Huvdop.The above content mainly shares the importance analysis of regular maintenance of mobile boarding bridges with everyone, hoping that everyone can take it seriously and not overlook it.
Monthly maintenance of hydraulic boarding bridges: check for wear on rollers, intermediate shafts and bearings,HuvdopTrain boarding 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.
.Is the boarding bridge easy to use? Those who have used the boarding bridge know that it is a very useful mechanical equipment, which brings great convenience to the logistics industry and some industrial factories that need to load and unload goods. Some enterprises also value the development prospects of the boarding bridge and set up factory boarding bridges. High priced and various specifications of boarding bridge manufacturers provide timely supply, with high cost-effectiveness, and has become the preferred brand for many wire products. Welcome to choose!
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.
When the hydraulic oil is insufficient, the hydraulic pump will produce suction phenomenon, causing air to enter the hydraulic oil and also producing high noise. 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 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.
The mobile boarding bridge is a type of forklift that directly loads and unloads goods from the ground to the truck
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.
Packaging strategy.Do you know some of the working characteristics of hydraulic lifting boarding bridges? Today, I will take you to understand!
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.
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?
It is strictly prohibited to apply excessive pile loads around the foundation pit.
Pursuit of excellence.When it comes to fixed hydraulic boarding bridges, I believe
Features: Generally, domestic brands are the main products, which has a wide range of operations, lightweight flexibility, and high work efficiency. Large leg span, good stability, automatic detection of leg reverse force, ensure that the platform car can be lowered and the rotating mechanism can be manually rotated. The cylinder rod is protected by a protective sheath,HuvdopBoarding bridge steel plate, and the arm head is equipped with a dustproof device.
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
Huvdop. 1. Before use, check the boarding bridge for obvious damage such as cracks and broken wires.
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, and replace it if it is damaged or severely worn.
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).
