BrasiliaMobile1. Before use, check the boarding bridge for obvious damage such as cracks and broken wires.
When working on the hydraulic boarding bridge, the support legs must be extended, and the support leg bolts must be adjusted to ensure that the lifting platform is stably stressed on the support legs and kept horizontal; During the lifting process and in the lifting state, the lifting platform must not be moved, and it is strictly prohibited to shake on the lifting platform. If there is an abnormal sound during the operation of the hydraulic boarding bridge, it should be stopped immediately for inspection to avoid causing serious damage to the lifting platform; Before use, check whether the electrical equipment is normal; All shaft pin oil holes must be oiled before each use. Before use, it is necessary to perform no-load lifting and check whether the hydraulic system is normal; The load of the workbench should not exceed the rated value, and it should not be subjected to intense manual shaking; The hydraulic oil in the oil tank must be replaced every 500 hours of operation.
Brasilia.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, and are more cost-effective. This is why mobile boarding bridges are now equipped with solid rubber tires.

Operation degree: There are two types of operations that can be used to raise and lower the boarding bridge. One is a manual pump station, which uses manual hydraulic lifting, which is labor-intensive and somewhat labor-intensive. Advantages: It can be operated and used in any situation. Two types of electric pump stations use electric hydraulic lifting and lowering, which reduces labor intensity and saves labor. Disadvantage: Once the power is cut off, it will not be able to be used, but now there are both manual and electric boarding bridges that are more convenient to use.
The hydraulic boarding bridge not only reduces labor intensity, but also doubles the efficiency of loading and unloading operations, accelerates logistics speed, and achieves significant economic benefits. Hydraulic loading and unloading bridge is a specialized auxiliary equipment for fast loading and unloading of goods. Its height adjustment function allows a bridge to be built between the truck and the cargo platform in the warehouse. Forklifts and other transport vehicles can directly enter the truck for batch loading and unloading of goods, also known as loading and unloading platforms.

(4) For the connection parts of the mobile boarding bridge, careful inspection should be carried out to check for any looseness, such as connecting bolts. If there are any, they should be tightened in a timely manner. In addition, for all connecting shafts there should be split pins that are thick and sufficient.
Install a 5m high protective railing around the foundation pit of the simple boarding bridge, with a distance of no less than 1m from the protective railing to the foundation pit. The mobile boarding bridge only requires a single person to operate, without the need for power supply, and can achieve safe and fast loading and unloading of goods. Mobile boarding bridges are widely used in cargo platforms and mobile loading and unloading sites without loading and unloading equipment. They are auxiliary equipment for cargo loading and unloading that is used in conjunction with forklifts. The sequence of earthwork excavation must comply with design conditions and follow" Trenching support, support first and then excavation, layered excavation, no overbreak&rquote; The principle of.

There is a lot of noise generated when using a mobile hydraulic boarding bridge. So, where are these noises caused? In fact, pump stations, steel cylinders, and steel equipment are all sources of noise. Today we will analyze for you: 1. The boarding bridge is already a very visible structural form in modern logistics sites. It is the point and endpoint of the enterprise logistics chain, and a loading and unloading operation platform for enterprises to quickly and safely turnover products and goods. The height of the loading and unloading operation platform is fixed, but there is always a certain height difference or gap between the transportation vehicles and the loading and unloading platform due to the height of the carriage. Causing the forklift to be unable to enter and exit the transportation vehicle for direct loading and unloading of goods. Use the boarding bridge to provide reliable connections. Enable forklift trucks to safely and quickly enter and exit transportation vehicles for loading and unloading operations. After hearing the noise from the hydraulic boarding bridge, first check if there are any problems with the hydraulic pump station, motor, and fixing device, and if the noise is caused by its vibration.
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, 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.
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.
safety requirements .For slopes that are unstable or unstable after earthwork excavation,BrasiliaHydraulic fixed boarding axle, 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 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.
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, we should regularly clean the safety valve and replace it if it is damaged or severely worn.
Brasilia.Do you know some of the working characteristics of hydraulic lifting boarding bridges? Today, I will take you to understand!
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, but everyone still cares about the internal width, which is the width of the channel.
The pressure on the axle will reduce the service life of the boarding axle.
