The reason for the natural descent of the hydraulic boarding bridge lifting platform is that the one-way valve is leaking, the lowering valve is not tightly sealed, and the oil cylinder is leaking. Solution: Check the one-way valve in the valve group. If dirt is found on the sealing surface of a single valve, troubleshoot the lowering valve itself or replace the lowering valve. The slide valve of the lowering valve must be kept clean and move flexibly.It is strictly prohibited to apply excessive pile loads around the foundation pit.Zhongshan,Features: Shear mechanical structure, working height generally ranging from meters to meters, high stability after lifting the platform, wide working platform vehicle and high load capacity, wide range of high-altitude work, suitable for multiple people working simultaneously. The power form can be selected according to different requirements (such as three-phase AC power supply, single-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.Tighten the manual valve to close it.Ciudad-Victoria,When it comes to fixed hydraulic boarding bridges, intermediate shafts and bearings, cylinder pins 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 to 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.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, 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.

The reason for the natural descent of the hydraulic boarding bridge lifting platform is that the one-way valve is leaking, the lowering valve is not tightly sealed, and the oil cylinder is leaking. Solution: Check the one-way valve in the valve group. If dirt is found on the sealing surface of a single valve, clean the one-way valve. Check if the lowering valve has power. If there is power troubleshoot the lowering valve itself or replace the lowering valve. The slide valve of the lowering valve must be kept clean and move flexibly.In the economic field, the safety, punctuality, and price to efficiency ratio of transportation are directly related to the fate and survival of enterprises due to different road conditions. Therefore,ZhongshanHydraulic mobile boarding bridge, people have high expectations for commercial freight hydraulic boarding bridges, especially those that serve as the main components of trailers and semi trailers. Continuously developing, developing,ZhongshanFolding boarding bridge, and producing multiple series and varieties of hydraulic boarding bridges to meet the needs of modern cargo transportation. Below is an introduction to the characteristics of the hydraulic boarding bridge suspension system.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.Administration,Common&quo; Work” Steel structure planning can withstand uniform pressure, reduce skeleton torque, and be more robust than other channel structures.Embedded boarding bridge, as the name suggests, refers to the boarding bridge embedded in the loading and unloading operation platform. The installed boarding bridge main board surface is horizontal with the upper plane of the loading and unloading operation platform. Completely integrated into the platform, it will not affect other operational tasks on the platform without loading and unloading operations. The boarding bridge with this type of structure is widely used and is also a relatively fast boarding auxiliary device. Its design is usually fully standardized as early as the structural design of buildings. We are a long-term manufacturer of boarding bridges. Welcome to inquireThere is a lot of noise generated when using a mobile hydraulic boarding bridge. So, where are these noises caused? In fact, pump stations, steel cylinders,ZhongshanMoving the boarding bridge, and steel equipment are all sources of noise. Today we will analyze for you: . 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. After hearing the noise from the hydraulic boarding bridge, first check if there are any problems with the hydraulic pump station, motor, valve, and fixing device, and if the noise is caused by its vibration.

The precautions during the use of hydraulic boarding bridges are hoped to be helpful to you.For more, please check,Open planning before placement makes it easy to clean up clutter.Usage environment: Able to adapt to specific working environments, such as working in highly corrosive dusty, high-temperature, and low-temperature environments.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 % 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.Zhongshan,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.These are the options for hydraulic oil for mobile boarding bridges.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.
