HartwanMobile 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, which reduces the lifespan of the boarding bridge. Therefore, 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.
Open the manual valve,HartwanManufacturing of boarding bridges, slowly lower the boarding bridge, and secure more than 90% of the lip plates at the bottom of the container.
Hartwan.The mobile boarding bridge suddenly loses control of the operating platform.
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,HartwanBoarding bridge platform, 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.
.Operation degree: There are two types of operations that can be used to raise and lower the boarding bridge. One is a manual pump station, which uses manual hydraulic lifting,HartwanPlatform boarding bridge, which is labor-intensive and somewhat labor-intensive. Advantages: It can be operated and used in any situation. Two types of electric pump stations use electric hydraulic lifting and lowering, which reduces labor intensity and saves labor. Disadvantage: Once the power is cut off, it will not be able to be used, a helmet must be worn.
Tighten the manual valve to close it.
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.
(5) Each mechanism in the elevator should be checked for normal operation and any noise or other malfunctions. If any, they should be promptly addressed and resolved. All wires and cables in the mobile boarding bridge should be checked for any damage or damage, and if any, they should be promptly wrapped or replaced with new ones.
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, 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.
It is strictly prohibited to apply excessive pile loads around the foundation pit.
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?
As we all know
High value.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.
Maintain the hydraulic system of the hydraulic boarding bridge. Keep the hydraulic oil of the hydraulic boarding bridge clean: Store the oil in a clean location, and be careful when changing or refueling. Only use a cleaning funnel equipped with a fine mesh filter to pour oil from the container into the oil tank. Of course, the oil you use should be the type recommended by the equipment manufacturer.
Reason 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, troubleshoot the lowering valve itself or replace the lowering valve. The lowering valve should be kept clean.
Hartwan.Operation degree: There are two types of operations that can be used to raise and lower the boarding bridge. One is a manual pump station, which uses manual hydraulic lifting, which reduces labor intensity and saves labor. Disadvantage: Once the power is cut off, it will not be able to be used, but now there are both manual and electric boarding bridges that are more convenient to use.
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.
Open planning before placement makes it easy to clean up clutter.
