4.drillin
Product name: mechanical drilling rigs ZJ50/3150L
Features:
1. various drive modes including "diesel engine+hydraulic coupling transmission+chain comound" "diesel engine+reducing gear box+narrow V belt compunt" are available for option. The power is reasonable distributed for higher efficiency.
2. Eityher inner or outer speed change is optiaonal for draw works. speed change is easy and fast by remote pheumatic control.Main brake is either band brake or hydraulic disc brake. Electric magnetic eddy current brake for auxiliary brake.
3. For drilling rig over 4000m in drilling depth, rig foloor is in two levels which is "front high rear lower" power and transmission system are installed on the rear low level and the rig power is transmitted to drive rotary table and catworks located on drill floor through bevel gear reducer and universal shaft.
4. Module designed, advanced technology, easy for assemble and disassembly.
5. with bailing drum, mechanical friciton cathead and rotray table drive device.
6. Independent driller cabin is on the user's requirements.
7. Independent automatic drilling system could be equipped as the cllinet's requirements.
8. Tope drive drilling system could be supplied.
