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 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. After hearing the noise from the hydraulic boarding bridge, 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.
Connection for. Enable forklift trucks to safely and quickly enter and exit transportation vehicles for loading and unloading operations.
Italy.The boarding bridge can be divided into two forms: a mobile boarding bridge and a fixed boarding bridge. A brief introduction to the application scope of a fixed boarding bridge and the use of a mobile boarding bridge: used for on-site vehicles without loading and unloading platforms or places that require mobile loading and unloading of goods. If there is no loading and unloading platform vehicle at the logistics site, as a remedial measure, the mobile boarding bridge is incorrect
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!
.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, so it is not a major problem.
It is strictly prohibited to apply excessive pile loads around the foundation pit.
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.
Monthly maintenance of hydraulic boarding bridges: check for wear on rollers, 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.
Maintain the hydraulic system of the hydraulic boarding bridge. Keep the hydraulic oil of the hydraulic boarding bridge clean: Store the oil in a clean location, and be careful when changing or refueling. Only use a cleaning funnel equipped with a fine mesh filter to pour oil from the container into the oil tank. Of course, the oil you use should be the type recommended by the equipment manufacturer.
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.
Quality inspection report.conduct.
Open the manual valve, slowly lower the boarding bridge, and secure more than 90% of the lip plates at the bottom of the container.
During use, and if there are any problems, the use should be stopped immediately.
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,ItalyHydraulic fixed boarding bridge, 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.
demand.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,ItalyMobile hydraulic boarding bridge, 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.

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, motor rotates but lifting platform does not rise, lowering valve is open, overflow valve pressure is low, oil pump is empty, oil suction filter is blocked, 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.
Italy.The electronic operation is very simple. With just one button, the air conditioning panel will automatically rise. Release the button, adjust the plate to reduce itself, and the hinge is used on the truck.
Portable hydraulic press boarding bridge: It is a widely used type, suitable for places where loading, unloading, and transportation are not fixed or moving; Mobile hydraulic press boarding bridge: suitable for fixed and immovable goods such as ports, cargo platforms, warehouses, etc
1. Before use, check the boarding bridge for obvious damage such as cracks and broken wires.
