Hydraulic cargo elevators operate up and down and can provide us with a safe and stable platform. We can provide security for our safety when working at heights.Baltimore,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,BaltimoreMobile boarding bridge, it is crucial to develop a reasonable process. Therefore, they found Nanjing Juhang and our JH- vibration aging equipment, and requested us to develop a complete vibration aging process.The wear rate is fast, and due to factors such as processing assembly, and adjustment of new machine components, the friction surface is rough the mating surface area is small, the concave and convex parts on the surface of the parts are intertwined and rubbed against each other. The metal debris that falls off from the grinding process, in turn, acts as abrasive and continues to participate in friction, further accelerating the wear of the mating surface of the parts. Therefore, during the running-in period, it is easy to cause wear on components (especially the mating surface), with a fast wear rate. At this point, if overloaded, it may cause damage to the components and lead to early failures.Penza,BaltimoreFour pillar aluminum alloy lifting platform,Regularly check all wires and cables for damage. Timely bandage and replace damaged parts.When loosening occurs, 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.Please refer to the instruction manual for the maintenance and maintenance of the elevator to check the braking torque of the brake

We can provide security for our safety when working at heights.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,BaltimoreDouble column aluminum alloy lifting platform, or cover the surface of steel parts with corrosion-resistant non-metallic materials such as enamel and plastic; It is not easy to apply a layer of electroplating, hot plating, spray plating, etc. on the surface of steelCheck if the orientation of the upper and lower limit blocks on the guide rail frame is correcthow much,The frequency conversion system circuit of the construction elevator is mainly composed of two parts: the main circuit and the circuit. The main circuit is mainly composed of a construction lifting cargo elevator (hereinafter referred to as the lifting cargo elevator) driven by a more complex rectifier. Before installation, all the eccentric roller shafts of the lifting cage and driving mechanism are loosened or adjusted to a large eccentricity. The lifting cage and driving mechanism are installed in the guide rail frame respectively, and the two are connected. Starting from adjusting the driving mechanism, power on the suspension cage to lift it m above the ground or detach it from the ground buffer spring (or support). The adjustment and sequence are as follows: . Use a special wrench to rotate the lower double (single) pendulum eccentric shaft to adjust the eccentricity to ensure that the installation plate surface of the driving mechanism is perpendicular to the horizontal plane, and ensure that the upper and lower pendulum wheels evenly guide the rails at the same time. Use your hand to move each wheel body and check if it evenly presses the rails; . Use a special wrench to rotate the eccentric shaft of the gear rack back pressure wheel to adjust the side clearance during gear rack meshing. When adjusting, each pressing wheel should evenly press on the back of the rack. Move each wheel body by hand to check if it evenly presses against the tooth back. Similarly, adjust the guide rollers on both sides of the guide rail. The adjustment key is to adjust the guide wheel on one side of the guide rail to lightly press it onto the guide rail. When moving the wheel body by hand, it should be possible to rotate but there should be obvious obstruction; The roller on the other side should maintain a clearance of .-. ram with the guide rail; . Adjust the lifting cage according to the above and sequence. If the driving mechanism and the lifting cage are integrated into the lifting cargo elevator, the lifting cage should be adjusted according to the and sequence of adjusting the driving mechanism. Conduct a visual inspection of the operation of each roller, and use the lead pressing method and coloring method to check the meshing of the gear pair; Fine tune pairs of unsatisfactory parts. The key point is to carefully adjust the meshing status of the gear pair: when the spots shown in appear on the surface of the gear rack, it indicates that the driving mechanism is tilted towards the side of the guide rail. At this time, the lower swing wheel (single or double wheel) should be adjusted to move the lower part of the driving mechanism towards the direction of the guide rail until the area of the spots reaches more than % of the surface of the gear rack. The smaller the area, the easier it is to damage the gears and racks.Leakage occurs due to looseness, vibration, but due to vibration and impact during the operation process processing and other defects are difficult to detect during assembly and debugging, these defects are exposed, manifested as oil (water) leakage. Therefore, leakage is prone to occur during the running-in period. Poor, due to the small fit clearance of newly assembled components and the difficulty in ensuring the uniformity of fit clearance due to assembly and other reasons, oil (grease) is not easy to form a uniform oil film on the friction surface to prevent wear. This reduces efficiency and causes early abnormal wear of the components. In severe cases, it can cause scratches or bite on the friction surface of precision fitting, leading to the occurrence of faults.Use a feeler gauge to check the wear condition of the worm gear of the worm gear reducer. Please refer to the instruction manual for specific requirements

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?Total quality management,Check the safety interlocking equipment of the first cut door of the hanging cageThe 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 , two point supports can be used; When the aspect ratio is close to , it is advisable to use or -point support.The lifting stage is a high-altitude operation equipment, and prolonged use can cause loose connections between some components. So in order to ensure the personal safety of construction workers, it is necessary to regularly inspect the lifting stage and tighten any loose components.
