ZT44

  • Horsepower 597 kW @ 2 100 rpm 800 HP @ 2,100 rpm
  • Compressor 38.5 CMM @ 34.5 bar 1,360 CFM @ 350 psi
  • Hole range 140 - 220 mm 5 1/2 - 8 1/2 in

Versatility, adaptability and performance for today's varying mining challenges

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.

  • Flexibility to drill in multiple applications on site

  • Core structures consistent with mining environment demands
  • Designed for 24/7 use for exceptional production

Features and benefits

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.

Compact design

The ZT44 blasthole drill adds exceptional versatility to your operation with a compact form that is designed for efficient drilling in tight spaces, while still providing the production capacity of larger machines.

Service accessibility

A wireless remote pendant, easy-access service walkways and unobstructed entry into the operator's enclosure help support lower mean time to repair (MTTR) and aides in machine serviceability.

Optimum heat mitigation

Heat exchange unit mitigates high thermal loads generated during operation. That makes the ZT44 capable of handling temperatures up to 131 F (50 C) in the harshest conditions, while also maintaining user-friendly serviceability.
