Outdoor guide rail lifting platform,PalmaSelf propelled tracked scissor fork 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, 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.

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.

Palma.The lifting stage can provide real-time information on the operation of the entire vehicle, avoiding relying solely on the experience of operators to coordinate with each other, and improving the reliability and safety of the system. The definition of safety zone is very important because the lifting stage has a large range of movements, and it must be accurately calculated. The lifting stage has two structurally separate systems, the ground turntable and the high-altitude work bar. However, for various movements on the vehicle, which needs to consider the priority of operation, system redundancy, and safety assurance of actions.

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.

.However, large welded structural components have the characteristics of complex morphology, large weight, 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.

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!

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.

Emergency descent: Handle operation or use of manual pressure relief and activation of emergency battery system to implement emergency descent function safety net.

On the contrary, it should be adjusted in the opposite direction; When the meshing backlash of the gear pair is greater than 0.5mm, loosen the connecting nut of the eccentric shaft of the guide roller 4 and the tooth back pressure wheel as shown in 2, adjust the tooth back pressure wheel to press towards the back plane of the gear rack until the backlash reaches a reasonable range. Otherwise, it should be adjusted in the opposite direction. At this point, the guide roller should be loosened for 2 o and then adjusted according to the adjustment of the guide roller.

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.

Free consultation.According to GB/T25712-2010, when one of the following situations occurs in the curve related to the aging frequency, 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.

Heavy load capacity: protective plate form: 90° Or 180° Interchangeable configuration rocker working angle: 75° Drive method: hydraulic power unit drive or screw drive.

The second method is the protective layer method then falls, 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

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.
