KatanzaroElectInstallation and dismantling personnel and drivers should hold certificates to work.
When applying a normal force of 300N to any position on either side of the door using a rigid 5000mm2 square or circular flat surface in the locked position of the landing door, the door should be able to withstand and have no deformation; - Deformation not exceeding 30mm; After the test, it worked normally.
Katanzaro.Precautions during operation: Mechanical operations should be gentle and smooth, otherwise impact loads will inevitably occur, causing frequent mechanical failures and greatly shortening the service life. Generated during homework
During normal operation, the horizontal distance between the closed cage door and the closed landing door should not exceed 150mm. Otherwise measures should be taken to make it meet the requirements, or side protection devices at the entrance of the landing station that meet the requirements should be equipped. The distance between any opening between the side protection device and the hanging cage or landing door should not exceed 150mm.
.The wall bracket of the construction electric elevator should be intact and reliably fixed, and its attachment distance, wall bracket spacing, and end height must comply with the requirements of the 'User Manual'. The angle between the plane of the wall bracket and the normal direction of the attachment surface should not exceed 8 degrees;. When the attachment device does not meet the requirements of the 'User Manual' due to conditions, its calculation sheet, design, and production materials should be confirmed by the manufacturer or reviewed by the technical leader of the installation unit, and verified by experts.
Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.
Installation and dismantling personnel and drivers should hold certificates to work.
Setting requirements: Drainage measures should be set up for the foundation of construction electric elevators to ensure smooth drainage.
If the set screw is loose, be sure to pin it tightly to prevent accidents caused by the shaft pin falling off. Hydraulic oil should be kept clean and replaced every 6 months.
The setting of the cable guide frame should comply with the user manual and regulatory requirements.
production.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.
Principle of electric elevator rotary valve: When the electric elevator rises,Katanzaro2 meter electric lifting platform,KatanzaroElectric guide rail elevator, the rotary valve will automatically open. To close the plug valve, it is necessary to first turn the handle to turn the plug to a 90 degree position until it is closed, and then turn the transmission handwheel to lower the plug and achieve sealing.
The advantages and disadvantages of several commonly used electric lifting mechanisms are as follows: hydraulic electric lifting mechanisms: using hydraulic technology, smooth lifting and low noise.
Once again, weekly inspections should be conducted to check whether the connecting screws at various parts of the lifting platform are tightened, whether the sealing rings are damaged or ineffective whether there is a lack of hydraulic oil, and whether the oil cylinder is leaking. It is necessary to clean the lifting frame, scissors,KatanzaroElevator scissor electric, wiring, and oil cylinder once a week to avoid dust and debris affecting normal operation.
Direct labor.The scaffolding of the parking platform should be laid tightly and firmly.
Electric lifting machinery, as an important product of social development in China, has a high social status and has now become an irreplaceable operational tool in our mainstream goods. The hydraulic pump station is the heart position of electric lifting machinery, which greatly tests the professionalism and attention of operators. It is our common responsibility to inspect it and ensure the daily use of machinery. Let's take a look at a few common sense issues: the manufacturer of electric elevators is to ensure the correctness of the power connection, and there should be no misconnection or leakage; Pay attention to cleaning work in daily life and do not allow stains to corrode it; When standing still, it is necessary to always pay attention to the abnormalities of the pump station; It is very normal for us to encounter some problems when using hydraulic boarding bridges, we don't have to worry too much. However, when there is a problem with the hydraulic boarding bridge, only a timely solution is the correct response. Below is an introduction to some common faults of the hydraulic boarding bridge and specific solutions: the hydraulic boarding bridge must be repaired while hanging and supporting the working platform of the lifting platform to avoid sudden descent of the lifting platform, causing unnecessary casualties; 2. Do not adjust the overflow valve arbitrarily. Because every component in the hydraulic system operates at a specified pressure, once the relief valve is adjusted, it may cause abnormal operation of the hydraulic system, causing unnecessary damage to people, machines, and objects; Non professional personnel are not allowed to disassemble electrical appliances at will to prevent electric shock or incorrect connection.
Setting requirements: The spacing of wall brackets along the vertical direction should comply with the provisions of the user manual.
Katanzaro.When the wall bracket cannot meet the requirements of the construction site, it should be designed and calculated separately.
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
