2023 Komatsu Blasthole drills ZT44

The ZT44 is a down-the-hole surface drill rig designed for mining-duty applications. It offers high reliability and production with purpose-built structures, a high horsepower engine and large capacity dual-setting compressor that adapts to varying rock hardness conditions. The ZT44 is a versatile machine, used for pre-split, production, auxiliary and other demanding needs.

Features may include:

Dual-pressure air compressor

With both high- and low-pressure drill settings, this compressor can adjust to changing drilling conditions, allowing for optimal performance up to 8.5-inch hammer. This largest compressor in its class can handle challenging elevations where production often drops off.

High tractive force and more

Powerful tractive force and an independent oscillating undercarriage deliver maneuverability on uneven grades and the ability to perform in various settings. That gives your operation more flexibility to determine the optimal use of your machine.

Four infrared night vision cameras

Through the use of a video system, your team will have excellent operational awareness around the machine. Plus, bright night-time illumination with LED lighting offers outstanding visibility for operators.
