BenjinFixed hyWhen the hydraulic oil is insufficient, causing air to enter the hydraulic oil and also producing high noise. 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.
Connection for. Enable forklift trucks to safely and quickly enter and exit transportation vehicles for loading and unloading operations.
Benjin.Keep the hydraulic boarding bridge system clean: regularly replace the oil and filter. Good hydraulic oil contains various additives that can prevent oil deterioration or blockage of system components. However, these additives will lose their effectiveness after a period of time. Therefore, the oil should be replaced regularly to ensure that the additives are effective. The filter can only absorb a limited number of dirt particles and other impurities from the oil. Replace the filter according to the recommended cycle to keep the system clean.
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.
.After the boarding bridge work is completed, all parts should be scrubbed and cleaned. When not working, the workbench should be lowered to a low position.
The pressure on the axle will reduce the service life of the boarding axle.
When working in foundation pits or depths a helmet must be worn.
Portable hydraulic press boarding bridge: It is a widely used type, 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
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.
During use, close attention should be paid to the condition of the equipment, and if there are any problems, the use should be stopped immediately.
Statistics.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, press the up button, motor rotates but lifting platform does not rise, 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,BenjinMaintenance of 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 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 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,BenjinRetractable boarding bridge, hoping to bring more help to everyone.
The precautions during the use of hydraulic boarding bridges are hoped to be helpful to you.
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.
Inspection requirements.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.
The mobile boarding bridge suddenly loses control of the operating platform.
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, 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.
Open planning before placement makes it easy to clean up clutter.
These are the options for hydraulic oil for mobile boarding bridges.
