Manganese steel is generally used as the primary profile for warehouse cargo elevators. In order to achieve better anti-corrosion effect, a layer of rust resistant primer is usually applied, which effectively blocks air and prevents premature corrosion of the steel. Below, Ruilong hydraulic press will explain the role of rust resistant primer.Attention: Abnormal meshing of gear teeth should be avoided: uneven rolling of the rollers should be avoided; Avoid diagonal orientation of the guide rollers; It should be avoided that the guide rollers are kept at the same time for a long time; The above abnormal phenomena can lead to rapid wear and even scrapping of gears, racks, rollers and guide rails. If adjusted more carefully,Emergency descent: Handle operation or use of manual pressure relief and activation of emergency battery system to implement emergency descent function safety net.The reduction gearbox it will be more beneficial for the service life of the elevator.Hartwan, gearbox, external meshing gear and other parts, as well as the hydraulic oil, are all carried out according to the requirements in the table.Larvik,Many times, after installing hydraulic cargo elevators in factories, docks, and other places, there may be some adverse reactions and problems in the early stage. Below, Yakali's editor summarizes some common problems with hydraulic cargo elevators and provides some statements on how to solve and prevent these problems.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 oilCheck the wear condition of the pinion and rack, please refer to the instruction manual for specific requirements

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, 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,HartwanFour pillar aluminum alloy lifting platform, 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.The safety control voltage of is selected with rolling guide shoes, wear resistance, and stable lifting. The characteristics of the Jinchuang lifting platform are as follows: . There is no need for a machine room above the shaft. . The hydraulic elevator is not equipped with a counterweight device to improve the utilization rate of the shaft area. . The load and load cylinder of the hydraulic elevator directly act on the foundation pit, and the strength requirements of the shaft are low Brick or brick concrete structure hoistway can be used for Jinchuang lifting platform safety and stability advantages. Overflow valve: It can prevent system pressure from being too high during upward movement. Emergency manual valve: In case of power failure, it is necessary to adjust or replace it. If the elevator bearing is worn, replace the guide wheel or bearingPursuit of excellence,Regarding the construction elevator with counterweight, check the adjustment and fixation status of the counterweight guide wheel. Check the balancing equipment of the steel wire rope, the crown wheel and the counterweight steel wire rope bracketWeekly maintenance: According to the operation instructions, ensure that the elevator is inspected and smooth every day　　?? Hidden danger investigation relies on joint efforts from all aspects:?? Construction enterprises are the main responsibility for identifying hidden dangers in construction elevators. They should strengthen daily inspections and regular inspections, and carefully inspect the steel structure, safety protection devices, electrical devices, and transmission devices of construction elevators

Leakage occurs due to looseness, vibration, and the influence of heat on the sealing surface and pipe joints of the machine; Some casting, 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,Hartwan8-ton mobile boarding bridge, 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.Inspection items,Regularly check all wires and cables for damage. Timely bandage and replace damaged parts.During aging treatment, the equipment prints the vibration aging curve online. According to the curve, indicating that the damping inside the component decreases after vibration treatment, so the amplitude gradually increases; Since then, the amplitude change has been basically stable, indicating that the structure of molecules inside the component tends to be stable, thus it can be determined that the workpiece has reached the effect. The precautions for using an electric lifting platform are as follows: the user unit should arrange a dedicated person to operate the lifting platform and develop details and safety precautions for the use of the lifting platform based on their own unit's situation, and hang it in a prominent position. When working on an electric lifting platform, professional drivers and operators must be equipped, and they must undergo specialized training and be qualified. They must hold relevant certificates and take on corresponding responsibilities according to the actual situation of the work. After the construction is completed, the lifting platform needs to be moved on the site and should be operated by a professional driver. Before daily work, zy drivers must carefully check the electrical, hydraulic, and mechanical systems of the platform, check the working range of the lifting platform truck, and remove obstacles that hinder the rotation and walking of the lifting platform truck. And empty the platform up and down several times to check for any faults or abnormal phenomena. It is also necessary to pay attention to the accuracy of the platform platform landing station for any obvious abnormal differences. Professional improvement of quality assurance for aircraft manufacturers. The promotional activity is ongoing,HartwanHydraulic boarding bridge mobile manufacturer, and new and old customers are welcome to come for consultationUse 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 requirementsHartwan,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, it is also an interconnected system, which needs to consider the priority of operation, system redundancy, and safety assurance of actions.Regarding the construction elevator with counterweight, check the adjustment and fixation status of the counterweight guide wheel. Check the balancing equipment of the steel wire rope, the crown wheel, and the counterweight steel wire rope bracketThe 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, and the surface pressure condition is uneven.
