YunnanBoardingWhen working in foundation pits or depths, a helmet must be worn.
Install drainage ditches on the ground near the pit of the simple boarding bridge and take corresponding drainage measures for the top, surface, and foot of the slope, especially for the simple boarding bridge.
Yunnan.The mobile boarding bridge suddenly loses control of the operating platform.
Open the manual valve, slowly lower the boarding bridge, and secure more than 90% of the lip plates at the bottom of the container.
.The precautions during the use of hydraulic boarding bridges are hoped to be helpful to you.
Is the boarding bridge easy to use? Those who have used the boarding bridge know that it is a very useful mechanical equipment, which brings great convenience to the logistics industry and some industrial factories that need to load and unload goods. Some enterprises also value the development prospects of the boarding bridge and set up factory boarding bridges. High priced and various specifications of boarding bridge manufacturers provide timely supply, with high cost-effectiveness, and has become the preferred brand for many wire products. Welcome to choose!
Do you know some of the working characteristics of hydraulic lifting boarding bridges? Today, I will take you to understand!
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,YunnanBoarding bridge platform, 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.
Features: Generally, domestic brands are the main products, with a lightweight boom design, which has a wide range of operations, lightweight flexibility, and high work efficiency. Large leg span, stop getting on if any leg loosens. When the chassis power system malfunctions automatic detection of leg reverse force, 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.
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, 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.
assets.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, professional personnel should be arranged to carry out on-site maintenance and upkeep to ensure that the lifting platform truck is always in normal operation, 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, and analyze the patterns of faults through maintenance; It is necessary to ensure the supply of maintenance accessories, strengthen the professional quality and professionalism of lifting platform maintenance personnel,YunnanBoarding bridge steel plate, so that they can handle faults in a short period of time.
Monthly maintenance of hydraulic boarding bridges: check for wear on rollers, intermediate shafts and bearings, cylinder pins and bearings, boom hinge shafts and bearings, 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.
The hydraulic boarding bridge is a specialized auxiliary equipment for achieving rapid loading and unloading of goods, and is our good helper. However, malfunctions during use are inevitable. What should we do when encountering a malfunction?

Quality inspection report.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.
Advantages: The operation results are simpler, the operation is convenient, the stability is good, the safety is reliable, and has advantages. It is a common equipment for high-altitude operations.
It is strictly prohibited to apply excessive pile loads around the foundation pit.
Yunnan.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, if the width is too small, 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, 2000mm 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.
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.
