Hui CenMobile 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,Hui CenHydraulic boarding bridge, sticky or has foreign objects such as gravel. If found,Hui CenMobile Yard Ramps , it should be replaced in a timely manner; Add some oil to each part to extend the service life of the bearing. The hydraulic boarding bridge has a wide range of uses. Doing the above points well not only ensures your personal safety but also extends the service life of the equipment, making the boarding bridge better serve you.
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.
Hui Cen.B) When maintaining the hydraulic system, only clean plastic plugs can be used to seal the ends of the pipeline.
Do you know some of the working characteristics of hydraulic lifting boarding bridges? Today, I will take you to understand!
.The precautions during the use of hydraulic boarding bridges are hoped to be helpful to you.
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, strengthen dynamic management of equipment faults, 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.
When replacing hydraulic oil sometimes poor hydraulic oil can also cause noise on the hydraulic boarding bridge, as well as noise when the pump station enters the air.
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, 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 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, as a remedial measure, the mobile boarding bridge is incorrect
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.
Direct material.What should I pay attention to when choosing a boarding bridge? The selection and purchase of the boarding bridge involves paying attention to three issues, including its range of use, 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.
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.
It is strictly prohibited to apply excessive pile loads around the foundation pit.
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.
market price.During the excavation process of the foundation pit of the simple boarding bridge, and changes in the soil wall should be paid attention to at all times. If any abnormal phenomena such as cracks are found, construction must be suspended and reported to the superior for handling.
When the boarding axle is far away from the frame, 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,Hui CenDesign of boarding bridge, 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 it comes to fixed hydraulic boarding bridges, I believe
Hui Cen.Common&quo; Streamline” Open joint planning, with a welding area more than three times that of other traditional pipeline joints, greatly extending the service life and protection life.
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.
These are the options for hydraulic oil for mobile boarding bridges.
