MessinaRail-tyThe design of support points for selecting process parameters is to avoid energy consumption and noise generation due to collision between components and supports during vibration. The supports should be arranged near the nodal line, and the layout principle is: when the aspect ratio of the component is greater than 2, two point supports can be used; When the aspect ratio is close to 1, it is advisable to use or 4-point support.
Folding arm lifting platform product features 01 Folding arm lifting platform High altitude operation platform 360 degree rotation without external power supply, can work across obstacles, lifting smoothly and safely. The curved arm lifting platform adopts a curved arm working arm, and the scope and space of operation are not affected.
Messina.Check the fastening status of the wall bracket, support rod, and bolts and retaining rings between the lifting cargo elevator and the bridge. If they are loose or displaced, they should be checked and tightened
Emergency descent: Handle operation or use of manual pressure relief and activation of emergency battery system to implement emergency descent function safety net.
.The driver shall close and lock the movable doors at both ends of the protective fence before work, and then ring the bell to start. It is strictly prohibited to work with the movable doors of the protective fence open. In case of special circumstances during platform operation, the emergency stop switch can be used to stop the platform. However, during normal operation, it is prohibited to use the emergency stop switch to stop the platform.
When the lifting base plate descends, the safety net below immediately stops running and descends when encountering obstacles.
Drivers should be responsible for supervising the uniform distribution of items transported by the platform on the platform as much as possible to prevent partial loading and prohibit overloading. flat
Now with the arrival of summer, the aluminum alloy lifting platform will certainly suffer from high temperature and rainstorm in summer. It is easy to rust after a long time under this condition, which will seriously shorten the service life of the equipment and cause safety problems. So how should we prevent equipment rust?
There are many operational errors, and due to insufficient understanding of the structure and performance of the machine (especially for new operators), it is easy to cause malfunctions and even mechanical accidents due to operational errors. How to calculate the lifting cargo elevator? A lifting cargo elevator is a heavy lifting mechanical equipment that can manually operate the system's buttons to complete the transportation of goods up and down. The lifting height of the lifting cargo elevator varies from 1 meter to 20 meters, and special specifications of lifting and lowering cargo elevators can be customized according to user requirements According to the type, it can be divided into:; Scissor fork type cargo elevator and guide rail type cargo elevator. Guide rail type elevator is a non scissor fork type cargo elevator, mainly used for the transportation of goods between floors of workshops, steel structure workshops, rooms, and warehouses without pits or machine rooms. Scissor fork type cargo elevators need to be prepared with pits before installation, and the elevator should be fixed and connected in the pit before being connected to the power supply The lifting cargo elevator utilizes hydraulic power units to generate pressure during operation, which drives the hydraulic oil cylinder as the main power to raise and lower the lifting cargo elevator platform. When a guide rail type hydraulic lifting cargo elevator malfunctions, it can immediately stop running, with high safety and stability. The driving of the hydraulic power unit makes it have strong load-bearing capacity and smooth lifting, which can achieve the transportation of large tonnage goods
The safety control voltage of 18 is selected with rolling guide shoes, high accuracy, wear resistance, and stable lifting. The characteristics of the Jinchuang lifting platform are as follows: 1. There is no need for a machine room above the shaft. 2. The hydraulic elevator is not equipped with a counterweight device to improve the utilization rate of the shaft area. 3. The load and load cylinder of the hydraulic elevator directly act on the foundation pit, and the strength requirements of the shaft are low, Brick or brick concrete structure hoistway can be used for Jinchuang lifting platform safety and stability advantages. Overflow valve: It can prevent system pressure from being too high during upward movement. Emergency manual valve: In case of power failure, mainly used for high-altitude cargo transportation between floors. With a load capacity of 1-50 tons and an elevation of 1-25 meters, guide rail elevators also known as hydraulic elevators, can be installed indoors and outdoors. They have a high lifting height and use side mounted oil cylinders, ensuring smooth operation, low noise, convenient maintenance, manual emergency descent can be used, which is safe, convenient,MessinaAluminum alloy lifting platform double columns, fast, and practical. The pit depth is generally 15cm-30cm. Professional elevator manufacturers have high pressure resistance, good waterproof performance and fire and high temperature resistance, Strong overload capacity corrosion resistance, radiation resistance, long service life. The top layer height is not affected, and can be customized according to the on-site environment. It is suitable for 2-3 story steel structures or concrete factories, and can be used both internally and externally.
Drivers should be responsible for supervising the uniform distribution of items transported by the platform on the platform as much as possible to prevent partial loading and prohibit overloading. flat
The lifting foundation of the platform is a large structural component made of alloy steel plates with different thicknesses that are welded together. The welding amount is large the structural shape is complex, and residual stress is inevitably generated during the manufacturing process. In order to prevent deformation of the components due to changes in residual stress during use, it is necessary to perform stress relief treatment on the completed components.

Installation material list.Whether the vibration aging treatment has achieved the results can be judged based on the parameter curve observation method.
Lifting and lowering
The selection of vibration pickup points refers to the placement point of the sensor,MessinaAluminum alloy lifting platform, which is used to measure the vibration amplitude of the workpiece. According to GB/T25712-2010, the acceleration sensor should be placed on the workpiece with a certain rigidity and a large amplitude, and its testing direction should be adjusted to be perpendicular to the plane where the effective zone of the vibration mode is located. Considering the complex structure of the lifting foundation workpiece and the uneven thickness of each component, the vibration pickup point is set in a thick area in the middle of the component.
Messina.The vibration frequency should be set to obtain large dynamic stress with low energy consumption, and the resonance frequency should be used to handle time dependent vibration. However, there may be one or more resonance peaks in large components, and using resonance peaks with higher peaks and lower frequencies for aging can achieve optimal results. The resonance frequency needs to be determined by trial vibration, which slowly increases the speed of the excitation motor from 0, and determines the relationship curve between the amplitude of the workpiece and the motor speed to determine the resonance point of the workpiece. According to the scanning curve, a large acceleration was obtained at 5366r/min,MessinaAluminum alloy elevator platform, and the layout principle is: when the aspect ratio of the component is greater than 2, two point supports can be used; When the aspect ratio is close to 1, it is advisable to use or 4-point support.
