Product Description:

 

Performance  

●The leading overall  transport full hydraulic rotary drilling rig, can change transport state into  working state rapidly;

●High-performance hydraulic  system and control system in cooperation with Tianjin University CNC Hydraulic  Institute of Technology, which can realize the machine efficient construction  and real-time monitor;

●High security, designed in  strict accordance with European Union safety standards EN791. Meet the  requirements of dynamic and static stability.

■Unique structure of  folding mast can ensure the overall transportation and reduce the transport  size;

■Advanced design of rotary  angle displacement output mechanism and central rotary joint output angular  displacement can get higher reliability;

■Innovative drilling bucket  depth measurement system can show higher accuracy than the average rig;  

■The function of main winch  bottoming protection and priority controlling can make the operation  easier;

■The reversible use of the  driving head’s chain can extend the service life;

■Multi-stage damping  technology of the driving head can ensure the whole construction more  stable;

■The technology of mast  automatic verticality can make the vertical accuracy of the hole higher;  

■The innovative design of  luminous hot wheel can ensure construction in night more safety

■The humanized design of  chassis back can increase storage space efficiently.

New design of two-stage  operating interface can make it more convenient to operate.

Q:AC/DC MACHINERY question,please help me?
746 watts = 1 hp 30 brake hp are going into the sysystem so 30*746 watts is going into the generator = 22,350 watts if 20,000 watts is leaving the system as electrical power, that only leaves 350 watts available for losses.
Q:How does one get a job in construction running machinery?
By machinery I guess you mean backhoes, front loaders, etc. You must have a special license to run the big machines in most states. You can find a school that gives courses to be able to get that license.
Q:Is it necessary to have the automation of engineering machinery and the automation of mechanical design?
Machinery and electronics is the intersection of mechanical and electronic specialties, biased towards automation, machinery is not very fine, the electronic is not very fine, the main direction is to carry out the training of machines and electrical personnel. Construction machinery is mainly to train other non mechanical engineering equipment supporting professionals.
Q:What are the total cost of the project?
Direct costs include direct project costs (labor costs, material costs, construction machinery costs) and measures fee (environmental protection fees, civilized construction costs, safe construction fees, temporary facility fee, night construction fee, two handling fee, large machinery and equipment import and field installation, concrete reinforced concrete template and support fee scaffolding fee, finished project and equipment protection fees, construction fees) precipitation drainage.
Q:What's a good simple workout to do without any machinery or equipment?
I like to take a deck of cards and make each suite represent a certain workout of my choice, and the number of the card tells me how many of them to do. for example: hearts = minutes of jogging in place, or anything cardio spades = pushups or anything upper body clubs = crunches or anything mid section diamonds = squats or anything lower body. and then for face cards jacks = 11 queens = 12 kings = 13 aces = 14 joker = 15 of everything It's like a game where the object is to get through the entire deck.
Q:What is the definition of computer science given by the Association of Computing Machinery?
Computer Science Definition
Q:Friction generates heat and causes wear and tear in machinery yet friction is often needed. Explain briefly?
it has something to do with this: in order for an object to move, it must push off against another object. it is there that friction comes into play. i dont really know the rest.
Q:Are you a cog in the machinery of the universe, or a maestro controlling all about you, or a passenger?
I am in control of my own happiness because no one else is. I do think life is a puzzle in a way and learning something new everyday is a pleasure. However, I enjoy being a passenger. It is one of my favorite things. To just sit back and be along for the ride is always one of life's greatest pleasures - for me anyway. :)
Q:Why do latheists want the unsubstantiated Theory of Machinery taught in schools?
Micro machines are true and they are devolving I have seen it with my own eyes ! They used to be much better constructed but now look like god is creating them in China . * snicker *
Q:What are the common mechanical processing methods?
When turning the inner and outer cylindrical surfaces, the tool moves in a direction parallel to the axis of rotation of the workpiece. When turning the end face or cutting off the workpiece, the tool moves horizontally in the direction perpendicular to the axis of rotation of the workpiece. A circular cone can be machined if the movement of the tool is at an oblique angle to the axis of rotation of the workpiece.
