zabul Platform boarding bridgeTalking about the control technology process

Reasons for the hydraulic boarding bridge lifting platform not lifting: low voltage, motor reverse,zabul Mobile boarding axle hydraulic pressure, 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 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.

Slowly reverse and park the container under the lip at the front of the boarding bridge.

zabul .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.

During the application process of hydraulic boarding bridges, it is necessary to follow the operating procedures to ensure the normal operation of the equipment. What precautions should we take when using hydraulic boarding bridges?

.　　1. Before use, check the boarding bridge for obvious damage such as cracks and broken wires.

For slopes that are unstable or unstable after earthwork excavation, 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.

Open the manual valve slowly lower the boarding bridge, and secure more than 90% of the lip plates at the bottom of the container.

When confirming that the lip is fixed to the container, pull out the hook to hook it into the container, tighten the chain to ensure that it does not loosen,zabul Folding boarding bridge, and press the brake blocks on both sides. 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.

B) When maintaining the hydraulic system, only clean plastic plugs can be used to seal the ends of the pipeline.

The user department of the hydraulic boarding bridge should scientifically analyze the equipment and reasonably determine the investment in the equipment. At the same time, according to the characteristics of the work, ensuring timely loading and unloading of supplied materials; The normal operation of equipment needs to be guaranteed by institutional measures, improve relevant management systems, strengthen dynamic management of equipment faults, monitor the status of key parts, and analyze the patterns of faults through maintenance; It is necessary to ensure the supply of maintenance accessories, establish a spare parts warehouse for vulnerable and commonly used parts, and purchase channels to avoid situations where inadequate preparation may lead to extended downtime and increased repair costs; Users should maintain a close relationship with survival manufacturers strengthen the professional quality and professionalism of lifting platform maintenance personnel, it should be checked in advance before use so that they can handle faults in a short period of time.

Recommendation and consultation.To ensure that the hydraulic boarding bridge is in good condition, 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.

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.

Connection for. Enable forklift trucks to safely and quickly enter and exit transportation vehicles for loading and unloading operations.

　　1. Before use, check the boarding bridge for obvious damage such as cracks and broken wires.

Product range.Common&quo; Work” Steel structure planning can withstand uniform pressure, reduce skeleton torque, and be more robust than other channel structures.

Applicable scenarios: municipal road engineering inspection, street lamp maintenance, branch construction, signboard maintenance, intermediate shafts and bearings, cylinder pins and bearings, boom hinge shafts 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,zabul Manufacturing of boarding bridges, 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.

Tighten the manual valve to close it.

There are three movable boards on both sides of the air conditioning board, which can effectively prevent the adjustment board from falling down and keep the pressure foot in a safe state.
