I believe many people want to know about the maintenance issues of guide rail hydraulic lifting platforms, as it is related to their service life. During use, frequently check the connection of each part. If loose tighten it. When the body is under pressure, rust prevention is necessary. Because the part of the hydraulic cylinder needs to extend out of the cylinder during operation, it will naturally be corroded by oxides and acidic gases. This requires us to apply an appropriate amount of grease to protect it from erosion as a weight component. If we change the oil, we must open the box and use it for a long time to prevent the hydraulic cylinder from being used for a long time. In the operation of hydraulic cylinders, the speed should be appropriate and should not exceed 2m/s to extend the service life of the hydraulic cylinder. In addition, in order to protect the mechanism and safety, it is very important to install buffer devices internally to protect the hydraulic cylinder. The greater the pressure of the protective hydraulic cylinder, and the greater its pressure.

For hydraulic cylinders in hydraulic elevators, it is not practical to change their effective working area A (equivalent to displacement) to adjust the speed. Generally, the speed can only be adjusted by changing the flow rate. For variable displacement motors, speed regulation can change both the flow rate and the motor displacement.
.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 lifting platform is placed on a horizontal support surface, and the concentrated load of MAX load capacity is placed at any position 300mm away from the periphery of the workbench. After lifting 100 times, each load-bearing component must not have deformation or cracks.
Before installation, the installation personnel should confirm the infrastructure such as the foundation and shaft, pay attention to alignment, leveling, and alignment points, and confirm that the foundation meets the requirements before construction.
Hydraulic cargo elevators have been used in some high-altitude operations in recent years, and now some hydraulic cargo elevators are gradually mentioned as large machinery such as tower cranes, becoming a better choice for some high-altitude operations. However, there are still certain limitations, such as height and improving the quality of goods, which have certain constraints.
In on-site hydraulic elevators, it is difficult to detect the rising position, middle position, impact noise, and oil film leakage of hydraulic cylinders. Field observations have shown that the excessive lifting speed of the hydraulic cylinder has led to an increase in failure rate, seriously affecting production efficiency. The unstable hydraulic lifting requires an analysis of the hydraulic oil flow rate. Hydraulic pressing oil has poor quality and contains a large amount of impurities, which can also prevent slow and unstable lifting. In addition, there are other reasons: lifting the composition of the hydraulic ring. Oil pump, directional valve,PreacherGuide rail elevator, directional valve,PreacherHydraulic cylinder lifting platform, one-way throttle valve (without throttling), and lifting cylinder.
The elevator is evenly distributed at any position on the guide rail at 150% of the maximum load capacity, and should be stable at the maximum lifting height.

Generally, the speed can only be adjusted by changing the flow rate. For variable displacement motors, speed regulation can change both the flow rate and the motor displacement.
The manufacturer of the hydraulic cargo elevator tells you the reason and cleaning method: Reason: Overload cleaning method: Reduce the load to clean. Reason: The return valve is not closed. Cleaning method: Tighten the return valve to clean. Reason: The one-way valve of the manual pump is stuck and the return valve is malfunctioning. Cleaning method: Unscrew the bolt at the valve port of the oil pump, conduct maintenance cleaning, and replace the cleaning hydraulic oil to clean.
Emergency descent device: When a power driven chain elevator loses power, there should be a device to make the workbench emergency descend.
Reason: The lowering valve is not tightly closed. Cleaning method: Check if the lowering valve is powered on. If there is no power supply, clear the malfunction of the lowering valve itself or replace the lowering valve. It is necessary to keep the valve of the lowering valve clean and flexible.
Installation materials.This paper briefly introduces some matters that should be paid attention to in the selection of oil tank for hydraulic elevators. The main functions of the hydraulic oil tank for elevators in the hydraulic systems of hydraulic machinery such as elevators and hydraulic elevators are oil storage, heat dissipation, separation of air contained in oil and elimination of foam.
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, tighten the four foundation bolts; Adjust the verticality of the fence door frame as above and press it tightly
Load bearing capacity: The lifting platform is placed on a horizontal support surface, and the workbench is evenly loaded to 125% of the maximum load capacity. After lifting 100 times, each load-bearing component must not have deformation or cracks.
Preacher.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 the hydraulic oil is insufficient, the hydraulic pump will experience suction causing air to enter the hydraulic oil and producing high noise.
The optional configurations of a fixed lifting platform include manual hydraulic power, movable flip plates that are easy to overlap with surrounding facilities, rolling or motorized roller tracks, safety contact bars to prevent foot rolling, organ type safety protective covers, manual or motorized rotating workbenches, hydraulic overturning workbenches, safety support rods to prevent the lifting platform from falling, stainless steel safety nets, electric or hydraulic lifting platform walking power systems, and universal ball countertops.
