XiqingMobile boarding bridgeWhat are the changes in the market?

When working on the hydraulic boarding bridge, the support legs must be extended, and the support leg bolts must be adjusted to ensure that the lifting platform is stably stressed on the support legs and kept horizontal; During the lifting process and in the lifting state, the lifting platform must not be moved, and it is strictly prohibited to shake on the lifting platform. If there is an abnormal sound during the operation of the hydraulic boarding bridge, it should be stopped immediately for inspection to avoid causing serious damage to the lifting platform; Before use, check whether the electrical equipment is normal; All shaft pin oil holes must be oiled before each use. Before use, it is necessary to perform no-load lifting and check whether the hydraulic system is normal; The load of the workbench should not exceed the rated value, and it should not be subjected to intense manual shaking; The hydraulic oil in the oil tank must be replaced every 500 hours of operation.

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.

Xiqing.Check the hydraulic oil quality and level. When the lifting platform is raised to a high position, the hydraulic oil level should be 40-50 millimeters higher than the bottom of the oil tank. When the color of the hydraulic oil darkens, the oil becomes sticky, or there are foreign objects such as gravel in the oil, the hydraulic oil should be replaced in a timely manner. The hydraulic system of the lifting platform should be checked for hydraulic and pipeline connections. If the pipeline is damaged it should be replaced immediately; When there is looseness in the connection part, tighten the pipe joint.

During use, close attention should be paid to the condition of the equipment, and if there are any problems, the use should be stopped immediately.

.The hydraulic boarding bridge not only reduces labor intensity, but also doubles the efficiency of loading and unloading operations, accelerates logistics speed, 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.

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 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.

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, and there is basically no change to the building structure.

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, or has foreign objects such as gravel. If found, making the boarding bridge better serve you.

The natural frequency of the air spring is stable, so its performance is also stable,XiqingWarehouse boarding bridge, 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.

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

Inspection environment.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,XiqingManufacturing of boarding bridges,XiqingTelescopic 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.

Portable hydraulic press boarding bridge: It is a widely used type, suitable for places where loading, and transportation are not fixed or moving; Mobile hydraulic press boarding bridge: suitable for fixed and immovable goods such as ports, cargo platforms, warehouses, etc

For slopes that are unstable or unstable after earthwork excavation, top-down segmented trench jumping should be adopted based on the geological characteristics and possible situations of the slope, and reverse construction or partial reverse construction should be carried out in a timely manner. It is strictly prohibited to excavate and explode indiscriminately.

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, 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.

Good quality.Slowly reverse and park the container under the lip at the front of the boarding bridge.

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.

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, 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.

Xiqing.For slopes that are unstable or unstable after earthwork excavation, top-down segmented trench jumping should be adopted based on the geological characteristics and possible situations of the slope, 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.

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.
