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?

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.

Karara.The emergence of mobile boarding bridges solves the problem of cargo loading and unloading auxiliary boarding equipment for forklifts entering the ground of freight containers and the height difference between trucks. The mobile boarding bridge can adjust the height of the mobile boarding bridge to be level with the height of the container according to the height of the truck container achieving rapid loading and unloading of goods and improving the efficiency of cargo loading and unloading. So, as the name suggests, refers to the boarding bridge embedded in the loading and unloading operation platform. The installed boarding bridge main board surface is horizontal with the upper plane of the loading and unloading operation platform. Completely integrated into the platform, it will not affect other operational tasks on the platform without loading and unloading operations. The boarding bridge with this type of structure is widely used and is also a relatively fast boarding auxiliary device. Its design is usually fully standardized as early as the structural design of buildings. We are a long-term manufacturer of boarding bridges. Welcome to inquire

.When it comes to fixed hydraulic boarding bridges, I believe

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,KararaAxle Co., Ltd, 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.

These are the options for hydraulic oil for mobile boarding bridges.

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 the following: (1) The brake of the elevator should be regularly inspected to see if its clearance is appropriate, as well as some other aspects, in order to ensure its flexibility and reliability in use. In addition, on the friction surface of the brake,KararaBoarding axle moving hydraulic pressure, it is necessary to check for any dirt, and if any, it should be cleaned in a timely manner. (2) For the part of the moving boarding bridge, it should be carried out in accordance with the specified requirements, and it should be comprehensive and sufficient without any omissions. However, the amount of oil should not be too much, as too much can also cause problems.

The platform side boarding bridge is directly installed at the front edge of the loading and unloading platform. There is no need to excavate or reserve pits on the loading and unloading operation platform, and there is basically no change to the building structure.

Home page recommendation.The platform side boarding bridge is directly installed at the front edge of the loading and unloading platform. There is no need to excavate or reserve pits on the loading and unloading operation platform, and there is basically no change to the building structure.

Open planning before placement makes it easy to clean up clutter.

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.

The platform side boarding bridge is directly installed at the front edge of the loading and unloading platform. There is no need to excavate or reserve pits on the loading and unloading operation platform, 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, motor not rotating, motor reverse, motor phase loss (motor not moving and buzzing),KararaFixed boarding bridge, 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 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.

Karara.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.

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

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.
