Machine Advantages
The RCZ - 18J drilling rig improves the durability of the drilling tool with its durable 104M impactor and double buffer device, while the double triangular floating support arm design ensures the accuracy of hydraulic control. The feed system uses high - strength heavy - duty aluminum alloy beams and is equipped with stainless steel and wear - resistant gaskets to extend service life. The automatic hydraulic impactor control system realizes intelligent management of the impact process, including automatic casing, lubrication, water loss protection and feed control, effectively preventing blockage. The rig also features two - speed travel, automatic deceleration and enhanced torque output to prevent the engine from overloading when climbing hills. The chassis is designed as a strong, articulated heavy - duty chassis with four - wheel drive, a four - cylinder diesel engine and hydraulic jacks to ensure stable positioning. The dual - circuit pedal brake system provides emergency parking control to ensure operational safety. Other features including a height - adjustable safety canopy, cable drum, electric piston compressor, electric water booster pump and work lights further complete the rig's capabilities.
