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, strength, stability, etc., and the production should meet the design requirements.
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.
southern suburbs.Setting requirements: Buffers should be installed below the suspension cage and counterweight running channel.
When the foundation is set on the roof or floor structure, the bearing capacity of its supporting structure should be checked.
.From the above comparison, it can be seen that hydraulic electric lifting mechanisms have stable lifting low noise, long service life, large load bearing capacity, and are relatively simple, making them suitable for use in stage equipment.
When a rigid 5000mm2 square or circular flat surface is applied with a normal force of 600N to either side of the door the door may not meet the above requirements, but safety should be maintained.
Setting requirements: When the distance between the outer edge of the construction electric elevator and the external overhead power line cannot meet the requirements of a small safety distance, the side protection device for the landing entrance should be equipped.
Precautions during operation: Mechanical operations should be gentle and smooth, and mechanical operations should be avoided, otherwise impact loads will inevitably occur, causing frequent mechanical failures and greatly shortening the service life. Generated during homework
The end height of the guide rail frame above the high attachment point should comply with the provisions of the user manual.
Good reputation.The verticality of the guide rail frame should meet the requirements of the specifications.
High lifting height, using side mounted oil cylinders, stable operation, noise free, easy maintenance,southern suburbsElectric banner elevator, and longer service life.
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, and the main protective accessories include safety belts, guardrails, platforms and stairs, etc.
Test results.It is reported that a fixed electric elevator has good lifting stability and can only be used for fixed operations, making high-altitude operations easier
.
Double layer steel mesh: The diameter of the steel bars is 12mm, with a spacing of 200mm.
southern suburbs.The full height landing door should meet the following requirements: the net height of the landing door opening should not be less than 0m. In special circumstances, 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. (Article 1 of GB26557-2011)
Speed limiter. To prevent the driving speed from exceeding the normal speed. A speedometer should be installed (not required for floors below or including the second floor) which is an individual mechanism that is integrated with a safety clamp; The entrance and exit of the passenger compartment should be equipped with safety doors. Public places, family dormitories, and
The bearing capacity of the ground under the concrete foundation plate should be greater than 0.15Mpa.
