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, 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.

The length of the electric hydraulic boarding bridge is generally about 10 meters, and the bearing weight varies depending on the tonnage. It is 10500mm for 6 tons, 11200m for 8 tons, and 11300m for 10 tons. It is very suitable for placement on the ground in open spaces.

Haoda.The mobile boarding bridge suddenly loses control of the operating platform.

The hydraulic lifting boarding bridge is a specialized auxiliary equipment for fast loading and unloading of goods. Its height adjustment function allows a bridge to be built between the truck and the cargo platform in the warehouse. Forklifts and other handling vehicles can directly enter the truck for batch loading and unloading of goods, and single person operations can achieve fast loading and unloading of goods. Reduce a large amount of labor, improve work efficiency, and achieve greater economic benefits for enterprises.

.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.

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, use a voltmeter to check whether the lowering valve is energized. If there is no power, 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.

  1. Before use,HaodaFixed boarding bridge, check the boarding bridge for obvious damage such as cracks and broken wires.

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 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,HaodaMovable hydraulic boarding bridge, the amount of oil should not be too much, as too much can also cause problems.

When working in foundation pits or depths, a helmet must be worn.

Affordable price.Check if the manual valve is open. When using, it must be opened, otherwise the boarding bridge may be damaged.

The length of the electric hydraulic boarding bridge is generally about 10 meters and the bearing weight varies depending on the tonnage. It is 10500mm for 6 tons, 11200m for 8 tons,HaodaMoving the boarding bridge, and 11300m for 10 tons. It is very suitable for placement on the ground in open spaces.

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.

The user department of the hydraulic boarding bridge should scientifically analyze the equipment and reasonably determine the investment in the equipment. At the same time, 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.

Quality inspection report.These are the options for hydraulic oil for mobile boarding bridges.

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, 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.

Haoda.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, construction must be suspended and reported to the superior for handling.

  1. Before use, check the boarding bridge for obvious damage such as cracks and broken wires.

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.
