TianjinStage style lifting platformWhat are the reasons for the fast wear

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.

During aging treatment, the equipment prints the vibration aging curve online. According to the curve, the front end of the a-t curve shows an upward trend, indicating that the damping inside the component decreases after vibration treatment, so the amplitude gradually increases; Since then, indicating that the structure of molecules inside the component tends to be stable, which conforms to the judgment standard of curve observation strip, thus it can be determined that the workpiece has reached the effect. The precautions for using an electric lifting platform are as follows: the user unit should arrange a dedicated person to operate the lifting platform and develop details and safety precautions for the use of the lifting platform based on their own unit's situation, and hang it in a prominent position. When working on an electric lifting platform, professional drivers and operators must be equipped, and they must undergo specialized training and be qualified. They must hold relevant certificates and take on corresponding responsibilities according to the actual situation of the work. After the construction is completed the lifting platform needs to be moved on the site and should be operated by a professional driver. Before daily work, zy12 drivers must carefully check the electrical, hydraulic, and mechanical systems of the platform, check the working range of the lifting platform truck, and remove obstacles that hinder the rotation and walking of the lifting platform truck. And empty the platform up and down several times to check for any faults or abnormal phenomena. It is also necessary to pay attention to the accuracy of the platform platform landing station for any obvious abnormal differences. Professional improvement of quality assurance for aircraft manufacturers. The promotional activity is ongoing and new and old customers are welcome to come for consultation

Tianjin.Check the relative orientation between the cable support wall and the cable guide frame

However, large welded structural components have the characteristics of complex morphology, 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,TianjinSelf propelled platform lifting, and requested us to develop a complete vibration aging process.

.Thermal aging stress relief is generally suitable for small workpieces, while the lifting foundation structure has a large volume and does not have a large enough annealing furnace. Using natural aging takes one year and the production cycle is too long, so neither of these two methods is feasible. After research and understanding by the manufacturer, it was found that selecting appropriate support points for large welded structural components can perform vibration aging stress relief. Therefore, the manufacturer has decided to use vibration aging for stress relief of the platform lifting foundation. Long term promotion of downgrading manufacturers, 20 year old brand, with price advantages and guaranteed quality!

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

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.

Manganese steel is generally used as the primary profile for warehouse cargo elevators. In order to achieve better anti-corrosion effect, a layer of rust resistant primer is usually applied, which effectively blocks air and prevents premature corrosion of the steel. Below, Ruilong hydraulic press will explain the role of rust resistant primer.

According to GB/T25712-2010,TianjinSelf propelled mobile lifting platform, 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, and then flattens; The resonance frequency of the a-n curve after vibration is lower than that before vibration; The bandwidth of the a-n curve after vibration narrows compared to before vibration; The resonance peak of the a-n curve after vibration exhibits fission phenomenon; The curve flattens out after descent.

Highly recommended.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, hot plating, spray plating, etc., to coat the surface of steel with a layer that is not easily corroded

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,TianjinMobile loading and unloading platform, two support points should be taken on each side for time treatment.

When the lifting base plate descends, the safety net below immediately stops running and descends when encountering obstacles.

offer.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.

Check the oil level of the gearbox and make up for new oil if necessary

Whether the vibration aging treatment has achieved the results can be judged based on the parameter curve observation method.

Tianjin.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.
