PI RC/RAB Top Drive

The PI rotation unit is a simple, medium-duty, top drive that can be used for RAB (rotary air blast) or reverse circulation drilling. The PI features a chain and sprocket drive design, floating keyed spindle and a top connection for an optional RAB swivel or combination RC swivel. The PI top drive is used on the Prospector I RC drill. It is also the standard for larger diameter RC conversion and multi-purpose drilling packages. The unit is ideal for larger diameter RC and RAB drilling to depths up to 300+ meters. Floating spindle connection options include 2-7/8” Reconn, 4” and 4.5” Remet, and Metzke threads. The PI top drive can be configured with a high-speed coring option for multi-purpose applications. It can also be configured with a planetary and piston motor for higher torque auger drilling requirements. The simple, easy to maintain design makes the PI top drive ideal for exploration air rotary drilling.
