Product Description:

1 Application

  JK16A-100 AC limit switch is mainly used to 50HZ(60HZ),rated working voltage to 380V(440V),rated working current is 100A loop powered of construction hoisting.

  When the limit switch of the hoisting is out of working,use it to cut the general power supply of hoisting console,to realize the terminal protection.

   This cover of the product adopts the aluminiun alloy injection moulding makes it beautiful and solid.The switch contact inside is exquisite and accurate,to reudce the product size reasonable, will safety satisfied the terminal protection of construction hoisting.

Q:What measures can effectively reduce the construction accident rate?
Hefei construction workers training _ fail safe design: in the part of the system, equipment malfunction or damage, can also ensure the safety of safety and technical measures known as fault - Safety Design in a certain period of time (fail-safe). Generally speaking, through careful technical design, the system and equipment are in a low energy state when the fault occurs, thus preventing the unexpected release of energy. For example, a fuse in an electrical system is a typical fault - Safety Design; when the system is overloaded, the fuse is fused and the circuit is disconnected to ensure safety. Although the fail safe design is an effective measure of safe technology, but considering the fail safe design itself may not work due to failure, so the choice of safety technical measures should not give priority to the use of.
Q:What is equipment manufacturing and machinery manufacturing? What's the difference between them?
At present, other countries in the world, including international organizations, have not put forward the concept of equipment manufacturing. The concept of equipment manufacturing industry is unique to our country. Its formal appearance was seen in the central economic work conference in 1998, which explicitly stated: "we must energetically develop the equipment manufacturing industry."". (central economic work conference: Economic Daily, December 10, 1998, first edition) The core of the manufacturing industry is equipment manufacturing. People do not have the same understanding of equipment manufacturing industry, and there is no consensus definition and scope definition. It is generally believed that the manufacturing sector consists of the equipment manufacturing industry and the final consumer goods manufacturing industry. Equipment manufacturing industry is the general term of the industry which provides the production technology and equipment for the simple reproduction and extended reproduction of the national economy, namely the machine manufacturing industry for producing machines".
Q:Where are the mechanical pressurization air supply facilities set up?
When the smoke proof staircase and antechamber antechamber, fire elevator or common antechamber parts can be opened outside the window, can use the natural ventilation, resulting in a stairwell with or common antechamber in the use of natural smoke exhaust with pressurized air supply arrangement of diversified combinations, and the two exhaust can not be shared.
Q:Where was the construction machinery conference held in 2015?
Co organizer: BMW (Chinese) Engineering Machinery Company Limited, Shandong Lingong Construction Machinery Co, Limited by Share Ltd, Shantui construction machinery Futian leiwo international heavy industry Limited by Share Ltd, Shandong Chang Linzhu Machinery Group Limited by Share Ltd, Shandong rhinos Engineering Machinery Company Limited, Beijing Tianshun Hydraulic Technology Co., Ltd. Ji'nan the Great Wall Andy Machinery Co. Ltd., Langfang Deji machinery Polytron Technologies Inc, Tai'an Dongyue Heavy Industry Co. Ltd.
Q:Construction Engineering, moving equipment and stationary equipment, respectively
1, moving equipment refers to the rotating device driven by the drive (that is, energy consumption of equipment), such as pumps, compressors, fans, etc., the energy can be electric power, pneumatic power, steam power, etc..
Q:Construction machinery production need to deal with what documents?
The person in charge of the enterprise, the person in charge of the project, full-time safety management personnel in "safety assessment qualified" column content according to the "three persons" Safety Assessment Certificate (fill in the contents of enterprise work safety management staff should meet the enterprise production safety management, the safety management department staff with the qualification to the total contract for not less than 5, not less than 3 professional contracting labor subcontracting, not less than 1; the construction site should be equipped with full-time safety management personnel according to the project size can be determined, according to the construction area of less than 10 thousand M2 project has at least a part-time staff of more than 10 thousand M2; project 1 - 2 full-time staff; more than 50 thousand M2 large sites, according to different professional safety management group);
Q:What are the mechanical drawing software?
The 3D map only contact with SolidWords and Pro/E, Pro/E is better than Solidwords in general, but Solidwords is very simple to use, see Help tutorials you can learn to draw a three-dimensional map is not particularly complex easily to estimate a few days is enough. But any one of the two kinds of software, want to do not understand the words, expert advice is not really easy. UG and MasterCAM haven't touched much, but I've heard that it's suitable for processing stereogram.
Q:Where does Heilongjiang do the most construction machinery?
It is mainly used for national defense construction project, the construction of transportation, energy industry construction and production, mining and other industrial raw materials, construction and production, forestry and water conservancy construction, industrial and civil construction, city construction and environmental protection.
Q:What functions should be achieved in mechanical structure design?
The function of the mechanical structure is mainly realized by the geometry of the machine parts and the relative position between the parts. The geometry of a part is made up of its surface, and a part usually has a number of surfaces, some of which are in direct contact with the surface of other parts, and this part of the surface is referred to as the functional surface. The connecting part between the functional surfaces is called the join surface
Q:How are the machine parts stacked?
Classification ah! Put small pieces of different sizes and functions into boxes and attach labels; larger items can be placed outside in a certain order (for example, function, length, value, etc.)
