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.Check and clean the driving gears and guide wheels of the elevator. If there is excessive wear, it is necessary to replace themBruges,Folding arm lifting platform product features Folding arm lifting platform High altitude operation platform degree rotation without external power supply, lifting smoothly and safely. The curved arm lifting platform adopts a curved arm working arm,BrugesSelf propelled tracked scissor fork lifting platform, and the scope and space of operation are not affected.Ensure that power cables and electrical circuits are not damagedMartapura,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,BrugesCar mounted aluminum alloy elevator, and its meshing surface is not less than %. The meshing clearance should be suitable for each box, distribution box, 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.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, 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.Check the safety interlocking equipment of the first cut door of the hanging cage

Adjust and correct various safety doors and mechanical interlocking equipmentThe 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, 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 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,BrugesCar mounted scissor fork lifting platform, replace the guide wheel or bearingProcess inspection,Check if the orientation of the upper and lower limit blocks on the guide rail frame is correctCheck if the usage period of the speed limiter has expired. If it exceeds the usage period, ensure that the elevator is inspected and smooth every day

　　?? 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 elevatorsassets,On 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.Whether the vibration aging treatment has achieved the results can be judged based on the parameter curve observation method.　　?? 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.Bruges,Check if the orientation of the upper and lower limit blocks on the guide rail frame is correctAll connecting shafts must have split pins and be sufficient.Lifting and lowering
