MontpellierAutReasons 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.
The hydraulic lifting boarding bridge is a specialized auxiliary equipment for fast loading and unloading of goods. Its height adjustment function allows a bridge to be built between the truck and the cargo platform in the warehouse. Forklifts and other handling vehicles can directly enter the truck for batch loading and unloading of goods, and single person operations can achieve fast loading and unloading of goods. Reduce a large amount of labor, improve work efficiency, and achieve greater economic benefits for enterprises.
Montpellier.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.
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.
.As an important part of the boarding bridge, the height can be adjusted according to the different vehicles of the goods, so that it can be level with the platform of the carriage for batch loading and unloading of goods. Due to the production of electric hydraulic boarding bridges by different manufacturers, the height of the design and manufacturing platform and the distance from the ground also vary, and the height of the electric hydraulic boarding bridge itself plus the stroke height is 1800mm, which can be met by almost all freight vehicles (with a general vehicle height of 1600).
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.
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 7000mm to 7500mm, 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 20% higher than the market value! More than one ton is more expensive!
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.
Advantages: Widely used high-altitude work equipment, stable and safe, with a wide range of operations.
As an important part of the boarding bridge, the height can be adjusted according to the different vehicles of the goods, so that it can be level with the platform of the carriage for batch loading and unloading of goods. Due to the production of electric hydraulic boarding bridges by different manufacturers, the height of the design and manufacturing platform and the distance from the ground also vary, with heights ranging from 1000mm to 1200mm. The hydraulic lifting stroke height ranges from 300mm to 600mm, which can be met by almost all freight vehicles (with a general vehicle height of 1600).
Quality assurance.Monthly maintenance of hydraulic boarding bridges: check for wear on rollers intermediate shafts and bearings, cylinder pins and bearings, boom hinge shafts and bearings,MontpellierFixed hydraulic boarding bridge, 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.
When confirming that the lip is fixed to the container, pull out the hook to hook it into the container tighten the chain to ensure that it does not loosen, and press the brake blocks on both sides. The boarding bridge is already a very visible structural form in modern logistics sites. It is the point and endpoint of the enterprise logistics chain, and a loading and unloading operation platform for enterprises to quickly and safely turnover products and goods. The height of the loading and unloading operation platform is fixed, but there is always a certain height difference or gap between the transportation vehicles and the loading and unloading platform due to the height of the carriage. Causing the forklift to be unable to enter and exit the transportation vehicle for direct loading and unloading of goods. Use the boarding bridge to provide reliable connections. 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, and transportation are not fixed or moving; Mobile hydraulic press boarding bridge: suitable for fixed and immovable goods such as ports, cargo platforms, warehouses, etc
Connection for. Enable forklift trucks to safely and quickly enter and exit transportation vehicles for loading and unloading operations.
Quality improvement.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.
When the boarding axle is far away from the frame, the rod moves downward to open the air release valve, and the air in the air spring is atmospheric, and the body and frame then reduce to the original value. The dual or multi axle air suspension boarding axle can also be lifted on a single or multiple axle when unloaded or partially loaded, which can protect the raised tires. Simultaneously reducing incorrect guidance while reducing tire wear on other axles. In addition, there are other positive effects during the driving process. On the one hand, it generates appropriate stable force when unloaded and partially loaded, it improves the adhesion of the drive shaft.
The user department of the hydraulic boarding bridge should scientifically analyze the equipment and reasonably determine the investment in the equipment. At the same time according to the characteristics of the work, professional personnel should be arranged to carry out on-site maintenance and upkeep to ensure that the lifting platform truck is always in normal operation, ensuring timely loading and unloading of supplied materials; The normal operation of equipment needs to be guaranteed by institutional measures, improve relevant management systems, strengthen dynamic management of equipment faults, and analyze the patterns of faults through maintenance; It is necessary to ensure the supply of maintenance accessories, establish a spare parts warehouse for vulnerable and commonly used parts, and purchase channels to avoid situations where inadequate preparation may lead to extended downtime and increased repair costs; Users should maintain a close relationship with survival manufacturers, so that they can handle faults in a short period of time.
Montpellier.The platform side boarding bridge is directly installed at the front edge of the loading and unloading platform. There is no need to excavate or reserve pits on the loading and unloading operation platform, and there is basically no change to the building structure.
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?
1. Before use, check the boarding bridge for obvious damage such as cracks and broken wires.
