CZM – LR125 Drilling Rig

The LR125 is the more compact sibling of the LR160, offering a lighter construction while still providing formidable drilling capabilities. Mounted on a CAT 340 Next Gen with lighter tracks, the LR125 features a specially designed boom with two lift cylinders, enhancing its torque and crowd force when using interlocking Kelly bars, making it highly efficient for drilling in rock and hard soil. Round Friction bars are also available to boost productivity in softer soil conditions. Its long reach configuration is ideal for projects such as constructing sound barrier walls, installing transmission lines and utilities, drilling on steep slopes, and accessing holes in challenging locations.

Product and Technical Information

The LR125 is equipped with the new Cat 340 Next Gen, powered by a fuel-efficient Tier 4 Final C9.1 ACERT engine. This base is further enhanced by CAT Vision Link, which allows for online monitoring of machine operations and maintenance data, ensuring peak performance and efficiency.


The undercarriage of the LR125 is a Caterpillar variable model VH4600/4450/720, 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 700 gives the LR125 the strength needed to withstand the demands of various drilling projects.

Main Winch:

The main winch system features a special groove for improved cable winding and extended cable life. It includes a press-roller and offers two gears for a balance of high speed and significant 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 LR125’s rotary is built for durability, with two slewing bearings at the top and bottom, and a robust pinion and main gear. It houses two groups of Hydraulic Motor / Planetary Gears for exceptional torque and extended service life. The system includes anti-cavitation, anti-shock, and a cooling system to prolong the life of the hydraulic motors. A power-shift feature allows for a high spin-off speed of 120rpm, 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 LR125 is designed for operator comfort and safety, 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, enhances drilling precision and efficiency.

The LR125 drilling rig, with its Standard Mast and Long Mast options, is a versatile and powerful solution, offering unparalleled performance for foundational drilling projects that require precision, power, and the ability to adapt to various site conditions.
