Gdansk ancient
GdanskThree meSetting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.
With the continuous improvement of urbanization level in China, the number of high-rise buildings in urban areas has sharply increased, and the height of buildings has also continued to grow. This has created a demand for high-altitude lifting platform vehicles. Therefore, in order to meet the needs of the domestic market and the public, efforts will inevitably be made to design and produce high-altitude lifting platform vehicles.
Gdansk ancient city.The water cooling of hydraulic stations is generally tubular water cooling. The selection is based on the heat load to calculate the heat exchange area, while the air-cooled electric elevator uses an air cooler to calculate the heat exchange capacity based on the heat load. Then,Gdansk ancient city3 meter small electric elevator, these two types of cooling are different and have significant differences.
Construction electric elevators outside the lightning protection range
.Before operating the construction electric elevator, routine inspections should be carried out according to regulations and inspection records should be filled out.
Chain type electric lifting mechanism: With a good guiding mechanism, it can ensure that the equipment does not tilt during operation. Gear and rack electric lifting mechanism: precise transmission and high cost.
The list of materials for making landing doors is as follows: Table 1: List of materials for making landing doors. Landing doors should be installed at the entrance of each landing station, and the landing doors should function properly.
When the landing door is closed, the full width of the lifting passage opening should be covered.
The water cooling of hydraulic stations is generally tubular water cooling. The selection is based on the heat load to calculate the heat exchange area, while the air-cooled electric elevator uses an air cooler to calculate the heat exchange capacity based on the heat load. Then, the selection calculation is carried out under the condition of satisfying the flow rate. So, these two types of cooling are different and have significant differences.
Acceptance: Concrete strength grade C30, strength testing report.
How many?.According to the needs of different performance genres, the form of the stage can be changed. For example using an orchestra pit lift can combine a framed stage with a large lip or even an extended stage. In an experimental theater, using a lift can make the theater have various forms such as an end stage, an extended stage, an island stage, an intermediate stage, a T-shaped stage, or a hall.
Safety performance: Electric elevators not only have the safety device of traditional traction elevators, but also have an overflow valve to prevent excessive system pressure during upward movement
When the wall bracket cannot meet the requirements of the construction site, it should be designed and calculated separately.
Tank oil temperature protection: When the oil temperature in the tank exceeds the standard setting value, the oil temperature protection device sends a signal to suspend the use of the elevator. The elevator can only be started when the oil temperature drops
build.Low level doors should be equipped with interlocking devices that can verify their closed and locked positions. The action of this interlocking device should be at the entrance of the cage. Simple use should not interfere with the operation of the interlocking device. The attached wall bracket should use matching standard products. When the wall bracket cannot meet the requirements of the construction site, it should be designed separately. The design of the wall bracket should meet the requirements of component stiffness, stability, etc., and the production should meet the design requirements.
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 the damage to the hydraulic system is very large. Therefore, it will simply form pipeline corrosion, water vaporization,Gdansk ancient cityFolding electric elevator,Gdansk ancient city2 meter electric elevator, 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.
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.
Gdansk ancient city.The safety distance between the outer edge of the upper part of the landing door and the moving parts of the electric elevator during normal operation should not be less than 0.75m; If the rated speed is not greater than 0.7m/s, the safety distance can be 0.40m.
Civil engineering advantages: The pit depth of the guide rail type lifting platform is generally around 150-300mm, and the top layer is not affected. It can be customized according to the location and environment.
Emergency manual valve: In case of power failure
