Tihei.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.
There is a flip plate at the top of the bridge deck, which is placed at the edge of the carriage to ensure a smooth transition between the passage and the carriage. Its advantages are as follows.
.During use, close attention should be paid to the condition of the equipment, and if there are any problems, and its height adjustment function can build a bridge between the truck and the warehouse platform. What are the operational steps we take during use?
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,TiheiVehicle mounted boarding bridge, 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, and replace it if it is damaged or severely worn.
Common&quo; Streamline” Open joint planning, with a welding area more than three times that of other traditional pipeline joints,TiheiMobile hydraulic loading and unloading boarding bridge, greatly extending the service life and protection life.
Solid rubber tires have no inflatable inner tubes and can move and work on various complex surfaces without worrying about puncturing the inner tubes, making them less prone to damage. They have stronger adaptability to the environment. Solid rubber tires have higher load-bearing capacity than ordinary pneumatic rubber tires of the same model, are more wear-resistant, have a longer service life, and are more cost-effective. This is why mobile boarding bridges are now equipped with solid rubber tires.
What are the issues to pay attention to when using the boarding bridge? For example mobile boarding bridges are generally used outdoors, 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.
analysis.It is strictly prohibited to apply excessive pile loads around the foundation pit.
Open planning before placement makes it easy to clean up clutter.
Monthly maintenance of hydraulic boarding bridges: check for wear on rollers, intermediate 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 40 to 50 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.
To ensure that the hydraulic boarding bridge is in good condition, it should be checked in advance before use,TiheiHydraulic boarding bridge, 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.
Online consultation.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, eliminate the malfunction of the lowering valve itself. The slide valve of the lowering valve must be kept clean and move flexibly. Readjust the overflow valve. Adjust at 100% rated load; Fill up the hydraulic oil; Clean the filter; Check the oil suction pipe and joints; Tighten the joint and replace it if necessary.
Usage environment: Able to adapt to specific working environments, such as working in highly corrosive, dusty, high-temperature, and low-temperature environments.
Open planning before placement makes it easy to clean up clutter.
Tihei.The platform side boarding bridge is directly installed at the front edge of the loading and unloading platform. There is no need to excavate or reserve pits on the loading and unloading operation platform, and there is basically no change to the building structure.
When working in foundation pits or depths, a helmet must be worn.
Connection for. Enable forklift trucks to safely and quickly enter and exit transportation vehicles for loading and unloading operations.
