SOSTAutomobileThe 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, 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.
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.
SOST.The outstanding characteristics of air suspension are good smoothness, less maintenance, long service life, significant improvement in protection of cargo compared to steel plate suspension, and greatly reduced damage to the entire vehicle and road surface. The leaf spring produces different bending under different loads, so the distance between the whole vehicle and the ground is always changing. If the load is increased while keeping the spring unchanged, it will also reduce the natural frequency of the spring and even change the characteristics of the spring. The air spring is based on the compressibility of air. The air enclosed in the air bag is an element. Different air bag pressures of the air spring system balance different loads. When the height of the air bag is fixed, the distance between the car body and the road surface remains unchanged.
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.
.Nowadays, the electric hydraulic boarding bridge has become a loading and unloading tool used by many companies. Compared to many friends I am still not very familiar with electric hydraulic boarding bridges. Below, the editor will explain the product parameters and specifications related to the length, slope, and height of the electric hydraulic boarding bridge.
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
As we all know
What is a hydraulic boarding axle? The hydraulic boarding bridge is a special auxiliary equipment used for fast loading and unloading of goods, and its height adjustment function can build a bridge between the truck and the warehouse platform. What are the operational steps we take during use?
Function: Convenient unloading, strong stability, and low maintenance cost. Suitable for various vehicles on loading and unloading sites and places with relatively busy traffic. Loading and unloading platform vehicles, lifting platform vehicles, and unloading platform vehicles: Anti slip device: This device is welded from steel plates, which can effectively achieve anti slip function and is reliable.
The width of the boarding bridge also requires a certain width of its own. However, if the width is too small,SOSTHydraulic boarding bridge, 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,SOSTMovable hydraulic boarding bridge, 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.
Test method.The hydraulic system adopts imported Italian brand products, inclined plate, top, can be adjusted smoothly. The height adjustment plate is a selected decorative plate and profile, with a long service life. Various qualified manufacturers of boarding bridges are welcome to inquire by phone and sincerely invite cooperation!
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, lowering valve is open motor rotates but lifting platform does not rise, 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 hydraulic boarding bridge not only reduces labor intensity, but also doubles the efficiency of loading and unloading operations, and achieves significant economic benefits. Hydraulic loading and unloading 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 transport vehicles can directly enter the truck for batch loading and unloading of goods, also known as loading and unloading platforms.
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?
where.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.
Check the rollers intermediate shafts, and bearings; Oil cylinder pin and bearing; Equality and wear of the hinge shaft and bearings of the boom; Add oil to the above components for maintenance of outdoor elevators and factory elevators. Extend the service life of bearings. Professional axle manufacturers and other special products, 20 year old brand, with price advantages and guaranteed quality
To ensure that the hydraulic boarding bridge is in good condition, it should be checked in advance before use,SOSTMobile boarding axle hydraulic pressure, 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.
SOST.The width of the boarding bridge also requires a certain width of its own. However, 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.
