Key units of hydraulic system use Caterpillar hydraulic systems main control circuit and pilot operated control circuit , with advanced load feedback technology , which made the flow distribute every units of the system according to need , in order to achieve the operation have the advantages of flexibility , safety , conformability and exact .
The hydraulic system is radiating independently.
The pump , motor , valve , oil tube and pipe coupling are chosen from all first class parts which ensure high stability . Every units designed to high pressure-resistant ( The max pressure can reach 35mpacan work in high-powered and full load.
The electronic control system applies the DC24V direct current , and PLC monitor the working condition of every unit such as starting-up and extinguishing a fire of engine , the upper rotation angle of mast , safety alarm , the drilling depth , and the failure.
The main parts of electronic control system are high quality and adopt advanced electronic leveling device which can switch freely between automatic state and manual state . This device monitor and control the mast to keep vertically during operation . The mast is auto controlled and monitored by the advanced manual and auto switch electronic balance device to keep its vertically , which could guarantee the vertical requirements of the piling hole effectively and achieve the humanization layout of the control and friendly Human-machine Interaction.
The whole machine has proper layout to reduce counterweight : the motor , hydraulic oil tank , fuel tank and the master valve are located at the back of the slewing unit , the motor and all kinds of valves are cover by a hood , elegant appearance .
