Kaishan KD45E Integrated Surface Crawler DTH Drill Rig (90–135 mm)

• Enhanced 176 kW Powertrain & 18 Bar Air End: Driven by a heavy-duty Yuchai YCA07240 engine (176 kW vs. 162 kW on KD40E), providing superior power margins for simultaneous full-pressure 18 bar hole flushing and rapid penetration in 90–135 mm boreholes.
• 2,500 N·m High-Torque Performance: The upgraded rotary drive delivers 2,500 N·m of torque, enabling aggressive rock cutting through hard granite, basalt, and fractured limestone without bit jamming.
• Expanded Dual-Hinge Positioning Versatility: With its innovative two-hinge carriage swing design, 130° beam tilt, and 3,590 mm feed advance length, the KD45E covers a wider drilling pattern per bench setup, significantly boosting daily drilled meterage.

Q: What are the primary performance advantages of the KD45E compared to the KD40E?

A: The KD45E upgrades diesel engine output to 176 kW (versus 162 kW on KD40E), increases maximum rotary torque to 2,500 N·m (versus 2,000 N·m), expands borehole diameter up to 135 mm (versus 127 mm), extends one-time advance length to 3,590 mm (versus 3,000 mm), and features an advanced dual-hinge carriage swing mechanism for superior multi-angle boom positioning flexibility.

Q: Does the KD45E require an external auxiliary air compressor?

A: No. The KD45E is an all-in-one integrated crawler drill rig with an onboard 18-bar, two-stage screw air compressor (15 m³/min) driven directly by its 176 kW Yuchai diesel engine, operating autonomously with no trailing air hoses.

Q: What drill rods and DTH hammers are compatible with the KD45E?

A: The KD45E is compatible with both 3-inch and 4-inch high-pressure DTH hammers and supports Φ64 mm or Φ76 mm × 3,000 mm friction-welded drill pipes, providing exceptional versatility across various quarry hole diameters from 90 mm to 135 mm.
