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, 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.Monthly maintenance: View weekly inspection itemsHorn,According to calculations, when the support points of the beam type components are located along the length of /L on both sides, the vibration resistance is relatively small, making it easy to obtain resonance and vibration effects with larger amplitudes. The geometric shape of the structure on the lifting foundation is similar to a long beam type component, two support points should be taken on each side for time treatment.Check the wear condition of the pinion and rack, please refer to the instruction manual for specific requirementsSan Pedro,　　?? When the construction supervisory department fulfills its safety supervision and inspection responsibilities, 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 the results shall be consolidated.Transfer of goods between floors of rooms, restaurants, and restaurants. The low height is between -mm, especially suitable for workplaces that cannot excavate pits. And there is no need for upper lifting points, double column, four column), stable equipment operation, simple and reliable operation, economic and convenient goods transmission,HornCurved arm lifting platform, and difficult to solve narrow spaces that cannot reach the requirements. A customized delivery platform can be created, and the product hydraulic system is equipped with anti fall, upper and lower door interaction and operation buttons can be set on each floor and lifting platform workbench to achieve multi-point. The product has a sturdy structure, a large load-bearing capacity, smooth lifting, simple and convenient installation and maintenance, making it an ideal and economical cargo conveying equipment for replacing elevators between low floors. The lifting stage device is mainly responsible for data processing of the operation mechanism and work bar of the vehicle, calculating the safety area of the lifting stage and is suitable for the electric control system of the self lifting stage lifting platform. The main sensors in the electric control system include angle sensors, long angle sensors, dual axis inclination sensors, and energy saving of the oil cylinder system.Ensure that the small gear and pressure wheel are securely fastened on the drive base plate, and check the fixing condition of the drive base plate bolts

All connecting shafts must have split pins and be sufficient. 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. The hydraulic system is equipped with a platform overload automatic protection device, In order to ensure the safety of operators, each section of the working arm on platform is equipped with safety limit devices. The hydraulic system seals on platform are all well-known domestic and foreign brands, and the power of the entire vehicle is a diesel engine with its own power supply. The power supply can also be used. The hydraulic lifting platform is equipped with an emergency lowering device in case of power outage. The folding arm lifting platform product can also use a Hz, V power motor,HornGuide rail vertical lifting platform, and diesel engine dual power.The 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.resources,Check if the orientation of the upper and lower limit blocks on the guide rail frame is correctRegularly check all wires and cables for damage. Timely bandage and replace damaged parts.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 bracket

Use a feeler gauge to check the wear condition of the worm gear of the worm gear reducer. Please refer to the instruction manual for specific requirementssuperior quality,Check if the orientation of the upper and lower limit blocks on the guide rail frame is correctHeavy load capacity: protective plate form: ° Or ° Interchangeable configuration rocker working angle: ° Drive method: hydraulic power unit drive or screw drive.What are the functions of anti rust primer for warehouse cargo elevators?Horn,When installing,HornDouble column aluminum alloy lifting platform, 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, and its meshing surface is not less than %. The meshing clearance should be suitable for each box, 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.Check if the usage period of the speed limiter has expired.
