NIMVehicle boaOperation degree: There are two types of operations that can be used to raise and lower the boarding bridge. One is a manual pump station, which uses manual hydraulic lifting, which is labor-intensive and somewhat labor-intensive. Advantages: It can be operated and used in any situation. Two types of electric pump stations use electric hydraulic lifting and lowering, which reduces labor intensity and saves labor. Disadvantage: Once the power is cut off, it will not be able to be used, but now there are both manual and electric boarding bridges that are more convenient to use.
The pressure on the axle will reduce the service life of the boarding axle.
NIM.(5) Each mechanism in the elevator should be checked for normal operation and any noise or other malfunctions. If any, they should be promptly addressed and resolved. All wires and cables in the mobile boarding bridge should be checked for any damage or damage, and if any, they should be promptly wrapped or replaced with new ones.
The precautions during the use of hydraulic boarding bridges are hoped to be helpful to 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.
There are three movable boards on both sides of the air conditioning board, which can effectively prevent the adjustment board from falling down and keep the pressure foot in a safe state.
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, 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, 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.
Tighten the manual valve to close it.
In the economic field, the safety, punctuality, flexibility, and price to efficiency ratio of transportation are directly related to the fate and survival of enterprises due to different road conditions. Therefore, especially those that serve as the main components of trailers and semi trailers. Continuously developing, 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.
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.
Affordable price.The width of the boarding bridge also requires a certain width of its own. However, if the width is too small, it is not conducive to forklift loading and unloading of goods. If the width is too large, it can occupy a certain space which is not necessary. So a reasonable width is necessary, usually the width of the electric hydraulic boarding bridge is 1800mm, 2000mm, and 2100mm. The width of the bridge is divided into internal width and total width. As we have already mentioned, the internal width is the width of the passage, and the total width mainly refers to the width of the guardrails on both sides plus the width of the passage. The total width can be ignored in use, but everyone still cares about the internal width, which is the width of the channel.
conduct.
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.
When working on the hydraulic boarding bridge, the support legs must be extended, and the support leg bolts must be adjusted to ensure that the lifting platform is stably stressed on the support legs and kept horizontal; During the lifting process and in the lifting state, the lifting platform must not be moved, and it is strictly prohibited to shake on the lifting platform. If there is an abnormal sound during the operation of the hydraulic boarding bridge, it should be stopped immediately for inspection to avoid causing serious damage to the lifting platform; Before use, check whether the electrical equipment is normal; All shaft pin oil holes must be oiled before each use. Before use, it is necessary to perform no-load lifting and check whether the hydraulic system is normal; The load of the workbench should not exceed the rated value, and it should not be subjected to intense manual shaking; The hydraulic oil in the oil tank must be replaced every 500 hours of operation.
Encyclopedic knowledge.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.
Features: Shear mechanical structure, working height generally ranging from 6 meters to 14 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, and internal combustion power supply). The manual hydraulic device can lift and retract normally in places with power outage or no power supply,NIMContainer boarding bridge, increase the telescopic platform car and extend to necessary positions in case of insufficient length of the platform car, improving work efficiency.
Connection for. Enable forklift trucks to safely and quickly enter and exit transportation vehicles for loading and unloading operations.
NIM.Shake the handle to raise the boarding bridge to the height of the container.
The hydraulic system adopts imported Italian brand products, with excellent performance and minimal maintenance. The oil cylinder lifting power system,NIMThe boarding bridge, inclined plate, top,NIMMaintenance of 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!
