Atlas Copco/Chicago Pneumatic Hydraulic Post Driver Accessories

A hydraulic post driver only fits the post it is capped for, and Atlas Copco and Chicago Pneumatic share accessory sets across matched models. The Atlas Copco KAPD-23 takes an adjustable T-post chuck plus 1-3/4 in. round, 1-1/2 in. square, and 1 in. ground rod drive caps. The 80 lb class LPD-HD and CP PDR 95R take a guide tube adapter for pipe and pile up to 5-1/2 in. OD. Drivers are listed under Atlas Copco hydraulic post drivers and Chicago Pneumatic post drivers, and run off a hydraulic power pack.

KAPD-23 Chucks and Drive Caps

The KAPD-23 chuck grips and aligns the post so impact lands on the centerline; drive caps sit on top of what the chuck cannot grip. The square cap is machined in Denver with a square recess for Telespar and other square profiles so the post cannot twist, and the ground rod cap keeps a 1 in. rod from mushrooming.

Match the Accessory to the Driver

Accessories are keyed to driver class, and the two brands cross-reference to each other. Check the model on the tool plate first.

Common Questions

Do I need the guide tube adapter kit or just the adapter? The adapter alone must be run with a 1-1/4 in. x 6 in. large taper shank. The kit bundles that shank and a large tamper pad with the adapter, so it is the complete setup for an LPD-HD or PDR 95R.

Are Atlas Copco and Chicago Pneumatic post driver parts interchangeable? Across these matched pairs, yes — one guide adapter serves the LPD-T/RV and PDR 75, and one guide tube adapter serves the LPD-HD and PDR 95R. Nothing here crosses to Rhino tools; see post driving accessories for those.

What shank does the 80 lb class tooling use? A 1-1/4 in. x 6 in. large taper shank, the same interface behind breaker post, pipe and tamper driving tools.
