a layer of rust resistant primer is usually applied

Manganese steel is generally used as the primary profile for warehouse cargo elevators. In order to achieve better anti-corrosion effect, which effectively blocks air and prevents premature corrosion of the steel. Below, Ruilong hydraulic press will explain the role of rust resistant primer.Clean and inspect the crown wheel frame assembly, correct or replace with new partsHanover,HanoverHydraulic aluminum alloy lifting platform,According to GB/T-, when one of the following situations occurs in the curve related to the aging frequency, it can be determined that the area covered by the effective zone of the vibration mode at that frequency has reached the aging effect: the curve rises and flattens; The curve rises, then falls, and then flattens; The resonance frequency of the a-n curve after vibration is lower than that before vibration; The bandwidth of the a-n curve after vibration narrows compared to before vibration; The resonance peak of the a-n curve after vibration exhibits fission phenomenon; The curve flattens out after descent.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.Lo Prado,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,HanoverSelf propelled lifting platform, and the counterweight steel wire rope bracketMonthly maintenance: View weekly inspection itemsWith 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.

Check the relative orientation between the cable support wall and the cable guide frameEmergency stop: Press the emergency button switch to raise or lower the machine.Check the interlocking equipment, up and down travel, and other safety maintenance switches of the cage door and fence doorDesign brand, 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 dismantle the gearbox. Clean all components and seals, replace excessively worn and deformed parts and smooth oil

Clean and inspect the crown wheel frame assembly, correct or replace with new partsThe cost is reasonable,Weekly maintenance: According to the operation instructions, ensure that the elevator is inspected and smooth every dayThermal aging stress relief is generally suitable for small workpieces, while the lifting foundation structure has a large volume and does not have a large enough annealing furnace. Using natural aging takes one year and the production cycle is too long, so neither of these two methods is feasible. After research and understanding by the manufacturer, it was found that selecting appropriate support points for large welded structural components can perform vibration aging stress relief. Therefore, the manufacturer has decided to use vibration aging for stress relief of the platform lifting foundation. Long term promotion of downgrading manufacturers, old brands, price advantages, and guaranteed quality!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?Hanover,HanoverAluminum alloy double column lifting platform,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, power on the suspension cage to lift it m above the ground or detach it from the ground buffer spring (or support). The adjustment and sequence are as follows: . Use a special wrench to rotate the lower double (single) pendulum eccentric shaft to adjust the eccentricity to ensure that the installation plate surface of the driving mechanism is perpendicular to the horizontal plane, 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 easier it is to damage the gears and racks.Weekly maintenance: According to the operation instructions, ensure that the elevator is inspected and smooth every dayAdjust and correct various safety doors and mechanical interlocking equipment
