Check and clean the driving gears and guide wheels of the elevator. If there is excessive wear, it is necessary to replace themRegarding 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, and the counterweight steel wire rope bracketGaobeidian,Folding arm lifting platform product features Folding arm lifting platform High altitude operation platform degree rotation without external power supply, can work across obstacles, lifting smoothly and safely. The curved arm lifting platform adopts a curved arm working arm, and the scope and space of operation are not affected.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,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, it is necessary to regularly inspect the lifting stage and tighten any loose components. 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, 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.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 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.Attention: 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.
Regularly check all wires and cables for damage. Timely bandage and replace damaged parts.Jinchuang lifting platform product feature is mainly used for high-altitude cargo transportation between floors. With a load capacity of - tons and a lifting height of - meters, a guide rail elevator, also known as a hydraulic elevator, can be installed indoors and outdoors. The lifting height is high and uses a side mounted oil cylinder, which runs smoothly, has low noise, is convenient for maintenance, and has a long service life. In case of power outage manual emergency descent can be used, which is safe, convenient, fast, and practical. The pit depth is generally cm-cm, and the top layer height is not affected, The pump station can be customized according to the on-site environment, suitable for - floors of steel structures or concrete factories. Both the internal and external parts can be used. The pump station adopts a joint venture pump station and an imported pump station from Italy. If the speed requirement is too high, a joint venture customized pump station can be used to meet the ideal delivery requirements. The oil cylinder and seals are made of imported components, solving the problem of unstable oil pressure for customers, The oil leakage problem of components .

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 oilCheck the safety interlocking equipment of the first cut door of the hanging cage
Weekly maintenance: According to the operation instructions, ensure that the elevator is inspected and smooth every dayQuality Assurance, so how does the manufacturer calculate the price of elevators? In general, the manufacturer calculates the price of the elevator for customers based on the actual size, height, and carrying capacity of the on-site reserved opening provided by the customer Customers do not need to pay too much attention to the price difference between different elevator manufacturers when purchasing elevators, as the different materials used, material brands, and production processes result in different prices for elevators Customers can consider the cost-effectiveness of elevators more when purchasing, with the principle of getting what they pay for. Safety hazard elimination plan for lifting cargo elevators: When there is a malfunction or abnormal situation in the lifting cargo elevator, it can be put back into use The lifting platform adopts a fully hydraulic lifting mechanism, which can be operated inside the platform bucket and on the elevator body. The working arm of the lifting platform can rotate degrees. The hydraulic system is equipped with a safety explosion-proof valve to prevent the main boom oil cylinder oil pipe from bursting. The hydraulic legs are equipped with a hydraulic locking device to prevent the leg oil cylinder from retracting.
