2023-12-27 00:33:27Reasons for the hydraulic boarding bridge lifting platform not lifting: low voltage, motor not rotating motor reverse, 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 % 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.Function: Convenient unloading, strong stability, and low maintenance cost. Suitable for various vehicles on loading and unloading sites and places with relatively busy traffic. Loading and unloading platform vehicles, lifting platform vehicles, which can effectively achieve anti slip function and is reliable.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.device management,When the hydraulic oil is insufficient, the hydraulic pump will produce suction phenomenon,JiningContainer loading and unloading bridge, causing air to enter the hydraulic oil and also producing high noise. 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.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.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 % 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.
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.where,Is the boarding bridge easy to use? Those who have used the boarding bridge know that it is a very useful mechanical equipment, which brings great convenience to the logistics industry and some industrial factories that need to load and unload goods. Some enterprises also value the development prospects of the boarding bridge and set up factory boarding bridges. High priced and various specifications of boarding bridge manufacturers provide timely supply with high cost-effectiveness, and has become the preferred brand for many wire products. Welcome to choose!Regularly draining and refilling the oil tank to remove water and sediment is crucial for removing impurities in the oil, but regularly emptying the entire hydraulic system is also crucial. This is a reliable way to completely remove system impurities, and other harmful substances. Then, the recommended clean hydraulic oil should be added back to the system. If the oil is completely contaminated, especially when the pump is damaged, the oil in the tank must be cleaned. The oil cleaning device allows the oil to flow until the oil pollution indicator shows that the oil is in a satisfactory state.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.Jining,Open the manual valve, slowly lower the boarding bridge, and secure more than % of the lip plates at the bottom of the container.The safety valve of the mobile hydraulic boarding bridge can also generate high noise. When air is mixed into hydraulic oil, 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 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.Install drainage ditches on the ground near the pit of the simple boarding bridge and take corresponding drainage measures for the top, surface, and foot of the slope, especially for the simple boarding bridge.
