GEMSA's MINERAL EXPLORATION DRILL RIGS
With extensive range of standard features and options !
Easy to use
Marmorok 90 is Gemsa’s DTH drill rig, is designed especially for marble quarries.
Drilling hole for marble wire cutting operations. It is based on proven and tried technology with simple design, which ensures continuous and uninterrupted operation ,even in the harshest conditions.
Fine control of drilling functions
Easy to set up the rig with its versatile and flexi-boom structure. It is capable of drilling good in straight, vertical as well as horizontal holes. Thanks for Gemsa’s creative solution for rotary head, it saves time by both way drill and increase productivity.
Drilling operation
Down the hole drilling. Hole diameter : 90 mm( 3 ½”) , depth 40m (130ft)
Most efficient power
DEUTZ 3-cylinder engine with inline turbocharging with an integrated oil cooling system. Best cold starting properties even under extreme conditions. The engines in the power range < 56 kW meets to the US EPA Tier 4 i. All parts for maintenance on one side of the engine, long oil change intervals and easy changing of engine fluids reduce the running costs and increase the availability of the machinery.An efficient injection system and optimized combustion ensure optimum engine performance at low consumption.
3x3 Wheel drive
An independent three-wheel drive system helps provide traction on rough terrain. Traction system is pilot control from backside platform and from drilling control panel.
Negative brake release for towing.
Easy to maintain and service.
All service points can be easily accessed and maintained.
Drill head - Rotation
GEMSA DW model drill head , cradlesupported with rollers
Driven by hydraulic torque motor.
Torque: 1.020Nm@ 100rpm
Feeding system
Negative brake planetary gearbox with hydraulic torque motor
Feeding stroke 2.500 mm (8,2ft)
Pull back force 25 kN - 2,5 tones @ 160 bar (5.620 lbf @ 2.321 psi)
More enviromental
Marmorok 90E is Gemsa’s DTH drill rig, is designed especially for marble quarries. Basic difference then Marmorok 90, 90 E can also work with electric power to reducing overall cost of ownership.
Drilling hole for marble wire cutting operations. Marmorok 90 E ensures continuous and uninterrupted operation ,even in the harshest conditions.
Non-stop operation !
Rig has 22kW ie3 electric motor and also Deutz US EPA Tier 4 i diesel engine. Both system can be used separately while drilling or travelling the rig. In general operation , diesel engine used while travelling rig , electric power used for positioning on drill site and drilling .
If something wrong with energy supply , then you can use diesel power to continue drilling.

All in one pack !
Marmorok NK 200 is Gemsa’s 3x3 wheel drive DTH drill rig, is designed especially for large scale marble quarries. Drilling hole for marble wire cutting operations.
The powerful Volvo Penta Stage V ( or Deutz Stage 3 ) diesel engine gives smooth and vibration-free operation with low noise level and emission, featured with high torque. Rig equipped with compact onboard air compressor.
Boost your productivity
Thanks to onboard compressor , it supply sufficient air under 15 bar
(217,5 psi ) while drilling. When comparing with low pressure (8-10 bar ) drill rigs , Marmorok NK 200 boost up productivity, save time and reduce the running costs .
Drilling operation
Rig capable of drilling straight, vertical and horizontal holes that enable the wire cutting operation.
Down the hole drilling. Hole diameter : 90 mm( 3 ½”) , depth 40m (130ft)
Onboard air compressor
Marmorok NK 200 is equipped with German brand onboard air compressor. It is a compact unit , an oil-injected screw compressor module that integrate the main parts of a compressor system and provide optimum operation reliability.
Working overpressure Max. 15 bar (217,5 psi) - 8,6m3/min (304 cfm)
Dust away while drilling
Gemsa hydraulic dust collector is used in rock drilling applications for improved productivity and improved working conditions with regards to dust. The filter cleaning function is carried out with reversed air.
Gemsa dust collector on board Marmorok drill rig start manufactured in Turkey on 1998 ( not a new technology ), continuously improved and built of high quality components to ensure long, safe and economical operation.
Easy to maintain and service.
