Larosh on the Yonghe RiverSelf propelled scissor fork lifting platform,

The surface of each part of the brush should be kept clean, and the brush pressure should be adjusted to ensure that its area is not less than %.Organize, and reinforce the severely corroded load-bearing membersLarosh on the Yonghe River,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 if the orientation of the upper and lower limit blocks on the guide rail frame is correctParalimni,Adjust and correct various safety doors and mechanical interlocking equipmentWhen 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 as well as factors such as heat and deformation, it is easy to cause the previously fastened components to loosen.Check the clearance of the ball bearing and the wear of the suspension wheel guide wheel. If the roller is worn coupled with rapid wear and tear, it is necessary to adjust or replace it. If the elevator bearing is worn, replace the guide wheel or bearing

　　?? 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,Larosh on the Yonghe RiverRail guide rail type lifting platform, electrical devices, and transmission devices of construction elevatorsEmergency stop: Press the emergency button switch to raise or lower the machine.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, replace the guide wheel or bearingWelcome calls ,The frequency conversion system circuit of the construction elevator is mainly composed of two parts: the main circuit and the circuit. The main circuit is mainly composed of a construction lifting cargo elevator (hereinafter referred to as the lifting cargo elevator) driven by a more complex rectifier. Before installation, all the eccentric roller shafts of the lifting cage and driving mechanism are loosened or adjusted to a large eccentricity. The lifting cage and driving mechanism are installed in the guide rail frame respectively, and the two are connected. Starting from adjusting the driving mechanism, and ensure that the upper and lower pendulum wheels evenly guide the rails at the same time. Use your hand to move each wheel body and check if it evenly presses the rails; . Use a special wrench to rotate the eccentric shaft of the gear rack back pressure wheel to adjust the side clearance during gear rack meshing. When adjusting, use a feeler gauge to measure the side clearance to .; Between .mm, each pressing wheel should evenly press on the back of the rack. Move each wheel body by hand to check if it evenly presses against the tooth back. Similarly, adjust the guide rollers on both sides of the guide rail. The adjustment key is to adjust the guide wheel on one side of the guide rail to lightly press it onto the guide rail. When moving the wheel body by hand, it should be possible to rotate but there should be obvious obstruction; The roller on the other side should maintain a clearance of .-. ram with the guide rail; . Adjust the lifting cage according to the above and sequence. If the driving mechanism and the lifting cage are integrated into the lifting cargo elevator, the lifting cage should be adjusted according to the and sequence of adjusting the driving mechanism. Conduct a visual inspection of the operation of each roller, and use the lead pressing method and coloring method to check the meshing of the gear pair; Fine tune pairs of unsatisfactory parts. The key point is to carefully adjust the meshing status of the gear pair: when the spots shown in appear on the surface of the gear rack, it indicates that the driving mechanism is tilted towards the side of the guide rail. At this time, the lower swing wheel (single or double wheel) should be adjusted to move the lower part of the driving mechanism towards the direction of the guide rail until the area of the spots reaches more than % of the surface of the gear rack. The smaller the area, the easier it is to damage the gears and racks.Check if the orientation of the upper and lower limit blocks on the guide rail frame is correctManganese steel is generally used as the primary profile for warehouse cargo elevators. In order to achieve better anti-corrosion effect, a layer of rust resistant primer is usually applied, which effectively blocks air and prevents premature corrosion of the steel. Below, Ruilong hydraulic press will explain the role of rust resistant primer.

Check if the orientation of the upper and lower limit blocks on the guide rail frame is correctWhere can I find it?,Check the wear condition of the pinion and rack, please refer to the instruction manual for specific requirementsThe safety control voltage of is selected with rolling guide shoes, high accuracy, and stable lifting. The characteristics of the Jinchuang lifting platform are as follows: . There is no need for a machine room above the shaft. . The hydraulic elevator is not equipped with a counterweight device to improve the utilization rate of the shaft area. . The load and load cylinder of the hydraulic elevator directly act on the foundation pit, and the strength requirements of the shaft are low, Brick or brick concrete structure hoistway can be used for Jinchuang lifting platform safety and stability advantages. Overflow valve: It can prevent system pressure from being too high during upward movement. Emergency manual valve: In case of power failure, it can make the elevator emergency descend to the nearest floor position and open the door.Check the smooth steel wire rope and various fasteners,Larosh on the Yonghe RiverFour pillar aluminum alloy lifting platform, if there is excessive wear, it is necessary to replace themLarosh on the Yonghe River,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 cleaning oil for the hydraulic system must use hydraulic oil of the same brand as the system used, with an oil temperature between and ℃. Use a large flow rate to remove impurities from the system as much as possible. The hydraulic system needs to be cleaned repeatedly three times or more. After each cleaning, fully drain the system while the oil is hot.
