The cleaning oil for the hydraulic system must use hydraulic oil of the same brand as the system used, fully drain the system while the oil is hot.Many times, after installing hydraulic cargo elevators in factories, floors, docks, and other places, Yakali's editor summarizes some common problems with hydraulic cargo elevators and provides some statements on how to solve and prevent these problems.Foggia,The safety control voltage of is selected with rolling guide shoes, high accuracy, 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, 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 can make the elevator emergency descend to the nearest floor position and open the door.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.Ajax,Ensure that power cables and electrical circuits are not damagedCheck the relative orientation between the cable support wall and the cable guide frameWhen disassembling the hydraulic oil tank filler cap, inspection hole, hydraulic oil pipe and other parts, it is necessary to avoid dust during the system oil passage. The disassembled parts must be thoroughly cleaned before opening. When disassembling the hydraulic oil tank filler cap, 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, 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, clean the filter at the same time. Before installing the filter element it may also be unclean). When changing the oil, carefully clean the bottom dirt inside the filter housing with materials.

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. 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. The interference and hazard analysis of the frequency conversion speed regulation construction elevator circuit is becoming increasingly widespread in the development of technology today. Variable frequency speed regulation has the characteristics of stable start and stop process, reducing mechanical shock, increasing the comfort of passengers, and improving the service life. At the same time it can also change the speed of power supply frequency regulation, save electric energy and improve work efficiency. However, there will be interference in the use of variable frequency speed regulation system, which will often cause safety accidents of construction elevator.Vibration aging treatment and effect judgment: According to the aging process plan, after setting the support points and vibration pickup points of the workpiece, use a rigid fixture to fix the exciter on the workpiece, and use the manual function of the equipment to test the vibration. It is determined that around revolutions is the resonance frequency of the component. The amplitude generated by the eccentric gear of the exciter in the fourth gear can meet the vibration processing requirements of the foundation seat, so the excitation force is selected as the fourth gear.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 membersWhich one is better,Check the interlocking equipment, up and down travel, and other safety maintenance switches of the cage door and fence doorThe wear rate is fast, and due to factors such as processing, assembly, and adjustment of new machine components, the friction surface is rough,FoggiaLarge mobile lifting platform, 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,Foggia12 meter mobile 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.Monthly maintenance: View weekly inspection items

Check the clearance of the ball bearing and the wear of the suspension wheel guide wheel. If the roller is worn, it is necessary to adjust or replace it. If the elevator bearing is worn, replace the guide wheel or bearingRecommendation and consultation,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?Outbound call form: Outbound call boxes are pre embedded or installed in a column style on the wall or ground near the parking floor above and below the platform, and are linked to operate the platform up and down.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, Yakali's editor summarizes some common problems with hydraulic cargo elevators and provides some statements on how to solve and prevent these problems.Foggia,　　?? 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,FoggiaAluminum alloy elevator platform, and carefully inspect the steel structure, safety protection devices, electrical devices, and transmission devices of construction elevatorsQuarterly maintenance: Check the items checked each monthCheck and repair the electrical circuit and control panel switch components.
