it must be opened, otherwise the boarding bridge may be damaged.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.Prov,Application of hydraulic boarding bridges: Hydraulic boarding bridges can be widely used in docks, platforms, warehouses, etc. according to user needs. Special designs can be made in terms of external dimensions, load, etc. The fixed boarding bridge is installed on the side of the cargo platform, flush with the ground and side of the cargo platform. The bridge deck of a fixed boarding bridge can tilt up and down, and its outer end can be higher or lower than the plane of the cargo platform, making it equal to the height of the carriage. There is a flip board at the top of the bridge which automatically attaches to the edge of the carriage, the air conditioning panel will automatically rise. Release the button ensuring a smooth passage between the cargo platform and the carriage.The electronic operation is very simple. With just one button, adjust the plate to reduce itself, and the hinge is used on the truck.Cumanayagua,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, we should regularly clean the safety valve, slowly lower the boarding bridge, and secure more than % of the lip plates at the bottom of the container.

The slope of the electric hydraulic boarding bridge itself must have a certain slope to allow the forklift to enter the carriage for cargo loading and unloading. The length of the slope also varies from mm to mm, mainly considering safety and stability of use. For a long time, the manufacturer of the boarding axle has no turnover to avoid the price difference, which is % higher than the market value! More than one ton is more expensive!Check the rollers, intermediate shafts, and bearings; Oil cylinder pin and bearing; Equality and wear of the hinge shaft and bearings of the boom; Add oil to the above components for maintenance of outdoor elevators and factory elevators. Extend the service life of bearings. Professional axle manufacturers and other special products, old brands, with price advantages and guaranteed qualityDuring use, close attention should be paid to the condition of the equipment, and if there are any problems, the use should be stopped immediately.Test conclusion,　　. Before use, check the boarding bridge for obvious damage such as cracks and broken wires.When working on the hydraulic boarding bridge, the support legs must be extended, and the support leg bolts must be adjusted to ensure that the lifting platform is stably stressed on the support legs and kept horizontal; During the lifting process and in the lifting state,ProvHydraulic lifting boarding bridge, the lifting platform must not be moved, and it is strictly prohibited to shake on the lifting platform. If there is an abnormal sound during the operation of the hydraulic boarding bridge,ProvMobile lifting boarding bridge, it should be stopped immediately for inspection to avoid causing serious damage to the lifting platform; Before use, it is necessary to perform no-load lifting and check whether the hydraulic system is normal; The load of the workbench should not exceed the rated value and it should not be subjected to intense manual shaking; The hydraulic oil in the oil tank must be replaced every hours of operation.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.

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.Interpretation and observation,The slope of the electric hydraulic boarding bridge itself must have a certain slope to allow the forklift to enter the carriage for cargo loading and unloading. The length of the slope also varies from mm to mm,ProvHydraulic mobile boarding bridge, mainly considering safety and stability of use. For a long time, the manufacturer of the boarding axle has no turnover to avoid the price difference, which is % higher than the market value! More than one ton is more expensive!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.Prov, 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.
