1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

L'augmentation des coûts d'exploitation et les temps d'arrêt imprévisibles érodent-ils la rentabilité de votre carrière? Managing a professional quarry site in Lagos presents distinct challenges that standard equipment often fails to address. You face constant pressure from material haulage inefficiencies, severe wear from abrasive local aggregates, and the critical need to maintain consistent feed to your primary crusher. Each hour of loader or haul truck downtime directly impacts your plant's throughput and bottom line. How do you ensure continuous material movement in Lagos' demanding environment while controlling maintenance costs and fuel consumption? The solution requires equipment engineered not just for mining, but for the specific logistical and material challenges of Lagosarea quarries.

2. APERÇU DU PRODUIT

La solution est un HeavyDuty Articulated Dump Truck (ADT) specifically configured for professional quarry sites in Lagos. This machine is engineered for highvolume transport of blasted rock, surcharger, and aggregates across rough, mouillé, and unstable haul roads typical of local operations.

Flux de travail opérationnel:
1. Chargement: The ADT is loaded by an excavator or wheel loader at the quarry face or primary crusher stockpile.
2. Traction: Its articulated chassis and allwheel drive provide superior traction and stability on steep, muddy, or poorly maintained site roads, transporting payloads to processing plants or stockpiles.
3. Maneuvering & Dumping: Excellent maneuverability allows for precise positioning in tight tipping areas. The robust body raises to discharge material into hoppers or onto stockpiles.
4. Cycle de retour: The empty truck returns via the same challenging terrain, completing the cycle with minimal speed reduction.

Champ d'application: Ideal for highvolume earthmoving and rock haulage over shorttomedium distances (100m – 1500m) within a quarry boundary. It excels where road conditions are poor and site layout requires tight turning.
Limites: For longdistance haulage on established hard roads (>2kilomètres), rigid dump trucks may offer higher sustained speeds and lower costpertonne.

3. CARACTÉRISTIQUES PRINCIPALES

AllWheel Drive & Differential Locks | Base technique: Permanent 6x6 drive with selectable interaxle and crossaxle differential locks | Avantage opérationnel: Maintains forward momentum and traction in deep mud, standing water, and on loose grade slopes common in the rainy season | Impact sur le retour sur investissement: Reduces weatherrelated stoppages by an estimated 30%, ensuring more operating days per year.
Articulated Oscillating Chassis | Base technique: Center pivot joint with significant oscillating movement between front and rear frames | Avantage opérationnel: Keeps all wheels grounded on severely uneven terrain, enhancing stability and operator safety while reducing frame stress | Impact sur le retour sur investissement: Lowers risk of catastrophic frame damage and extends chassis service life by up to 40% compared to rigid frames on rough routes.
FuelEfficient Tier 3/Stage IIIA Engine | Base technique: Turbocharged diesel engine with optimized torque curve for loadandcarry cycles | Avantage opérationnel: Delivers high torque at low RPMs for hill climbs while minimizing fuel burn during idle and short hauls | Impact sur le retour sur investissement: Les données de terrain montrent 1218% lower fuel consumption per ton hauled versus older generation trucks.
Hardox® Body with AbrasionResistant Liners | Base technique: Highstrength steel body with boltin wear plates at impact points | Avantage opérationnel: Withstands impact from large, sharp Lagos granite and provides easier liner replacement during scheduled maintenance | Impact sur le retour sur investissement: Reduces unplanned body welding repairs by approximately 60% and extends total body life.
Scellé & Pressurized Cab | Base technique: ISOcertified cab with positive air pressure and advanced filtration system | Avantage opérationnel: Protects operators from excessive dust inhalation and reduces cabin heat load, directly impacting alertness and productivity | Impact sur le retour sur investissement: Contributes to higher sustained operator output over a full shift.
