Directional Drilling Machine 400 tons

Additional Details

Customers can avail from us a high performing array of Directional Drilling Machine GD4000 – LL. These are technologically sound machines that are high on efficiency and requires minimum maintenance. The main power is two sets 373 kw/1800 rpm Dongfeng Cummins engines for supporting the rotation of the main axle and pull & push of the power head. It makes these machines to work separately according to the working conditions.

Main Equipment

    Cummins 392Kw/2100 rpm Two sets Cummins 132kw/2200 rpm 1 set
    The Hydraulic Pump: American Sauer Company 90 series, flow adjustable close-circuit piston pump with output 130ml six sets used for the rotation of main axle and pulling and pushing of power head
    Geard pump two sets for clamp and crane assistance
    The Main Motor: Original imported from American Sauer Company, adjustable piston motor with output 107.5ml/r using for the pushing and pulling of rotary driving head 10 sets
    The loop flushing valve produced by Italy SAM Company centralized with motor, which makes it less room and fewer pipelines
    Speed reducer from Italian Dinamil Oil Spa or German KPM using for the push & pull and rotation 13 sets
    Clutch with our Self-owned intellectual property rights for pulling and pushing of driver head 10 sets
    Two sets of 530kw, 530Kw, i=0.8125(growth rate = 1.2307) transmission boxes are imported from Germany
    The Hydraulic Pipes are from American EATON Company
    Original high pressure steel rings and rubber pipes are imported from Italy
    High wear- resisting, high anti-attack alloy steel rack and pinion

 Main Performance Characteristics:

    If two engines work together, they could achieve the maximum torque, the maximum rotary speed, the maximum pulling and pushing force
    The rotating and pushing and pulling of rotary driving head adopt the close circuit, which could protect the system, extend the life and use less fuel. Other assistant mechanism adopt open circuit
    Ten suits of pulling and pushing motors operate by manual cluthes and could be interchanged, which prolongs the life of motor and speed reducer
    The main body and power station adopt caterpillar type , one set of 132KW/2200rPM Cummins diesel engine, which can walk for long distance (3000m/h)
    The caterpillar can be fixed and removed at the working place, reducing the transportation weight
    It eliminates the load and avoids leak of mud
    The movable beam is convenient to carry up and down, to transport and adjust entry angle
    Clamp with two cylinders each side, front and back clippers could be apart ant the clamp could move within the whole distance
    It is controlled by wire. The operate position is at the back of power head, which has large room and easy to operate
    The rotation and pushing and pulling speed could be entire pole less proportion linearity speed regulate
    Working pressure within the range could be remote controlled, which could be adjusted the torque and push and pull force
    It is equipped with mud pressure release mechanism, the system is reliable by show the pressure of mud pump, which is the unique design
    The movable main axle makes unload the drill rod conveniently
