CAT CLASS: HQ-10220

5-8 cu yd Wheel Loader

The 5-8 cu yd wheel loader class represents the largest production loaders in general equipment fleets, designed for quarry face loading, aggregate stockpile management, and feeding plants rated at 300 tons per hour or higher. With bucket capacities from 4.2 to 6.2 cubic yards and engine power ranging from 201 to 293 hp, these machines sit at the top of the wheel loader ladder. Case and Volvo manufacture models in this size class.

Spécifications clés

Spécification	Plage typique	Signification
Bucket capacity	4.2–6.2 cu yd	Matched to high-volume loading cycles and large haul truck capacities
Engine power	201–293 hp	Provides breakout force and travel speed for production loading in hard material
Operating weight	66,580–135,915 lb (30,200–61,650 kg)	Heavy counterweight and frame mass stabilize the machine when handling full buckets
Fuel tank capacity	125–473 L	Extended fuel capacity supports multi-shift operation with fewer refueling interruptions

Comment choisir

This size class is appropriate for quarry production environments, large aggregate operations, and sites where material is moved continuously in high volumes to feed crushers, screens, or conveyors. Typical applications include loading 30- to 50-ton articulated haul trucks, stockpiling crushed rock, and face loading in open-pit mines. Operators working with smaller haul units, lower throughput plants, or confined quarry benches will find the 3-5 cu yd Wheel Loader more maneuverable and better matched to truck capacity. No larger size class is cataloged; operations requiring greater bucket capacity typically move to rigid-frame production loaders or front-end loaders outside the wheel loader category.

Ce que cette taille peut gérer

Loading 30- to 50-ton articulated dump trucks at a quarry face
Stockpiling crushed aggregate at a 300+ tph processing plant
Face loading shot rock in open-pit limestone or granite quarries
Feeding primary crushers with blasted material
Moving overburden and topsoil during large-scale site development
Loading railcars or barge hoppers with bulk aggregates

Sécurité et opération

ROPS/FOPS cab certification is standard; operators must maintain clear visibility during bucket loading and truck spotting
Ground personnel must remain outside the swing radius and behind designated berms or barriers during loading cycles
Tire pressures and tread condition are critical for stability on ramps, quarry floors, and uneven stockpile surfaces
Articulated steering geometry requires awareness of rear-frame swing during tight turns and in confined quarry benches

Transport et logistique

Requires heavy-duty lowboy or RGN trailer rated for 30,000–62,000 kg loads
Transport width and height often necessitate oversize load permits and escort vehicles
Loading typically performed with ramps or hydraulic tilt-deck trailers; machine self-loads where bed height allows

Alimentation

Diesel fuel consumption ranges from 20 to 40 L/hr under sustained production loading
On-site bulk fuel storage or scheduled tanker deliveries are standard for multi-shift quarry operations
Diesel exhaust fluid (DEF) required for Tier 4 Final emissions compliance on newer models

Questions fréquentes

What haul truck size matches a 5-8 cu yd loader?

This loader class typically pairs with 30- to 50-ton articulated haul trucks, allowing 3- to 5-pass loading cycles depending on material density and bucket fill factor.

How does operating weight affect loader performance in quarry conditions?

The 30,000–62,000 kg operating weight provides stability during full-bucket breakout and prevents rear-wheel lift, especially when loading hard or blasted rock that requires high breakout force.

What distinguishes this size from the 3-5 cu yd class in production environments?

The 5-8 cu yd class delivers approximately 50% greater bucket capacity and engine power, suited to operations where throughput exceeds 300 tph and haul trucks are 30 tons or larger; smaller loaders cycle faster but move less material per pass.
