DTH Rotation Unit from HARDAB
All parts of a HARDAB down-the-hole rotation unit or top drive as its also called are exclusively manufactured by HARDAB. Because we make our rotation units ourselves from start to finished product, we have a deep knowledge of the product to quickly help when breakdowns happen.
HARDABs latest rotation unit has been in us for almost 10 years with no total breakdown recorded to date.
Power Torque: With the click of a button, you get twice the torque power for when you need to connect the pipes just a little tighter. On Manually Controlled rigs enabling the function is done with the press of a button on the rotation joystick. On Fully-Radio Controlled rigs enabling the function is done with the press of a button on the side of the radio control transmitter and using the rotation joystick. All rigs can enable the function for a longer duration with a button on the iQDrill screen.

Equipped with two load-sensing variable axial piston pumps by Danfoss and a dedicated gear pump from our own Made in Europe HARDAB Hydraulics brand dedicated for the pull-up function.
Nothing is as damaging to operators as breakdowns when you need the machine the most. To hydraulics, nothing is more damaging than dirt, water, and unwanted particles. That’s why all our drilling rigs have seven (7) hydraulic filters to protect critical components and prolong the expected machine life.
- One return filter dedicated to the hydraulic welding machine and optional equipment (on top of the tank)
Protects the hydraulic tank from contamination from the hydraulic motor at the welding machine.
- One water-absorbing return hydraulic filter (on top of the tank).
The filter element has a special water-absorbing coating. Water can cavitate on hydraulic spools and make rust inside adapters.
- Two LS-filters
To protect the pump load-sensing regulators
- One feed pump pressure filter.
Filters oil for feed valve and one of two side function valves.
- One rotation pump pressure filter.
Filters oil for rotation valves and one of two side function valves.
- One pull-up pump pressure filter
Filters oil from the gear pump to protect the feed valve
- Three air breather filters (rotation unit, hydraulic tank, diesel tank)
Protects the hydraulic system tank, the grease inside the rotation unit, and the diesel inside the diesel tank from condensation water.
- Optional filter for optional equipment that requires pre-filtering as well as hydraulically driven engine fans (only John Deere 4045).
To protect option valves.
Because HARDAB only chooses high-quality filters you consistently get maximum oil cleanliness in your machine. HARDAB users who change filters according to the maintenance scheme enjoy fewer hydraulic faults than any other machines.
HARDAB uses a long-life PVC hard-coated hydraulic hose made in the EU that has excellent abrasion resistance. Where needed we add an additional HD-PE plastic protection spiral for even more hose protection.
Hydraulic servicing is easy to reach ground level.
The hydraulic system is proven in the field for many years and is easy to faulty search. Many hydraulic faults are solved by the operator with the help of HARDAB technicians by phone.
We mount hydraulic pressure sensors for even simpler hydraulic faulty searching with the iQDrill system over the air with our service technicians or by technicians at the machine.
Hydraulic Water Pump and Welding Machine
HARDAB drilling rigs come equipped with a hydraulic water pump and a hydraulic welding machine as standard. The water pump is located in a heated cabinet. Optionally a larger hydraulic water pump may be purchased.
Highly Durable Frame
Your bottom line is improved by the highly durable frame that makes up the rig. Built to last and to be the better option in the most challenging conditions. We build our rigs on steel square tubes carefully selected for their elastic tendencies, which makes cracks less prone. All welding on a HARDAB drilling rig is made according to the highest standard.
HARDAB designs and manufactures our own undercarriage. Every component is engineered for lasting durability, including rubber/steel or steel tracks, forged steel idlers, and strong drive motors.
The sloped track frame prevents mud and debris accumulation, helping reduce the risk of track damage due to the build-up of debris.
Our use of mild steel for the frame, derrick, and other components keeps field repairs simple. We do not cover up the rig in unnecessary thin metal plates that make repairs harder and more time-consuming than they should be.
All frame components are painted with a two-component, high-gloss polyurethane paint to form a durable, easy-to-clean, and non-chalking topcoat with outstanding gloss and color retention. Our own paint color, HARDAB Yellow was developed jointly by HARDAB and our paint provider to look good during the harshest drilling operations.
We believe in our product so; we give a comprehensive warranty against defects. 12 months or 1500 machine hours whichever occurs first.
Centralized grease points and easy access to other maintenance items including the battery, oil filter, air cleaner, fuel filter, and other components simplify servicing and reduce time spent on regular maintenance procedures.
Hydraulic fluid level checks are made easier with a sight gauge.
Electrical connectors are sealed to lock out dust and moisture. Harnesses are covered for protection. Wires are color and number coded for easy diagnosis and repair.
Diagnostics are straightforward with our iQDrill System. HARDAB Service Technicians offer both over-the-air 4G diagnostics from our offices in Sweden or On-Site Diagnostics at your site with the closest HARDAB service technicians.
Many diagnostic points are available to the customer through the iQDrill touchscreen which means the operator can identify the faulty part before contacting HARDAB.

Benefits of a 6-meter rig
Using longer drill pipes in DTH (down-the-hole) drilling and Reverse Circulation drilling can provide several benefits that can help to improve efficiency, reduce costs, and increase productivity. Some of the key benefits of using longer drill pipes include:
- Improved efficiency: Using longer drill pipes can increase the efficiency of the drilling process, as you can drill more footage with each drill pipe, reducing the number of connections that need to be made thus saving time and improving productivity.
- Reduced fuel consumption: The longer drill pipes and the fewer connections allow the compressor to operate at a reduced work rate, which helps to lower fuel consumption and operating costs.
- Pipe handling system: Our pipe handling system allows the operator to load and unload drill pipes more efficiently, increasing the overall productivity of your operations.
Manual Control or Full Radio Control
All HARDAB rigs are available with a classic control panel or easy-to-use full radio control.
The HARDAB Manual Control Panel is designed to be user-friendly and efficient, with all necessary machine functions conveniently located in one place. The control panel is equipped with two high-quality German-made control valves and two Parker joysticks for feed and rotation with integrated buttons for Power Torque and Turbo Feed (only available for 6-meter models).
Full Radio Control
By using a HARDAB drilling rig with full radio control and our patented rod handling system, the operator’s safety and comfort are significantly enhanced.
- The radio control has as many proportional functions as possible, including rotation, feed, support legs, mast, winch, and pipe handling system.
- Toggle switches are used to activate or deactivate only certain functions, such as the welding machine, the water pump, and the breakout key cylinders.
- Having up to 20 hours of battery time allows you to be productive throughout the entire day.
