AnshanElectricInstallation and dismantling personnel and drivers should hold certificates to work.
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
Anshan.The shutdown device (emergency stop switch) should be non automatic reset type.
The distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements otherwise protective measures shall be taken.
.Manual pump: When the system malfunctions, the manual pump can be operated to pump high-pressure oil to raise the car to the nearest floor position
When the wall bracket adopts non matching standard products, design calculations should be carried out.
Setting requirements: Drainage measures should be set up for the foundation of construction electric elevators to ensure smooth drainage.
When the distance between the outer edge of the construction electric elevator and the edge line of the external overhead power line cannot meet the requirements in the table above, effective protective measures should be taken.
When adding hydraulic oil, it is also necessary to pay attention to the structure of the oil cylinder. Some oil cylinders are relatively complex internally,AnshanCurved arm electric elevator, and how many lifting operations need to be carried out during filling to fully fill each position of the hydraulic oil. Therefore, when filling, try to add as much as possible, and then test and run the machine empty to see if it reaches the rated position.
The counterweight guide rail should meet the specification requirements.
where.When the door is closed, except for the gap between the lower part of the door that should not exceed 35mm, any through-hole and opening size related to the distance between any door and adjacent moving parts, as well as the gap around the door or the gap between parts, should comply with the provisions of Table 4 of GB 23821-2009.
The safety bulletin board for construction electric elevators should be hung at the protective shed of the electric elevator, 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, and ensure that the lifting platform can be lifted to the rated lifting height.
Advantages of electric elevator rotary valve: Simplify the installation of electric elevator pipelines; The operation is more convenient, and the valve can be opened and closed at any time; The installation of a rotary valve reduces the friction of the sealing components; Compact structure, small size, and space saving; Increased the service life of electric elevator pipelines and solved the problem of easy oil leakage.
wholesaler.To meet the needs of choreographers and choreographers in different plays, different heights of the lifting platform can be used to change the shape of the stage according to the requirements of the choreographers and choreographers in order to adapt to the requirements of the plot for the scenery or venue, and save manpower and material resources for setting up. By using the tilting device of the lifting platform to form a tilted platform, a better highlighting effect can be achieved in various performances. According to the needs of the plot, special atmosphere and effects can be created. Even simple stage machinery often participates in performance activities, creating unexpected atmosphere and effects according to the needs of the plot. For example, using the low-speed descent of the lifting platform to represent a sunken ship in the sea, using the valves on the lifting platform and the sudden disappearance and appearance of actors on the lifting platform.
The inner bearing of the roller in the device is in good condition, and a complete grease film surface is maintained between the curved surface of the roller and the main chord of the aluminum alloy electric elevator. A good grease film surface can reduce wear and noise
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.
Anshan.Operating cost advantage and low failure rate: Due to the use of advanced hydraulic systems and good methods, the operating failure rate can be reduced to a low level.
According to the needs of different performance genres,Anshan6-meter electric elevator, 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 intermediate stage, or a hall.
Drivers of construction electric elevators should hold special construction operations and are not allowed to operate without a certificate.
