Product Features
GEMC’s drilling rig is well known for its featured high power, large output torque, axle pressure, flexible and drilling efficiency.
The drilling operation has been designed for drilling diameters of up to 3 m and drilling depths of maximum 112 m. It is driven by a Turb-boost dieselmotor offering great engine power and fuel-saving, not yet compromising the power supply.
Hydraulic system carries out through an advanced constant power load sensitive mode, holds a patented main valve distribution flow control system, ensuring the greatest rate of power utilization during working hours.
Full oil filtering returning and discharging circuits cooperating with high-end quality components gives a guarantee of stability and lasting while rig is working.
Built-in PLC control system, equipped with perfect CAN-BUS bus system, achieves the synchronized control among Mechanic, electrical and hydraulic system nicely.
Drilling tools for different purposes with different specifications such as long or short augers, generic-use drilling buckets and core barrels, etc., are equipped to satisfy construction requirements in different geological conditions.
Key components are equipped with world known famous brands items, like luxury driver’s operation room, multiple channel of cooling and heating air conditioner, which fully brings ergonomics into consideration, to ensure the drivers’ comfort and safety and thus reduce the work intense and improve the working efficiency at greatest extent.
If required, the rig can be disassembled into single parts. Thus, the rotary drilling rig can easily be transported throughout the world.
