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 elevatorsThe 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,Hel BrownScissor fork type mobile lifting platform, 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.When disassembling the hydraulic oil tank filler cap, filter cover 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, 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.

Check the protective cable condition of the cable guide frameDuring aging treatment, indicating that the damping inside the component decreases after vibration treatment the front end of the a-t curve shows an upward trend, so the amplitude gradually increases; Since then, indicating that the structure of molecules inside the component tends to be stable, which conforms to the judgment standard of curve observation strip, 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,Hel BrownMobile scissor fork lifting platform, 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, and new and old customers are welcome to come for consultationDrop 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,All connecting shafts must have split pins and be sufficient.Check the wear and clearance condition of the guide wheel of the cargo elevatorCheck the wear and clearance condition of the guide wheel of the cargo elevator

Check the protective cable condition of the cable guide frameSupply chain quality management,After cleaning, clean the filter and replace it with a new filter element before adding new oil. What adverse reactions may occur during the early use of hydraulic cargo elevators?The 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,Hel BrownCar mounted aluminum alloy lifting platform, 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.Check the relative orientation between the cable support wall and the cable guide frameHel Brown,Check the wear condition of the pinion and rack, please refer to the instruction manual for specific requirements　　?? When the construction supervisory department fulfills its safety supervision and inspection responsibilities, it shall order the immediate elimination of potential safety hazards in the production of construction elevators and cargo elevators discovered during the inspection. If safety cannot be guaranteed before or during the elimination of major production safety hazards, it shall be ordered to evacuate workers from the hazardous area or temporarily stop construction. In the work of hazard investigation and control, the investigation shall be serious, the rectification shall be resolute, and the results shall be consolidated.Quarterly maintenance: Check the items checked each month
