Fuji Custom Speed Elevators

Elevator safety protection acceptance regulations The elevator safety protection acceptance must meet the following regulations: 1. Phase failure or phase failure protection device or function When any one phase of the three-phase power supply of the control cabinet is discoected or any two phases are coected incorrectly, the phase failure or phase failure protection device or function shall prevent the elevator from dangerous failures. Note:

When the wrong phase does not affect the normal operation of the elevator, there is no wrong phase protection device or function. 2. Short-circuit and overload protection device The power circuit, control circuit, and safety circuit must have a short-circuit protection device that matches the load; the power circuit must have an overload protection device. 3. Speed limiter The car (counterweight, counterweight) downward sign on the speed limiter must match the actual downward direction of the car (counterweight, counterweight).

The rated speed and operating speed on the nameplate of the speed limiter must be consistent with the elevator being inspected. 4. Safety gear Safety gear must conform to its type test certificate. 5. The buffer buffer must conform to its type test certificate. 6. Door lock device The door lock device must conform to its type test certificate. 7.

Upper and lower limit Freight Elevator The upper and lower limit switches must be safety contacts, and they must operate normally during the operation test at the terminal position. Before the car or counterweight (if any) touches the buffer, it must move, and when the buffer is fully compressed, the operating state is maintained. 8. The car top, machine room (if any), pulley room (if any), and pit stop devices located on the car top, machine room (if any), pulley room (if any), and pit stop devices must operate normally. 

The elevator facilitates China hospital elevator daily life and accelerates the pace of social development. However, in recent years, the frequent failure of elevators, known as the 'safest means of transportation', has caused a large number of casualties. It has sounded the alarm for us and it is necessary to raise elevator safety to the height of public safety. As a special equipment of electromechanical synthesis, the elevator is technically similar to a computer crash and the car stalls, which is difficult to completely avoid technically. Judging from the analysis of historical elevator accident cases, the trapped people often fail to get professional rescue in time, causing secondary accidents and causing casualties.

How to provide effective professional rescue services to the trapped in time is the key to avoiding elevator safety accidents. According to this situation, this article mainly introduces the working principle of elevators, the types of elevator accidents and the treatment measures. Keywords: Elevator accident cause rescue method According to the statistics of the State Administration of Quality Supervision, Inspection and Quarantine, at present, China's elevator production, elevator ownership, and aual growth are the world's first. As of the end of 2012, the total number of elevators in use in China reached 4.216 million, and it is growing at a rapid rate of about 20% per year.

The ever-expanding number of elevators has exacerbated the occurrence of elevator accidents. Statistics from the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of my country show that elevator accidents in China cause more than 40 casualties each year, especially since 2012, elevator accidents have been on the rise. In recent years, several domestic cities have experienced elevator shock accidents one after another.

The tragedies are shocking. For example, on April 10, 2012, an elevator in the Shanghai World Financial Center suddenly failed. Nearly 20 white-collar workers were confined in the elevator car and traveled back and forth between floors 1 to 52. Elevator accidents in Qianxinan Prefecture, Guizhou Province are also uncommon. For example, at 0:52 am ontwo people were trapped in the elevator on the second floor of the first community in Xingyi City, Guizhou Province.
