In recent years, container transportation has made great progress in railway transportation, and the reach stacker for loading and unloading containers has been used more and more widely. The reach stacker has a complex structure and is a high-efficiency production equipment that integrates machinery, electricity and hydraulics.
En los últimos años, el transporte de contenedores ha logrado grandes avances en el transporte ferroviario y los apiladores retráctiles para cargar y descargar contenedores se han utilizado cada vez más. El reach stacker tiene una estructura compleja y es un equipo de producción altamente eficiente que integra maquinaria, electricidad e hidráulica.
1. Drive axle structure and maintenance focus
Estructura del eje de transmisión y enfoque de mantenimiento
The drive axle is a key component for front crane power transmission, mainly including the main reducer (differential), half shaft, wheel reducer, brake system, etc. The core of maintenance lies in lubrication management, sealing inspection, gear wear monitoring and brake system function guarantee.
2. Daily inspection and basic maintenance/Inspección diaria y mantenimiento básico
Lubricating oil level check/Comprobación del nivel de aceite lubricante
Frequency: Check the lubrication oil level before daily operation or at the end of each shift.
Method: Check the oil level through the oil level observation window or dipstick of the drive axle housing to ensure that the oil level is between “MAX” and “MIN”. If the oil level is lower than “MIN”, add oil in time and use the original factory-specified gear oil to avoid mixing different brands or models.
Leakage Check/Comprobación de fugas
Check the drive axle housing, wheel reducer, half-axle oil seal and pipe joints for leaks. If leaks are found, repair them immediately to prevent gear wear due to insufficient oil.
Abnormal sound and vibration monitoring/Monitoreo de sonidos y vibraciones anormales
During operation, pay attention to whether the drive axle makes abnormal noises (for example, a “clicking” sound may be caused by wear of the differential gear, and a “buzzing” sound may be caused by bearing damage).
Abnormal vibration may be caused by poor meshing of the wheel reducer gears or deformation of the half shaft.
Brake system inspection/Inspección del sistema de frenos
Check the wear of the brake drum/disc and brake pads, ensure that there are no leaks in the brake lines, and that the brake fluid (hydraulic brake system) level is normal.
3. Regular maintenance items/Elementos de mantenimiento regular
Change gear oil/Cambiar el aceite de la caja de cambios
Cycle: Every 1000-2000 hours or as per the manufacturer’s manual (shortened to 500 hours in harsh working conditions such as high temperature and dusty environment).
step:
After warming up the machine, stop the machine and drain the old oil.
Clean the magnetic oil drain plug at the bottom of the drive axle (to absorb metal debris).
Add new oil to the specified amount to avoid excessive oil which may cause the oil seal to leak under pressure.
Wheel reducer maintenance/Mantenimiento del reductor de ruedas
Cycle: Every 2000 hours or every year.
content:
Check the wheel reducer gears for wear and pitting.
Replace the wheel oil seal to prevent grease leakage or external contaminants from entering.
Refill or replace wheel grease (such as NLGI Grade 2 lithium grease).
Differential and half shaft inspection/Inspección del diferencial y del semieje
Cycle: Every 3000 hours or as needed.
Key points:
Check the differential gear meshing clearance and adjust the preload (special tools are required).
Check the half-shaft spline for wear, bending and deformation, and replace if necessary.
Bearing maintenance/Mantenimiento de rodamientos
Check the clearance and lubrication status of the main reducer bearing and wheel hub bearing, and reapply high-temperature grease to avoid overheating and seizure.
4. Operation precautions/Precauciones de operación
Avoid overloading and shock loading/Evite sobrecargas y cargas de choque
Overloading will accelerate the fatigue fracture of the main reducer gear, and sudden acceleration or braking can easily cause torsional deformation of the half-shaft.
Standardized steering and driving/Dirección y conducción estandarizadas
Reduce steering on the spot and reduce the additional load on the differential gears and half shafts.
Slow down when driving on uneven roads to avoid impact on the drive axle.
Braking system protection/Protección del sistema de frenado
Avoid long-term continuous braking that may cause overheating of the wheel rim, prevent brake pad burning and hub bearing grease failure.
5. Professional detection and fault prevention/Detección profesional y prevención de fallos
Oil Analysis/Análisis de aceite
Regularly sample gear oil to detect metal particle content (such as iron and copper elements) to determine the wear trend of gears or bearings.
Gear meshing mark inspection/Inspección de la marca de engrane de los engranajes
Observe the position and area of the gear contact spots by disassembly and inspection, and adjust the meshing clearance to the manufacturer’s standard.
Wheel end temperature monitoring/Monitoreo de la temperatura del extremo de la rueda
Use an infrared thermometer to measure the temperature of the wheel reducer regularly. Abnormal temperature rise may indicate poor lubrication or bearing damage.
6. Long-term deactivation and storage/Desactivación y almacenamiento a largo plazo
Replace the gear oil with new one before stopping use and drain the old oil to prevent acidification and corrosion of the gears.
Start the equipment and move it a short distance every month to avoid grease stratification of the wheel reducer or aging of the seals.
Cover the drive axle vents to prevent moisture and dust from entering.
7. Emergency handling/Manejo de emergencias
The following situations require immediate shutdown and maintenance:
The drive axle is leaking oil seriously and the oil level is below the minimum mark.
One side of the wheel gets stuck or the power transmission is interrupted during driving (possibly a broken half-axle).
Brake failure or abnormally high wheel temperature (possibly due to brake locking or bearing damage).
8. Maintenance records and safety regulations/
Registros de mantenimiento y normas de seguridad
Record management: Record each maintenance time, replacement parts model and oil brand in detail to establish a drive axle health file.
Safe operation: During maintenance, ensure that the equipment is stopped and the brake system is locked to prevent accidental movement.
Professional support: Complex operations such as gear clearance adjustment and bearing preload calibration need to be completed by professional technicians.
Summarize:/Resumir:
The maintenance of the drive axle should focus on lubrication, sealing and wear monitoring. Combining daily inspection with regular maintenance can significantly reduce the failure rate. Following the manufacturer’s manual standards, using genuine parts and oils, and strengthening operator training are the keys to extending the life of the drive axle. It is recommended to contact the manufacturer or authorized service provider for complex faults.
El mantenimiento del eje motriz debe centrarse en la lubricación, el sellado y el control del desgaste. La combinación de la inspección diaria con el mantenimiento regular puede reducir significativamente la tasa de fallas. Seguir los estándares del manual del fabricante, utilizar piezas y fluidos originales y fortalecer la capacitación del operador son las claves para prolongar la vida útil del eje motriz. Para fallas complejas, se recomienda contactar al fabricante o al proveedor de servicio autorizado.
