2.4 Electronic system

The HDD adopts intelligent and CAN bus control technology. The meter shows clearly and easy to see.

The HDD shows the actual torque and push or pull force immediacy in the large and high showing size monitor automatic.

PLC control technology can detect the engine speed, the temperature of cooling water, the pressure of lubrication, the temperature of hydraulic oil, the pressure or stoppage of filter element, the position of carriage etc. It can also alarm to the operator in wrong condition.

The HDD travel safety at stepless speed regulation and controlled by wire cable.

The multi-speed control of rotation and push or pull make HDD be suitable to the complex geology.
