From the perspective of the safety performance of the machinery itself, those that have undergone national safety certification will not have significant safety issues. The main problem is that after using the electric elevator for a period of time, mechanical components may fall off or be damaged due to various factors. This problem depends on regular inspection and maintenance of the machinery
The net height of the landing door opening should not be less than 8m, and the difference between the net width and the outlet width of the cage door should not exceed 120mm. When the floor door is closed, except for the gap between the lower part of the door that should not exceed 35mm, the size of any through-hole and opening related to the distance between any door and adjacent moving parts, as well as the gap around the door or between parts, should comply with the provisions of Table 4 of 'Mechanical Safety - Safety Distance to Prevent Upper and Lower Limbs from Touching Dangerous Areas' GB23821-2009.
Shanghai.The occurrence of.
Setting requirements: For construction electric elevators that operate in multiple shifts, and drivers should fill out the handover record form according to the standard requirements. The driver should conduct a pre shift inspection and confirm that there are no errors before starting the machine for operation.
.Setting requirements: The verticality deviation of the installation of the guide rail frame of the construction electric elevator should comply with the requirements of the user manual and specifications, as specified in the above table.
Setting requirements: The spacing of wall brackets along the vertical direction should comply with the provisions of the user manual.
Construction electric elevators should be equipped with cable guide frames and comply with regulatory requirements.
There is no need to set up a computer room above the shaft like an elevator, and the top floor height can be installed at least 2.5 meters.
Economic management.Safety grounding device. In order to protect against electrical equipment. The metal casing of electrical equipment and the metal structure of electric elevators should be equipped with a safety grounding device. The grounding wire should operate multiple wires, and the neutral wire should not be arbitrarily held as a safety grounding wire. Its grounding resistance should not exceed 4 ohms; The power supply of the electric elevator can be cut off.
The detailed reason why water cannot be used to flush the hydraulic station is that doing so will corrode the oil tank in the hydraulic station, and once water is mixed in the hydraulic station,ShanghaiPure electric curved arm elevator, the damage to the hydraulic system is very large. Therefore, it will simply form pipeline corrosion, water vaporization, and other phenomena that can cause adverse effects or results for hydraulic electric elevators. Therefore, it is necessary to prevent such actions to ensure the normal operation and service life of the hydraulic station.
Secondly, for the replacement of hydraulic oil on the lifting platform it is recommended to replace it every three months. If the frequency of use is not high, it can be replaced once a year. The hydraulic oil must be clean, and after changing the hydraulic oil, it must be automatically lifted and lowered 2 to 3 times to ensure that the air in the oil cylinder is completely discharged, maintain sufficient space, when the net height of the building entrance is less than 0m, it is allowed to lower the height of the lower door opening, but in any case, the net height of the lower door opening is not less than 8m.
