?? 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.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, 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.Hejian,The selection of vibration pickup points refers to the placement point of the sensor, which is used to measure the vibration amplitude of the workpiece. According to GB/T-, the acceleration sensor should be placed on the workpiece with a certain rigidity and a large amplitude, and its testing direction should be adjusted to be perpendicular to the plane where the effective zone of the vibration mode is located. Considering the complex structure of the lifting foundation workpiece and the uneven thickness of each component, the vibration pickup point is set in a thick area in the middle of the component.Check the wear and clearance condition of the guide wheel of the cargo elevatorLuninyets,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 it will be more beneficial for the service life of the elevator.　　?? 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 elevatorsDrop 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 oil

Every customer pays attention to the price of elevators, so how does the manufacturer calculate the price of elevators? In general, the manufacturer calculates the price of the elevator for customers based on the actual size, height, and carrying capacity of the on-site reserved opening provided by the customer Customers do not need to pay too much attention to the price difference between different elevator manufacturers when purchasing elevators, as the different materials used, material brands, and production processes result in different prices for elevators Customers can consider the cost-effectiveness of elevators more when purchasing, it should be immediately stopped from use. After eliminating the malfunction and accident hazards, it can be put back into useDuring aging treatment, the equipment prints the vibration aging curve online. According to the curve,HejianCrawler folding arm lifting platform, the front end of the a-t curve shows an upward trend, 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, 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, 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, avoiding relying solely on the experience of operators to coordinate with each other, and it must be accurately calculated. The lifting stage has two structurally separate systems, 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.original,Check the protective cable condition of the cable guide frameCheck 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?Check the wear condition of the pinion and rack, please refer to the instruction manual for specific requirements

　　?? The supervision unit shall effectively fulfill its safety responsibilities, 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 unitRespect for customers,There are many operational errors, and due to insufficient understanding of the structure and performance of the machine (especially for new operators), it is easy to cause malfunctions and even mechanical accidents due to operational errors. How to calculate the lifting cargo elevator? A lifting cargo elevator is a heavy lifting mechanical equipment that can manually operate the system's buttons to complete the transportation of goods up and down. The lifting height of the lifting cargo elevator varies from meter to meters,HejianMobile hydraulic boarding bridge, and special specifications of lifting and lowering cargo elevators can be customized according to user requirements According to the type, it can be divided into:; Scissor fork type cargo elevator and guide rail type cargo elevator. Guide rail type elevator is a non scissor fork type cargo elevator mainly used for the transportation of goods between floors of workshops, hotels steel structure workshops, rooms, and warehouses without pits or machine rooms. Scissor fork type cargo elevators need to be prepared with pits before installation, and the elevator should be fixed and connected in the pit before being connected to the power supply The lifting cargo elevator utilizes hydraulic power units to generate pressure during operation, which drives the hydraulic oil cylinder as the main power to raise and lower the lifting cargo elevator platform.
