The trolley carries a 6000 kgf load capacity on a four-wheel, two-axle chassis with air-operated drum brakes, allowing the unit to move between sites without a dedicated truck mount. The feed system delivers 4700 kgf pull-back and 2800 kgf pull-down, while the rotary head runs at 1 to 100 rpm with 215 kg-m torque.
A 600 lpm mud pump and a 600 cfm, 200 psi air compressor support flushing during operation, and four hydraulic stabilizer jacks hold the rig steady on uneven ground throughout drilling.
