A container reach crane is a type of crane used to load and unload containers and is a type of lifting equipment.
The gearbox of a container reach stacker (reach loader) is the core component of its power transmission system. Its maintenance directly affects the working efficiency and service life of the equipment.
The following is a detailed guide to gearbox maintenance:
1. Daily inspection and basic maintenance/Inspection quotidienne et entretien de base
Oil level check/Contrôle du niveau d’huile
Frequency: Daily before start-up or after each shift.
Method: Let the engine idle, pull out the gearbox oil dipstick or observation window to check the gearbox oil level, and make sure the oil is between “MAX” and “MIN”. If the oil level is below the minimum scale, add oil according to regulations.
Note: When the oil is insufficient, add the lubricating oil of the original model specified by the manufacturer in time.
Leakage Check/Vérification des fuites
Check the gearbox housing, oil pan, oil pipe joints and seals for leaks. If leaks are found, repair them immediately.
Abnormal sound and vibration monitoring/Surveillance des bruits et vibrations anormaux
During operation, pay attention to whether the gearbox has abnormal noise (such as metal friction, knocking sound) or abnormal vibration, which may indicate problems such as gear wear and bearing damage.
2. Regular maintenance items/Éléments d’entretien réguliers
Replace lubricating oil and filter/Remplacer l’huile de lubrification et le filtre
Cycle: Filter blockage will reduce the amount of oil required for gear shifting and lubrication. Replace the transmission filter every 500-1000 hours or as required by the manufacturer’s manual (shorter cycle for severe working conditions).
step:
After the machine is warmed up, stop the machine and drain the old oil.
Replace the filter element (some models may not have a separate filter element).
Clean the magnetic drain plug of the oil pan (it absorbs metal debris).
Add new oil to the specified amount and avoid mixing oils of different brands.
Clutch maintenance/Entretien de l’embrayage
Inspection cycle: every 1000 hours or half a year.
content:
Check the clutch plate wear thickness, if it is below the limit, replace it.
Adjust the clutch pedal free travel (usually 20-30mm) to ensure complete separation and smooth engagement.
Transmission parts inspection/Inspection des pièces de transmission
Gears and bearings: disassemble and inspect the gearbox (professionals are recommended to do this), check whether the gear meshing surfaces have pitting or peeling, and whether the bearings are stuck or making abnormal noises.
Under the action of load and vibration, loose bolts are easy to be sheared off. Before the transmission shaft transmits torque, its fixing bolts must be carefully checked to avoid accidents.
Check whether the fixing bolts and fixing seats are loose/Vérifiez si les boulons de fixation et les sièges de fixation sont desserrés
The function of the fixing seat and the shock-absorbing pad is to fix the gearbox on the frame and to reduce shock when the gearbox starts, runs and stops.
Check items: Whether the fixing seat and shock-absorbing pad are damaged; whether the relevant bolts are loose.
Synchronizer: If there is gear knocking or difficulty in shifting gears, it may be necessary to replace the synchronizer ring or repair the shift fork.
3. Operation precautions/Précautions d’utilisation
Standardized gear shifting operation/Fonctionnement standardisé du changement de vitesse
Make sure the clutch is completely disengaged before shifting gears to avoid forcing the gears into position or running the vehicle in a semi-clutch state for a long time.
Reduce sudden acceleration and deceleration to prevent impact loads from damaging gears.
Cooling system maintenance/Entretien du système de refroidissement
Regularly clean the dust and oil on the surface of the transmission radiator to ensure the normal operation of the cooling fan.
Monitor the oil temperature gauge. The normal operating temperature is generally 70-90°C. If the temperature remains high, check the cooling system or oil line blockage.
4. Professional testing and diagnosis/Tests et diagnostics professionnels
Oil Analysis/Analyse d’huile
Take samples for inspection every year or every 2000 hours, and determine the internal wear trend by testing the metal particle content.
Fault diagnosis instrument/Instrument de diagnostic de pannes
Use the manufacturer’s dedicated equipment to read the fault code of the transmission control unit (if there is an electronic control system) and check for sensor or valve body problems.
5. Long-term deactivation and storage/Désactivation et stockage à long terme
Replace the lubricating oil with new one before parking and drain the old oil to avoid acidification and corrosion.
Start the equipment once a month and run it for 10-15 minutes to lubricate the inside of the gearbox.
Cover the transmission vent holes to prevent the intrusion of dust and moisture.
6. Security and records management/Sécurité et gestion des dossiers
Overloading is strictly prohibited: overloading operation will aggravate the fatigue damage of gearbox gears and bearings.
Maintenance records: Record each maintenance time, replaced parts and oil model in detail to facilitate problem tracing.
Operation training: Ensure that the driver is familiar with the correct gear shifting process to avoid mechanical failure caused by improper operation.
7. Emergency handling/Gestion des urgences
If the following situations occur during operation, the machine must be stopped for maintenance immediately:
The transmission emits smoke or the oil temperature rises abnormally.
The vehicle cannot be driven or power transmission is interrupted after engaging a gear.
The oil is severely emulsified (water ingress) or contains a large amount of metal debris.
Summarize
The maintenance of the container reach stacker gearbox requires a combination of daily inspection, regular maintenance, standardized operation and professional diagnosis. Following the manufacturer’s manual requirements and using genuine parts and oils can significantly reduce the failure rate and extend the service life of the equipment. For complex failures, it is recommended to contact an authorized service provider to avoid secondary damage caused by improper repairs.
L’entretien de la boîte de vitesses du reach stacker pour conteneurs nécessite une combinaison d’inspection quotidienne, d’entretien régulier, d’exploitation standardisée et de diagnostic professionnel. Le respect des exigences du manuel du fabricant et l’utilisation de pièces et d’huiles d’origine peuvent réduire considérablement le taux de défaillance et prolonger la durée de vie de l’équipement. Pour les pannes complexes, il est recommandé de contacter un prestataire de services agréé afin d’éviter des dommages secondaires causés par des réparations inappropriées.
