2 SAVANNAH GEORGIA USA THE COMPANY CZM has over 40 years of foundation equipment manufacturing experience with a wide range of models for multiple applications: drilled shafts, CFA, driven piles with hydraulic hammers, secant piles, micro piles, and anchoring, among others. CZM Foundation Equipment s USA manufacturing facility is located in Savannah, Georgia. CZM Foundation Equipment has designed their models with the after sales being priority. Quality and service are the main ingredients to a quality machine, this is one of the direct reasons CZM uses Caterpillar as a base, the Caterpillar bases are not only operator and maintenance friendly but by using Caterpillar it enables the customer access to the large and already nationally established Caterpillar Network. CZM is the world s largest manufacturer of CFA drilling rigs, featuring the revolutionary torque mechanism Bottom Drive CFA, an internationally recognized CZM patent. 02 CZM FOUNDATION EQUIPMENT

4 APPLICATION The EK250 from CZM has been designed for high performance and versatility. It is a reliable drilling rig mounted on a CAT336HHP TIER IV base, keeping the operation and maintenance extremely friendly and effi cient. The robust design of the EK250 rotary, is due to the largest inner passage diameter of its class. This allows this model to deliver higher drilling torque, the use of stronger Kelly bars and longer life time of main components. The big inner passage is a main feature of the unique CZM s patented mechanism Bottom Drive CFA which allows this drilling rig the versatility of fast, easy and economic conversion for different applications such as drilled shafts, CFA and displacement pile. The combination of hydraulic extended crawlers, centralized parallelogram and the mast made of a light weight / high yield strength weldox steel enable this model the safest stability.
