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 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.MILUS,Power supply voltage: Motor power: Lifting: Rocker self reset switch operation Overload protection: Over current relay.Check the fastening status of the wall bracket, support rod, and bolts and retaining rings between the lifting cargo elevator and the bridge. If they are loose or displaced, they should be checked and tightenedEwarton,With 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.Quarterly maintenance: Check the items checked each monthThe 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.

Check and repair the electrical circuit and control panel switch components. If there is aging in the circuit replace itNow with the arrival of summer, the aluminum alloy lifting platform will certainly suffer from high temperature and rainstorm in summer. It is easy to rust after a long time under this condition, which will seriously shorten the service life of the equipment and cause safety problems. So how should we prevent equipment rust?The frequency conversion system circuit of the construction elevator is mainly composed of two parts: the main circuit and the circuit.

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, 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.queryDrop 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 oilWhen 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,MILUSSelf-propelled lifting platform, and its meshing surface is not less than %. The meshing clearance should be suitable for each box,MILUSSingle mast aluminum alloy lifting platform, 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.On the contrary, loosen the connecting nut of the eccentric shaft of the guide roller and the tooth back pressure wheel as shown in , 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.

Check the wear condition of the pinion and rack,MILUSPrice of 10 ton mobile boarding bridge, please refer to the instruction manual for specific requirementsService first,Regularly 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)Power supply voltage: Motor power: Lifting: Rocker self reset switch operation Overload protection: Over current relay.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 bearingMILUS,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, as well as factors such as heat and deformation, coupled with rapid wear and tear, it is easy to cause the previously fastened components to loosen.Ensure that power cables and electrical circuits are not damagedCheck the oil level of the gearbox and make up for new oil if necessary
