1. Application


 During construction of high-rise buildings, high efficient and reliable communication between construction lifter passengers and the lifter cage driver is very important.To make the lifter run more efficient and make the communication between lifter passenger and operator more reliable, this system is designed by our company for such needs.


2. Specifics

 

Wireless technology is used for the communication between the host and pagers. The host applies micro processing chip,which can automatically detect calling signals and avoid the comflicts due to multiple floor pagers send the calling signal simultaneously.It has very friendly operating interface. Any passenger on whatever floor can send signal through the pager, and the host installed in the lifter cage driving room will show the calling floor number, then the operator will drive the lifter cage to the corresponding floor, which hugely improves working efficiency of the lifter. This system applies wireless alarm frequency band,frequency-stabilizing and anti-cochannel interference technology, which ganrantees working stability, long distance communication and anti-interference.


3. Composition


Each system composes two displaying control units(named Host) and dozens of calling switch boxes (named Pagers, maximum 63 pieces so far). Each host is installed on the control panel in the lifter cage driving room, and the pagers are installed on each floor correspondingly. All pagers are powered just by dry batteries which makes power source wiring not necessary, very easy to install and use.

 Wireless communication technology is adopted between hosts and pagers. No need to setup wiring for signal transmission which makes the installation

piece of cake.

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: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:How do the welding parts in the welding drawings of the machine parts indicate the technical requirements of the drawings?
With what groove related, open groove is not the same, marking is not the same, "welding structure" reference to our specialized courses
Q:What are the details of construction machinery parts in sand casting?
(3) equipped with fittings, installation type air switch and air shower room installed in the furnace. (2) all kinds of vehicle tracks, transmitters, differential pressure and buttons are all materials other than the equipment body. (3) rotating filter network circulating water system for equipment, induction phase shifter, manhole and other various products embedded parts, clean bench, meter, scientific research and other functions of the machine, and pipeline safety device, railing, peep hole, ventilation air heater (1):
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 is the use of spare parts prices in Chinese market by foreign companies?

Q:What type of industry does the machinery and building accessories processing belong to?
There are only three tax categories in our country: 1 consumption tax, 2 VAT, 3 special tax (agriculture). Therefore, as long as the manufacturing or processing of industrial value added tax on enterprises. It has nothing to do with the economic nature, classification and categories of an enterprise.
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: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.)
Q:What are the sectors of machine building and parts processing?
Industry to classify, it is not very strict. For example, the insurance industry, mining, energy, food, hotels, real estate services industry, garment industry, advertising industry, aerospace, aviation, chemical, chemical, construction, health care, education, training, computer, metal smelting, fire, police, soldiers, accounting, beauty, body, media, publishing, wood, paper retail, wholesale, agriculture, tourism, justice, lawyers, sports, sports, arts, entertainment, medical, art, design, banking, finance, Internet, music, dance, postal, courier, transport, consulting services.
