Caterpillar 777C Haul Truck Review: Plan Your Next Quarry Fleet Enquiry

Moving bulk material starts with a clear haulage plan. The loading equipment, travel route and discharge area all shape a fleet purchase. This Caterpillar 777C offer gives buyers a specific used off-highway truck to assess against that plan.
Omnia Machinery advertises the truck at US$150,000, with a 1994 registration year and a seller-described Cat 3508 DITA diesel engine. The seller’s page identifies Kentucky, USA, and the photographs show a rigid haul truck with visible 777C markings.
Review method: a desk-based assessment of Machineryline RW47184, Omnia US2333, seller photographs, Caterpillar parts information and HSE quarry guidance. We have not operated or independently inspected the truck. No operating-readiness claim is made.

The seller’s own description gives Kentucky, while Machineryline displays Miami as the contact location. Request the actual truck address, inspection access and collection arrangements before planning a visit or transport.

What stands out in the actual photographs?
A rigid layout for off-highway haulage
The photographs show a large rigid-frame truck with a rear dump body. A buyer can use those views to prepare an enquiry about bulk-material transport within a quarry or mine, subject to the actual truck’s confirmed configuration and condition.
Describe the material, bulk density, loading equipment and intended route to the supplier. Request the rated payload, fitted body volume and loading height for this serial number. This review does not substitute figures from newer 777 generations for the advertised 777C.
Access, cab and front arrangement
The front view shows access ladders, handrails, lighting and the 777C marking. Include these areas in the inspection and handover: access condition, cab restraints, visibility aids, alarms, lighting and the controls fitted to the actual truck.
Ask for current cab photographs and a demonstration of the instruments and safety devices. Request cab identification and protection documentation rather than assigning a certification from appearance alone.

Rear tyres, axle and body arrangement
The rear photograph shows paired rear tyres, the axle area and the underside of the dump body. Ask the inspector to document the tyres, suspension, frame, body, hoist components and relevant maintenance records.
Match tyre selection and loading to the proposed material and route, using the applicable manufacturer and tyre-supplier guidance. Obtain the truck’s dimensions, turning envelope and transport configuration before arranging delivery.

Manufacturer information: braking and serial-specific support
Caterpillar’s Parts Store identifies front service-brake group 177-2249 as compatible with the 777C family and describes an oil-actuated disc-brake mechanism. This is a documented manufacturer reference, not confirmation that the advertised truck has a particular replacement group fitted.
Ask a Cat dealer or competent inspector to identify the truck’s braking system from its serial number and fitted components. Request condition and function checks for service braking, parking braking, secondary braking and retarding arrangements, as applicable to that machine.
Caterpillar’s 777C parts resources allow serial-number entry to help identify the correct diagrams and parts. Use that identification to obtain applicable operation and maintenance information, cooling-system parts and service support for the actual truck.
Make the cooling-system scope concrete
The seller’s cooling-condition statement belongs in the purchase brief. Ask what diagnostic work has been completed, whether a report is available and what preparation the supplier proposes before handover.
Agree who will carry out any repairs, which work is included, how completion will be documented and what inspection or acceptance checks will follow. A clear repair scope helps you assess the complete purchase and delivery plan without treating the seller’s suggested cause as a confirmed diagnosis.
Where could a confirmed 777C configuration fit?
A rigid haul truck can be considered for quarry and surface-mine material transport where the truck, loading system and route are compatible. For this offer, establish condition and preparation first, then match the confirmed working specifications to the task.
- Quarry fleet planning: define the material, loading equipment, haul distance and discharge area.
- Surface-mine support: provide route gradients, turning space, clearances and maintenance arrangements.
- Equipment procurement: evaluate the documented machine, agreed preparation and delivered package together.
For example, a quarry manager can send the supplier the loader bucket specification, material density, route profile and target work cycle. That gives the supplier a practical basis for confirming body configuration, payload and the proposed handover condition.
Watch a separate 777C transport reference
Watch Mega Machines Channel’s Cat 777C land-and-sea transport film. This is independent footage of a separate truck, not Omnia US2333. It provides visual transport context; it does not verify this listing, establish transport requirements for your purchase or replace a competent transport plan.
Buying checks before you agree the quotation
- Identity: readable model, serial and engine plates, ownership records and registration/manufacture details.
- Hours and history: current meter reading, service records and available component overhaul information.
- Cooling condition: diagnostic report, agreed repair scope, responsibility and post-repair acceptance checks.
- Working specifications: actual payload, body volume, dimensions, loading height and route compatibility.
- Inspection: engine, cooling system, transmission, brakes, steering, suspension, chassis, body, hoist and tyres.
- Support and delivery: applicable manuals, parts arrangements, support/warranty terms, transport weight and complete delivery scope.
Prepare the quarry route and operating arrangements
HSE’s quarry guidance emphasises brake inspection and testing, regular maintenance and matching vehicles to haul-road conditions. Its vehicle guidance also addresses traffic routes, visibility, reversing and edge protection.
Have competent personnel assess road widths, gradients, surfaces and tipping areas for the confirmed truck. Integrate pedestrian separation, loading limits, inspections and operator training into the site plan. Follow the actual machine’s manual and isolation instructions, including the approved body-support arrangement for maintenance.
Our view: assess the whole prepared-machine offer
This listing provides actual truck photographs, a stated engine configuration and an identifiable seller reference. The confirmed seller information gives a useful starting point for an equipment enquiry.
Make the cooling-system diagnosis and preparation scope part of that enquiry, alongside the serial-specific specifications and inspection. A complete written proposal helps you assess how this 777C could fit your fleet plan and what must be completed before handover.
