GrujonzMovableReasons 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.
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.
Grujonz.There are many types of boarding bridges and their respective roles and application fields are also different. Hydraulic boarding bridges, fixed boarding bridges, and mobile boarding bridges are currently common and advantageous equipment on the market playing a huge role in their respective fields. Below, we will first analyze the development trend of mobile boarding bridges: mobile hydraulic boarding bridges are a good helper for loading and unloading goods on forklifts. Compared to pneumatic tires, mobile boarding bridges are equipped with solid tires with low starting resistance, simple structure, convenient use and maintenance, no need for inflation, no hidden dangers of air leakage and tire explosion. And solid tires have good safety durability, puncture resistance, tear resistance, and economy.
Connection for. Enable forklift trucks to safely and quickly enter and exit transportation vehicles for loading and unloading operations.
.Tighten the manual valve to close it.
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 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, LtdBriefly describe several precautions for use' >
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, 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.
B) When maintaining the hydraulic system, only clean plastic plugs can be used to seal the ends of the pipeline.
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, how many after-sales service outlets are there in the country, how about their after-sales service attitude, and whether they are timely; The important point is whether the quality is good or not, and whether the price is reasonable. If both of these situations are reasonable, the air conditioning panel will automatically rise. Release the button, adjust the plate to reduce itself, and the hinge is used on the truck.
When replacing hydraulic oil, sometimes poor hydraulic oil can also cause noise on the hydraulic boarding bridge, as well as noise when the pump station enters the air.
There is a lot of noise generated when using a mobile hydraulic boarding bridge. So, where are these noises caused? In fact, pump stations, steel cylinders,GrujonzBoarding axle brand, and steel equipment are all sources of noise. Today we will analyze for you: 1. 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. After hearing the noise from the hydraulic boarding bridge, first check if there are any problems with the hydraulic pump station, motor, valve,GrujonzWarehouse boarding bridge, and fixing device, and if the noise is caused by its vibration.
Potential development.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,GrujonzMobile lifting boarding bridge, 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.
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, on the friction surface of the brake, 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 precautions during the use of hydraulic boarding bridges are hoped to be helpful to you.
Grujonz.Do you know some of the working characteristics of hydraulic lifting boarding bridges? Today, if unidentifiable items or unforeseeable situations are found, the operation should be stopped in a timely manner and reported to the person in charge of the hydraulic boarding bridge for handling. The fixed boarding bridge is an auxiliary equipment for loading and unloading in conjunction with the storage platform. This equipment is integrated with the platform and can be adjusted up or down according to the different heights of the truck carriage, making it convenient for forklifts to enter the carriage. The equipment adopts an imported hydraulic pump station with anti rolling skirts on both sides, making work safer and improving work efficiency.
Common&quo; Work” Steel structure planning can withstand uniform pressure, reduce skeleton torque, and be more robust than other channel structures.
