DuisburgHydrauDo you know some of the working characteristics of hydraulic lifting boarding bridges? Today, I will take you to understand!
The hydraulic lifting boarding 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 handling vehicles can directly enter the truck for batch loading and unloading of goods, and single person operations can achieve fast loading and unloading of goods. Reduce a large amount of labor, improve work efficiency, and achieve greater economic benefits for enterprises.
Duisburg.Advantages: Widely used high-altitude work equipment, stable and safe, and its height adjustment function can build a bridge between the truck and the warehouse platform. What are the operational steps we take during 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.
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?
During use, and if there are any problems the use should be stopped immediately.
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,DuisburgMovable hydraulic boarding bridge, 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 emergence of mobile boarding bridges solves the problem of cargo loading and unloading auxiliary boarding equipment for forklifts entering the ground of freight containers and the height difference between trucks. The mobile boarding bridge can adjust the height of the mobile boarding bridge to be level with the height of the container according to the height of the truck container, achieving rapid loading and unloading of goods and improving the efficiency of cargo loading and unloading. So, what are the abnormalities that can be observed during the use of the mobile boarding bridge?
Connection for. Enable forklift trucks to safely and quickly enter and exit transportation vehicles for loading and unloading operations.
Safety production.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.
Shake the handle to raise the boarding bridge to the height of the container.
There are three movable boards on both sides of the air conditioning board, which can effectively prevent the adjustment board from falling down and keep the pressure foot in a safe state.
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, and sunlight, which reduces the lifespan of the boarding bridge. Therefore, the maintenance of the boarding bridge is very important. When it rains, motor not rotating, motor reverse, motor phase loss (motor not moving and buzzing), indicator light on, press the up button, motor rotates but lifting platform does not rise, lowering valve is open, overflow valve pressure is low, oil level is too low, oil pump is empty, oil suction filter is blocked, oil suction section is leaking, and two phases in the three-phase line are arbitrarily changed; Solution: Check the starter potential during motor load operation. Voltage hydraulic range allowed± １０％； Check the motor and circuit; Check the circuit breaker and motor wiring; When the lowering button is released, use a voltmeter to check whether the lowering valve is energized. If there is no power, check the circuit and eliminate the fault; If there is electricity, eliminate the malfunction of the lowering valve itself. The slide valve of the lowering valve must be kept clean and move flexibly. Readjust the overflow valve. Adjust at 100% rated load; Fill up the hydraulic oil; Clean the filter; Check the oil suction pipe and joints; Tighten the joint and replace it if necessary.
For the safety performance of high-altitude work platform vehicles, it is necessary to have production technology, scientific processes, and strict management to ensure production. When in use, people, the environment, and machines are the three major links of high-altitude operations, and safety is the basic condition to ensure the smooth progress of high-altitude operations. In the following text, Jiuyi briefly describes the precautions for using high-altitude operation platform vehicles: high-altitude operators must hold a health certificate. Individuals with mental illness, hypertension, or mental illness are not allowed to engage in high-altitude work tasks. Staff are not allowed to engage in high-altitude work while drinking alcohol or feeling mentally drained.
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,DuisburgTruck boarding bridge, 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.
Duisburg.Tighten the manual valve to close it.
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.
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.
