ShijiazhuangBuDuring the application process of hydraulic boarding bridges, it is necessary to follow the operating procedures to ensure the normal operation of the equipment. What precautions should we take when using hydraulic boarding bridges?
As an important part of the boarding bridge, the height can be adjusted according to the different vehicles of the goods, the height of the design and manufacturing platform and the distance from the ground also vary, with heights ranging from 1000mm to 1200mm. The hydraulic lifting stroke height ranges from 300mm to 600mm, and the height of the electric hydraulic boarding bridge itself plus the stroke height is 1800mm, which can be met by almost all freight vehicles (with a general vehicle height of 1600).
Shijiazhuang.The natural frequency of the air spring is stable, so its performance is also stable, which means that the air spring is closer to the ideal state. How does the air spring change the air pressure in the airbag with different loads to achieve the goal of keeping the distance between the car body and the road surface unchanged. The height valve 3 shown serves this purpose. The height valve is fixed on the frame and the connecting rod is connected to the hydraulic boarding bridge. The height valve has two valves, namely, the charging valve for air supply and the air release valve for air supply. These two valves are both connected by the rod. When the car load increases, the boarding bridge moves close to the frame, the connecting rod rises. When the connecting rod mechanism opens the charging valve, compressed air enters the air spring, and the frame and body rise until the height of the body is restored.
Embedded boarding bridge, as the name suggests, refers to the boarding bridge embedded in the loading and unloading operation platform. The installed boarding bridge main board surface is horizontal with the upper plane of the loading and unloading operation platform. Completely integrated into the platform, it will not affect other operational tasks on the platform without loading and unloading operations. The boarding bridge with this type of structure is widely used and is also a relatively fast boarding auxiliary device. Its design is usually fully standardized as early as the structural design of buildings. We are a long-term manufacturer of boarding bridges. Welcome to inquire
.Check if the manual valve is open. When using, it must be opened, otherwise the boarding bridge may be damaged.
During construction, the factors of loading and unloading operations were not taken into account. The platform type loading and unloading bridge serves as a remedial solution and can also meet the requirements for loading and unloading operations into truck carriages. The platform type boarding bridge is also designed in various structural forms according to different on-site conditions. It can also be adjusted up (below the cargo platform) or down (below the cargo platform) within a certain range, which can meet the installation and use of most loading and unloading platforms. Is the boarding bridge easy to use? The boarding bridge is an auxiliary equipment used to bridge with the freight car and is designed to solve the height difference between the freight car and the ground. Suitable for fixed or mobile loading and unloading of goods, it is actually equivalent to a slope, allowing forklifts to smoothly enter the carriage to load and unload goods, requiring only one person to quickly load and unload goods, which is labor-saving.
What are the issues to pay attention to when using the boarding bridge? For example, mobile boarding bridges are generally used outdoors, and after use they are also placed outdoors. They are often exposed to wind, rain and sunlight, which reduces the lifespan of the boarding bridge. Therefore, the maintenance of the boarding bridge is very important. When it rains, cover the boarding bridge with a rain cloth to prevent rusting and aging.
Common&quo; Streamline” Open joint planning, with a welding area more than three times that of other traditional pipeline joints, greatly extending the service life and protection life.
Applicable scenario: Suitable for mobile high-altitude operations such as setting and inspection of high-altitude equipment in various industries.
As we all know
Test conclusion.To ensure that the hydraulic boarding bridge is in good condition,ShijiazhuangHydraulic flow boarding bridge, press the up button, the motor rotates but the lifting table does not rise. This may be due to the reverse connection of the three-phase power supply and the motor reversing. Only the power supply needs to be corrected, so it is not a major problem.
Reason for the lifting table not lowering: The lowering valve is malfunctioning, and the lowering speed valve is out of adjustment. Solution: When pressing the lowering button, check if the lowering valve is energized. If there is no electricity,ShijiazhuangTelescopic boarding bridge, try to eliminate it; If there is electricity, check the boarding bridge for obvious damage such as cracks and broken wires.
To ensure that the hydraulic boarding bridge is in good condition, it should be checked in advance before use mainly including whether the buttons are effective; Whether the power cord and socket are intact; Whether the oil pipeline is intact; The stability of the guardrail; The tightness of bolts at each junction point; The appearance quality is intact. But when the power is turned on and the indicator light is on, press the up button, the motor rotates but the lifting table does not rise. This may be due to the reverse connection of the three-phase power supply and the motor reversing. Only the power supply needs to be corrected, so it is not a major problem.
Direct material.The safety valve of the mobile hydraulic boarding bridge can also generate high noise. When air is mixed into hydraulic oil, the relief valve gets stuck or severely worn, and the fatigue deformation of the relief valve spring leads to unstable pressure regulation of the relief valve. The pressure release time of the relief valve is too short, which can easily lead to local stability of the pilot valve performance of the relief valve. Noise is generated by the vibration of the pilot valve's air. Therefore, we should regularly clean the safety valve, and replace it if it is damaged or severely worn.
Remove and disassemble the lowering valve, blow the valve core clean with compressed air, and then reinstall it.
There are three movable boards on both sides of the air conditioning board, which can effectively prevent the adjustment board from falling down and keep the pressure foot in a safe state.
Shijiazhuang.For slopes that are unstable or unstable after earthwork excavation, top-down segmented trench jumping should be adopted based on the geological characteristics and possible situations of the slope, and reverse construction or partial reverse construction should be carried out in a timely manner. It is strictly prohibited to excavate and explode indiscriminately.
The width of the boarding bridge also requires a certain width of its own. However, if the width is too small, it is not conducive to forklift loading and unloading of goods. If the width is too large, it can occupy a certain space, which is not necessary. So a reasonable width is necessary, usually the width of the electric hydraulic boarding bridge is 1800mm, 2000mm, and 2100mm. The width of the bridge is divided into internal width and total width. As we have already mentioned, the internal width is the width of the passage, and the total width mainly refers to the width of the guardrails on both sides plus the width of the passage. The total width can be ignored in use,ShijiazhuangMechanical fixed boarding bridge, but everyone still cares about the internal width which is the width of the channel.
The user department of the hydraulic boarding bridge should scientifically analyze the equipment and reasonably determine the investment in the equipment. At the same time, according to the characteristics of the work, ensuring timely loading and unloading of supplied materials; The normal operation of equipment needs to be guaranteed by institutional measures, improve relevant management systems, strengthen dynamic management of equipment faults, monitor the status of key parts, and analyze the patterns of faults through maintenance; It is necessary to ensure the supply of maintenance accessories, establish a spare parts warehouse for vulnerable and commonly used parts, and purchase channels to avoid situations where inadequate preparation may lead to extended downtime and increased repair costs; Users should maintain a close relationship with survival manufacturers, strengthen the professional quality and professionalism of lifting platform maintenance personnel, so that they can handle faults in a short period of time.
