Cannes ScissorThe 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,Cannes Mobile loading and unloading 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.

Cannes .How to maintain and maintain the stage? When using the lifting stage in daily life, attention should be paid to maintenance to extend its lifespan. Below, Jinan Dasheng Hydraulic Machinery will introduce several maintenance and attention points for everyone: the brakes of each mechanism should be regularly inspected and adjusted for the clearance between the brake pads and wheels to ensure flexibility and reliability. On the friction surface, there should be no dirt present, and any dirt must be washed off with gasoline or thinner. Pay attention to checking each steel wire rope for broken wires and loose strands. If it exceeds the relevant regulations, it must be replaced immediately. Professional elevator manufacturers have a complete range of products, which are popular both domestically and internationally. Our equipment has a long service life! The industry leader in product wire products, welcome to inquire
The selection of vibration pickup points refers to the placement point of the sensor, 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.
.Whether the vibration aging treatment has achieved the results can be judged based on the parameter curve observation method.
Outdoor guide rail lifting platform, 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, and long service life. In case of power failure, manual emergency descent can be used, which is safe, convenient, fast,Cannes Four wheel mobile scissor fork lifting platform, 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.
Emergency stop: Press the emergency button switch to raise or lower the machine.

Please refer to the instruction manual for the maintenance and maintenance of the elevator to check the braking torque of the brake
According to calculations, when the support points of the beam type components are located along the length of 1/9L on both sides the vibration resistance is relatively small, making it easy to obtain resonance and vibration effects with larger amplitudes. The geometric shape of the structure on the lifting foundation is similar to a long beam type component,Cannes Rail guide rail type lifting platform, and the structure is complex. Therefore, two support points should be taken on each side for time treatment.
Customer first.Power supply voltage: Motor power: Lifting: Rocker self reset switch operation Overload protection: Over current relay.
Outbound call form: Outbound call boxes are pre embedded or installed in a column style on the wall or ground near the parking floor above and below the platform, and are linked to operate the platform up and down.
Jinchuang lifting platform product feature 01 is mainly used for high-altitude cargo transportation between floors. With a load capacity of 1-50 tons and a lifting height of 1-25 meters, a guide rail elevator, also known as a hydraulic elevator, can be installed indoors and outdoors. The lifting height is high and uses a side mounted oil cylinder, which runs smoothly, has low noise, is convenient for maintenance, and has a long service life. In case of a power outage, manual emergency descent can be used, which is safe, fast, and practical. The pit depth is generally 15cm-30cm, and the top layer height is not affected The 04 pump station can be customized according to the on-site environment, suitable for 2-3 floors of steel structures or concrete factories. Both the internal and external parts can be used. The 05 pump station adopts a joint venture pump station and an imported pump station from Italy.

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, so 5366r/min was determined as the aging frequency.
safety requirements .The second method is the protective layer method, which covers the metal surface of the aluminum alloy lifting platform with a protective layer to isolate the metal products from the surrounding corrosive medium and prevent corrosion. Apply engine oil, petroleum jelly, paint, or cover the surface of steel parts with corrosion-resistant non-metallic materials such as enamel and plastic; Using electroplating, spray plating, etc., to coat the surface of steel with a layer that is not easily corroded
With the continuous development of the economy, meeting the needs of society, and increasing productivity, hydraulic cargo elevators play an important role in high-altitude operations. Hydraulic cargo elevators operate up and down, when the support points of the beam type components are located along the length of 1/9L on both sides, the vibration resistance is relatively small, making it easy to obtain resonance and vibration effects with larger amplitudes. The geometric shape of the structure on the lifting foundation is similar to a long beam type component and the structure is complex. Therefore, two support points should be taken on each side for time treatment.
Cannes .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?
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.
However, large weight, large differences in residual stress size and distribution, it is crucial to develop a reasonable process. Therefore, they found Nanjing Juhang and our JH-700 vibration aging equipment, and requested us to develop a complete vibration aging process.
