Deng laohaiBoaTo 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.
The width of the boarding bridge also requires a certain width of its own. However, if the width is too small, it is not conducive to forklift loading and unloading of goods. If the width is too large, it can occupy a certain space, which is not necessary. So a reasonable width is necessary, usually the width of the electric hydraulic boarding bridge is 1800mm, 2000mm, and 2100mm. The width of the bridge is divided into internal width and total width. As we have already mentioned, and the total width mainly refers to the width of the guardrails on both sides plus the width of the passage. The total width can be ignored in use, but everyone still cares about the internal width, which is the width of the channel.

There is a lot of noise generated when using a mobile hydraulic boarding bridge. So, where are these noises caused? In fact, pump stations, steel cylinders, and steel equipment are all sources of noise. Today we will analyze for you: 1. 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, first check if there are any problems with the hydraulic pump station, motor, valve and fixing device, and if the noise is caused by its vibration.
.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?
When working on the hydraulic boarding bridge, the support legs must be extended,Deng laohaiHydraulic mobile boarding bridge, 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.
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.
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.
The above content mainly shares the importance analysis of regular maintenance of mobile boarding bridges with everyone, hoping that everyone can take it seriously and not overlook it.
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?
Quotation sheet.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.
Tighten the manual valve to close it.
The hydraulic boarding bridge not only reduces labor intensity, but also doubles the efficiency of loading and unloading operations, accelerates logistics speed, and achieves significant economic benefits. Hydraulic loading and unloading bridge is a specialized auxiliary equipment for fast loading and unloading of goods. Its height adjustment function allows a bridge to be built between the truck and the cargo platform in the warehouse. Forklifts and other transport vehicles can directly enter the truck for batch loading and unloading of goods, also known as loading and unloading platforms.
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, the manufacturer of the boarding axle has no turnover to avoid the price difference, which is 20% higher than the market value! More than one ton is more expensive!
packing.The reason for the natural descent of the hydraulic boarding bridge lifting platform is that the one-way valve is leaking,Deng laohaiFixed hydraulic boarding bridge, 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.
The seat belt needs to be inspected every six months, with a load of 225 kilograms. The test time is five minutes. After the test check whether the seat belt is broken or deformed, and keep records of the experiment. Any unqualified seat belts should be immediately stopped from use. Long term promotion of various brand products such as axle manufacturers, with complete designated products and guaranteed quality
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.
Deng laohai.Reason for the lifting table not lowering: The lowering valve is malfunctioning, 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.
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.
