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:For different geological conditions, how to choose rotary drilling, rotary drilling, impact drilling?
- Rotary excavation is often used in the excavation of cohesive and sandy soil layers, but the efficiency is relatively high. But for rock foundation excavation, the requirements for rotary excavation equipment, especially the requirements of drilling bit and drilling rig, are very large.
- Q:Xr220a rotary drilling machine drilling 2 meters hole can reach 80 meters, its maximum drilling depth is 80 meters, the maximum aperture is 2 meters.
- Attention is conditional, and there is the maximum drilling depth is 79 meters, there are 1 meters gap, if you count the drill bucket distance, barely enough.
- Q:How can the drilling rod of rotary drilling rig be telescopic?
- It extends in the first order, the next second, and then the third, the last, the fourth, and the fifth. During drilling, it is stretched by gravity and bit by bit with the drilling depth. Rotary drilling rig in the multi-functional areas to improve, and it is not necessary to complex conversion can be converted to another device, it is worth studying.
- Q:What are the hidden dangers during the construction stage of rotary drilling rig?
- The rotary drilling cast-in-place pile is also divided into dry hole, soil sampling rotary pile and reverse and reverse rotation pile
- Q:How much oil is used in the 31 rotary drilling rig?
- Check whether the fuel tank is adequate and the oil is normal;
- Q:Rotary drilling rig application
- The main purpose of rotary drilling rig is to:Bored pile foundation engineering rotary drilling.
- Q:How heavy is the 250 auger rig?
- There is a SR360 rotary rig, the largest 200 ton rig in Asia
- Q:What brand of rotary drill is good?
- Abroad, Bauer, I used the Futian leiwo, is awesome, Carter chassis, three motor reducer, power head multi speed control, embedding ability of super strong, often machine is an open day.
- Q:What drills are used to drill the hard layer of the rotary drilling machine?
- I want to know how thick and big the pebbles are in you. Strong, weak, weathered, with double door fishing sand drill (pick teeth) can
- Q:What are the advantages and disadvantages of the construction of the bored pile with auger and rotary drilling? Another auger can drill 1800 diameter piles?
- Screw drill to see torque, I use 10T-m. You might be talking about a small spiral drill. In the early 90s, I personally did 3.5 meters of pile, the use is: the first with a diameter of 2.8 meters of drill, and then use the diameter of 3.5 meters drill hole reaming, so completed the diameter of 3.5 meters of pile foundation.As for the rotary drilling machine, we can not rule out the possibility of digging deep, but the cost of equipment and on-site operations are cost-effective. Only the builder knows it; and when it comes to rock formations, rig it.
