Install a 5m high protective railing around the foundation pit of the simple boarding bridge, with a distance of no less than 1m from the protective railing to the foundation pit. The mobile boarding bridge only requires a single person to operate, and can achieve safe and fast loading and unloading of goods. Mobile boarding bridges are widely used in cargo platforms and mobile loading and unloading sites without loading and unloading equipment. They are auxiliary equipment for cargo loading and unloading that is used in conjunction with forklifts. The sequence of earthwork excavation must comply with design conditions and follow" Trenching support, layered excavation, no overbreak&rquote; The principle of.
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.
Taocheng.The appearance of the hydraulic boarding bridge provided by Qiaolai to customers, and the demand for boarding bridges is also increasing. However, there are not many manufacturers of corresponding boarding bridges. Many boarding bridge companies are leather bag companies, and they do not produce them themselves, resulting in high prices. What is important is that they do not have a good understanding of the technology of car booths, and there are often deviations when passing on the technical requirements of direct customers to the manufacturers. Therefore, customers who purchase boarding bridges can directly find professional manufacturers. When choosing a boarding bridge, the first thing to consider is the range of use, frequency of work, utilization,TaochengFixed hydraulic boarding bridge, rated weight, and other factors of the product and choose a boarding bridge that is suitable for the requirements of the unit. Conduct market research based on the proposed technical parameters. The first condition for selecting a supplier is to consider the manufacturer of the boarding axle, and then the after-sales service capability. As long as it is a fixed boarding bridge with good product quality, excellent performance, and complete equipment, it can be chosen at a reasonable price. Long term promotion of axle manufacturer, 20 year old brand, 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).
.The hydraulic lifting boarding bridge is a specialized auxiliary equipment for fast loading and unloading of goods. Its height adjustment function allows a bridge to be built between the truck and the cargo platform in the warehouse. Forklifts and other handling vehicles can directly enter the truck for batch loading and unloading of goods, and single person operations can achieve fast loading and unloading of goods. Reduce a large amount of labor, improve work efficiency, and achieve greater economic benefits for enterprises.
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,TaochengMobile boarding axle hydraulic pressure, 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,TaochengThe boarding bridge, 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.
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?
During excavation, 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.
When conducting high-altitude operations on dangerous edges such as roofs, suspension bridges, slopes, guardrails or safety nets should be installed on the side facing the air, or safety belts or ropes should be used.
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, troubleshoot the lowering valve itself or replace the lowering valve. The slide valve of the lowering valve must be kept clean and move flexibly.
Quotation sheet.The pressure on the axle will reduce the service life of the boarding axle.
During excavation clean the one-way valve. Check if the lowering valve has power. If there is power, 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.
The precautions during the use of hydraulic boarding bridges are hoped to be helpful to you.
To ensure that the hydraulic boarding bridge is in good condition, it should be checked in advance before use, mainly including whether the buttons are effective; Whether the power cord and socket are intact; Whether the oil pipeline is intact; The stability of the guardrail; The tightness of bolts at each junction point; The appearance quality is intact. But when the power is turned on and the indicator light is on, press the up button the motor rotates but the lifting table does not rise. This may be due to the reverse connection of the three-phase power supply and the motor reversing. Only the power supply needs to be corrected, so it is not a major problem.
reform.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.
The natural frequency of the air spring is stable, so its performance is also stable, which means that the air spring is closer to the ideal state. How does the air spring change the air pressure in the airbag with different loads to achieve the goal of keeping the distance between the car body and the road surface unchanged. The height valve 3 shown serves this purpose. The height valve is fixed on the frame and the connecting rod is connected to the hydraulic boarding bridge. The height valve has two valves, namely, the charging valve for air supply and the air release valve for air supply. These two valves are both connected by the rod. When the car load increases, the boarding bridge moves close to the frame, the connecting rod rises. When the connecting rod mechanism opens the charging valve, compressed air enters the air spring, and the frame and body rise until the height of the body is restored.
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?
Taocheng.conduct.
There is a flip plate at the top of the bridge deck, which is placed at the edge of the carriage to ensure a smooth transition between the passage and the carriage. Its advantages are as follows.
Embedded boarding bridge, 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
