FotLogistics boarding bridgeNeed to consider the balance of various interests

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.

The length of the electric hydraulic boarding bridge is generally about 10 meters, and the bearing weight varies depending on the tonnage. It is 10500mm for 6 tons, and 11300m for 10 tons. It is very suitable for placement on the ground in open spaces.

Fot.Features: Utilizing a sleeve type drag chain structure to achieve high-altitude operation with telescopic arms,FotMounted axle hydraulic fixed type, the platform vehicle can achieve 360° Rotating both the work platform and the platform truck can be operated. The work platform truck can safely walk with the boom in any position, and the walking speed decreases with the rise of the lifting height.

When working in foundation pits or depths, a helmet must be worn.

.Hydraulic boarding bridges should strictly adhere to the principle of being overweight, as overloading may cause damage to objects; Working on a lifting platform without protective barriers may cause personnel to fall and cause casualties.

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,FotHydraulic mobile boarding bridge, 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.

　　1. Before use, check the boarding bridge for obvious damage such as cracks and broken wires.

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, which is the width of the channel.

(3) The steel wire rope in the elevator should be regularly checked for loose strands and broken wires, as it is frequently used and is also an important component. Therefore, there should be no careless inspection to avoid affecting the normal use of the elevator.

The correct operation of the hydraulic boarding bridge is good maintenance, and how to operate it correctly. Let me briefly introduce the operating steps of the hydraulic boarding bridge, hoping to bring more help to everyone.

original.When confirming that the lip is fixed to the container, pull out the hook to hook it into the container, tighten the chain to ensure that it does not loosen, and press the brake blocks on both sides. 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, 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.

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

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.

Embedded boarding bridge, 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

Total quality assurance.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.

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, what are the abnormalities that can be observed during the use of the mobile 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.

Fot.To ensure that the hydraulic boarding bridge is in good condition, it should be checked in advance before use,FotHydraulic flow boarding bridge, 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.

As an important part of the boarding bridge, 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, 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).

Open the manual valve, slowly lower the boarding bridge, and secure more than 90% of the lip plates at the bottom of the container.
