EmenContainer 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,EmenLifting and disembarking bridge, 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, 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.
It is strictly prohibited to apply excessive pile loads around the foundation pit.
Emen.Application of hydraulic boarding bridges: Hydraulic boarding bridges can be widely used in docks, warehouses, load etc. The fixed boarding bridge is installed on the side of the cargo platform, flush with the ground and side of the cargo platform. The bridge deck of a fixed boarding bridge can tilt up and down, and its outer end can be higher or lower than the plane of the cargo platform, making it equal to the height of the carriage. There is a flip board at the top of the bridge, which automatically attaches to the edge of the carriage, ensuring a smooth passage between the cargo platform and the carriage.
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.
.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 11200m for 8 tons, it must be opened, otherwise the boarding bridge may be damaged.
These are the options for hydraulic oil for mobile boarding bridges.
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.
Usage scenario: Widely applicable for installation, maintenance, 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.
Connection for. Enable forklift trucks to safely and quickly enter and exit transportation vehicles for loading and unloading operations.
Where can I find it?.Monthly maintenance of hydraulic boarding bridges: check for wear on rollers,EmenBoarding axle manufacturer,EmenBoarding axle brand, intermediate shafts 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.

Common&quo; Work” Steel structure planning can withstand uniform pressure, reduce skeleton torque, and be more robust than other channel structures.
As we all know
Design brand.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?
Advantages: Simple operation structure, convenient operation, safety and reliability, beautiful appearance, making it a high-altitude work equipment with better safety and work efficiency.
Tighten the manual valve to close it.
Emen.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.
Check if the manual valve is open. When using, it must be opened, otherwise the boarding bridge may be damaged.
There is a flip plate at the top of the bridge deck, which is placed at the edge of the carriage to ensure a smooth transition between the passage and the carriage. Its advantages are as follows.
