotary drilling rigs:

BAUER:

• BG 20: Ideal for mid-to-large foundation projects requiring high torque transmission

• BG 18: Designed for smaller footprint job sites with tight access but needing robust drilling capacity

While this part is customized primarily for BAUER rigs, it can also be modified upon request for cross-compatibility with other machines used in conjunction with SOILMEC, LIEBHERR, SANY, and XCMG rigs — provided proper coupling measurements and torque specifications are submitted.
