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.
Ostholt.When loosening occurs, newly processed and assembled components have deviations in geometric shape and fitting dimensions. In the early stages of use, due to alternating loads such as impact and vibration, as well as factors such as heat and deformation, coupled with rapid wear and tear, it is easy to cause the previously fastened components to loosen.
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.
.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.
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 driver shall close and lock the movable doors at both ends of the protective fence before work, 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 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.
Many times after installing hydraulic cargo elevators in factories, floors, docks, and other places, there may be some adverse reactions and problems in the early stage. Below,OstholtSelf-propelled lifting platform, Yakali's editor summarizes some common problems with hydraulic cargo elevators and provides some statements on how to solve and prevent these problems.
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, also known as hydraulic elevators, can be installed indoors and outdoors. They have a high lifting height and use side mounted oil cylinders,OstholtMobile lifting platform, 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, 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.
Quotation sheet.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.

The curved arm lifting platform adopts a curved arm working arm, 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.

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), simple and reliable operation stable equipment 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, 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,OstholtScissor fork mobile hydraulic lifting platform, 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.
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.
