GdyniaThe boarding bridgeDeformation control

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.

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, 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.

Gdynia.C) When maintaining hydraulic components, the workbench must be absolutely clean. Check the condition of the tools used. They should also be very clean.

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

.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.

The hydraulic boarding bridge not only reduces labor intensity, but also doubles the efficiency of loading and unloading operations, accelerates logistics speed, also known as loading and unloading platforms.

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 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.

Reason for the lifting table not lowering: The lowering valve is malfunctioning, and the lowering speed valve is out of adjustment. Solution: When pressing the lowering button check if the lowering valve is energized. If there is no electricity, try to eliminate it; If there is electricity, troubleshoot the lowering valve itself or replace the lowering valve. The lowering valve should be kept clean.

Applicable scenarios: municipal road engineering inspection, street lamp maintenance, branch construction, signboard maintenance, etc.

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.

Honesty is the foundation.　　1. Before use,GdyniaMovable hydraulic boarding bridge, check the boarding bridge for obvious damage such as cracks and broken wires.

Do you know some of the working characteristics of hydraulic lifting boarding bridges? Today I will take you to understand!

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

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, 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.

Quality assurance.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?

Mobile boarding bridge is a cargo loading and unloading auxiliary equipment used in conjunction with forklifts, which can adjust the height according to the height of the car carriage. Forklifts can directly enter the interior of the carriage for batch loading and unloading of goods,GdyniaMobile cllimbing, and can achieve rapid loading and unloading of goods with only one person working. It enables enterprises to reduce a large amount of labor, improve work efficiency, and obtain greater economic benefits.

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.

Gdynia.Tighten the manual valve to close it.

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,GdyniaContainer loading and unloading bridge, 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, clean the one-way valve. Check if the lowering valve has power. If there is power, troubleshoot the lowering valve itself or replace the lowering valve. The slide valve of the lowering valve must be kept clean and move flexibly.
