CZM -EK300LS Drilling Rig

Introducing the EK300LS Drilling Rig by CZM The EK300LS is a full cable crowd drilling rig mounted on a robust CAT352, designed to excel in a variety of drilling applications. Its long stroke rotary is particularly effective for operations that require precision and depth, such as cased Kelly bar drilling with segmented casing for Secant walls, Large Diameter Continuous Flight Auger (CFA), Displacement piles, Cased CFA with a double rotary for Secant walls, and large diameter single column Soil Mixing.

Product and Technical Information


The EK300LS is powered by the new Cat 352, featuring a fuel-efficient Tier 4 Final C13 ACERT engine. This powerful base is complemented by CAT Vision Link, which enables management to monitor machine operations and maintenance data online, ensuring optimal performance and efficiency.


The undercarriage of the EK300LS is a Caterpillar variable model VH5440/4900/900, reinforced with an H style frame that provides a stable and adaptable base for the rig’s operations.


A reinforced mast constructed from high resistance steel Weldox 900 gives the EK300LS the durability needed to withstand the demands of various drilling projects.

Main Winch:

The main winch system is designed with a special groove to enhance cable life through improved winding. It includes a press-roller and features two gears for a balance of high speed and substantial pulling force. The winch operates with automatic gear shifting for smooth, high-production drilling and includes an automatic down-the-hole winch stop. During crowd operations, the winch operates freely, with both hydraulic and mechanical brakes for safety. The cabin’s display of hydraulic pulling force measurements keeps the operator fully informed.


The EK300LS’s rotary is engineered for resilience, with two slewing bearings at the top and bottom, and a sturdy pinion and main gear. It houses three groups of Hydraulic Motor / Planetary Gears for exceptional torque and extended service life. The system is equipped with anti-cavitation, anti-shock, and a cooling system to ensure the hydraulic motors last longer. A power-shift feature allows for a high spin-off speed, facilitating efficient soil discharge. With three operational and spinoff speeds, the rotary is optimized for both high torque and rapid speeds. The operator can easily monitor torque via the hydraulic measurement display in the cabin.


The cab of the EK300LS is designed with the operator’s comfort and safety in mind, featuring an AM/FM Radio, air conditioning, heating, and ROPS certification with top protection. An LCD monitor connects to the engine and hydraulics computer, providing a comprehensive diagnostic system. The CZM Canbus System for Drilling Monitoring, complete with auto functions, further enhances drilling precision and efficiency.

The EK300LS drilling rig, with its CAM system and Displacement File capabilities, is a powerful and adaptable solution, offering unparalleled performance for foundational drilling projects that demand precision, power, and the flexibility to adapt to various site conditions.
