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, 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.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, 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.seaport,seaport8-ton mobile boarding bridge,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,seaportMobile scissor hydraulic lifting platform, so the excitation force is selected as the fourth gear.With the continuous development of the economy, meeting the needs of society, and increasing productivity, hydraulic cargo elevators play an important role in high-altitude operations. Hydraulic cargo elevators operate up and down, and can provide us with a safe and stable platform. We can provide security for our safety when working at heights.Karuzi,Ensure that power cables and electrical circuits are not damagedOrganize, 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 membersRegularly check the connection of each part and tighten it if there is any looseness. The tightness of the body connecting bolts should be checked when the body is under pressure (the rotating arm can be used to cause compression)

Check all standard sections and diagonal support connection points. Check the fastening bolts of the gear rack and ensure that the motor cooling wing plate and organization are cleanOutdoor guide rail lifting platform mainly used for high-altitude cargo transportation between floors. With a load capacity of - tons and an elevation of - meters, guide rail elevators, also known as hydraulic elevators, can be installed indoors and outdoors. They have a high lifting height and use side mounted oil cylinders, ensuring smooth operation, low noise, convenient maintenance, and long service life. In case of power failure, manual emergency descent can be used, which is safe, convenient, fast,seaportFixed guide rail lifting platform, and practical. The pit depth is generally cm-cm. Professional elevator manufacturers have high pressure resistance, good waterproof performance, and fire and high temperature resistance, Strong overload capacity, corrosion resistance, radiation resistance, long service life. The top layer height is not affected, and can be customized according to the on-site environment. It is suitable for - story steel structures or concrete factories, and can be used both internally and externally.　　Encyclopedic knowledge,Knowledge of pressure lifting platforms boarding bridges, mobile elevators and more is available in Jiuheng, Jinan. We sincerely welcome colleagues from all walks of life to visit and inspect the factory, cooperate and negotiate, and seek common development. The following maintenance and upkeep are required for the lifting cargo elevator: Maintenance and upkeep: Maintenance and upkeep should be carried out by the equipment operator or full-time personnel of the operating unit. The equipment maintenance and upkeep unit is responsible for supervising and reviewing the maintenance content. The main content of maintenance and upkeep is summarized as follows:; quot; Cross operation method; quot;: Clean, tighten, smooth, adjust, inspect all parts and components of the equipment to ensure they are normal. Apply oil smoothly according to rules pay attention to the sound of mechanical operation, and do a good job in cleaning and handover to achieve the goal of clean appearance and normal operation of the equipment. Maintenance and handover records should be made in a fixed form and used for managementLeakage 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.Adjust and correct various safety doors and mechanical interlocking equipment

Please refer to the instruction manual for the maintenance and maintenance of the elevator to check the braking torque of the brakeSampling inspection,Check and clean the driving gears and guide wheels of the elevator. If there is excessive wear, it is necessary to replace themDuring aging treatment, the equipment prints the vibration aging curve online. According to the curve, 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, zy drivers must carefully check the electrical, hydraulic, and mechanical systems of the platform, check the working range of the lifting platform truck, and new and old customers are welcome to come for consultationPlease refer to the instruction manual for the maintenance and maintenance of the elevator to check the braking torque of the brakeseaport,　　?? Hidden danger investigation relies on joint efforts from all aspects:?? Construction enterprises are the main responsibility for identifying hidden dangers in construction elevators.
