NivohainMobileReasons for the hydraulic boarding bridge lifting platform not lifting: low voltage, 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,NivohainDengCheQiao Manufacturing Factory, 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,NivohainMobile Yard Ramps , 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.
The user department of the hydraulic boarding bridge should scientifically analyze the equipment and reasonably determine the investment in the equipment. At the same time,NivohainDesign of mobile boarding bridge, according to the characteristics of the work, professional personnel should be arranged to carry out on-site maintenance and upkeep to ensure that the lifting platform truck is always in normal operation, ensuring timely loading and unloading of supplied materials; The normal operation of equipment needs to be guaranteed by institutional measures, monitor the status of key parts, and analyze the patterns of faults through maintenance; It is necessary to ensure the supply of maintenance accessories, and purchase channels to avoid situations where inadequate preparation may lead to extended downtime and increased repair costs; Users should maintain a close relationship with survival manufacturers, strengthen the professional quality and professionalism of lifting platform maintenance personnel, so that they can handle faults in a short period of time.
Nivohain.The natural frequency of the air spring is stable, so its performance is also stable, which means that the air spring is closer to the ideal state. How does the air spring change the air pressure in the airbag with different loads to achieve the goal of keeping the distance between the car body and the road surface unchanged. The height valve 3 shown serves this purpose. The height valve is fixed on the frame and the connecting rod is connected to the hydraulic boarding bridge. The height valve has two valves, namely, the charging valve for air supply and the air release valve for air supply. These two valves are both connected by the rod. When the car load increases, the boarding bridge moves close to the frame, the connecting rod rises. When the connecting rod mechanism opens the charging valve compressed air enters the air spring, and the frame and body rise until the height of the body is restored.
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.
.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, special equipment licenses are complete, how many after-sales service outlets are there in the country, how about their after-sales service attitude, 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, 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.
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.
Slowly reverse and park the container under the lip at the front of the boarding bridge.
Applicable scenario: Suitable for mobile high-altitude operations such as setting and inspection of high-altitude equipment in various industries.
Hydraulic boarding bridges should strictly adhere to the principle of being overweight, as overloading may cause damage to objects; Working on a lifting platform without protective barriers may cause personnel to fall and cause casualties.
discount. 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, we should regularly clean the safety valve, and replace it if it is damaged or severely worn.
conduct.
For slopes that are unstable or unstable after earthwork excavation, top-down segmented trench jumping should be adopted based on the geological characteristics and possible situations of the slope, and reverse construction or partial reverse construction should be carried out in a timely manner. It is strictly prohibited to excavate and explode indiscriminately.
Information recommendation.For slopes that are unstable or unstable after earthwork excavation, top-down segmented trench jumping should be adopted based on the geological characteristics and possible situations of the slope, and reverse construction or partial reverse construction should be carried out in a timely manner. It is strictly prohibited to excavate and explode indiscriminately.
The seat belt needs to be inspected every six months, with a load of 225 kilograms. The test time is five minutes. After the test, check whether the seat belt is broken or deformed, and keep records of the experiment. Any unqualified seat belts should be immediately stopped from use. Long term promotion of various brand products such as axle manufacturers, with complete designated products and guaranteed quality
The pressure on the axle will reduce the service life of the boarding axle.
Nivohain.The pressure on the axle will reduce the service life of the boarding axle.
During excavation, if unidentifiable items or unforeseeable situations are found, the operation should be stopped in a timely manner and reported to the person in charge of the hydraulic boarding bridge for handling. The fixed boarding bridge is an auxiliary equipment for loading and unloading in conjunction with the storage platform. This equipment is integrated with the platform and can be adjusted up or down according to the different heights of the truck carriage, making it convenient for forklifts to enter the carriage. The equipment adopts an imported hydraulic pump station with anti rolling skirts on both sides, making work safer and improving work efficiency.
Portable hydraulic press boarding bridge: It is a widely used type, suitable for places where loading, unloading, and transportation are not fixed or moving; Mobile hydraulic press boarding bridge: suitable for fixed and immovable goods such as ports, cargo platforms, etc
