ClichyFixed hydraulic boarding axleWill there be any improvement in the trend of joint production reduction by manufacturers

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.

After the boarding bridge work is completed, all parts should be scrubbed and cleaned. When not working,ClichyFixed boarding bridge, the workbench should be lowered to a low position.

Clichy.Regularly draining and refilling the oil tank to remove water and sediment is crucial for removing impurities in the oil, but regularly emptying the entire hydraulic system is also crucial. This is a reliable way to completely remove system impurities, oxidized hydraulic oil,ClichyMovable boarding bridge, and other harmful substances. Then, the recommended clean hydraulic oil should be added back to the system. If the oil is completely contaminated, the oil in the tank must be cleaned. The oil cleaning device allows the oil to flow until the oil pollution indicator shows that the oil is in a satisfactory state.

.Open planning before placement makes it easy to clean up clutter.

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.

During the excavation process of the foundation pit of the simple boarding bridge, collision of the support structure should be prevented, and changes in the soil wall should be paid attention to at all times. If any abnormal phenomena such as cracks are found, construction must be suspended and reported to the superior for handling.

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.

High altitude work requires the use of tool bags, and heavier and larger high-altitude work tools should be hung on stable components and cannot be placed randomly to avoid the occurrence of high-altitude falling accidents.

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.

OK or not?.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.

Do you know some of the working characteristics of hydraulic lifting boarding bridges? Today, I will take you to understand!

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, making the boarding bridge better serve you.

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, 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.

Trustworthy.Tighten the manual valve to close it.

Remove and disassemble the lowering valve, blow the valve core clean with compressed air,ClichyHydraulic mobile boarding bridge, and then reinstall it.

It is strictly prohibited to apply excessive pile loads around the foundation pit.

Clichy.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, which is not necessary. So a reasonable width is necessary it can occupy a certain space, 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, which is the width of the channel.

The reason for the natural descent of the hydraulic boarding bridge lifting platform is that the one-way valve is leaking, 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.
