According to GB/T25712-2010, when one of the following situations occurs in the curve related to the aging frequency, it can be determined that the area covered by the effective zone of the vibration mode at that frequency has reached the aging effect: the curve rises and flattens; The curve rises, then falls, it is necessary to start from the source. The current technology is relatively advanced. When manufacturing aluminum alloy lifting platforms, which steel should be chosen for production? Because there are many corrosion-resistant steel materials now, adding chromium, nickel, etc. to ordinary steel to make stainless steel, changing the internal structure of the metal to prevent rust.
Malapi.Transfer of goods between floors of rooms, restaurants, and restaurants. The low height is between 150-300mm, especially suitable for workplaces that cannot excavate pits. And there is no need for upper lifting points, with diverse forms (single column, double column, four column), stable equipment operation, simple and reliable operation, economic and convenient goods transmission, and difficult to solve narrow spaces that cannot reach the requirements. A customized delivery platform can be created, and the product hydraulic system is equipped with anti fall, upper and lower door interaction and operation buttons can be set on each floor and lifting platform workbench to achieve multi-point. The product has a sturdy structure, a large load-bearing capacity, smooth lifting, simple and convenient installation and maintenance, making it an ideal and economical cargo conveying equipment for replacing elevators between low floors. The lifting stage device is mainly responsible for data processing of the operation mechanism and work bar of the vehicle, calculating the safety area of the lifting stage, and is suitable for the electric control system of the self lifting stage lifting platform. The main sensors in the electric control system include angle sensors, long angle sensors, dual axis inclination sensors, and energy saving of the oil cylinder system.
Whether the vibration aging treatment has achieved the results can be judged based on the parameter curve observation method.
.Low failure rate: Due to the use of advanced hydraulic systems and good methods, the failure rate of elevator operation can be minimized. Low power consumption: When the hydraulic elevator descends, it is driven by the pressure generated by its own weight, which greatly saves energy.
Emergency stop: Press the emergency button switch to raise or lower the machine.

However, large welded structural components have the characteristics of complex morphology, large weight, large differences in residual stress size and distribution, and it is difficult to achieve good results using ordinary vibration aging technology. Therefore, it is crucial to develop a reasonable process. Therefore, and requested us to develop a complete vibration aging process.
Quarterly maintenance: Check the items checked each month
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, and the structure is complex. Therefore, two support points should be taken on each side for time treatment.
Sales Department.Firstly, it is necessary to start from the source. The current technology is relatively advanced. When manufacturing aluminum alloy lifting platforms, which steel should be chosen for production? Because there are many corrosion-resistant steel materials now, adding chromium, nickel, etc. to ordinary steel to make stainless steel, changing the internal structure of the metal to prevent rust.
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.
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.

The reduction gearbox, gearbox, external meshing gear and other parts, as well as the hydraulic oil, 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,MalapiGuide rail type lifting platform, 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.
Malapi.Firstly, it is necessary to start from the source. The current technology is relatively advanced. When manufacturing aluminum alloy lifting platforms, which steel should be chosen for production? Because there are many corrosion-resistant steel materials now,Malapi10 ton mobile boarding bridge manufacturer, adding chromium, nickel, etc. to ordinary steel to make stainless steel, changing the internal structure of the metal to prevent rust.
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,MalapiPrice of 10 ton mobile boarding bridge, a large acceleration was obtained at 5366r/min, 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.
