LamarBoarding 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.
Lamar.B) When maintaining the hydraulic system, only clean plastic plugs can be used to seal the ends of the pipeline.
The correct operation of the hydraulic boarding bridge is good maintenance, hoping to bring more help to everyone.
.Install drainage ditches on the ground near the pit of the simple boarding bridge,LamarLogistics boarding bridge, and take corresponding drainage measures for the top, surface, and foot of the slope, especially for the simple boarding bridge.
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.
To ensure that the hydraulic boarding bridge is in good condition, it should be checked in advance before use, mainly including whether the buttons are effective; Whether the power cord and socket are intact; Whether the oil pipeline is intact; The stability of the guardrail; The tightness of bolts at each junction point; The appearance quality is intact. But when the power is turned on and the indicator light is on, press the up button, the motor rotates but the lifting table does not rise. This may be due to the reverse connection of the three-phase power supply and the motor reversing. Only the power supply needs to be corrected, so it is not a major problem.
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.
Usage scenario: Widely applicable for installation, and high-altitude work platform vehicles in industries such as municipal administration, electricity, streetlights, advertising, communication, photography, landscaping, transportation, docks, airports and ports, and large industrial and mining enterprises.
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,LamarFolding boarding bridge, we should regularly clean the safety valve, and replace it if it is damaged or severely worn.
Marketing Department.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,LamarBoarding bridge steel plate, 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.
Check if the manual valve is open. When using, it must be opened, otherwise the boarding bridge may be damaged.
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.
Reasons for the hydraulic boarding bridge lifting platform not lifting: low voltage, 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.
Information recommendation.Portable hydraulic press boarding bridge: It is a widely used type, unloading, and transportation are not fixed or moving; Mobile hydraulic press boarding bridge: suitable for fixed and immovable goods such as ports, cargo platforms, warehouses, etc
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, and take corresponding drainage measures for the top, surface, and foot of the slope especially for the simple boarding bridge.

This may be due to the reverse connection of the three-phase power supply and the motor reversing. Only the power supply needs to be corrected, so it is not a major problem.
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, which can effectively prevent the adjustment board from falling down and keep the pressure foot in a safe state.
