and carefully inspect the steel structure

　　?? 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, safety protection devices, electrical devices, and transmission devices of construction elevatorsLeakage 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, 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,TongliaoMobile scissor fork lifting platform, leading to the occurrence of faults.Tongliao,Outbound call form: Outbound call boxes are pre embedded or installed in a column style on the wall or ground near the parking floor above and below the platform, and are linked to operate the platform up and down.Check the protective cable condition of the cable guide frameLeogane,Regarding the construction elevator with counterweight, check the adjustment and fixation status of the counterweight guide wheel. Check the balancing equipment of the steel wire rope, the crown wheel, and the counterweight steel wire rope bracketThe 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, the ground turntable and the high-altitude work bar. However, 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.Adjust and correct various safety doors and mechanical interlocking equipment

Organize, 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 membersThe driver shall close and lock the movable doors at both ends of the protective fence before work, and then ring the bell to start. It is strictly prohibited to work with the movable doors of the protective fence open. In case of special circumstances during platform operation, the emergency stop switch can be used to stop the platform. However, during normal operation, it is prohibited to use the emergency stop switch to stop the platform.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?Welcome calls ,　　?? The supervision unit shall effectively fulfill its safety responsibilities,TongliaoLarge fixed lifting platform, 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, racks they shall promptly report to the construction unitPlease refer to the instruction manual for the maintenance and maintenance of the elevator to check the braking torque of the brakeAttention: 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, rollers, and guide rails. If adjusted more carefully, it will be more beneficial for the service life of the elevator.

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 cleanExcellent service,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, 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.Emergency stop: Press the emergency button switch to raise or lower the machine.The reduction gearbox, gearbox, external meshing gear and other parts, as well as the hydraulic oil, are all carried out according to the requirements in the table.Tongliao,Check and repair the electrical circuit and control panel switch components. If there is aging in the circuit, replace itMonthly maintenance: View weekly inspection items　　?? The supervision unit shall effectively fulfill its safety responsibilities, they shall promptly report to the construction unit

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
