There is a flip plate at the top of the bridge deck, making them less prone to damage. They have stronger adaptability to the environment. Solid rubber tires have higher load-bearing capacity than ordinary pneumatic rubber tires of the same model, are more wear-resistant, have a longer service life, and are more cost-effective. This is why mobile boarding bridges are now equipped with solid rubber tires.
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, construction must be suspended and reported to the superior for handling.
.During construction, 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, 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.
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.
Nowadays, the electric hydraulic boarding bridge has become a loading and unloading tool used by many companies. Compared to many friends, I am still not very familiar with electric hydraulic boarding bridges. Below, the editor will explain the product parameters and specifications related to the length, slope, and height of the electric hydraulic boarding bridge.
Install drainage ditches on the ground near the pit of the simple boarding bridge, and take corresponding drainage measures for the top, surface, such as working in highly corrosive especially for the simple boarding bridge.
Usage environment: Able to adapt to specific working environments, dusty, high-temperature, and low-temperature environments.
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.
Installation conditions.There is a lot of noise generated when using a mobile hydraulic boarding bridge. So, where are these noises caused? In fact, pump stations, steel cylinders, and steel equipment are all sources of noise. Today we will analyze for you: 1. 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. After hearing the noise from the hydraulic boarding bridge, first check if there are any problems with the hydraulic pump station, motor, valve, and fixing device, and if the noise is caused by its vibration.
Common&quo; Streamline” Open joint planning with a welding area more than three times that of other traditional pipeline joints, slowly lower the boarding bridge greatly extending the service life and protection life.
Open the manual valve, and secure more than 90% of the lip plates at the bottom of the container.
Slowly reverse and park the container under the lip at the front of the boarding bridge.
Quality Assurance.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).
High altitude work platform vehicles are mainly divided into four types: scissor type, straight arm type, curved arm type, and vehicular type. Scissor fork type high altitude work platform vehicles.
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, 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.
Avery on the Seine.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.
