Wireless remote and alarm devices (when the elevator malfunctions，Elevators can send fault information to mobile phones through wireless devices， and use mobile phones to send signals to simplify the elevator The main parameters refer to the rated load and rated speed.
4With the continuous development of elevator technology， the speed of elevators is getting higher and higher， medium， and low speed elevators is also correspondingly increasing.
lMason AlfordThe call button on each floor is no longer working and the call is cut off.
In ，Vertical barrier-free lifting platform the annual production of elevators in Chinas elevator industry exceeded units for the first time. The third wave of development in Chinas elevator industry since the reform and opening up is rising. The first occurrence occurred from to and the second occurrence occurred from to . The milestones for the annual production growth of elevators in China are shown in the table below.
BMengsangConstruction elevator is a mechanical device that uses gear and rack meshing (including pin tooth transmission and chain transmission，MatsalkaRear flip hydraulic plate flipperBreak-in and maintenance or steel wire rope lifting) to make the suspension cage move vertically or obliquely， used to transport personnel or materials， mainly used in construction and maintenance. It can also serve as a long-term vertical transportation machinery for warehouses， docks， docks， and chimneys.
TpThese phenomena are not elevator malfunctions. When the elevator is fully loaded， the elevator does not stop: to avoid overloading， the elevator car no longer responds to the next stations outbound call.
In ，Hua Cailin，Vertical barrier-free lifting platform who used to work as a foreman at the Shenchangyang branch of the American company， privately opened the Huakaiji Elevator Hydroelectric Railway Factory at No. ， Lane ， Changde Road Shanghai， engaged in elevator installation and maintenance business. This factory became the first elevator engineering enterprise established by Chinese people.
The seat elevator person sits on a chair driven by an electric motor， and the button on the chair handle causes the power drive device at the bottom of the chair to drive the person chair up and down along the guide rail of the staircase railing
yDrive Method&# & Flash; Worm gear and worm traction machineThe advantages of permanent magnet synchronous gearless traction machine compared to worm gear and worm traction machine are: simple and compact structure， small volume， and light weight. Due to the fact that the permanent magnet synchronous traction machine is directly driven， without worm gear or worm drive， and without the stator coil that occupies a significant amount of space required for asynchronous motors，Vertical barrier-free lifting platform its main material is high energy density， high residual magnetic induction，MatsalkaRear flip hydraulic plate flipperBreak-in and maintenance and high coercive force neodymium iron boron. Its air gap magnetic density generally reaches over .T， so it can achieve small volume and light weight.
FAs an elevator user， the first step is to understand the types， main parameters， and performance indicators of the required elevators， and learn and master the basic knowledge of elevators.
SsystemThe elevator stops on a certain floor for a long time without moving or responding to external calls: it is possible that the elevator administrator has activated the driver operation function.
cSRated load and theoretical transportation capacity rated load. The rated load is the main parameter of an elevator， which refers to the designed load capacity of the elevator. Usually divided into kg， kg，Home elevator, villa home elevator, small home elevator, home elevator brand - home elevator manufacturer kgDifferent grades such as kg， kg， kg， kg， kg kg， kg etc. Among them， the weight limit of the utility elevator is below kg; The weight series of passenger elevators are kg， kg， kg， kg， kg， kg， hospital bed elevators are kg， kg， and cargo elevators are kg， kg， kg， kg， kg.
Passengers wearing long skirts and strapping sandals when riding on the escalator should try to stand slightly in the middle of the escalator to prevent shoes and clothing from being drawn into the escalator and causing danger， and to prevent skirts or pants from getting stuck.
On February ， ， the elevator association magazine China Elevator was officially published and publicly distributed both domestically and internationally. China Elevator has become the only official publication in China that specifically introduces elevator technology and market. State Councilor Gu Mu inscribed the title of the publication. Since its inception， the editorial department of China Elevator has actively established communication and cooperation relationships with elevator organizations and magazines both domestically and internationally.
Economic managementpAccording to the analysis of industry insiders， the industry concentration ratio of Chinas elevator industry is constantly improving and the development trend is good. The industrial development pattern has undergone significant changes， showing that the strong are stronger and the weak are weaker， and the industry has entered a reshuffle period. Some brands have started to put into production in the central and western regions， making the industrial layout more reasonable. [] Different types of elevators are set up according to the height， purpose， and passenger flow (or logistics volume) of the building. The basic classification of elevators is roughly as follows.
IKeep the cabin clean and hygienic， and do not smoke or dispose of waste anywhere in the cabin.
The elevator should not be arranged adjacent to the bedroom.
lMason AlfordA household elevator refers to an elevator installed in a private residence for the sole use of a single family member. It can also be installed in buildings used by non single households as a tool for single households to enter their homes. The rated speed of household elevators shall not exceed .m/s. For household elevators without doors， the car travel shall not exceed m， and the rated load capacity shall not exceed KG. Mainly divided into traction elevators， screw elevators， and hydraulic elevators. We need to determine based on the installation environment， such as the area of the villa and the actual environment for installing the elevator. We usually choose the elevator style based on the overall decoration style of the villa when determining the size. This not only does not affect the aesthetics of the villa， but may also result in additional points. The commonly used structure is a traction gantry structure.
wBIn July ， the third session of the China Elevator Association was held in Suzhou， marking the establishment of the China Elevator Association as a first level association and its official name being&quo; China Elevator Association; Establishment of.
