MacaoDengCheQiHydraulic 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.
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 inquire
Macao.When conducting high-altitude operations on dangerous edges such as roofs, suspension bridges, slopes or cliffs, guardrails or safety nets should be installed on the side facing the air, or safety belts or ropes should be used.
Hydraulic boarding bridges should strictly adhere to the principle of being overweight, 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.
Connection for. Enable forklift trucks to safely and quickly enter and exit transportation vehicles for loading and unloading operations.
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,MacaoContainer boarding bridge,MacaoAutomatic boarding bridge, 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.
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,MacaoMaintenance of boarding bridge, but everyone still cares about the internal width, which is the width of the channel.
Regularly draining and refilling the oil tank to remove water and sediment is crucial for removing impurities in the oil but regularly emptying the entire hydraulic system is also crucial. This is a reliable way to completely remove system impurities, oxidized hydraulic oil, and other harmful substances. Then, the recommended clean hydraulic oil should be added back to the system. If the oil is completely contaminated, especially when the pump is damaged, the oil in the tank must be cleaned. The oil cleaning device allows the oil to flow until the oil pollution indicator shows that the oil is in a satisfactory 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, 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.
recommend.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.
conduct.
Operation 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 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, 11200m for 8 tons and the bearing weight varies depending on the tonnage. It is 10500mm for 6 tons, and 11300m for 10 tons. It is very suitable for placement on the ground in open spaces.
market.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.
There are the following: (1) The brake of the elevator should be regularly inspected to see if its clearance is appropriate, as well as some other aspects, in order to ensure its flexibility and reliability in use. In addition, on the friction surface of the brake, it is necessary to check for any dirt, and if any, it should be cleaned in a timely manner. (2) For the part of the moving boarding bridge, it should be carried out in accordance with the specified requirements, and it should be comprehensive and sufficient without any omissions. However, the amount of oil should not be too much, as too much can also cause problems.
To ensure that the hydraulic boarding bridge is in good condition, it should be checked in advance before use, 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.
Macao.Operation 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.
Install drainage ditches on the ground near the pit of the simple boarding bridge, and take corresponding drainage measures for the top, surface, and foot of the slope, especially for the simple boarding bridge.
During excavation, if unidentifiable items or unforeseeable situations are found, the operation should be stopped in a timely manner and reported to the person in charge of the hydraulic boarding bridge for handling. The fixed boarding bridge is an auxiliary equipment for loading and unloading in conjunction with the storage platform. This equipment is integrated with the platform and can be adjusted up or down according to the different heights of the truck carriage, making it convenient for forklifts to enter the carriage. The equipment adopts an imported hydraulic pump station with anti rolling skirts on both sides, making work safer and improving work efficiency.
