The Caterpillar 793D is one of the most widely used off-highway mining trucks in the world. Known for its payload capacity, durability, and performance in high-production haulage, the 793D continues to be a cornerstone of surface mining operations globally.

With demand for reliable, late-model truck components at an all-time high, DGI Trading is supporting the industry by dismantling multiple 793D trucks to supply high-quality used parts. These machines are now being dismantled to ensure a wide range of critical components are made available for customers running active Caterpillar fleets.

About the Caterpillar 793D

The Caterpillar 793D is a mechanical drive rigid-frame haul truck that sits in the 240 tonne class. Designed for large-scale open cut mining, it has become the go-to choice for iron ore, coal, and gold operations where payload, cycle time, and machine availability directly impact profitability.

Key specifications:

• Gross machine operating weight: approx. 385 tonnes
• Nominal payload: 240 tonnes
• Engine output: 2,400 horsepower (Cat 3516B)
• Transmission: 6-speed planetary powershift
• Top speed: approx. 60 km/h (loaded)

Its high-capacity design, combined with a proven service history, makes the 793D one of the most cost-effective large mining trucks in operation today. As fleets age, component reuse and replacement becomes critical to extending machine life without the cost of full replacement.

DGI Trading: 793D Truck Dismantling Now Underway

DGI is currently dismantling three Caterpillar 793D trucks. These machines are now being processed to recover and supply a broad inventory of late-model, good used components. This dismantling project allows mining operators to access cost-effective, production-ready parts with minimal lead time.

Components being made available through this program include:

• Chassis assemblies and rear frames
• Wheel groups (front and rear)
• Final drives and brake groups
• Differentials and torque converters
• Complete radiators and cooling systems
• Cylinder groups – hoist, steering, suspension
• Fuel tanks and hydraulic tanks
• Pump groups and drive lines
• Transmissions and related hardware
• Operator cabs and cab modules
• Engine modules (Cat 3516B)
• Steering arms, linkages, and suspension components

These components are suitable for direct fitment or rebuild, depending on site requirements.

Benefits of Used 793D Components

For mining operations managing mid-life 793D trucks, sourcing OEM parts can involve long wait times, high cost, or limited availability. Used and low-hour components from professionally dismantled units offer a cost-effective, lower-lead-time solution that still meets reliability and safety standards.

Advantages include:

• Reduced downtime: Fast access to pre-owned parts avoids long delays associated with new build or remanufacture
• Cost control: Used components offer significant savings compared to new OEM equivalents
• Extended machine life: Keeps legacy fleets running in line with production plans
• Site compliance: DGI provides detailed inspection records and condition reports
• Global logistics: Parts are packed and shipped with full export documentation if required

For sites running multiple 793D trucks, these parts can also be used to create critical spares kits to minimise risk of extended stoppages during peak production.

Supporting Your Fleet Through Lifecycle Maintenance

As fleets of 793D trucks move through their operating lifecycle, the focus shifts from capital acquisition to component-based maintenance strategies. Maintaining consistent uptime requires access to quality parts, whether through planned shutdowns or urgent breakdown support.

DGI Trading supports this need by:

• Sourcing and dismantling late-model 793D units for parts
• Maintaining stock of high-turnover components across Australia
• Providing direct-to-site dispatch with tracked logistics
• Offering expert support to identify component matches
• Ensuring all parts meet operational readiness and condition expectations

Our team works with maintenance managers, superintendents, and procurement leads across the mining sector to keep fleets moving with minimal disruption.
