MiddleburgRetractable boarding bridgeCleanliness inspection method

The slope of the electric hydraulic boarding bridge itself must have a certain slope to allow the forklift to enter the carriage for cargo loading and unloading. The length of the slope also varies from mm to mm,MiddleburgMaintenance of boarding bridge, mainly considering safety and stability of use. For a long time, the manufacturer of the boarding axle has no turnover to avoid the price difference, which is % higher than the market value! More than one ton is more expensive!Reasons for the hydraulic boarding bridge lifting platform not lifting: low voltage, motor not rotating, motor reverse motor phase loss (motor not moving and buzzing), indicator light on, press the up button, motor rotates but lifting platform does not rise, lowering valve is open, overflow valve pressure is low, oil level is too low, oil pump is empty, oil suction filter is blocked, oil suction section is leaking, and two phases in the three-phase line are arbitrarily changed; Solution: Check the starter potential during motor load operation. Voltage hydraulic range allowed± １０％； Check the motor and circuit; Check the circuit breaker and motor wiring; When the lowering button is released use a voltmeter to check whether the lowering valve is energized. If there is no power, check the circuit and eliminate the fault; If there is electricity,Applicable scenario: Suitable for mobile high-altitude operations such as setting and inspection of high-altitude equipment in various industries.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.Jessheim,Check if the manual valve is open. When using, it must be opened,MiddleburgFinished boarding bridge, otherwise the boarding bridge may be damaged.Do you know some of the working characteristics of hydraulic lifting boarding bridges? Today, I will take you to understand!Open the manual valve, slowly lower the boarding bridge, and secure more than % of the lip plates at the bottom of the container.

What should I pay attention to when choosing a boarding bridge? The selection and purchase of the boarding bridge involves paying attention to three issues, including its range of use, rated load, and other factors; Their understanding of the manufacturer of the boarding bridge, whether their enterprise qualifications, special equipment licenses are complete, how many after-sales service outlets are there in the country, how about their after-sales service attitude, and whether they are timely; The important point is whether the quality is good or not, and whether the price is reasonable. If both of these situations are reasonable, you can choose the products of the manufacturer.The above content mainly shares the importance analysis of regular maintenance of mobile boarding bridges with everyone hoping that everyone can take it seriously and not overlook it.Monthly maintenance of hydraulic boarding bridges: check for wear on rollers, boom hinge shafts and bearings cylinder pins and bearings, etc; The oil quality and level of hydraulic oil; The hydraulic boarding bridge should be raised throughout the entire process, and at this position, the hydraulic surface should be to millimeters higher than the bottom of the box. The hydraulic oil is darkened, sticky, or has foreign objects such as gravel. If found, it should be replaced in a timely manner; Add some oil to each part to extend the service life of the bearing. The hydraulic boarding bridge has a wide range of uses. Doing the above points well not only ensures your personal safety but also extends the service life of the equipment, making the boarding bridge better serve you.Industry management,These are the options for hydraulic oil for mobile boarding bridges.Portable hydraulic press boarding bridge: It is a widely used type, suitable for places where loading, unloading, and transportation are not fixed or moving; Mobile hydraulic press boarding bridge: suitable for fixed and immovable goods such as ports, cargo platforms, warehouses,The hydraulic boarding bridge is a specialized auxiliary equipment for achieving rapid loading and unloading of goods, and is our good helper. However, malfunctions during use are inevitable. What should we do when encountering a malfunction?The natural frequency of the air spring is stable, so its performance is also stable,MiddleburgManufacturing of boarding bridges, 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 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.As we all knowMiddleburg,The slope of the electric hydraulic boarding bridge itself must have a certain slope to allow the forklift to enter the carriage for cargo loading and unloading. The length of the slope also varies from mm to mm, mainly considering safety and stability of use. For a long time, which is % higher than the market value! More than one ton is more expensive!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, try to eliminate it; If there is electricity, troubleshoot the lowering valve itself or replace the lowering valve. The lowering valve should be kept clean.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.
