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: Attention problems of rotary drilling rig
- 1 remove the inspection cover near the base of the boom.2. Remove bolts, washers, lower cover and gasket.3, check the gasket, if there is obvious damage, should replace the gasket.4. Check the grease surface. Grease should be evenly distributed at the bottom of the tank.5. Check whether the grease is contaminated or discolored.6 grease should be replaced if the grease is contaminated or discolored by water.7. Lift the boom and transfer the upper structure to the 1/4 ring.8 repeat the procedure 7 1/4 cycles.
- Q: How to choose the drill bit of a spiral drill?
- During the operation of long auger, all the personnel present must wear safety helmet. In the construction process, according to the different geological conditions, choose different bit. The spiral rotary head of long auger rig adopts mud wall protection, which is suitable for cohesive soil, silt, sand, filling soil, crushed stone soil and weathered rock stratum above the water table.
- Q: What kind of stratum is suitable for rotary digging pile?
- Construction, according to different soil and geological conditions, according to the following provisions choose different drill bits:
- Q: What brand of rotary drill is good?
- Rotarydrilling not only buy quality, is to buy customer service, domestic rotary drill is Futian leiwo
- Q: What is the difference between punched pile and rotary pile?
- Punching pile is the impact of heavy hammer falling, the soil or rock to disperse or break, and then floating through the mud of these debris floating, and then pumping, the pile side of the soil compaction, I think it can be ignored. Punching piles are usually rock - in. They just break the rock and squeeze it out.
- Q: What brand of rotary drilling rig quality is better? How much? How long is it back?
- Rotary drilling rig is still a gap between domestic brands and foreign brands.
- Q: Rotary drilling rig how telescopic, I mean, what power so that it extends out of step by level, it extends out in a certain order?
- The drill pipe is connected to the main hoist by wire rope, and the main hoist relaxes or tightens the wire rope to lay down (stretch out) or lift the drill rod.From outside to inside, the drill pipe can be divided into the first section, the drill pipe, and the second section...First, the first section of the drill pipe to use, and then extended second knots, in turn out of the other section of the drill pipe, and finally stretched out the innermost section, contraction when from the innermost section of the contraction.According to the characteristics of civil engineering of rotary drilling rig needs to be improved.
- Q: The advantages and disadvantages of the rotary drilling rig and impact drilling machine used in the construction of bridge bored pile foundation
- According to the different geological and different methods of land weak cyclotron drilling sand layer rapidly, large pile diameter long friction pile most belong to this kind of formation so almost all of the cyclotron drill.
- Q: How many meters of construction hole pile can be used for a selection of tile drill from input to scrap, whether it is related to the diameter of hole pile
- Rotary excavation life with maintenance, operation, construction geology, pile diameter have a great relationship.Maintenance needless to say, a little common sense of all know.Operation is like adults with children, teach good, just do not learn well, it is waste.The quality of construction geology is also very critical. Just like the 60 year old man, called him one night and three young woman gas Wang ML, certainly fall apart!Pile diameter size and depth: for example, type 220 rotary excavation, the maximum theory is 2 meters 5, depth of 65 meters. But it's really hard to reach. The geology is good. 2 meters will be enough. If you really do 2 meters 5 of the pile, it is like a night can only do 3 times, I'm going to do 5 times, 7 times.
- Q: What's the market for small rotary drilling rigs? Do house foundations pile well?
- With the changes of the times, the small-sized rotary digging machines are more and more accepted by the market. But every industry has risks and needs to be cautious. A certain market awareness is needed, and blindness will be futile.
