Vibration acoustic method: Vibration acoustic instruments detect the vibration and noise of hydraulic systems， and identify the wear (a basic type of component failure) and technical status of hydraulic components according to the laws of vibration acoustics. Based on this， diagnose the cause location， degree， nature， and development trend of faults. Nowadays， with the rapid development of the logistics industry the demand for logistics equipment is becoming increasingly weak， and auxiliary improvements such as fixed hydraulic boarding bridges and fixed lifting channels， as well as the increase in loading and unloading equipment usage， have been made. Some manufacturers have now achieved export to foreign countries!
The overall module of the water inlet pipe of the hydraulic boarding bridge must have a reasonable hydraulic system during the application process， so that the equipment has excellent airtightness and a long service life， and the height of the equipment is fixed

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， about % of the faults in the fixed axle hydraulic system are caused by oil infection. Therefore， various analysis methods are used to identify the composition and specific gravity of pollutants in the oil， which can diagnose the faults and degree of hydraulic oil pollution in the fixed axle hydraulic system. The car mounted hedge trimmer improves the trimming quality，HuanghuaHydraulic fixed boarding axle， improves work efficiency，HuanghuaMobile hydraulic lifting boarding bridge， and has a times higher rate than manual trimming， without any safety hazards; Can form different plant shapes. Used for pruning road greening plants.
When using the boarding bridge for loading and unloading， and do not be overweight. If overweight occurs， it will make the hydraulic system struggle during the lifting process， and even cause deformation of the hydraulic cylinder body， resulting in gaps and oil leakage outward. This requires finding a professional manufacturer for maintenance， such as Shanghai Niuli Machinery. If the deformation is severe， the only option is to replace it with a new one.
The fixed hydraulic boarding bridge has three fundamental elements: purification， overheating， and air intake. There is a close internal connection between these three unfavorable factors， there are certain strict requirements for the quality and material selection of height adjustment plates to avoid the occurrence of defective materials as the fixed hydraulic boarding bridge is used to complete the rapid loading and unloading of goods through height adjustment plates， which will result in unexpected loss of performance in the application process.

When using the boarding bridge for loading and unloading load and unload according to the rated load， and do not be overweight. If overweight occurs， it will make the hydraulic system struggle during the lifting process， and even cause deformation of the hydraulic cylinder body， resulting in gaps and oil leakage outward. This requires finding a professional manufacturer for maintenance such as Shanghai Niuli Machinery. If the deformation is severe， the only option is to replace it with a new one.
The hydraulic boarding bridge is mainly made of anti slip thick steel plates during the production and manufacturing process， and all equipment can provide good anti slip characteristics to a certain level in operation and application. The hydraulic press loading bridge is a specialized auxiliary equipment that maintains rapid loading and unloading of goods. Its height adjustment function creates a bridge between the large truck and the cargo platform in the warehouse. Transport vehicles such as electric forklifts can immediately enter the large truck to carry out mass loading and unloading of goods， also known as the loading and unloading service platform. That way， the device can loosen the return valve button during the lowering process， thereby reducing the weight of the device.
Insufficient understanding of the operating conditions of the axle. Assuming you understand some fundamental principles and the three elements that lead to success， you can ensure that you are in excellent working form for a long time. Inspection before use of mobile boarding bridge: Check if the oil unloading valve is tightened. Use of mobile boarding bridge: Use a hand pump to raise the boarding bridge to the required position and height; Place the tongue plate on the box and connect the safety chain to the box; Place the wheel mask in a suitable position next to the tire; Release the manual oil unloading valve to make the oil cylinder and wheels in a natural state， loading and unloading can begin; Precautions for operation: Keep the oil cylinder in a relaxed state during use; Both electric and manual lifting must turn off the manual pump switch.
whereThe guide sleeve has air holes， sand holes， shrinkage， and other conditions. Generally， there is a problem with the casting， which is the quality of the oil cylinder itself. At this time， it is necessary to find a manufacturer to replace the new boarding bridge. Normally， this situation does not occur in the casting oil cylinder. The above two reasons are due to the occurrence of excessive oil leakage， and frequent inspections should be conducted in these two areas. Hydraulic loading and unloading bridge is a specialized auxiliary equipment that maintains rapid loading and unloading of goods during the application process. The height adjustment function of the equipment makes the bridge in the middle of the truck guide sufficient to be built. Lifting platforms， trucks， and hydraulic loading and unloading bridges are commonly used cargo loading and unloading equipment.
Function: Convenient unloading， strong stability， and low maintenance cost. Suitable for various vehicles on loading and unloading sites and places with relatively busy traffic. Loading and unloading platforms， lifting platforms， and unloading platforms: anti slip device: This device is welded from steel plates， which can effectively achieve anti slip function and is safe and reliable.
. Platform side boarding bridge: The platform side boarding bridge is directly installed at the front edge of the loading and unloading platform. There is no need to excavate or reserve pits on the loading and unloading operation platform， and there is basically no change to the building structure. During construction， the factors of loading and unloading operations were not taken into account. The platform type loading and unloading bridge serves as a remedial solution and can also meet the requirements for loading and unloading operations into truck carriages.

Point. The DCQY type is a hand operated variable amplitude type， operated by a hand pump， which can achieve variable amplitude on the bridge board without the need for power supply; Widely used in mobile loading and unloading places without loading and unloading equipment and loading and unloading platforms; It is a safe， reliable， time-saving， land-saving logistics machinery that solves high-altitude differential operations.
At the beginning， it is essential to inspect and maintain the fixed hydraulic boarding bridge before or after use， and pay attention to whether it can be used correctly
