Description of 280M Cheap Water Well Drilling Rig:
280M Cheap Water Well Drilling Rig is widely used for water well
drilling, geothermal air-conditioning venture and other boreholes,
especially relevant to mountain area and rock formation water
engineering. Much higher environment friendly than the traditional
mud rotary drill rigs, creating the widespread economic benefit for
users. Especially remedy problems to drill hard rocks that the
usual rotary drilling rig meet and it should work with air
compressor. When drill soft underground formation, it is OK to use
mud rotary drilling, and there is mud drilling swivel system.
Features of 280M Cheap Water Well Drilling Rig:
1. Guangxi Yuchai diesel engine( cummins engine for option), strong
power;
2. The patented design of the composite boom, double cylinder lift,
long trip, high tonnage
3. Each rig is equipped with stoppers to raise the big arm to
protect the safety of the cylinder.
4. Rig chassis: professional excavator chassis, durable, large
bearing capacity, chain width, hard road damage;
5. Parallel transmission design, separate oil pump, sufficient
power supply, reasonable distribution, unique design of hydraulic
system
6. The traveling motor is equipped with a gear box, which is
durable and has a long service life.
7. Dustfall device: Effectively reduce dust pollution damage,
aiming at pit and tunnel construction
8. Fast distribution valve: speed three gear up to 70 rpm, basic
dual-use water vapor function
