Mud mixing system: Can select 20CBM Mud Agitator
Onboard crane: 360°rotating straight arm telescopic jib crane, convenient for assembling and disassembling the drill pipe and lifting the drill tools and other drill tools, reduce the labor intensity, improve the working efficiency.
Monitoring and protection: The monitor has alarm system for up and down interlock, automatic high pressure protection, engine, hydraulic, filtering etc., which can efficiently protect the machine under safety condition.
Electrical system Mainly includes: startup of engine, flame-out of engine and checking, walking control, mud pump control, clamps control, clamp control, and pull push and rotating control to the power head, throttle control, the front and rear stop control of the power head. And also monitor the parameter of engine and hydraulic system and safety protection. It consists of left controlling platform, right controlling platform, auxiliary controlling platform, instrument box, travel control box, Television monitoring system. It adopts electro-hydraulic proportional control technology, realizing the stepless speed regulating. It also has manual operation for Emergency Back-up system
Engine and light alarm: this machine adopts 24V single wire system power supply, minus earth system. Double 12V storage battery series with the generator supply the electricity to the whole machine. The machine start electricity is provided by storage battery, after the machine is started on, the generator will supply the 24V DC to the whole machine and also charging the storage battery at the same time. Press down the STOP knob or emergency switch will let the engine stop work
Water thermometer: the engine water thermometer is used for indicating the engine coolant temperature, once the water temperature is over the set value, the water temperature alarm switch will close, when the Water temperature warning indicator light, stop the machine and check.
Oil-pressure gauge: it indicates the oil pressure of the engine. When the oil pressure is lower than the set value, the oil pressure alarm switch will close, oil pressure indicator lights,( the light will light even the engine stopped, it is the normal condition), and stop the machine and check
