MainzAluminum alloy boarding bridgeWhat tests should be done before use

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.Mainz,Staying below high-altitude work sites is prohibited, and safety nets or other protective devices should be installed below the work site to avoid injury from falling objects.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,MainzMobile lifting boarding bridge, we should regularly clean the safety valve, and replace it if it is damaged or severely worn.Nueva Helvecia,The pressure on the axle will reduce the service life of the boarding axle.When replacing hydraulic oil, as well as noise when the pump station enters the air.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.

Open the manual valve, slowly lower the boarding bridge, and secure more than % of the lip plates at the bottom of the container.Features: Shear mechanical structure,MainzDesign of boarding bridge, working height generally ranging from meters to meters, high stability after lifting the platform, wide working platform vehicle and high load capacity, single-phase AC power supply suitable for multiple people working simultaneously. The power form can be selected according to different requirements (such as three-phase AC power supply, DC power supply, and internal combustion power supply). The manual hydraulic device can lift and retract normally in places with power outage or no power supply, increase the telescopic platform car, and extend to necessary positions in case of insufficient length of the platform car, improving work efficiency.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.technical service,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 mm to mm, 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 % higher than the market value! More than one ton is more expensive!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.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 pump is empty, oil suction filter is blocked, oil suction section is leaking, 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 % 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.

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.Interpretation and observation,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.C) When maintaining hydraulic components,MainzHydraulic boarding bridge, the workbench must be absolutely clean. Check the condition of the tools used. They should also be very clean.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.Mainz,When 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.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.Shake the handle to raise the boarding bridge to the height of the container.
