Check if the manual valve is open. When using, it must be opened, otherwise the boarding bridge may be damaged.Install a m high protective railing around the foundation pit of the simple boarding bridge, with a distance of no less than m from the protective railing to the foundation pit. The mobile boarding bridge only requires a single person to operate, without the need for power supply,ShijingshanAxle Co., Ltd, and can achieve safe and fast loading and unloading of goods. Mobile boarding bridges are widely used in cargo platforms and mobile loading and unloading sites without loading and unloading equipment. They are auxiliary equipment for cargo loading and unloading that is used in conjunction with forklifts. The sequence of earthwork excavation must comply with design conditions and follow' Trenching support, support first and then excavation, layered excavation, no overbreak&rquote; The principle of.Shijingshan,Used for cargo platforms and mobile loading and unloading sites without loading and unloading equipment, it is a cargo loading and unloading auxiliary equipment used in conjunction with forklifts. With the help of hydraulic loading bridges, forklifts can directly enter the interior of car containers for bulk loading and unloading operations. It only needs single person operation and no power supply to realize safe and fast loading and unloading of goods, double the efficiency of loading and unloading operations speed up the flow of materials, and obtain greater economic benefits.Reasons for the hydraulic boarding bridge lifting platform not lifting: low voltage, motor not rotating, 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,ShijingshanHuangshi boarding bridge, 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,ShijingshanFolding boarding bridge, 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 % 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.Pando,Common&quo; Work” Steel structure planning can withstand uniform pressure, reduce skeleton torque, and be more robust than other channel structures.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.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, it must be opened, otherwise the boarding bridge may be damaged.On a moving steel structure slope, forklifts can also directly enter the interior of truck carriages for bulk loading and unloading operations. Fast loading and unloading of goods can be achieved with only one person operating and without the need for power supply.Tighten the manual valve to close it.supply,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 mm to mm. The hydraulic lifting stroke height ranges from mm to mm, and the height of the electric hydraulic boarding bridge itself plus the stroke height is mm, which can be met by almost all freight vehicles (with a general vehicle height of ).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, construction must be suspended and reported to the superior for handling.Hydraulic boarding bridges should strictly adhere to the principle of being overweight, 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?supply,Common&quo; Streamline” Open joint planning, with a welding area more than three times that of other traditional pipeline joints, greatly extending the service life and protection life.Fixed loading and unloading bridge: The fixed loading and unloading bridge is a specialized auxiliary equipment for achieving rapid loading and unloading of goods. Its height adjustment function uses a bridge between the truck and the cargo platform in the warehouse, and forklifts and other vehicles can move and load goods in batches inside the truck. Only one person can work to achieve rapid loading and unloading of goods. It enables enterprises to reduce a large amount of labor, improve work efficiency and obtain greater economic benefits.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.Shijingshan,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.Check if the manual valve is open. When using, it must be opened otherwise the boarding bridge may be damaged.When confirming that the lip is fixed to the container, pull out the hook to hook it into the container, tighten the chain to ensure that it does not loosen, and press the brake blocks on both sides. The boarding bridge is already a very visible structural form in modern logistics sites. It is the point and endpoint of the enterprise logistics chain, and a loading and unloading operation platform for enterprises to quickly and safely turnover products and goods. The height of the loading and unloading operation platform is fixed, but there is always a certain height difference or gap between the transportation vehicles and the loading and unloading platform due to the height of the carriage. Causing the forklift to be unable to enter and exit the transportation vehicle for direct loading and unloading of goods. Use the boarding bridge to provide reliable connections. Enable forklift trucks to safely and quickly enter and exit transportation vehicles for loading and unloading operations.
