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:Definition of large mechanical equipment?: The hoisting machinery used in bridge construction can be divided into three categories: light and small lifting equipment, bridge type crane and boom type crane. Light and small lifting equipment, such as jacks, hoists, winches, etc.. Bridge type lifting machinery, such as beam cranes, Longmen cranes and so on. Boom type cranes, such as stationary slewing cranes, tower cranes, truck cranes, tires, crawler cranes, etc..

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 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 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:Mechanical bearings, all types? Roughly: The separable bearing is composed of a raceway and a needle roller and cage assembly that can be arbitrarily assembled with a punched thin raceway (W) or a machined thick raceway (WS). A non separable bearing is an integral bearing consisting of a precision machined raceway and a needle and cage assembly. This type of bearing can bear one-way axial load. With small space, it is beneficial to the compact design of machinery. Most of them only use needle roller and cage assembly, and the installation surface of shaft and shell is used as raceway surface.

Q:Building materials, equipment, components and fittings products must have "three certificates" is what cards?: Product quality certification, also known as product certification, internationally known as qualified certification. According to the 1991 implementation of the "people's Republic of China Quality Certification Management Regulations", the product quality certification is based on the product standard and relevant technical requirements, the certification institution confirmed by the certification and certification marks to prove that a particular product is in conformity with the relevant standards and technical requirements of the corresponding activities.

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 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:How are buildings, installations and materials divided?: Equipment generally includes the following: (1) all kinds of equipment and the equipment with the arrival of accessories, spare parts and equipment attached to the body made of ladders, platforms, railings and pipes. (2) various gauges, instruments and automatic control devices, experimental instruments, instruments and meters in the main part of the equipment. (3) components of equipment, such as oils, chemicals, etc. attached to the equipment body.

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.
