FORWARD GROUP presents its new development: Multifunctional Top Drive Drill Rig TDR-50 is unique equipment that allows drilling boreholes for various purposes in diameters from 108 to 1200mm and depth of 1500m by five different drilling methods. The engineers from Australia, Germany, Russia and China took part in the designing of this equipment.


  • Shallow oil and gas drilling
  • Water well drilling
  • Coal bed methane exploration
  • Rescue well drilling
  • Mine exploration drilling


  • Rotary drilling

-with direct circulation of mud

-with reverse circulation of mud

-with direct air blasting

-with reverse air blasting

  • Wire line core drilling
  • Auger drilling
  • Percussion core drilling (ram coring)
  • Down-The-Hole hammer DC and RC drilling

-with direct air blasting

-with reverse air blasting



  • The mast is equipped with 4 guide rails for the carrier of the drill head and a suspension for the feed device. The rig is also equipped with slipper system, in order to the mast slip, and the stroke is 3.65m, the mast can be reliably based on the ground.
  • The mast is constructed of high tensile steel and hydraulically elevated, mast lifting and lowering and degree of slope controlled by four (4) double acting hydraulic cylinders.
  • The rig can be set up the blowout preventer and other systems.

Top Drive Head

  • Hydraulic motor and gearbox could be adjusted for working on high speed and torque with high efficiency.
  • Top drive head suits for tricone bit, DTH hammer, PDC Drill bit and diamond bit which meets special demand of rotate speed and torque during work. The 4-shift gearbox using spur gear drive, oil bath lubrication.
  • The angle of rotate unit could be adjusted as needed, ranges from 0º(vertical) to 90º. The water connector can hold maximum pressure 35Mpa.

Electrical System

Generator and battery are driven by diesel engine and provide 24V direct-current power supply. All cables are protected with seal line. Furthermore, all circuits are equipped with short-circuited plunger.

Mud Line System

All mud lines on the TDR-50 Drilling Rig have 3" (76.2mm) diameter, in order to reduce friction losses to a minimum.

Additional Rig Components

TDR-50 Rig can be modified. All kinds of aggregates, required for different drilling methods, can be installed on the rig at customer request, or supplied as stand-by aggregates.
