WroclawMovablethe relief valve gets stuck or severely worn
The safety valve of the mobile hydraulic boarding bridge can also generate high noise. When air is mixed into hydraulic oil, 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.
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,WroclawMobile Yard Ramps , support first and then excavation, layered excavation, no overbreak&rquote; The principle of.
Wroclaw.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, 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,WroclawMobile cllimbing, as overloading may cause damage to objects; Working on a lifting platform without protective barriers may cause personnel to fall and cause casualties.
.The precautions during the use of hydraulic boarding bridges are hoped to be helpful to you.
When it comes to fixed hydraulic boarding bridges I believe
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, 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.
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,WroclawEmbedded boarding bridge, 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.
When the boarding axle is far away from the frame, the rod moves downward to open the air release valve, and the air in the air spring is atmospheric, and the body and frame then reduce to the original value. The dual or multi axle air suspension boarding axle can also be lifted on a single or multiple axle when unloaded or partially loaded, which can protect the raised tires. Simultaneously reducing incorrect guidance while reducing tire wear on other axles. In addition, there are other positive effects during the driving process. On the one hand, it generates appropriate stable force when unloaded and partially loaded, and on the other hand, it improves the adhesion of the drive shaft.
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.
Industry management.During construction, the factors of loading and unloading operations were not taken into account. The platform type loading and unloading bridge serves as a remedial solution and can also meet the requirements for loading and unloading operations into truck carriages. The platform type boarding bridge is also designed in various structural forms according to different on-site conditions. It can also be adjusted up (below the cargo platform) or down (below the cargo platform) within a certain range which can meet the installation and use of most loading and unloading platforms. Is the boarding bridge easy to use? The boarding bridge is an auxiliary equipment used to bridge with the freight car and is designed to solve the height difference between the freight car and the ground. Suitable for fixed or mobile loading and unloading of goods, it is actually equivalent to a slope, allowing forklifts to smoothly enter the carriage to load and unload goods, requiring only one person to quickly load and unload goods, which is labor-saving.
Nowadays, the electric hydraulic boarding bridge has become a loading and unloading tool used by many companies. Compared to many friends, I am still not very familiar with electric hydraulic boarding bridges. Below, the editor will explain the product parameters and specifications related to the length, slope, and height of the electric hydraulic boarding bridge.
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.
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
Scheme customization.When working in foundation pits or depths, a helmet must be worn.
When working at heights exceeding 1.5 meters, safety nets or safety belts must be used.
When it comes to fixed hydraulic boarding bridges, I believe
Wroclaw.Common&quo; Work” Steel structure planning can withstand uniform pressure, reduce skeleton torque, and be more robust than other channel structures.
The reason for the natural descent of the hydraulic boarding bridge lifting platform is that the one-way valve is leaking, clean the one-way valve. Check if the lowering valve has power. If there is power 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.
What are the issues to pay attention to when using the boarding bridge? For example, mobile boarding bridges are generally used outdoors, they are also placed outdoors. They are often exposed to wind, rain, and sunlight, which reduces the lifespan of the boarding bridge. Therefore, the maintenance of the boarding bridge is very important. When it rains, cover the boarding bridge with a rain cloth to prevent rusting and aging.
