If there is a problem with the gears or bearings of the hydraulic pump, which causes periodic changes in the hydraulic system pressure, it will also cause resonance in the hydraulic system and generate noise.
The manufacturer of hydraulic cargo elevators reminds the use of guide rail hydraulic lifting cargo elevators. Guide rail hydraulic lifting cargo elevators: Do not stand within the specified range, draw on the guide rail lifting platform, prohibit any idle personnel from entering the work area ensure that the work area is free of clothing, and maintain a clean and tidy workplace.
Huanghua.When working simultaneously at the upper and lower levels, a tight and firm protective partition, canopy or other isolation facilities must be erected in the middle of the boarding bridge, and workers must wear safety helmets.
Hydraulic lift cargo elevators belong to high-altitude work equipment. Small shaking of the scissor type structure is normal, but excessive deviation is a symptom. It is necessary to find the cause and make correct judgments in a timely manner. Generally speaking, operations above 8 meters are generally allowed. Due to its own weight, devices above this height begin to vibrate in different ranges. The vibration range depends on factors such as weight, lifting height, and intensity of high-altitude operations.
.The cylinder head oil seal is too tight or the rod is bent, which can also cause noise during movement due to other forces. At this point, the oil seal or straightening rod must be replaced in a timely manner.
When disassembling and adjusting the reverse organization of the equipment, attention should be paid to ensuring that the centerline of the reverse organization reducer is parallel to the centerline of the gear and its meshing surface is not less than 70%. The meshing gap should be appropriate.
Considering the oil level in the oil tank, when all hydraulic cylinders in the system are extended, and when the oil cylinders retract, the oil level should not be higher than the Z-high oil level. In fact, 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.
Road noise can also occur if tires are crushed against objects that are prone to noise. The shaking amplitude of the scissor type lifting platform is proportional to its lifting height. The higher the height, the greater the shaking. When using it at a working height of 10 meters, if possible,HuanghuaMast type aluminum alloy hydraulic lifting platform, please use safety protection measures
A lifting platform is a lifting device that lifts people or goods to a certain height. When vertical conveying is carried out in logistics systems such as factories and automatic warehouses, various flat conveying equipment is often installed on the lifting platform as a connecting device for conveying lines at different heights. Usually driven by hydraulic pressure, it is called a hydraulic lifting platform. In addition to being used for transporting goods at different heights, it is widely used for high-altitude installation, and other operations.

Due to its own weight, devices above this height begin to vibrate in different ranges. The vibration range depends on factors such as weight, and intensity of high-altitude operations.
Market trend.Pay attention to checking each steel wire rope for signs of broken wires and loose drums. If it exceeds the relevant rules, it is necessary to replace it immediately. The protection of steel wire ropes should strictly follow the rules of GB5144-85.
To consider its capacity, generally mobile equipment takes 2-3 times the high flow rate of pump Z, and fixed equipment takes 3-4 times.
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, 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.
When the hydraulic oil is insufficient, the hydraulic pump will experience suction, causing air to enter the hydraulic oil and producing high noise.
The cheapest.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.
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.
Users should arrange dedicated personnel to operate hydraulic elevators, formulate usage details and safety precautions for hydraulic elevators based on their own situation, and hang them on the
Huanghua.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, 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.
The combined platform is often used in small workshops with small volume of goods. However, because this platform needs to complete two functions at the same time, it inevitably increases the distance of handling tools/vehicles in the workshop.
The speed circuit is the circuit that switches the motion speed and speed of the actuator in the hydraulic system of the guide rail hydraulic lifting platform. Mainly including valves, pumps, and actuators. The commonly used speed circuits include speed circuits, high-speed circuits, and speed switching circuits.
