ZanstadIndoor After long-term use of the automatic lifting platform equipment, it is necessary to promptly solve the difficulties in starting the motor and abnormal sounds. Generally due to overload, insufficient power supply, and a small cross-sectional area of the power supply cable, the starting voltage drop is too large and the price of the cargo elevator is reduced.
Selection 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.
Zanstad.Many operating factories often require the use of hydraulic cargo elevators which can be lifted and lowered, making it very convenient to use. Many people do not know the knowledge of hydraulic cargo elevator lifting and adjustment. If they understand this knowledge, it will be helpful for future maintenance. The power unit of the fixed chain elevator for hydraulic lifting of cargo elevators drives the hydraulic oil to generate pressure, causing the oil cylinder to move back and forth to drive the lifting platform, thus achieving the adjustment of lifting speed. The power unit adjustment, whether it is a scissor type lifting platform or a track type lifting platform, is composed of the power unit and the oil cylinder. The power unit is manufactured with four outlet holes, which can be adjusted in size to increase or decrease the hydraulic oil flow rate of the oil cylinder, Adjustable motor speed or electro-hydraulic proportional valve to adjust hydraulic oil flow rate; The longer the oil pipe and hydraulic oil pipe, the longer the rise time. So during installation, try to minimize the length of the pipeline within the allowable range of the design; On the basis of adjusting the power device, the size of the oil pipeline can also be adjusted, and corresponding adjustments can be made while ensuring that the equipment meets normal demand and safety.
Optional configuration of fixed lifting platform: The fixed lifting platform can be equipped with auxiliary devices according to usage requirements, and can be combined in any combination, such as the safety protection device of the fixed lifting platform; Electrical methods; Form of work platform; Power form, it is necessary to check the fuse for repair and replacement.
After 1500 hours of elevator operation, perform minor repairs to the mechanical and electrical systems.
After 5000 hours of elevator operation, carry out medium maintenance on the mechanical and electrical systems.
Mobile is a type of cargo heavy machinery equipment with good adjustment reliability and wide application fields, suitable for automated production lines
Generally speaking, for situations with large lifting loads and small lifting heights, a lifting mechanism should be selected. For situations with small loads but large lifting heights, a lifting mechanism should be selected. According to the initial structure of the jacking, in order to meet the stability requirements, the size and lifting type of the oil cylinder are increased, and in order to achieve the same effective area as the jacking force, a lifting mechanism should be selected.
After long-term use of the automatic lifting platform equipment, it is inevitable that some malfunctions will occur. In order not to affect work, it is necessary to promptly solve the difficulties in starting the motor and abnormal sounds. Generally due to overload, insufficient power supply, and a small cross-sectional area of the power supply cable, the starting voltage drop is too large and the price of the cargo elevator is reduced.
Quality assurance.There is a phenomenon of self stopping when running up and down. Due to poor contact of the safety protection switch, it is easy for hydraulic cargo elevator manufacturers to cause this problem.
Regularly inspect the hydraulic lifting equipment of the upper and lower materials to ensure the safety of the rail type elevator and the safety of the material supply to the rail type lifting platform.
If the circuit of the device is not disconnected or lowered, it is necessary to check the fuse for repair and replacement.
Considering the oil level in the oil tank, when all hydraulic cylinders in the system are extended, the oil level in the oil tank should not be lower than the Z-low oil level, and when the oil cylinders retract, most manufacturers have noticed the above issues. The reason for the introduction is that most users can learn more about the equipment itself when using elevators in order to facilitate equipment maintenance. Hydraulic cargo elevator manufacturers sincerely hope that you choose a legitimate manufacturer when purchasing elevators, to avoid any worries about after-sales service.
Safety and health.When the hydraulic lifting platform is working, the load cannot exceed its rated load. When it is raised to a certain height, the larger the mass of the object, the greater the shaking
Clean the surface of the base and install anchor bolts. If the construction elevator is installed on the floor, use a pad iron under the base screws to increase the force surface between the nut and the floor, in order to reduce the impact of the nut on the floor; Insert steel plate gaskets of different thicknesses between the chassis and the foundation stone at the anchor bolts to adjust the verticality of the guide rail frame; Install three standard sections and measure the verticality of the guide rail frame using a theodolite; After adjusting the verticality of the guide rail frame, tighten the four foundation bolts; Adjust the verticality of the fence door frame as above and press it tightly
Lines of various safety equipment
Zanstad.The above are the working principles of three common elevators, and there are also some forms of elevators that are not common,ZanstadHydraulic fixed lifting platform, 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 guide rail type elevator has a structure of a straight top oil cylinder. The linear operation of the oil cylinder pulls the transmission chain, driving the lifting of the table to complete the operation. The guide rail type elevator is a popular form of cargo elevator in recent years,ZanstadHydraulic lifting platform, with the advantages of higher lifting height, stable operation, and simple maintenance compared to the scissor fork type elevator.
Hydraulic elevator manufacturers remind us that the basic principle of the hydraulic elevator speed control circuit is that the system often needs to adjust the movement speed of the hydraulic cylinder and hydraulic motor to adapt to the working cycle needs of the main machine. The speed of hydraulic cylinders and hydraulic motors depends on the displacement and input flow rate. It can be seen that changing the flow rate or displacement can affect the speed of the cylinder and motor.
