Container reach crane is a type of crane used to load and unload containers, and is a type of lifting equipment. Container reach crane is specially designed for 20-foot and 40-foot international containers, and is mainly used for stacking containers and horizontal transportation within docks and yards. It can perform cross-container operations, and is particularly used for container loading and unloading at small and medium-sized ports, railway and highway stations, and can also be used as auxiliary equipment at large container terminals.
Une grue à conteneurs est un type de grue utilisée pour charger et décharger des conteneurs et est un type d’équipement de levage. Les grues à conteneurs sont spécialement conçues pour les conteneurs internationaux de 20 et 40 pieds et sont principalement utilisées pour l’empilage de conteneurs et le transport horizontal dans les quais et les cours. Il peut effectuer des opérations inter-conteneurs et est particulièrement utilisé pour le chargement et le déchargement de conteneurs dans les ports de petite et moyenne taille, les gares ferroviaires et les gares routières. Il peut également être utilisé comme équipement auxiliaire dans les grands terminaux à conteneurs.
The engine of a container reach stacker (reach loader) is its core power component, and its maintenance directly affects the equipment’s performance, lifespan, and operational safety.
The following are the key points for the maintenance of the front loaders engine:
1. Daily inspection and basic maintenance/ Inspection quotidienne et entretien de base
Oil inspection/Inspection de l’huile
Engine oil: Check the oil level before starting each day (when the engine is cold) to ensure that it is within the dipstick scale range and observe the color of the engine oil (if it turns black or emulsified, replace it immediately).
Coolant: Check the expansion tank level to avoid high temperature or lack of water.
Fuel: Check the diesel fuel level and the oil-water separator, and drain the water in time (especially in high humidity environments).
Leakage Check/Vérification des fuites
Check whether there are signs of fuel, oil or coolant leakage around the engine, paying special attention to leak points such as pipe joints and seals.
Clean the radiator surface debris (such as catkins, dust) every quarter using compressed air or a low-pressure water gun to avoid damaging the fins.
Filter status/État du filtre
Visually check whether the air filter is clogged (tap the filter gently, if there is too much dust, it needs to be replaced), and replace the fuel filter and oil filter according to the period.
Preparation for safe operation/Préparation à une opération sécuritaire
Before maintenance, ensure that the equipment is parked in a safe area, turn off the power, hang warning signs, and set tire blocks to prevent sliding.
2. Regular maintenance plan/Plan d’entretien régulier
Oil and filter replacement/Remplacement de l’huile et du filtre
Period: Every 250 hours or 3 months (whichever comes first).
Operation: After stopping the machine, drain the old engine oil while it is still hot. When replacing the filter element, clean the sealing surface of the filter element seat and add diesel engine oil that meets API standards.
Fuel System Maintenance/Entretien du système de carburant
Fuel filter: Replace every 500 hours. Choose original or adapted brands to avoid fuel injector clogging caused by inferior filter elements.
Fuel tank cleaning: Clean impurities at the bottom of the fuel tank every year to prevent moisture and contaminants from entering the high-pressure fuel pump.
Cooling system maintenance/Entretien du système de refroidissement
Radiator cleaning: Use compressed air or a low-pressure water gun to remove dust, catkins and other debris between the radiator fins every quarter (to avoid damaging the fins).
Antifreeze replacement: Replace the long-lasting antifreeze every 2 years or 4000 hours (the freezing point must meet the local minimum temperature), and check the water tank level regularly to avoid scaling that affects heat dissipation.
Air filter management/Gestion du filtre à air
Replacement cycle: Adjust according to working conditions (shorten to 100 hours in dusty environment); replace immediately when pressure difference alarm occurs.
Cleaning method: Do not wash with water, use compressed air to blow from the inside to the outside (pressure ≤ 0.5MPa).
Crankcase and ventilation system/Carter et système de ventilation
Clean the crankcase regularly to remove sludge and carbon deposits to avoid clogging the oil holes. Check the PCV valve (forced crankcase ventilation valve) every 1,000 hours to prevent contaminants from flowing back and contaminating the filter element.
3. In-depth maintenance of key systems/Maintenance approfondie des systèmes clés
Turbocharger inspection/Inspection du turbocompresseur
Check the supercharger bearing clearance every 1000 hours. Abnormal vibration or oil leakage requires professional maintenance.
Belt and tensioner/Courroie et tendeur
Check whether the fan belt and generator belt are cracked or loose, and adjust the tension (it is normal if the midpoint sinks 10-15mm when pressed).
Fuel injection system calibration/Calibrage du système d’injection de carburant
The atomization effect and injection pressure of the fuel injector nozzles should be checked every 2000 hours and calibrated by a professional technician if necessary to avoid black smoke caused by incomplete combustion.
Electrical and ignition systems/Systèmes électriques et d’allumage
Check the battery fluid level and terminal connectors regularly (apply Vaseline to prevent oxidation). The spark plug gap must meet the standard (e.g. 0.33mm) and should be replaced every 60,000 kilometers.
4. Operation and fault prevention/Fonctionnement et prévention des pannes
Reasonable operating habits/Habitudes de fonctionnement raisonnables
Avoid high-load operation immediately after a cold start, and preheat at idle for 3-5 minutes (extend to 10 minutes in winter).
Run the engine at idle speed for 2-3 minutes before shutting down to prevent the turbocharger from overheating and being damaged.
Avoid removing the thermostat to ensure that the cooling system operates at an appropriate temperature and prevent low temperatures from exacerbating wear.
Common fault warning/Avertissement de défaut courant
Water temperature is too high: check the radiator, water pump, thermostat and coolant circulation.
Low oil pressure: Check for blockage in the oil pump or filter element or wear on the bearings.
Black smoke: Incomplete combustion may be caused by air filter blockage, mistimed fuel injection or supercharger failure.
5. Professional advice/Conseils professionnels
Use original parts: Non-original filters or inferior engine oil may cause abnormal engine wear.
Data records: Establish maintenance files to record each maintenance time, replacement parts and abnormal conditions.
Regular professional testing: entrust the manufacturer or authorized service provider to conduct engine performance testing (such as cylinder pressure and exhaust gas analysis) every year.
Summarize:
Through systematic maintenance, the engine life can be significantly extended (usually up to more than 10,000 hours), the risk of sudden failure can be reduced, and the efficient and stable operation of the container reach stacker can be guaranteed.
Grâce à une maintenance systématique, la durée de vie du moteur peut être considérablement prolongée (généralement jusqu’à plus de 10 000 heures), le risque de panne soudaine peut être réduit et le fonctionnement efficace et stable du gerbeur à conteneurs peut être garanti.
