Product Description:



1 Application

  JK16-100 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 engineering plastic injection moulding makes it beautiful and solid.The waterproof performance is high,the combination of contact cam inside is accurate,will safety satisfied the terminal protection of construction hoisting.

Q:What measures can effectively reduce the construction accident rate?
Hefei construction workers training _ eliminate dangerous source: eliminate the risk source of the system can fundamentally prevent accidents. But an important point of system safety is that it is impossible to completely eliminate all sources of danger and that people can only selectively eliminate several specific sources of danger. Generally speaking, when the risk of a dangerous source is higher, we should first consider whether we can take measures to eliminate it. A dangerous source can be completely eliminated by selecting the proper production process, technology, equipment, reasonable design, structural form or suitable raw material. For example: instead of the power system with pneumatic or hydraulic system, to prevent the occurrence of electrical accidents; instead of compressed air system for hydraulic system, to avoid the pressure vessel, pipeline rupture caused by shock wave; with incombustible materials instead of combustible materials, to prevent the occurrence of fire. It should be noted that sometimes measures are taken to eliminate certain sources of danger, but new sources of danger may be brought about. For example, an electric pneumatic system instead of a power system can prevent electrical accidents, but a physical explosion accident may occur in the compressed air system.
Q:What is equipment manufacturing and machinery manufacturing? What's the difference between them?
Equipment manufacturing, also known as equipment industry, mainly refers to the capital goods manufacturing industry, is to meet the needs of the development of the national economy departments and national security needs and manufacture all kinds of technical equipment industry collectively. According to the national economy sector, its range of products including investment manufactured goods machinery electronics and ordnance industry, belonging to the metal products industry, general equipment manufacturing industry, special equipment manufacturing, transportation equipment manufacturing, electrical equipment and equipment manufacturing industry, electronics and communications equipment manufacturing, instrumentation and cultural office the equipment manufacturing industry in the 7 major categories of 185 kinds.
Q:What are the main functions of construction equipment monitoring system?
To date, the console has always been built into blocks, in terms of control functions and number of cameras. Can be assembled according to requirements. In addition, the character generator is also arranged in the total time and address on the console, the date and time, minutes and seconds are displayed by this device, and be put in place to monitor the address and name display. It can be recorded on the video recorder, so that it will be convenient for future reference.
Q:Where was the construction machinery conference held in 2015?
Support unit: Automobile and engineering machinery parts testing institute, Qihe Economic Development Zone, Shandong Province, Shandong Jiaotong University, Mechanical Engineering Institute, Qingzhou Engineering Machinery Industry Association, three, China Railway ten Bureau, in a company, China water conservancy and hydropower Sixth Engineering Bureau Co., Shandong high speed group limited company, the China Metallurgical Construction Group Limited, China Railway Construction Group, Shandong road fourteen, Shandong the Yellow River Engineering Bureau Group Co. Ltd., Ji'nan City Highway Bureau, Dezhou City Highway Bureau, Tai'an City Highway Bureau, Jining City Highway Bureau, Laiwu City Highway Bureau, Shandong WorldCom Highway Construction Co. Ltd.
Q:Mechanical bearings, all types? Roughly
Spherical roller bearings have two raceways in the inner and outer ring raceways between spherical assembly, a drum shaped roller bearings. The center of curvature of the raceway of the outer race is consistent with the center of the bearing, so it has the same self-aligning function as the self-aligning ball bearing. When the axle and shell are bent, the axial load in two directions can be automatically adjusted. Radial load capacity, suitable for heavy load and impact load. Inner diameter is tapered bore bearings can be installed directly. Or the use of tight sets, the demolition cylinder installed on the cylindrical shaft. The cage uses a steel plate holder, a polyamide forming cage and a copper alloy car holder.
Q:Construction machinery production need to deal with what documents?
At all levels of production safety responsibility system, mainly refers to: the legal representative of the safe production responsibility system; the responsible person in charge of safety production safety responsibility system; the technical director (Chief Engineer) production safety responsibility system; the safety department (Department) Changan production responsibility system; responsibility for production safety, the project manager; specifically (and) post safety responsibility system for production safety; construction technician (technician), safety production responsibility system; 8 class (Group) Changan production responsibility system; workers, production safety responsibility system. Departments responsible for production safety system, mainly in accordance with the functions of enterprises set up departments, the corresponding formulation of the responsibility system for safety in production.
Q:What are the principles, performances and uses of the commonly used construction machinery equipment?
3. excavator principle: Excavator through the hydraulic pump to the power of the engine to hydraulic motors, hydraulic cylinders and other executive components, to promote the operation of the device, so as to complete all kinds of operations. Performance: new Isuzu engine, euro II emission, international standards, more into power for you, lower fuel consumption; with high torque rotary mechanism, improve the starting torque of rotary and rotary reducing drift; with a new high efficiency, low noise, large displacement of the main pump, provided high efficiency machine to deal with the bad working conditions; and to strengthen the work of device according to the quarry condition, increase its reliability; strengthen the lengthened crawler frame, while reducing the ground pressure, improve the performance of the fault diagnosis system; new, prolong the overhaul cycle, reduce maintenance cost. Use: 1) building and building foundation excavation; (2) mining soil, stripping mining field covering layer; (3) the quarry, tunnel, underground powerhouse and heap loading operation in the field of material; 4) excavation channel, canal and waterway dredging; (5) replacement of the devices can be pouring lifting and installation, piling, rammed earth etc..
Q:Changsha Sanlian Building Machinery Fittings Factory
The company in Changsha Hongdun business online can not find, provided by his address: two Changsha section of Xingsha Economic Development Zone Yuan Ming Road, I checked 114 specially call 12580 to booking the hotel near the road, not the road. Definitely a liar.
Q:What are the mixing arms of the concrete mixer?
Mixing arm concrete mixer is a component of the mixing arm itself and divided into lateral mixing arm (positive and negative points), stirring arm (also have positive and negative points), stirring arm below is the bearing seat connected, connected with 4 sets of high strength bolts with stirring arm. The top is equipped with wear-resistant mixing blades, connecting with mixing blades, high-strength bolts 2 sets. In addition, some manufacturers have designed mixing side bonded shaft swivel, is installed in the interval between the stirring arm fixed and rotated in two ways.
Q:What is the use of spare parts prices in Chinese market by foreign companies?
But there is always somebody to ask, just like a college paper, where everyone can read or keep secrets, but collecting them and sending them to foreigners is a sign of treason
