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:Construction machinery, switch to do auto machinery, then can have a good development?
Then you can go to the auto parts company, and like Vientiane company and so on, you need a talent like this, you can consult the company, support you.
Q:Why do mechanical systems usually use nitrogen gas tanks instead of other gases in mechanical engineering?
Especially the cold elements produced in compression are very beneficial to the buffering system. The buffering pillars and tires on the airplane are all used nitrogen, which shows its advantages
Q:Why are construction machinery so sluggish this year?
But now the The Belt and Road construction, as well as the FTA was set up and a series of good news, will bring a new round of opportunities for machinery industry.
Q:Can the construction machinery mortgage?
Mechanical engineering is a fixed asset is mortgage ~ but to see your machine's valuation is how much and you want to loan the proportion of the amount of ~ such as your machine is 1 million ~ but on what is the depreciation of bank valuation of 60~70 million ~ he gave you the loan amount is about half. This valuation is relatively ideal ah ~
Q:What kind of work does a small building mechanic consist of?
This book introduces the mechanical drawings and the construction site of small and medium sized lifting machinery, concrete machinery, steel machinery, woodworking machinery and other mechanical principle, structure, main performance parameters, maintenance, maintenance, use, safety procedures, fault inspection and elimination etc..
Q:What are the companies in the chain of construction machinery in China?
As for the engineering machinery agent listed companies less, turnover of one billion yuan in the construction machinery agent enterprise is massive, so it is difficult to market, even if the listing is and other industries tied listed, Yoshimine agricultural regions such as the Southwest (listed companies) Yoshimine the Great Wall engineering machinery under the (subsidiary) is special do the agency of Engineering machinery.
Q:What is mechanical engineering?
Introduction to mechanical engineering related science and technology as the theoretical basis, combining the technical experience in the production practice, study and solve in the application of discipline development, design, manufacture, installation, use and repair all kinds of machinery in all theoretical and practical problems. Machinery is one of the five essential elements of production and service in modern society (human, capital, energy, material and machinery), and is involved in the production of energy and materials.
Q:Big mechanical engineering machinery, or other, the bigger the better
There are TC2000300 tons of car out of West Germany (flower, crane boom and counterweight need another crane assembled). Steel structure workshop general domestic hoisting crane most commonly used, but must calculate the crane position and radius of gyration. There are 200 tons of motor cranes in Japan in recent years, telescopic rod, fully self-propelled.
Q:How to make simple account for construction machinery rental?
Now many accounting software such as Kingdee U8 ah, ah, ah but you don't know it's really not accounting method, accounting is done, when receiving the money
Q:Please tell me how to use the multimeter to measure those aspects when the working circuit of construction machinery is out of order
Measure the control circuit first, and then measure the motor to short-circuit the ground, then measure whether the interphase is short circuited and check step by step.
