PreacherMobileI 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, the tightness of the connecting bolts of the body should be checked (the pressure state that can be used). All connecting shafts should have split pins and hydraulic cargo elevators should be fully opened.
Remember not to overload, overload is the root cause of many faults.
Preacher.High altitude work should always use tool bags. Tools with larger boarding bridges should be tied to sturdy components with ropes, and should not be placed randomly to prevent accidents caused by falling from a height.
Separate: Loading and unloading on different platforms.
.The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects). The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve, throttle valve, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure,PreacherFixed electric hydraulic lifting platform, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed. To ensure safe and reliable braking and prevent accidents, a hydraulic control one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure.
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, stable operation, and simple maintenance compared to the scissor fork type elevator.
Regularly check the operation of each mechanism for normal operation and noise. If any faults are found, the hydraulic cargo elevator wholesale should be promptly eliminated. Otherwise, it will affect the use of the guide rail hydraulic lifting platform. When refueling, the hydraulic oil should be filtered and filled, and the refueling tools should be reliable and clean. The hydraulic cargo elevator manufacturer should not remove the filter at the fuel tank filler to improve the refueling speed. Refueling personnel should use clean gloves and work clothes to prevent solid and fiber impurities from falling into the oil.
When the hydraulic oil is insufficient, the hydraulic pump will experience suction causing air to enter the hydraulic oil and producing high noise.
The manufacturer of hydraulic cargo elevators tells you the precautions for high-altitude operations.
If the circuit of the device is not disconnected or lowered, it is inevitable that some malfunctions will occur. In order not to affect work it is necessary to check the fuse for repair and replacement.
Development Curriculum.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.

The throttle valve regulates the flow rate and the ascending and descending speed. To ensure safe and reliable braking and prevent accidents, a hydraulic control one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline.

Emergency descent device: When a power driven chain elevator loses power, there should be a device to make the workbench emergency descend.
The main device does not engage. When this fault occurs, check whether the three-phase power supply is normal, whether the internal and external emergency stop button switches, the electric lock switch are turned on, whether the three-phase electrical phase sequence is correct, and whether the relay working indicator light is on.
Equipment maintenance.The hydraulic elevator overflow valve can also generate high noise. When air is mixed in hydraulic oil, the overflow valve is stuck or severely worn, the spring of the overflow valve is fatigued and deformed resulting in unstable pressure regulation of the overflow valve, it is easy to cause the pilot valve performance of the overflow valve to be partially stable and the relief time of the overflow valve is too short, causing air to vibrate inside the pilot valve and generate noise. So we need to regularly clean the overflow valve. When the overflow valve is damaged or severely worn, it should be replaced.
The above are common situations, and there are many other reasons based on the actual situation. Hydraulic lift cargo elevators can have different configurations according to the installation environment and usage requirements of the factory building.
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.
Preacher.Ensure that there is a suitable power supply at the installation site, and separate maintenance of the distribution box is required. The distribution box should have a leakage switch,PreacherHydraulic lifting platform, and the hydraulic cargo elevator construction site should be equipped with a fire extinguisher to prevent welding operations from causing fires. When selecting a leakage switch, it should be suitable for the operating power.
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
