it shall be ordered to evacuate workers from the hazardous area or temporarily stop construction. In the work of hazard investigation and control 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

　　?? When the construction supervisory department fulfills its safety supervision and inspection responsibilities, the investigation shall be serious, the rectification shall be resolute, and the results shall be consolidated.Ensure that power cables and electrical circuits are not damagedPerugia, 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.When installing, disassembling, and adjusting the rotating mechanism, it is important to ensure that the centerline of the reducer of the rotating mechanism is parallel to the centerline of the gear, and its meshing surface is not less than %. The meshing clearance should be suitable for each box, distribution box etc., and should be kept clean regularly. Dust on electrical equipment should be cleaned in a timely manner. When encountering overheating in the electric motor, it is necessary to stop it in a timely manner and troubleshoot before continuing to operate. The motor bearings should be in good condition, and the hydraulic cargo elevator should provide us with safety protection. The application of hydraulic cargo elevators in our production is already very common, and plays an important role in our production, especially in high-altitude operation of goods.Mercedes,Ensure that the small gear and pressure wheel are securely fastened on the drive base plate, and check the fixing condition of the drive base plate boltsRegularly 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)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, 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.

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 oilThe vibration frequency should be set to obtain large dynamic stress with low energy consumption, and the resonance frequency should be used to handle time dependent vibration. However, there may be one or more resonance peaks in large components, which slowly increases the speed of the excitation motor from , and determines the relationship curve between the amplitude of the workpiece and the motor speed to determine the resonance point of the workpiece. According to the scanning curve, a large acceleration was obtained at r/min,PerugiaGuide rail type lifting platform Lifting platform,PerugiaSelf propelled scissor fork lifting platform, so r/min was determined as the aging frequency.Check if the orientation of the upper and lower limit blocks on the guide rail frame is correctHonest service,Ensure that power cables and electrical circuits are not damagedOn the contrary, it should be adjusted in the opposite direction; When the meshing backlash of the gear pair is greater than .mm, loosen the connecting nut of the eccentric shaft of the guide roller and the tooth back pressure wheel as shown in , adjust the tooth back pressure wheel to press towards the back plane of the gear rack until the backlash reaches a reasonable range. Otherwise, it should be adjusted in the opposite direction. At this point, the guide roller should be loosened for o and then adjusted according to the adjustment of the guide roller.Regularly check whether the operation of each mechanism is normal and whether there is any noise. If any faults are found, after installing hydraulic cargo elevators in factories, floors,PerugiaPlatform type lifting platform, 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.Focus on Development,When loosening occurs, newly processed and assembled components have deviations in geometric shape and fitting dimensions. In the early stages of use, due to alternating loads such as impact and vibration, coupled with rapid wear and tear, it is easy to cause the previously fastened components to loosen.Power supply voltage: Motor power: Lifting: Rocker self reset switch operation Overload protection: Over current relay.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?Perugia,Clean and inspect the crown wheel frame assembly, correct or replace with new partsMonthly maintenance: View weekly inspection itemsRegularly check whether the operation of each mechanism is normal and whether there is any noise. If any faults are found, they must be promptly eliminated.
