MannheimAutomoWhen the hydraulic oil is insufficient, the hydraulic pump will produce suction phenomenon, causing air to enter the hydraulic oil and also producing high noise. 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.
The length of the electric hydraulic boarding bridge is generally about 10 meters, and the bearing weight varies depending on the tonnage. It is 10500mm for 6 tons, 11200m for 8 tons, and 11300m for 10 tons. It is very suitable for placement on the ground in open spaces.
Mannheim.Fixed loading and unloading bridge: The fixed loading and unloading bridge is a specialized auxiliary equipment for achieving rapid loading and unloading of goods. Its height adjustment function uses a bridge between the truck and the cargo platform in the warehouse, and forklifts and other vehicles can move and load goods in batches inside the truck. Only one person can work to achieve rapid loading and unloading of goods. It enables enterprises to reduce a large amount of labor, improve work efficiency and obtain greater economic benefits.
Do you know some of the working characteristics of hydraulic lifting boarding bridges? Today,MannheimLifting and lowering of boarding bridge, I will take you to understand!
.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.
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, oil level is too low, oil pump is empty, oil suction filter is blocked, oil suction section is leaking,MannheimHuangshi boarding bridge, 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.
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.
Check if the manual valve is open. When using, it must be opened, otherwise the boarding bridge may be damaged.
Advantages: Widely used high-altitude work equipment, stable and safe, with a wide range of operations.
Check if the manual valve is open. When using, it must be opened, otherwise the boarding bridge may be damaged.
quality standard.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!
Install a 5m high protective railing around the foundation pit of the simple boarding bridge, with a distance of no less than 1m from the protective railing to the foundation pit. The mobile boarding bridge only requires a single person to operate, without the need for power supply, and can achieve safe and fast loading and unloading of goods. Mobile boarding bridges are widely used in cargo platforms and mobile loading and unloading sites without loading and unloading equipment. They are auxiliary equipment for cargo loading and unloading that is used in conjunction with forklifts. The sequence of earthwork excavation must comply with design conditions and follow" Trenching support, support first and then excavation, layered excavation, no overbreak&rquote; The principle of.
During the excavation process of the foundation pit of the simple 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.
Hydraulic boarding bridges should strictly adhere to the principle of being overweight as overloading may cause damage to objects; Working on a lifting platform without protective barriers may cause personnel to fall and cause casualties.
Supply chain quality management.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, 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, and replace it if it is damaged or severely worn.
Mannheim.The hydraulic system adopts imported Italian brand products, with excellent performance and minimal maintenance. The oil cylinder lifting power system, inclined plate, top,MannheimHydraulic lifting boarding bridge, and small oil cylinder operation, can be adjusted smoothly. The height adjustment plate is a selected decorative plate and profile, with a long service life. Various qualified manufacturers of boarding bridges are welcome to inquire by phone and sincerely invite cooperation!
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, 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.
For slopes that are unstable or unstable after earthwork excavation, top-down segmented trench jumping should be adopted based on the geological characteristics and possible situations of the slope, and reverse construction or partial reverse construction should be carried out in a timely manner. It is strictly prohibited to excavate and explode indiscriminately.
