    KH5 Open hole drill car

    Safe and stable walking mechanism The center of gravity is low and the clearance from the ground is large, so that it can cross the rough road easily. Special wheel motor drive has strong climbing ability and low failure rate.

    1. Detailed information

    Product characteristics:


    Safe and stable walking mechanism

    The center of gravity is low and the clearance from the ground is large, so that it can cross the rough road easily. Special wheel motor drive has strong climbing ability and low failure rate.

    Advanced automatic leveling function of crawler and stop brake system not only make the drilling rig run stably, but also greatly reduce the impact of the ground on the drilling rig and ensure the driving safety.

    The unique anti stripping device has greatly improved the reliability of the drilling truck when walking.

    Vehicle-mounted diesel engine is adaptable to harsh environment. It can walk freely without external air compressor and is easy to move.


    Strong and reliable power

    The famous brand four cylinder diesel engine is used as power, with large power, small volume, small vibration and stable operation.


    New drill

    The optimized luffing mechanism and circular drilling arm have the advantages of novel structure, convenient adjustment, greatly increasing the drilling coverage and drilling low level holes.


    Powerful propulsion and slewing mechanism

    The new rotary mechanism is composed of a cycloid hydraulic motor with large torque and a planetary reducer, which provides a powerful torque reserve for the drilling rig and reduces the probability of sticking.

    The combination of hydraulic cylinder and pulley can produce 20KN lifting force and adjust the pressure regulating valve on the propulsion control valve to obtain the optimum thrust required under the working conditions.
