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.
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.
B) When maintaining the hydraulic system, only clean plastic plugs can be used to seal the ends of the pipeline.
Monthly maintenance of hydraulic boarding bridges: check for wear on rollers, intermediate shafts and bearings,TeneyContainer loading and unloading bridge, 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, 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.
analysis.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.
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 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, but everyone still cares about the internal width, which is the width of the channel.
Slowly reverse and park the container under the lip at the front of the boarding bridge.
Credit guarantee.During construction,TeneyMobile boarding bridge, the factors of loading and unloading operations were not taken into account. The platform type loading and unloading bridge serves as a remedial solution and can also meet the requirements for loading and unloading operations into truck carriages. The platform type boarding bridge is also designed in various structural forms according to different on-site conditions. It can also be adjusted up (below the cargo platform) or down (below the cargo platform) within a certain range, which can meet the installation and use of most loading and unloading platforms. Is the boarding bridge easy to use? The boarding bridge is an auxiliary equipment used to bridge with the freight car and is designed to solve the height difference between the freight car and the ground. Suitable for fixed or mobile loading and unloading of goods, it is actually equivalent to a slope, allowing forklifts to smoothly enter the carriage to load and unload goods, requiring only one person to quickly load and unload goods, which is labor-saving.
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, 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.
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, and the bearing weight varies depending on the tonnage. It is 10500mm for 6 tons, 11200m for 8 tons, and 11300m for 10 tons. It is very suitable for placement on the ground in open spaces.
The hydraulic boarding bridge not only reduces labor intensity, but also doubles the efficiency of loading and unloading operations, accelerates logistics speed, also known as loading and unloading platforms.
