WolfsburgMovabWhen replacing hydraulic oil, sometimes poor hydraulic oil can also cause noise on the hydraulic boarding bridge, as well as noise when the pump station enters the air.
Do you know some of the working characteristics of hydraulic lifting boarding bridges? Today, I will take you to understand!
Wolfsburg.Drain all the hydraulic oil in the oil tank, open the oil tank, take out the oil suction filter, clean it, and return it to the oil tank. Install it in its original position. Fill the fuel tank with new oil.
Check if the manual valve is open. When using, it must be opened, otherwise the boarding bridge may be damaged.
.The reason for the natural descent of the hydraulic boarding bridge lifting platform is that the one-way valve is leaking, 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 pressure on the axle will reduce the service life of the boarding axle.
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.
conduct.
Features: Adopting a foldable arm (two section arm, three section arm), with a working height of 15-45 meters, and the lifting arm can rotate 360 degrees;, Both the turntable and the work platform can be operated. The work platform can safely walk with the boom in any position, and the walking speed decreases with the rise of the lifting height. Set up the upper and lower platforms (ground platform and platform vehicle platform), and use directional switches to switch between the upper and lower platforms.

Industry management.What is a hydraulic boarding axle? The hydraulic boarding bridge is a special auxiliary equipment used for fast loading and unloading of goods and its height adjustment function can build a bridge between the truck and the warehouse platform. What are the operational steps we take during use?

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,WolfsburgMobile boarding axle hydraulic pressure, 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.
Is the boarding bridge easy to use? Those who have used the boarding bridge know that it is a very useful mechanical equipment, with high cost-effectiveness, and has become the preferred brand for many wire products. Welcome to choose!
Welcome calls .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, they should be promptly addressed and resolved. All wires and cables in the mobile boarding bridge should be checked for any damage or damage, and if any, 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, 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.
Wolfsburg.Monthly maintenance of hydraulic boarding bridges: check for wear on rollers, intermediate shafts and bearings, cylinder pins and bearings, boom hinge shafts and bearings,WolfsburgAutomobile boarding bridge manufacturer, 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.
