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, 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.

Reason for the lifting table not lowering: The lowering valve is malfunctioning, and the lowering speed valve is out of adjustment. Solution: When pressing the lowering button, check if the lowering valve is energized. If there is no electricity, try to eliminate it; If there is electricity, troubleshoot the lowering valve itself or replace the lowering valve. The lowering valve should be kept clean.

Big Nova.Features: Utilizing a sleeve type drag chain structure to achieve high-altitude operation with telescopic arms, the platform vehicle can achieve 360° Rotating, both the work platform and the platform truck can be operated. The work platform truck can safely walk with the boom in any position,Big NovaHydraulic mobile boarding bridge, and the walking speed decreases with the rise of the lifting height.

During the excavation process of the foundation pit of the simple boarding bridge, and changes in the soil wall should be paid attention to at all times. If any abnormal phenomena such as cracks are found, construction must be suspended and reported to the superior for handling.

.Connection for. Enable forklift trucks to safely and quickly enter and exit transportation vehicles for loading and unloading operations.

The hydraulic boarding bridge is a specialized auxiliary equipment for achieving rapid loading and unloading of goods, and is our good helper. However, malfunctions during use are inevitable. What should we do when encountering a malfunction?

The pressure on the axle will reduce the service life of the boarding axle.

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, 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.

Features: Generally, domestic brands are the main products, with a lightweight boom design, which has a wide range of operations, lightweight flexibility, and high work efficiency. Large leg span, good stability, automatic detection of leg reverse force stop getting on if any leg loosens. When the chassis power system malfunctions, ensure that the platform car can be lowered and the rotating mechanism can be manually rotated. The cylinder rod is protected by a protective sheath, and the arm head is equipped with a dustproof device.

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.

Equipment maintenance.The pressure on the axle will reduce the service life of the boarding axle.

Connection for. Enable forklift trucks to safely and quickly enter and exit transportation vehicles for loading and unloading operations.

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.

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.

Inspection items.The slope of the electric hydraulic boarding bridge itself must have a certain slope to allow the forklift to enter the carriage for cargo loading and unloading. The length of the slope also varies from 7000mm to 7500mm, mainly considering safety and stability of use. For a long time, which is 20% higher than the market value! More than one ton is more expensive!

Advantages: Simple operation structure, safety and reliability, beautiful appearance, making it a high-altitude work equipment with better safety and work efficiency.

Open planning before placement makes it easy to clean up clutter.

Big Nova.It is strictly prohibited to apply excessive pile loads around the foundation pit.

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, you can choose the products of the manufacturer.

As an important part of the boarding bridge, the height can be adjusted according to the different vehicles of the goods,Big NovaFolding boarding bridge,Big NovaBoarding bridge platform, 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).
