Gu YeTelescopiCheck if the manual valve is open. When using, it must be opened,Gu YeFixed hydraulic boarding bridge, otherwise the boarding bridge may be damaged.
To ensure that the hydraulic boarding bridge is in good condition, mainly including whether the buttons are effective; Whether the power cord and socket are intact; Whether the oil pipeline is intact; The stability of the guardrail; The tightness of bolts at each junction point; The appearance quality is intact. But when the power is turned on and the indicator light is on, press the up button, the motor rotates but the lifting table does not rise. This may be due to the reverse connection of the three-phase power supply and the motor reversing. Only the power supply needs to be corrected, so it is not a major problem.
Gu Ye.Introduction to Fixed Boarding Bridge Loading and unloading Mobile Boarding Bridge is a very common structural form in modern logistics sites. It is the point and endpoint of the enterprise's logistics chain, and is a loading and unloading platform vehicle for enterprises to quickly and turnover products and goods. The height of the loading and unloading operation platform truck is fixed, but the height of the transport carriages does not always form a certain height difference or gap between the transport vehicle and the loading and unloading platform. 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 quickly enter and exit transportation vehicles for loading and unloading operations.
It is strictly prohibited to apply excessive pile loads around the foundation pit.
. 1. Before use, check the boarding bridge for obvious damage such as cracks and broken wires.
There is a flip plate at the top of the bridge deck, 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.
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.
Advantages: The operation results are simpler, the operation is convenient, the stability is good, the safety is reliable and has advantages. It is a common equipment for high-altitude operations.
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.
Word of mouth recommendation.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.
Shake the handle to raise the boarding bridge to the height of the container.
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?
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.
demand.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.
Keep the work area clean: A) When refueling or refilling the fuel tank,Gu YeHydraulic fixed boarding axle, ensure that the area around the filter box cover is clean. Only clean oil and funnels or containers can be used. Do not bring dirt into the system– It can only be clean oil.
The hydraulic boarding bridge is a specialized auxiliary equipment for achieving rapid loading and unloading of goods, and is our good helper. However, malfunctions during use are inevitable. What should we do when encountering a malfunction?
Gu Ye.Portable hydraulic press boarding bridge: It is a widely used type, suitable for places where loading, and transportation are not fixed or moving; Mobile hydraulic press boarding bridge: suitable for fixed and immovable goods such as ports, cargo platforms,Gu YeAutomobile type boarding bridge, warehouses, etc
Reasons for the hydraulic boarding bridge lifting platform not lifting: low voltage, 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 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.
