Benefits & Features
1.Efficient Rock Breaking
The maximum hardness of rock which can be cut at time of joint development is f11;
We can design, process and manufacture cutting teeth on our own to eliminate the need for import;
Three-stage vibration damping technique: patented cutting teeth arrangement, flexible transmission and differential pressure damping structure are used to systematically solve the problem of impact damage by cutting vibration on the overall machine and critical and important parts.
2.Efficient Dust Removal
Integrated dust removal system innovated in the industry: long-pressure short air ventilation curtain type dust removal system with a total dust removal efficiency of ≥97%.
On-board mining-purpose dust-proof suction system: fundamentally solve the problem of harm to health of staff by construction dust and powder.
3.Centralized Lubrication
The roadheader employs centralized lubrication technique so that lubrication is easy greatly saving oil injection time and reducing work load of underground workers.
- Q: Various types of rotary digging drill rod head size
- Because the rotary digging into the sea China earlier, there is no uniform B by national standard, but the host plant is basically the same, but the difference is mainly divided into two types of schools: as schools, using standard rotary drilling chassis, the stability is good; 31 schools, using the general excavator chassis, stability has been lacking, but saves cost
- Q: The Montreal rotary drilling mud powder special effect is good
- Use the Montreal mud powder we built in the West Zhengzhou North Sanhuan Henan province Forest Park interchange site every day a rig can pile 3 to 4, if the bentonite for most 2 really benefit.
- Q: Why not use rotary drilling rig instead of manual digging pile?
- 1, can not find the right rig.2, on a drilling rig drilling too difficult.3, have luck, want to save money.
- Q: How high are auger rigs and impact drills?
- Rotary drilling rig upright, 20 meters to 28 meters, the more high, about 3.5 meters high transport status.
- Q: How many litres of oil are usually consumed per hour in a rotary drilling rig?
- This is not sure, depends on what type, and when the work is not full power work.
- Q: How many piles per day can the bored pile foundation be 400mm and the pile is 25 meters long?
- The pile can be divided into two kinds of bored pile and dug pile according to the way of hole formation. The digging pile is dug by hand, and the bored pile is made of mechanical hole, according to the mechanical difference. Bored piles are made of underwater concrete, and bored piles can be divided into the following types.
- Q: How much oil is used in the 31 rotary drilling rig?
- Check whether the gear oil quantity of the reducer is adequate and the oil quality is normal;
- Q: The advantages and disadvantages of the rotary drilling rig and impact drilling machine used in the construction of bridge bored pile foundation
- Most of the hard rock formations have little pile diameter and are mostly end bearing piles. Most of them are made of impact drilling. Some of them are excavated by hand, and the small hole is short. The majority of bridge piles are impacted. Encountered complex formations, the pile length is less than 40 meters, the most reliable is the use of impact drilling. A look at geology, two to see the quality, or positive and negative cycle drilling, good quality of the hole, steel dragon protection layer can guarantee
- Q: What are the hidden dangers during the construction stage of rotary drilling rig?
- Hole air quality, hole wall quality, water gushing, quicksand and other geological conditions, orifice protection, safety protection inside and outside the personnel hole, mechanical equipment operation conditions, probably on these, one, a good grasp on the fine.
- Q: What kind of hydraulic oil is used in XCMG XR220 rotary drilling rig?
- Summer fever is normal, at about 50-60 degrees on the line, the use of hydraulic oil is no problem, check the system has no leakage, and if there is leakage, and then a good hydraulic oil will also be hot.
