330HP form Jinan plus 295kW from Yuchai, 25 tons total, footprint 9600×2600×4000mm—delivery typically 8-10 weeks once order's confirmed.
It's a rotary rig with a diamond bit, basically built for deep holes in hard ground, and the four-connected pump system (63+63+63+25) keeps hydraulic presure stable even when you're pushing that 11000 torque through tough formations.
Standard drilling depth runs 200-350m, but with the pneumatic setup you can go to 500m or so—though we usually stock the standard configuration, so confirm lead time if you need the deeper option. The 250 hydraulic-driven mud pump handles variable soil conditions pretty well, but it's not ideal for loose sand or highly fractured rock where circulation loss gets ugly.
Lifting capasity sits at 1.5T on the hoist and 26T during drilling—most buyers go with crawler chassis for uneven sites, as it's easier to maneuver than truck-mounted alternatives.
ISO 9001:2000 certified, but don't expect perfect paperwork —COAs are typically available within 2-3 days, not instantly. Also, the rotating motor (490+490) gives you tighter tolerance than older models for directional control.
The 500m depth is achieved when you switch to the pneumatic drilling system. Standard rotary drilling goes 200-350m, but with pneumatic assist, you can push that full 500m. The diamond bit handles that just fine.
Both engines are included—the 330HP Jinan Heavy Duty works alongside the 295kW Yuchai to give you that combined power for deep drilling. It's a dual-engine setup, not an either/or.
The machine is ISO 9001:2000 certified, so you'll get a certificate of conformance with that standard. We can also provide a material test report for the diamond bit and hydraulic components if you need it for your project.
Yes, we can customize the drill diameter within the 178-325mm range, and adjust the hoist lifting capacity up from 1.5T if your project needs more. Just let us know your specs, and we'll tweak the hydraulic system accordingly.
MOQ is 1 unit. Lead time is usually 45-60 days, depending on customization. We can ship it FOB from our port, and we'll include the diamond bit and AC motor system as standard.
