JK593G Crawler Mounted Hydraulic DTH Drilling Rig 90-300mm Blasthole 4200Nm Torque Weichai Engine 30 Degree Grade

This JK593G crawler mounted hydraulic DTH drilling rig is one of the most versatile surface drill rigs in the JK range because its borehole diameter capability extends from 90 mm up to 300 mm. That unusually wide working range lets a single machine handle production blastholes, pre-splitting, and the large-diameter holes required for photovoltaic pile foundations and anchoring work. The rig produces up to 4200 Nm of rotation torque from a hydraulic rotary head driven by a Weichai 74 kW diesel engine, giving it the power to turn large hammers and maintain penetration in hard rock. With a grade ability of 30 degrees and a compact 7000 x 2400 x 2700 mm footprint, the JK593G moves easily around quarries, mines, and construction sites.

• 90-300mm Wide Hole Range: one rig covers production blasting, pre-split holes, and photovoltaic foundation drilling.
• 4200Nm Rotation Torque: powerful rotary head keeps large DTH hammers turning in hard, fractured ground.
• Weichai 74kW Engine: economical diesel power with dependable cold starting and low noise output.
• 30 Degree Grade Ability: strong climbing performance for hillside quarries and uneven terrain.
• 4138mm Feeding Stroke: long feed reduces rod changes and improves hole straightness.
• Dust Collector Ready: hydraulic dry or wet dust collection options keep the work environment compliant.

The JK593G is a favorite among contractors who take on mixed drilling work because it adapts to the job at hand. In quarries it drills production and pre-split holes; in mining it handles blastholes on bench faces; in renewable energy projects it drills the large-diameter holes used for photovoltaic pile foundations; and in civil engineering it performs anchoring and rock bolting work. The wide hole range also makes the rig suitable for water well drilling in softer formations when fitted with the appropriate hammer and compressor support. For rental fleets, the JK593G's flexibility means higher utilization across different project types.

Each JK593G is factory tested with a trial drilling run and full hydraulic pressure verification before packing. The rig is shipped in a 40ft open top container or flat rack with protective wrapping and secure lashing. Documentation includes the CE certificate, engine compliance papers, operation and maintenance manuals, and a hydraulic schematic set. Our team provides remote commissioning support, and spare parts for the Weichai engine and hydraulic components are available for rapid dispatch worldwide.
