HardenbachLiftWhat are the issues to pay attention to when using the boarding bridge? For example, mobile boarding bridges are generally used outdoors, and after use, rain, and sunlight, which reduces the lifespan of the boarding bridge. Therefore, the maintenance of the boarding bridge is very important. When it rains, cover the boarding bridge with a rain cloth to prevent rusting and aging.
Check if the manual valve is open. When using, it must be opened, and their respective roles and application fields are also different. Hydraulic boarding bridges, fixed boarding bridges, and mobile boarding bridges are currently common and advantageous equipment on the market playing a huge role in their respective fields. Below, we will first analyze the development trend of mobile boarding bridges: mobile hydraulic boarding bridges are a good helper for loading and unloading goods on forklifts. Compared to pneumatic tires, mobile boarding bridges are equipped with solid tires with low starting resistance, simple structure, convenient use and maintenance, no need for inflation, no hidden dangers of air leakage and tire explosion. And solid tires have good safety, durability, puncture resistance, tear resistance, and economy.
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.
.Open planning before placement makes it easy to clean up clutter.
Reason for the lifting table not lowering: The lowering valve is malfunctioning, and the lowering speed valve is out of adjustment. Solution: When pressing the lowering button, check if the lowering valve is energized. If there is no electricity, try to eliminate it; If there is electricity, troubleshoot the lowering valve itself or replace the lowering valve. The lowering valve should be kept clean.
1. Before use,HardenbachHydraulic mobile boarding bridge, check the boarding bridge for obvious damage such as cracks and broken wires.
When working in foundation pits or depths, a helmet must be worn.
Remove and disassemble the lowering valve, blow the valve core clean with compressed air, and then reinstall it.
It is strictly prohibited to apply excessive pile loads around the foundation pit.
Quality management.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.
Check if the manual valve is open. When using, it must be opened, otherwise the boarding bridge may be damaged.
Connection for. Enable forklift trucks to safely and quickly enter and exit transportation vehicles for loading and unloading operations.
Portable hydraulic press boarding bridge: It is a widely used type, suitable for places where loading, unloading, cargo platforms, etc
Meticulous workmanship.During the excavation process of the foundation pit of the simple boarding bridge, collision of the support structure should be prevented,HardenbachDesign of mobile boarding bridge, 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.
Please check if the power supply is stable and if there is a disconnection in the circuit. If everything is checked to be normal, it should be considered whether there is built-in power
During the application process of hydraulic boarding bridges, it is necessary to follow the operating procedures to ensure the normal operation of the equipment. What precautions should we take when using hydraulic boarding bridges?
Hardenbach.Common&quo; Work” Steel structure planning can withstand uniform pressure, reduce skeleton torque, and be more robust than other channel structures.
Slowly reverse and park the container under the lip at the front of the boarding bridge.
