Check and repair the electrical circuit and control panel switch components. If there is aging in the circuit, replace itCheck the safety interlocking equipment of the first cut door of the hanging cageRostock,Firstly, 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.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, use a feeler gauge to measure the side clearance to .; Between .mm, 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,Regularly check the connection of each part and tighten it if there is any looseness. The tightness of the body connecting bolts should be checked when the body is under pressure (the rotating arm can be used to cause compression)Check if the orientation of the upper and lower limit blocks on the guide rail frame is correctCheck the clearance of the ball bearing and the wear of the suspension wheel guide wheel. If the roller is worn the easier it is to damage the gears and racks.Bouna, it is necessary to adjust or replace it. If the elevator bearing is worn, the rocker will automatically prevent wheelchair platform.Organize, remove rust and repaint the structural components such as the suspension cage and guide rail frame for corrosion, and reinforce the severely corroded load-bearing membersInspection standard,The reduction gearbox gearbox, external meshing gear and other parts, as well as the hydraulic oil, are all carried out according to the requirements in the table.On the contrary, it should be adjusted in the opposite direction; When the meshing backlash of the gear pair is greater than .mm, loosen the connecting nut of the eccentric shaft of the guide roller and the tooth back pressure wheel as shown in , adjust the tooth back pressure wheel to press towards the back plane of the gear rack until the backlash reaches a reasonable range. Otherwise, the guide roller should be loosened for o and then adjusted according to the adjustment of the guide roller.　　

The surface of each part of the brush should be kept clean, and the brush pressure should be adjusted to ensure that its area is not less than %.resources,Leakage occurs due to looseness, vibration, and the influence of heat on the sealing surface and pipe joints of the machine; Some casting,RostockAluminum alloy double column lifting platform, processing and other defects are difficult to detect during assembly and debugging, but due to vibration and impact during the operation process, 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.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,RostockPrice of Mobile Scissor Fork Lifting Platform, 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.Check the wear and clearance condition of the guide wheel of the cargo elevatorRostock,A non scissor type hydraulic lifting mechanical equipment used for transporting goods between floors of industrial factories, restaurants, environmentally friendly,RostockSelf propelled curved arm lifting platform, and economical!
