5 Typical diagram circuit

QT12 series construction hoisting console, controller, joystick for tower crane

Q:What is a door rack for a construction site? How high is it generally?: Door scaffolding has not yet unified design and product standards, the products of different specifications, quality is inconsistent. Not only for construction units to use and management of great difficulties, is not conducive to the promotion of applications, but also to the construction safety risks. Therefore, it is necessary to organize and issue a unified standard for door scaffolding

Q:Where are the hanging baskets for the building?: It is forbidden to take a stool or put a ladder on a hanging basket to work higher; it is not allowed to work alone in a basket, and no electric machinery or equipment can be placed in the basket;

Q:What are the construction materials, components, fittings and equipment in construction?: : construction engineering materials, components, fittings, equipment, each refers to: 1, engineering materials: engineering materials mainly refers to raw materials. Such as: sand, stone, steel, etc., there is no processing materials. 2, structural parts: the main structure here is the main structure of the building, the two structure and other accessories. Most of the semi-finished products and the structure of part of the installation accessories, such as: beam beam, continuous beam, beam, beam, cantilever beam, curved beam; steel, timber, concrete beam.

Q:What is the difference and connection between equipment manufacturing and machine building?: In accordance with the standards of classification, including metal products, general machinery manufacturing, machinery manufacturing, transportation equipment manufacturing, electronic and communication equipment manufacturing industry, electrical machinery and equipment manufacturing, instrumentation and office machinery manufacturing seven deducted 186 small consumer related manufacturing industry after class. Equivalent to the European countries referred to as "capital goods manufacturing", that is, we often say "the production of means of production industry."".

Q:What are the world famous mechanical equipment exhibition?: 3, the French international civil engineering and Construction Machinery Exhibition (INTERMAT) the European Construction Committee (CECE), founded in 1988, tenth in 2015, is one of the three famous exhibition of world engineering machinery and construction machinery field, three years. France INTERMAT exhibition exhibits covering mining machinery, earthmoving machinery, concrete machinery, lifting machinery, pavement and compaction machinery, piling machinery, industrial vehicles, pneumatic tools, drilling machinery, building materials machinery, mining machinery and other engineering and construction machinery and spare parts industry. Paris International Construction Machinery Exhibition in Europe - the Middle East - Africa (EMEA) region has a unique position.

Q:What is the use of spare parts prices in Chinese market by foreign companies?: You might be gathering information for him. You have no data for one person, if there are several people? They can analyze a lot of things through big data. You can't find out, you're OK. Once you find out, your whole life is over.

Q:Changsha Sanlian Building Machinery Fittings Factory: In addition, you can check the input path, or the name of the unit on the map. It will remind you that there is no unit in Changsha and no way. In addition, we received a fax, saying that you want to order what goods, may wish to go to the other party's local industrial and commercial Red Shield network to check whether there is this unit

Q:What are the sub projects of a construction project?: Appendix B Construction Engineering Division (sub branch) engineering, sub project division, B.0.1 Construction Engineering Division (sub branch), engineering, sub projects can be divided into table B.0.1. Table B.0.1 division number of construction works, sub works and sub projects

Q:What are the principles, performances and uses of the commonly used construction machinery equipment?: 1.: concrete pump principle: concrete pump driven by motor pump system, the conveying capacity of constant power control of hydraulic system of concrete pump automatic control, manual control can also be used to select the concrete delivery volume. Performance: 1. using the hydraulic system of double pump double open circuit, the main pump valve swing circuit and S circuit are separate for fault diagnosis and removal; 2. pumping hydraulic circuit adopts the main valve pilot pressure control; 3. hydraulic system has safe relief protection, while the main pumping system overpressure, oil pump automatic pressure cutting off; 4. switching circuit with constant voltage supply with the energy storage device, so as to guarantee reliable swayingforce large and have the advantages of energy saving effect; 5. pumps and valves are used continuously, the world famous brand is more reasonable and more reliable and easily realized commodity concrete transport quantity adjustment; 6. hydraulic pipeline with cone seal pipe joint sealing material; 7. pumping circuit adopts a valve block mode of high and low voltage switch, convenient, no leakage; 8. with oil and oil filter technology, foreign body into the hydraulic system. Further improve the hydraulic system reliability and component life; 9. hydraulic hose hose. Use: widely used in commercial concrete demand for large, high grade and strict quality requirements, long conveying distance of high-rise buildings, municipal construction, electric power, energy, transportation and other civil and industrial buildings, especially the construction of the narrow space more show its true colour of a hero.

Q:What are the main functions of construction equipment monitoring system?: The total of the console cameras and auxiliary equipment (such as camera, PTZ, shield) control generally adopts the bus mode, a control signal to the camera near the terminal in the terminal box decoding, decoding box will total console from the control signal encoding solution, a control action command signal, a variety of actions to go camera control and auxiliary equipment (such as lens zoom, pan rotation etc.). In the case of some cameras that are close to the control center, in order to save money, the command signal, which is the "on or off" signal, can also be sent directly by the console. In short, according to the composition of the system and requirements, can be considered in order to complete the overall console design requirements or order requirements.
