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?
Gujiao.Check the hydraulic oil quality and level. When the lifting platform is raised to a high position, the hydraulic oil level should be 40-50 millimeters higher than the bottom of the oil tank. When the color of the hydraulic oil darkens, or there are foreign objects such as gravel in the oil, the hydraulic oil should be replaced in a timely manner. The hydraulic system of the lifting platform should be checked for hydraulic and pipeline connections. If the pipeline is damaged, it should be replaced immediately; When there is looseness in the connection part, tighten the pipe joint.
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 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?
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 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.
When it comes to fixed hydraulic boarding bridges, I believe
For slopes that are unstable or unstable after earthwork excavation,GujiaoWarehouse boarding bridge, 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.
Check the hydraulic oil quality and level. When the lifting platform is raised to a high position, the hydraulic oil level should be 40-50 millimeters higher than the bottom of the oil tank. When the color of the hydraulic oil darkens, the oil becomes sticky, or there are foreign objects such as gravel in the oil, the hydraulic oil should be replaced in a timely manner. The hydraulic system of the lifting platform should be checked for hydraulic and pipeline connections. If the pipeline is damaged, it should be replaced immediately; When there is looseness in the connection part, tighten the pipe joint.
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 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).
Meticulous workmanship.Reasons for the hydraulic boarding bridge lifting platform not lifting: low voltage, motor not rotating motor reverse, indicator light on, press the up button, motor rotates but lifting platform does not rise,GujiaoMobile Yard Ramps , lowering valve is open, overflow valve pressure is low, 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, 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.
The width of the boarding bridge also requires a certain width of its own. However, if the width is too small, 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, the internal width is the width of the passage, 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.
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,GujiaoMoving the boarding bridge, and single person operations can achieve fast loading and unloading of goods. Reduce a large amount of labor, improve work efficiency, close attention should be paid to the condition of the equipment, and if there are any problems, the use should be stopped immediately.
The mobile boarding bridge is a type of forklift that directly loads and unloads goods from the ground to the truck
The correct operation of the hydraulic boarding bridge is good maintenance, and how to operate it correctly. Let me briefly introduce the operating steps of the hydraulic boarding bridge, hoping to bring more help to everyone.
Gujiao.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.
Check if the manual valve is open. When using, it must be opened, otherwise the boarding bridge may be damaged.
Slowly reverse and park the container under the lip at the front of the boarding bridge.
