LuanchengManufWhat is a hydraulic boarding axle? The hydraulic boarding bridge is a special auxiliary equipment used for fast loading and unloading of goods, 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?
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, troubleshoot the lowering valve itself or replace the lowering valve. The slide valve of the lowering valve must be kept clean and move flexibly.
Luancheng.There are the following: (1) The brake of the elevator should be regularly inspected to see if its clearance is appropriate, as well as some other aspects, in order to ensure its flexibility and reliability in use. In addition on the friction surface of the brake, and if any it is necessary to check for any dirt, it should be cleaned in a timely manner. (2) For the part of the moving boarding bridge, it should be carried out in accordance with the specified requirements, and it should be comprehensive and sufficient without any omissions. However, the amount of oil should not be too much, as too much can also cause problems.
1. Before use, check the boarding bridge for obvious damage such as cracks and broken wires.
.Slowly reverse and park the container under the lip at the front of the boarding bridge.
Reasons for the hydraulic boarding bridge lifting platform not lifting: low voltage, motor not rotating, motor phase loss (motor not moving and buzzing),LuanchengFixed hydraulic boarding bridge, 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.
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.
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?
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.
After the boarding bridge work is completed, all parts should be scrubbed and cleaned. When not working, the workbench should be lowered to a low position.
Quality assurance.When working in foundation pits or depths, a helmet must be worn.
When replacing hydraulic oil,LuanchengProcurement of fixed boarding bridges, sometimes poor hydraulic oil can also cause noise on the hydraulic boarding bridge, as well as noise when the pump station enters the air.
When working in foundation pits or depths, a helmet must be worn.
conduct.
Highly recommended.When working on the hydraulic boarding bridge, the support legs must be extended, 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.
The outstanding characteristics of air suspension are good smoothness, less maintenance, long service life, significant improvement in protection of cargo compared to steel plate suspension, and greatly reduced damage to the entire vehicle and road surface. The leaf spring produces different bending under different loads, so the distance between the whole vehicle and the ground is always changing. If the load is increased while keeping the spring unchanged, it will also reduce the natural frequency of the spring and even change the characteristics of the spring. The air spring is based on the compressibility of air. The air enclosed in the air bag is an element. Different air bag pressures of the air spring system balance different loads. When the height of the air bag is fixed, the distance between the car body and the road surface remains unchanged.
What should I pay attention to when choosing a boarding bridge? The selection and purchase of the boarding bridge involves paying attention to three issues, including its range of use, rated load, and other factors; Their understanding of the manufacturer of the boarding bridge, whether their enterprise qualifications,LuanchengMobile folding boarding bridge, special equipment licenses are complete, how many after-sales service outlets are there in the country, and whether they are timely; The important point is whether the quality is good or not, and whether the price is reasonable. If both of these situations are reasonable, you can choose the products of the manufacturer.
Luancheng.Open the manual valve slowly lower the boarding bridge, and secure more than 90% of the lip plates at the bottom of the container.
Open planning before placement makes it easy to clean up clutter.
The pressure on the axle will reduce the service life of the boarding axle.
