the safety net below immediately stops running and descends when encountering obstacles.
Yongji.Check if the usage period of the speed limiter has expired. If it exceeds the usage period, it is necessary to send it to a qualified professional unit for inspection and calibration. What are the functions of the lifting stage device?
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,YongjiMobile boarding bridge, which is safe, convenient, fast, and practical.

Beautiful appearance, easy operation, visual display of the position of the elevator car on the floor wiring harness connected using connectors, with automatic and manual options.
.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.
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, etc., to coat the surface of steel with a layer that is not easily corroded
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 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, hot plating,YongjiMobile loading and unloading platform, spray plating, etc., to coat the surface of steel with a layer that is not easily corroded
Since the antirust paint on the exterior layer will actively react with the oxygen in the air, the reaction speed will be accelerated, so the exterior paint on the warehouse goods elevator will show signs of aging and then fall off every once in a while. Therefore, when maintaining the equipment of the lift table at ordinary times, pay attention to its storage, and try not to leave it outdoors, let alone in cool days or rainstorm
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!
Quality inspection report.Applicable environment: Indoor or outdoor Applicable temperature: Safety device Safety rocker: When the equipment is running and rising, the rocker will automatically prevent wheelchair platform.
Power supply voltage: Motor power: Lifting: Rocker self reset switch operation Overload protection: Over current relay.
The 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.
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, they found Nanjing Juhang and our JH-700 vibration aging equipment, and requested us to develop a complete vibration aging process.
Inspection environment.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 protective cable condition of the cable guide frame
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.
Yongji.02 The lifting platform adopts a fully hydraulic lifting mechanism, which can be operated inside the platform bucket and on the elevator body. 03 The working arm of the lifting platform can rotate 360 degrees. 04 The hydraulic system is equipped with a safety valve to prevent the main arm oil cylinder oil pipe from cracking. 05 The hydraulic legs are equipped with a hydraulic locking device to prevent the leg oil cylinder from retracting. 06 The hydraulic system is equipped with an automatic platform overload protection device, In order to ensure the safety of operators, each section of the working arm on the platform 07 is equipped with safety limit devices.

The 11 folding arm lifting platform product can also use a 50Hz, 380V power motor, and diesel engine dual power.
The arrangement of vibration points should be based on the vibration aging process standard GB/T25712-20. The vibration aging exciter should be placed at a position with high rigidity and amplitude of the workpiece, and its rotating axis should be parallel to the plane where the effective zone of the vibration mode is located. The exciter should be fixed at the end angle or edge of the workpiece with high rigidity so that small energy can be used to excite the component with large amplitude. Based on the structural shape of the foundation, we set the vibration points on the protruding plates on each side of the workpiece.
