da tong3-meterSelection of the location of the loading and unloading lifting platform In order to reduce the cost of material handling the location of the platform should be selected to minimize the distance of the handling tools and vehicles in the factory. It is much easier to move a fully loaded transport vehicle to a designated location outside the building than to transport the loaded materials one by one to the designated location indoors. When selecting a platform location, full consideration should be given to the production process and operational needs of the factory. There are two modes of platform layout: merging: loading and unloading on the same platform.
Pre install equipment, maintain unobstructed access roads and sufficient parking space before pre installation. Some hydraulic cargo elevators require heavy lifting assistance for installation some require equipment such as forklifts for installation,da tongfork lifter, and some can be pre installed manually. When it is necessary to install with the assistance of a truck crane and a forklift full consideration should be given to whether the on-site environment meets the working conditions of the truck crane.
da tong.The hook or rope of the seat belt should be hung on a sturdy and sturdy component or a steel wire rope specifically designed for hanging the seat belt. Prohibit hanging on moving or unstable objects.
When using hydraulic elevators,da tongHydraulic lifting platform cargo elevator, the main causes of noise are mechanical mechanism failures, hydraulic system failures, electrical equipment or component failures, etc. Today, the manufacturer of hydraulic cargo elevators will introduce to you the reasons for the noise generated by hydraulic elevators.
.Mobile is a type of cargo heavy machinery equipment with good adjustment reliability and wide application fields, suitable for automated production lines
When the hydraulic system malfunctions, the hydraulic elevator may experience problems with the hydraulic pump, motor, valve, which can easily cause vibration and generate significant noise.
The hydraulic lifting platform is a manually movable type, and the lifting power of the platform is a two machine or three-phase power supply. It has manual and electric power, and is also equipped with a hand pump for use in case of power outage. This series of platforms have the characteristics of flexible movement, stable lifting, and easy operation, and are mainly used in factories, government agencies, commercial stores, and the construction and decoration industry.
The installation personnel should have the qualification for installing hydraulic cargo elevators, carefully implement the special construction plan for installation and construction, and provide safety technical disclosure to the installation personnel for technical design.
Based on experience, new steel wire ropes will not suddenly break when used under normal circumstances, unless incorrect operation or safety protection devices fail, as the load borne by the steel wire may exceed its breaking capacity. The damage to the steel wire rope of the cargo elevator is mainly gradually formed during long-term use. After a certain period of repeated bending and friction, the steel wire on the surface of the steel wire rope will experience bending fatigue and wear, and the steel wire on the surface layer will gradually break. At this point, if it cannot be used again, it should be replaced in a timely manner to ensure the safety of the hydraulic platform.
The hydraulic lifting platform often checks the connection status of each part, and there are also some forms of elevators that are not common it should be tightened. The connection bolts of the machine body should be checked for tightness when the elevator body is under pressure (the compression condition can be formed by rotating the arm). All connecting shafts need to have split pins and need to be fully opened.
where.The above are the working principles of three common elevators, such as cylinder mounted elevators, curved arm elevators, car mounted elevators, etc. Their common feature is the hydraulic principle for operation, because the stability of the hydraulic system can bring better user experience and safer operation to the equipment, which has been favored by many users.
The development of elevators is at its peak, as many manufacturers have chosen more multi-story buildings to fully utilize the site, so they also need a device to facilitate the improvement of goods.
Reason: Manual pump and gear pump have severe oil leakage. Cleaning method: Replace the oil pump sealing ring to clean it. Reason: Gear pump is damaged, The oil pumped out has no pressure. Cleaning method: Replace the gear pump to clean the problem. Reason: Lack of hydraulic oil. Cleaning method: Add enough hydraulic oil to clean the problem. Reason: Circuit open. Cleaning method: Check the button and fuse to clean the problem. Reason: Filter blockage. Cleaning method: Replace or clean the problem. Reason: Support valve or electromagnetic directional valve malfunction. There are two situations: the input voltage of the electromagnetic coil is lack of 220V. The solenoid coil is burnt out and the valve core is stuck. Cleaning method: maintenance or replacement can be used to clean the natural descent of the lifting platform. Reason and cleaning method: one-way valve leakage cleaning method: check the check valve in the valve. Assuming there is dirt on the sealing surface of the check valve. Clean the check valve.
Hydraulic lifting table: the hydraulic lifting table is widely used in various industrial enterprises and production lines such as automobile, container, mold manufacturing wood processing, etc., to meet the lifting needs of different operation heights, and can be equipped with various table forms (such as ball, roller, steering, telescoping), and with various ways (separate, linkage, explosion-proof), it has stable and accurate lifting, frequent starting The characteristics of large load capacity effectively solve various lifting and lowering difficulties in industrial enterprises, making production operations smooth.
Work courses.There is noise inside the hydraulic cylinder. When replacing the hydraulic oil, there was air in the hydraulic cylinder due to an operational error. Under high pressure, it is easy to generate cavitation and high-frequency noise. When the rod is bent or replaced with a new seal, the new seal is too tight, which can also produce significant noise. If it is a problem of tight sealing, the noise can be reduced after running in for a period of time. If the rod is bent, it needs to be corrected. In addition, hydraulic pipelines should use hoses as much as possible, even when arranging pipelines, it can reduce vibration and noise, and the pipelines should avoid dead bends as much as possible.
Check valve leakage, oil pipe check valve leakage. The solution is to carefully check whether the one-way valve is functioning properly. If it is not normal, it is recommended to replace the one-way valve with a new one.
Voltage too low: Measure the starter voltage, with an allowable fluctuation range of± 10%.
da tong.When using an electric mobile scissor lifting platform outdoors, if the wind force exceeds level 5, please stop using it; When the lifting height exceeds 10 meters, the wind ropes at the four corners of the hydraulic lift platform should be tightened and fixed, and the support legs should be reinforced for protection and stability to avoid safety accidents caused by excessive swinging of the electric lifting platform
Protective device: In case of power or oil circuit failure, there should be a safety rope to prevent the workbench from falling out of control. (Allow controlled descent)
When installing, disassembling, and adjusting the rotating mechanism, attention should be paid to ensuring that the middle line is parallel to the middle line of the gear, and its meshing surface is not less than 70%. The meshing clearance should be suitable for the brakes of each mechanism. The clearance between the brake wheels should be regularly checked and adjusted to ensure its flexibility and reliability. There must be no dirt on the friction surface and it must be cleaned with gasoline or diluent.
