MGJ-50L Crawler Drill Rig for Anchoring andJet-grouting

Applications：

MGJ-50L crawler drill rig for anchoringand jet-grouting is a type of integration of crawler, mud pump and controlpanel based on original MGJ-50 drill rig for anchoring and jet-grouting. Itfeatures long feed stroke, large capacity, easy to operate and move etc. It isbetter idea anchoring drill rig for anchoring bar, consolidating andstrengthening engineering and all other engineering geological drilling.Thedrilling rig is mainly used in soil and rock anchoring, consolidation of roadbase, dam base and retaining wall, and blasting hole drilling and jet-grouting.

MAIN SPECIFICATIONS：

1. The drill rig is withmechanical transmission and hydraulic feed, drill hole dia. is mainly110—130mm(can reach 180mm), drilling capacity 60 m, can drill at any anglebetween horizontal and vertical.

2. Long feeding stroke reaching2300 mm with 2 m drill rod.

3. Using with rotation drillingand percussion –rotation drilling, drill efficiently.

4. Support cylinder, it is easyto adjust the angle of the mast.

5. With crawler, it is easy andfast to find out the drill hole position.

Q: What brand is good for rotary drilling machine?: About aftermarket. CSR mainly rely on after-sales service and Caterpillar after-sales system. Zhonglian, 31, Xugong are their own aftermarket forces. Of course。 Many of the Carter chassis are Caterpillar's men. 31 aftermarket system in mid 2011 last year. Some relaxation. A lot of people ran (I was in Beijing). Many of my friends have gone, the specific reason seems to be 31 restructuring. So at this stage do not superstition 31 aftermarket. A lot of people are new people.

Q: What's the difference between the main oil pump imported from the rotary drilling rig and the home made main pump?: The rotary drilling rig has two winches, one main hoist and one auxiliary winding, wherein the auxiliary winding is of some auxiliary function, such as hanging a protecting cylinder or something, and the main hoist is used for lifting the drill pipe.

Q: How many types of rotary drilling rigs should be used for entering ten meters of weathered sandstone in the rock?: I now have a 31 SR280R rock drilling machine, hit ten meters of weathered sandstone, the estimated efficiency is not high, I suggest you can use 31 rotary drilling rig SR285RC8 or combination rotary drilling rig ZR360.

Q: Rexroth leveling sensor rotarydrilling rig: Solar term door position sensorRole: throttle position sensor is to monitor the throttle angle of opening size, determine idle speed, full load and acceleration and deceleration conditions to implement and throttle opening stateCorresponding fuel injection control. Failure effect: idle speed is high or low, or cause runaway phenomenon.

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: Can rotary drilling machine be used in rock layer?: No, because of the outside! The rock is rather hard, while the rotary drilling rig is suitable for the formation of scattered formations

Q: How many piles per day can the bored pile foundation be 400mm and the pile is 25 meters long?: 1 、 impact drilling hole: adapt to relatively soft formation.2, rotating drilling hole: adapt to relatively hard strata or gravel layer, backfill and other complex geological conditions.3. Hole drilling of casing drilling machine: it is suitable for stratum with flowing sand and underground water.4. Drilling by rotary drilling machine5. Drilling under karst geological conditions6, reinforced cage, concrete7 、 deepwater drilling pile fixed platform

Q: I love inventing super rotary drilling rigs. Can they dig wells? Can they move rocks? How deep can they hit?: Now, the rotary drilling will be replaced by the new double power wells drilled by the China shipping line

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.
