KartanisetaTheMonthly maintenance of hydraulic boarding bridges: check for wear on rollers,KartanisetaBoarding axle hydraulic mobile type, 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, 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.
The precautions during the use of hydraulic boarding bridges are hoped to be helpful to you.
Kartaniseta.Keep the hydraulic boarding bridge system clean: regularly replace the oil and filter. Good hydraulic oil contains various additives that can prevent oil deterioration or blockage of system components. However, the oil should be replaced regularly to ensure that the additives are effective. The filter can only absorb a limited number of dirt particles and other impurities from the oil. Replace the filter according to the recommended cycle to keep the system clean.
Open planning before placement makes it easy to clean up clutter.
.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.
Install drainage ditches on the ground near the pit of the simple boarding bridge, and take corresponding drainage measures for the top, surface, and foot of the slope, especially for the simple boarding bridge.
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.

(3) The steel wire rope in the elevator should be regularly checked for loose strands and broken wires, as it is frequently used and is also an important component. Therefore, there should be no careless inspection to avoid affecting the normal use of the elevator.
The electronic operation is very simple. With just one button, the air conditioning panel will automatically rise. Release the button adjust the plate to reduce itself, and the hinge is used on the truck.
build.Reasons 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,KartanisetaHydraulic boarding axle fixation, oil pump is empty, oil suction filter is blocked, 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.

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, 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).
conduct.
original.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,KartanisetaAutomatic boarding bridge, 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, you can choose the products of the manufacturer.
The outstanding characteristics of air suspension are good smoothness, less maintenance, long service life, 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.
Connection for. Enable forklift trucks to safely and quickly enter and exit transportation vehicles for loading and unloading operations.
Kartaniseta.During use, close attention should be paid to the condition of the equipment, and if there are any problems, the use should be stopped immediately.
The length of the electric hydraulic boarding bridge is generally about 10 meters, and the bearing weight varies depending on the tonnage. It is 10500mm for 6 tons, and 11300m for 10 tons. It is very suitable for placement on the ground in open spaces.
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?
