~Design advantages
1. NYC-400ZYII truck mounted drilling rig is a kind of rotary drilling equipment.
2. The drilling rig is equipped with SINOTRUK(drive form:6*4) truck crane chassis, and the transfer case, main drive, gearbox, dual-winch, slurry pump, rotary table, drill tower and steel wire feeding system are all mounted on the chassis.
3. Drilling method
A standard NYC-400ZYII truck mounted drilling rig adopts directional circulation drilling method. Equipped with BW850/2A slurry pump, it utilizes slurry as the drilling fluid, and finally achieves direct circulation drilling with the help of the high pressure plunger pump.
If equipped with proper drilling tools, the drilling machine can also achieve other drilling methods.
4. Power system
NYC-400ZYII truck mounted drilling rigs are equipped with automotive engines, and also additionally equipped with transfer case and hydraulic system. Hence, the truck and the drilling mechanism can work simultaneously.
5. Three-phase AC generating set provides the vehicle mounted drilling machine with convenience for welding operation and equipment maintenance at night.
6. NYC-400ZYII is equipped with dual-winch and drill tower pulley block, etc. which functions to increase the drilling pressure and assists the water well drilling rig in drilling into mud rock, and bed rock, etc. This design is very effective in improving drilling efficiency.
7. Driving system
This truck mounted drilling rig is primarily mechanical driven. The drill tower and the four levelling legs are hydraulically controlled. The two mechanical legs, transfer case and slurry pump's valves are pneumatically controlled.
Applications
The rotary table of this truck mounted drilling rig comes with large torque and as a result the drill equipment makes a hole quickly. Currently, our drilling rig has found applications in water conservation projects, the drilling of industrial deep well, conventional water well and geothermal well, etc., and national defense fields, to name a few. It is applicable for drilling into clay, sand, bed rock, basalt strata, and more.
Configuration options
1. According to customers' requirements, our truck mounted drilling rig can be equipped with air compressors from different manufacturers, like America's SULLAIR, Sweden's ATLAS COPCO, China's KaiShan Group and HongWuHuan Group. Thus, the equipment can achieve pneumatic down-the-hole hammer drilling.
2. If equipped with air water separator, dual-wall drill pipe and other related devices, the rotary drilling rig is also able to achieve reverse circulation drilling.
3. If equipped with drill tools like hydraulic down-the-hole hammer, and 850/2A mud pump, the vehicle mounted drilling equipment can realize hydraulic DTH drilling.
