Portable 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
During use， close attention should be paid to the condition of the equipment， the use should be stopped immediately.
Colorado SpringsDrain all the hydraulic oil in the oil tank， open the oil tank， take out the oil suction filter， clean it， and return it to the oil tank. Install it in its original position. Fill the fuel tank with new oil.
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，Colorado SpringsLifting and lowering of boarding bridge， oil level is too low， 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 % 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.

As we all know
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.
Monthly maintenance of hydraulic boarding bridges: check for wear on rollers， intermediate shafts and bearings， cylinder pins and bearings， boom hinge shafts and bearings， the hydraulic surface should be to millimeters higher than the bottom of the box. The hydraulic oil is darkened and at this position 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.
Usage scenario: Widely applicable for installation， maintenance， and high-altitude work platform vehicles in industries such as municipal administration， electricity， streetlights， advertising， communication， photography， landscaping transportation， docks， airports and ports， and large industrial and mining enterprises.
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，Colorado SpringsRetractable boarding bridge， and there is basically no change to the building structure.
Latest quotationOperation 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， according to the characteristics of the work， professional personnel should be arranged to carry out on-site maintenance and upkeep to ensure that the lifting platform truck is always in normal operation， ensuring timely loading and unloading of supplied materials; The normal operation of equipment needs to be guaranteed by institutional measures， improve relevant management systems， strengthen dynamic management of equipment faults， monitor the status of key parts， and analyze the patterns of faults through maintenance; It is necessary to ensure the supply of maintenance accessories， establish a spare parts warehouse for vulnerable and commonly used parts， and purchase channels to avoid situations where inadequate preparation may lead to extended downtime and increased repair costs; Users should maintain a close relationship with survival manufacturers， strengthen the professional quality and professionalism of lifting platform maintenance personnel， so that they can handle faults in a short period of time.
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.
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.
Market trendOperation 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，Colorado SpringsWarehouse boarding bridge， 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.
The mobile boarding bridge suddenly loses control of the operating platform.
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.

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.
Install a m high protective railing around the foundation pit of the simple boarding bridge， with a distance of no less than m 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， no overbreak&rquote; The principle of.
