LeshnoBoardingPortable hydraulic press boarding bridge: It is a widely used type, suitable for places where loading, unloading, and transportation are not fixed or moving; Mobile hydraulic press boarding bridge: suitable for fixed and immovable goods such as ports, cargo platforms warehouses, etc
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.
Leshno.High altitude work platform vehicles are mainly divided into four types: scissor type, straight arm type, curved arm type, and vehicular type. Scissor fork type high altitude work platform vehicles.
Open the manual valve, slowly lower the boarding bridge, and secure more than 90% of the lip plates at the bottom of the container.
.There is a lot of noise generated when using a mobile hydraulic boarding bridge. So, steel cylinders pump stations, and steel equipment are all sources of noise. Today we will analyze for you: 1. 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 electronic operation is very simple. With just one button, the air conditioning panel will automatically rise. Release the button, adjust the plate to reduce itself, and the hinge is used on the truck.
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, 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, no overbreak&rquote; The principle of.
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,LeshnoProcurement of fixed boarding bridges, we should regularly clean the safety valve, and replace it if it is damaged or severely worn.
Mobile boarding bridge is a cargo loading and unloading auxiliary equipment used in conjunction with forklifts, which can adjust the height according to the height of the car carriage. Forklifts can directly enter the interior of the carriage for batch loading and unloading of goods,LeshnoMobile hydraulic boarding bridge, and can achieve rapid loading and unloading of goods with only one person working. It enables enterprises to reduce a large amount of labor, improve work efficiency, and obtain greater economic benefits.
The width of the boarding bridge also requires a certain width of its own. However, 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,LeshnoBoarding axle manufacturer, 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, 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.
What is a hydraulic boarding axle? The hydraulic boarding bridge is a special auxiliary equipment used for fast loading and unloading of goods, and its height adjustment function can build a bridge between the truck and the warehouse platform. What are the operational steps we take during use?
Check if the manual valve is open. When using, it must be opened, otherwise the boarding bridge may be damaged.
device management.conduct.
Keep the work area clean: A) When refueling or refilling the fuel tank, 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.
Hydraulic 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.
Leshno.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.
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.
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.
