XinminEmbeddedReasons 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,XinminBoarding axle manufacturer, 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.
During use, close attention should be paid to the condition of the equipment, and if there are any problems, the use should be stopped immediately.
Xinmin.Features: Shear mechanical structure, working height generally ranging from 6 meters to 14 meters, high stability after lifting the platform, wide working platform vehicle and high load capacity wide range of high-altitude work, suitable for multiple people working simultaneously. The power form can be selected according to different requirements (such as three-phase AC power supply, DC power supply, and internal combustion power supply). The manual hydraulic device can lift and retract normally in places with power outage or no power supply increase the telescopic platform car, and extend to necessary positions in case of insufficient length of the platform car, improving work efficiency.
After the boarding bridge work is completed, all parts should be scrubbed and cleaned. When not working, the workbench should be lowered to a low position.
.Connection for. Enable forklift trucks to safely and quickly enter and exit transportation vehicles for loading and unloading operations.
Common&quo; Work” Steel structure planning can withstand uniform pressure, reduce skeleton torque, and be more robust than other channel structures.
conduct.
Slowly reverse and park the container under the lip at the front of the boarding bridge.
Drain all the hydraulic oil in the oil tank, open the oil tank, take out the oil suction filter, clean it, and return it to the oil tank. Install it in its original position. Fill the fuel tank with new oil.
As an important part of the boarding bridge, the height can be adjusted according to the different vehicles of the goods, so that it can be level with the platform of the carriage for batch loading and unloading of goods. Due to the production of electric hydraulic boarding bridges by different manufacturers, the height of the design and manufacturing platform and the distance from the ground also vary, with heights ranging from 1000mm to 1200mm. The hydraulic lifting stroke height ranges from 300mm to 600mm, and the height of the electric hydraulic boarding bridge itself plus the stroke height is 1800mm, which can be met by almost all freight vehicles (with a general vehicle height of 1600).
Lets see.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,XinminTrain boarding bridge, warehouses, etc
When it comes to fixed hydraulic boarding bridges, I believe
The width of the boarding bridge also requires a certain width of its own. However, 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, 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 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.
wholesaler.The electronic operation is very simple. With just one button, the air conditioning panel will automatically rise. Release the button, adjust the plate to reduce itself, and the hinge is used on the truck.
Features: Generally, domestic brands are the main products, with a lightweight boom design, lightweight flexibility, good stability, automatic detection of leg reverse force, stop getting on if any leg loosens. When the chassis power system malfunctions, ensure that the platform car can be lowered and the rotating mechanism can be manually rotated. The cylinder rod is protected by a protective sheath, and the arm head is equipped with a dustproof device.
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.
Xinmin.Open the manual valve, slowly lower the boarding bridge,XinminBoarding Bridge Price, and secure more than 90% of the lip plates at the bottom of the container.
When replacing hydraulic oil, sometimes poor hydraulic oil can also cause noise on the hydraulic boarding bridge, as well as noise when the pump station enters the air.
During the excavation process of the foundation pit of the simple boarding bridge, collision of the support structure should be prevented, and changes in the soil wall should be paid attention to at all times. If any abnormal phenomena such as cracks are found, construction must be suspended and reported to the superior for handling.
