OpalEmbedded bReason 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.
conduct.
Opal.High altitude work requires the use of tool bags, and heavier and larger high-altitude work tools should be hung on stable components and cannot be placed randomly to avoid the occurrence of high-altitude falling accidents.
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.
.Check if the manual valve is open. When using, it must be opened, otherwise the boarding bridge may be damaged.
Install a 5m high protective railing around the foundation pit of the simple boarding bridge,OpalPlatform boarding bridge, without the need for power supply, support first and then excavation, layered excavation, no overbreak&rquote; The principle of.
These are the options for hydraulic oil for mobile boarding bridges.
The correct operation of the hydraulic boarding bridge is good maintenance, and how to operate it correctly. Let me briefly introduce the operating steps of the hydraulic boarding bridge, hoping to bring more help to everyone.
The emergence of mobile boarding bridges solves the problem of cargo loading and unloading auxiliary boarding equipment for forklifts entering the ground of freight containers and the height difference between trucks. The mobile boarding bridge can adjust the height of the mobile boarding bridge to be level with the height of the container according to the height of the truck container, achieving rapid loading and unloading of goods and improving the efficiency of cargo loading and unloading. So, what are the abnormalities that can be observed during the use of the mobile boarding bridge?
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,OpalDesign of mobile boarding bridge, construction must be suspended and reported to the superior for handling.
equipment maintenance .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.
After the boarding bridge work is completed, all parts should be scrubbed and cleaned. When not working, the workbench should be lowered to a low position.
During use, close attention should be paid to the condition of the equipment, and if there are any problems, the use should be stopped immediately.
Is the boarding bridge easy to use? Those who have used the boarding bridge know that it is a very useful mechanical equipment, which brings great convenience to the logistics industry and some industrial factories that need to load and unload goods. Some enterprises also value the development prospects of the boarding bridge and set up factory boarding bridges. High priced and various specifications of boarding bridge manufacturers provide timely supply, with high cost-effectiveness, and has become the preferred brand for many wire products. Welcome to choose!
Promise and keep promise.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,OpalThe boarding bridge is movable, no overbreak&rquote; The principle of.
Applicable scenario: Suitable for mobile high-altitude operations such as setting and inspection of high-altitude equipment in various industries.
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.
Opal.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.
Monthly maintenance of hydraulic boarding bridges: check for wear on rollers, intermediate shafts and bearings, cylinder pins and bearings, boom hinge shafts and bearings, 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, motor not rotating making the boarding bridge better serve you.
