Cannes HydraulReason 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, check if the lowering valve is energized. If there is no electricity, try to eliminate it; If there is electricity, including its range of use, rated load, and other factors; Their understanding of the manufacturer of the boarding bridge, whether their enterprise qualifications, special equipment licenses are complete, 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, you can choose the products of the manufacturer.
Cannes .Features: Shear mechanical structure, working height generally ranging from 6 meters to 14 meters, high stability after lifting the platform, wide working platform vehicle and high load capacity, wide range of high-altitude work, suitable for multiple people working simultaneously. The power form can be selected according to different requirements (such as three-phase AC power supply, single-phase AC power supply, and internal combustion power supply). The manual hydraulic device can lift and retract normally in places with power outage or no power supply, increase the telescopic platform car and extend to necessary positions in case of insufficient length of the platform car, improving work efficiency.
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.
.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, 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 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.
Do you know some of the working characteristics of hydraulic lifting boarding bridges? Today, I will take you to understand!
As we all know
When the boarding axle is far away from the frame, the rod moves downward to open the air release valve, and the air in the air spring is atmospheric, and the body and frame then reduce to the original value. The dual or multi axle air suspension boarding axle can also be lifted on a single or multiple axle when unloaded or partially loaded, which can protect the raised tires. Simultaneously reducing incorrect guidance while reducing tire wear on other axles. In addition, there are other positive effects during the driving process. On the one hand, it generates appropriate stable force when unloaded and partially loaded, and on the other hand, it improves the adhesion of the drive shaft.
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.
Create brilliance.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, rain, and sunlight, 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.
During the excavation process of the foundation pit of the simple boarding bridge, collision of the support structure should be prevented, and changes in the soil wall should be paid attention to at all times. If any abnormal phenomena such as cracks are found,Cannes Design of boarding bridge, construction must be suspended and reported to the superior for handling.
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?
The hydraulic boarding bridge not only reduces labor intensity, accelerates logistics speed 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.
agent.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, 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.
The boarding bridge can be divided into two forms: a mobile boarding bridge and a fixed boarding bridge. A brief introduction to the application scope of a fixed boarding bridge and the use of a mobile boarding bridge: used for on-site vehicles without loading and unloading platforms or places that require mobile loading and unloading of goods. If there is no loading and unloading platform vehicle at the logistics site,Cannes The boarding bridge is movable, as a remedial measure, the mobile boarding bridge is incorrect
The safety valve of the mobile hydraulic boarding bridge can also generate high noise. When air is mixed into hydraulic oil, 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.
Cannes .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.
Portable hydraulic press boarding bridge: It is a widely used type, suitable for places where loading, unloading, and transportation are not fixed or moving; Mobile hydraulic press boarding bridge: suitable for fixed and immovable goods such as ports, cargo platforms, warehouses,Cannes Aluminum alloy boarding bridge, etc
The user department of the hydraulic boarding bridge should scientifically analyze the equipment and reasonably determine the investment in the equipment. At the same time, according to the characteristics of the work, professional personnel should be arranged to carry out on-site maintenance and upkeep to ensure that the lifting platform truck is always in normal operation, ensuring timely loading and unloading of supplied materials; The normal operation of equipment needs to be guaranteed by institutional measures, improve relevant management systems, monitor the status of key parts, and analyze the patterns of faults through maintenance; It is necessary to ensure the supply of maintenance accessories, establish a spare parts warehouse for vulnerable and commonly used parts, and purchase channels to avoid situations where inadequate preparation may lead to extended downtime and increased repair costs; Users should maintain a close relationship with survival manufacturers, strengthen the professional quality and professionalism of lifting platform maintenance personnel, so that they can handle faults in a short period of time.
