EK250

The EK250 from CZM Foundation Equipment is designed for high performance and versatility. This reliable drilling rig is mounted on a CAT336HHP Tier IV base, keeping the operation and maintenance extremely friendly and efficient.

The robust design of the EK250 rotary is due to the largest inner passage diameter of its class. This allows the EK250 to deliver higher drilling torque, the use of stronger Kelly Bars and extends the lifetime of main components. The big inner 

passage is a main feature of the unique, patented “Bottom Drive CFA” which allows the EK250 the versatility of fast, easy, economic conversion for various applications, like drilled shafts, CFA, and displacement pile.

The combination of hydraulic extended crawlers, centralized parallelogram and the mast made of a lightweight, high yield strength “Weldox” steel, afford the EK250 the safest stability.
