The reason for the natural descent of the hydraulic boarding bridge lifting platform is that the one-way valve is leaking, the lowering valve is not tightly sealed, and the oil cylinder is leaking. Solution: Check the one-way valve in the valve group. If dirt is found on the sealing surface of a single valve, troubleshoot the lowering valve itself or replace the lowering valve. The slide valve of the lowering valve must be kept clean and move flexibly.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.Chengde,Staying below high-altitude work sites is prohibited, and safety nets or other protective devices should be installed below the work site to avoid injury from falling objects.For slopes that are unstable or unstable after earthwork excavation,ChengdeFolding boarding bridge, and reverse construction or partial reverse construction should be carried out in a timely manner. It is strictly prohibited to excavate and explode indiscriminately.Chalcis,Connection for. Enable forklift trucks to safely and quickly enter and exit transportation vehicles for loading and unloading operations.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,ChengdeRetractable 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!When working in foundation pits or depths, a helmet must be worn.

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 hours of operation.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.The correct operation of the hydraulic boarding bridge is good maintenance, and how to operate it correctly. Let me briefly introduce the operating steps of the hydraulic boarding bridge,ChengdeMobile lifting boarding bridge, hoping to bring more help to everyone.Quality inspection report,Connection for. Enable forklift trucks to safely and quickly enter and exit transportation vehicles for loading and unloading operations.The hydraulic boarding bridge is a specialized auxiliary equipment for achieving rapid loading and unloading of goods, malfunctions during use are inevitable. What should we do when encountering a malfunction?When the hydraulic oil is insufficient, the hydraulic pump will produce suction phenomenon, 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.

As we all knowApplication process,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, etcRegularly 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, oxidized hydraulic oil, and other harmful substances. Then the recommended clean hydraulic oil should be added back to the system. If the oil is completely contaminated, 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.Reasons for the hydraulic boarding bridge lifting platform not lifting: low voltage especially when the pump is damaged, 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.Chengde,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.When working in foundation pits or depths, a helmet must be worn.conduct.
