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, overflow valve pressure is low, oil level is too low, oil pump is empty oil suction filter is blocked, 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 oil suction section is leaking, 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.

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,ShuangluanBoarding axle hydraulic mobile type, rain, and sunlight,ShuangluanMobile boarding axle hydraulic pressure, 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.

Shuangluan.(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.

Monthly maintenance of hydraulic boarding bridges: check for wear on rollers, 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, 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.

When the hydraulic oil is insufficient, the hydraulic pump will produce suction phenomenon, 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.

What should I pay attention to when choosing a boarding bridge? The selection and purchase of the boarding bridge involves paying attention to three issues, including its range of use, rated load, and other factors; Their understanding of the manufacturer of the boarding bridge, whether their enterprise qualifications, special equipment licenses are complete, how many after-sales service outlets are there in the country, and whether they are timely; The important point is whether the quality is good or not, you can choose the products of the manufacturer.

During construction, the factors of loading and unloading operations were not taken into account. The platform type loading and unloading bridge serves as a remedial solution and can also meet the requirements for loading and unloading operations into truck carriages. The platform type boarding bridge is also designed in various structural forms according to different on-site conditions. It can also be adjusted up (below the cargo platform) or down (below the cargo platform) within a certain range, which can meet the installation and use of most loading and unloading platforms. Is the boarding bridge easy to use? The boarding bridge is an auxiliary equipment used to bridge with the freight car and is designed to solve the height difference between the freight car and the ground. Suitable for fixed or mobile loading and unloading of goods, it is actually equivalent to a slope, allowing forklifts to smoothly enter the carriage to load and unload goods, requiring only one person to quickly load and unload goods, which is labor-saving.

The mobile boarding bridge is a type of forklift that directly loads and unloads goods from the ground to the truck

When replacing hydraulic oil,ShuangluanHydraulic boarding bridge, sometimes poor hydraulic oil can also cause noise on the hydraulic boarding bridge, as well as noise when the pump station enters the air.

Analysis project.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.

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.

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.

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?

Direct labor.The pressure on the axle will reduce the service life of the boarding axle.

Advantages: Widely used high-altitude work equipment, stable and safe, with a wide range of operations.

When it comes to fixed hydraulic boarding bridges, I believe

Shuangluan.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).

When it comes to fixed hydraulic boarding bridges, I believe

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, etc
