Check the protective cable condition of the cable guide frameOn 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, it should be adjusted in the opposite direction. At this point, the guide roller should be loosened for o and then adjusted according to the adjustment of the guide roller.Huanghua,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, 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.Drop test to check if the braking interval of the safety governor meets the requirements of the rules. Equipment transfer maintenance: Check the coupling between the electric motor and the worm gear reducer, and dismantle the gearbox. Clean all components and seals replace excessively worn and deformed parts and smooth oilLeribe,Adjust and correct various safety doors and mechanical interlocking equipmentCheck and repair the electrical circuit and control panel switch components. If there is aging in the circuit, replace itWhen disassembling the hydraulic oil tank filler cap, filter cover, inspection hole, hydraulic oil pipe and other parts, first remove the soil around the tank cap. After loosening the tank cap, remove any remaining debris from the joint area (do not rinse with water to prevent water from seeping into the tank). Only after confirming cleanliness can the tank cap be opened. When using materials and hammers, materials that do not remove fiber impurities and specialized hammers with rubber attached to the surface should be selected. Hydraulic components and hydraulic hoses should be carefully cleaned, dried with high-pressure air, and then assembled. Choose a well packaged filter element (the inner packaging is damaged, although the filter element is intact, it may also be unclean). When changing the oil, clean the filter at the same time. Before installing the filter element, carefully clean the bottom dirt inside the filter housing with materials.

The wear rate is fast, and due to factors such as processing,HuanghuaPrice of Mobile Scissor Fork Lifting Platform, assembly and adjustment of new machine components, the friction surface is rough, the mating surface area is small, and the surface pressure condition is uneven. During the operation of the machine, 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.Emergency descent: Handle operation or use of manual pressure relief and activation of emergency battery system to implement emergency descent function safety net.Check the oil level of the gearbox and make up for new oil if necessaryAdministration,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, the easier it is to damage the gears and racks.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 membersCheck the interlocking equipment, up and down travel, and other safety maintenance switches of the cage door and fence door

Ensure that power cables and electrical circuits are not damagedMeticulous workmanship,The wear rate is fast, and due to factors such as processing, assembly, and adjustment of new machine components, the mating surface area is small, and the surface pressure condition is uneven. During the operation of the machine, 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,HuanghuaLarge fixed lifting platform, with a fast wear rate. At this point, if overloaded, it may cause damage to the components and lead to early failures.According to GB/T- when one of the following situations occurs in the curve related to the aging frequency, it can be determined that the area covered by the effective zone of the vibration mode at that frequency has reached the aging effect: the curve rises and flattens; The curve rises, then falls, 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.On the contrary it should be adjusted in the opposite direction; When the meshing backlash of the gear pair is greater than .mm,HuanghuaCurved arm lifting platform, 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, it should be adjusted in the opposite direction. At this point, the guide roller should be loosened for o and then adjusted according to the adjustment of the guide roller.Huanghua, and if any potential production safety accidents are found, it shall require the installation unit and the user unit to rectify within a specified period of time. If the installation unit and the user unit refuse to rectify they shall promptly report to the construction unit
