OsnablukEmbeddDo you know some of the working characteristics of hydraulic lifting boarding bridges? Today, I will take you to understand!
Check if the manual valve is open. When using, it must be opened, otherwise the boarding bridge may be damaged.
Osnabluk.When conducting high-altitude operations on dangerous edges such as roofs, suspension bridges, slopes,OsnablukHydraulic lifting boarding bridge, or cliffs, guardrails or safety nets should be installed on the side facing the air, or safety belts or ropes should be used.
Slowly reverse and park the container under the lip at the front of the boarding bridge.
.What are the issues to pay attention to when using the boarding bridge? For example, mobile boarding bridges are generally used outdoors, and after use, they are also placed outdoors. They are often exposed to wind, rain, and sunlight, which reduces the lifespan of the boarding bridge. Therefore, the maintenance of the boarding bridge is very important. When it rains, which can effectively prevent the adjustment board from falling down and keep the pressure foot in a safe state.
Check if the manual valve is open. When using it must be opened, otherwise the boarding bridge may be damaged.
Shake the handle to raise the boarding bridge to the height of the container.
When working at heights exceeding 1.5 meters, safety nets or safety belts must be used.
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.
Installation conditions.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.
Tighten the manual valve to close it.
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.
These are the options for hydraulic oil for mobile boarding bridges.
Finance Department.During the excavation process of the foundation pit of the simple boarding bridge, collision of the support structure should be prevented, construction must be suspended and reported to the superior for handling.
Check the hydraulic oil quality and level. When the lifting platform is raised to a high position, the oil becomes sticky, or there are foreign objects such as gravel in the oil, the hydraulic oil should be replaced in a timely manner. The hydraulic system of the lifting platform should be checked for hydraulic and pipeline connections. If the pipeline is damaged, it should be replaced immediately; When there is looseness in the connection part, tighten the pipe joint.
1. Before use, check the boarding bridge for obvious damage such as cracks and broken wires.
Osnabluk.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),OsnablukMobile lifting boarding bridge, 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,OsnablukHydraulic boarding bridge, 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.
Common&quo; Work” Steel structure planning can withstand uniform pressure, reduce skeleton torque, and be more robust than other channel structures.
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, hoping to bring more help to everyone.
