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: How is the construction of rotary drilling and piling machine built on the floor?: Pile driver is composed of pile hammer, pile support and auxiliary equipment. The pile hammer is attached to two parallel vertical guide rods (commonly called Longmen) at the front of the pile support and hoisted with lifting hooks. The pile foundation is a steel structure tower with a windlass at the back of which is used to lift the pile and hammer. A guide frame consisting of two guide rods is used in front of the pile to control the direction of the pile driving so that the pile can be accurately penetrated into the formation in accordance with the design orientation. The basic technical parameters of a pile driver are impact weight, impact kinetic energy and impact frequency. According to the motion of the pile hammer power source can be divided into hammer, hammer, diesel hammer, hydraulic hammer etc..

Q: How many types of rotary drilling rigs should be used for entering ten meters of weathered sandstone in the rock?: The current domestic rotary drilling rig manufacturers and models are more well-known manufacturers are mainly ZOOMLION, 31 heavy machine, Xugong, CSR, Futian, Shanghai Kim, Tianjin sunward, Bauer, Wujiang geotechnical, Yutong, mainstream rock into the rotary drilling rig has 31 main SR280R into the rock rotary drilling rig, Zoomlion ZR280 360, Xugong, Bauer BG25 into the rock can be, but the price is not high, 31 C8 series rotary recently to participate in the 2014 Shanghai BMW exhibition drill SR285RC8/SR385RC8, is said to have ability to exceed the traditional rock entering into the rock type rotary drilling rig.

Q: How many times a day will the drilling machine be used?: According to geological conditions and diameter of piles, it is usually between 30 and 60 meters

Q: How much is a drill bit?: I don't know. You can buy a rotary drilling rig, or dig it.

Q: What brand is the best for rotary drilling machine?: Although the drilling rig imported from abroad is better than domestic brands.

Q: My rotary drilling rig has broken several rotary drilling pipes. Is it my drill pipe or the reason of my rig?: To Wuhan Geological Engineering Machinery Co., Ltd. to buy drill bar.

Q: How much does a rotary rig for Sany cost? A?: Model: SYR150:160 10000 -180 millionSYR200:250 million -300 millionSYR220:420 million -460 million (31 homemade chassis), 4 million 800 thousand -510 million (Carter 330C chassis, request pay)SYR250:470 million -490 million (31 homemade chassis), 500-530 Wan (Carter 330C chassis, request pay)SYR280:500 million -520 millionSYR360:650 million -700 million (all imports of Caterpillar 345C original chassis, the use of the world's advanced C-13 EFI, cold turbocharged diesel engines, power, noise)

Q: I love inventing super rotary drilling rigs. Can they dig wells? Can they move rocks? How deep can they hit?: Because now the double power head drill wells with rotary drill rod is rotary drill, but few are more than 2 meters in diameter with direct rock itself, very fast, low cost of the machine drill many times than rotary drilling. I suggest you check the pile hole drill on the Internet, or the China Sea Hengtong, it is easy to find information.

Q: Which rotary drilling rig is durable and economical?: There is a very durable FR622D Futian leiwo site, is awesome, Carter chassis, three motor reducer, power head multi speed control, embedding ability of super strong, often machine is an open day, customer service is also very important, you should pay attention to!

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: Domestic rotary drilling rig under normal maintenance, the use of more than 6 years, almost or even longer. The imported equipment maintenance normal use, I feel more than two decades is not a big problem. However, this does not include the production plant equipment production design of abnormal special circumstances and construction operation is not correct, and accidents.
