Discover the EK160USM by CZM The EK160USM is a specialized foundation drilling machine from CZM, expertly crafted for constructing Transmission Lines. It features an innovative parallelogram design with tilt cylinders that face downwards, enabling it to operate in areas with very low overhead clearance, as low as 20 feet. The rotary of the EK160USM is engineered with a large inner passage, suitable for a robust 6 element kelly bar that can drill to depths of 65 feet while maintaining full torque. For enhanced convenience, the EK160USM includes a self-erecting counterweight, simplifying the setup and breakdown process.

Product and Technical Information


The EK160USM is powered by the new Cat 330 Next Gen with a fuel-efficient Tier 4 Final C7.1 ACERT engine. It comes equipped with CAT Vision Link, allowing for online management monitoring of machine operations and maintenance data.



The machine boasts a Caterpillar variable undercarriage VH4400/4300/700, with a reinforced frame and H style variable undercarriage for stability and adaptability.



The mast is constructed from high resistance steel Weldox 700, ensuring strength and durability for the demanding tasks of foundation drilling.


Main Winch:

The main winch is designed with a special groove to enhance cable winding and extend cable life. It includes a press-roller and features two gears to balance high speed and high pulling force. The winch operates with automatic gear shifting for efficient, high-production operation and includes an automatic down-the-hole winch stop. During crowd operations, the winch operates freely, supported by both hydraulic and mechanical brakes. Pulling force is hydraulically measured and displayed in the cabin for the operator’s convenience.



The rotary’s robust design includes two slewing bearings, a sturdy pinion, and main gear. It is equipped with two groups of Hydraulic Motor / Planetary Gears for exceptional torque and extended service life. The anti-cavitation, anti-shock, and cooling systems ensure the hydraulic motors’ longevity. With a power-shift function for high spin-off speed (120rpm) and three operational speeds and spinoff speeds, the rotary is optimized for high torque and high speeds. Automatic gear shifting ensures seamless operation, and the exchangeable keys are bolted for easy maintenance. Torque is hydraulically measured and displayed in the cabin for the operator.



The operator’s cab is designed for comfort and safety, featuring an AM/FM Radio, air conditioning, heating, and ROPS cab with top protection. An LCD monitor provides access to the engine and hydraulics computer, complete with a diagnostic system. The CZM Canbus System for Drilling Monitoring includes auto functions to enhance drilling operations.

The EK160USM, with its Ultra Short Mast, is a compact yet powerful drilling solution from CZM, engineered to deliver high performance and efficiency for foundation work, particularly in environments with height restrictions.
