CAT CLASS: HQ-10219

3-5 cu yd Wheel Loader

The 3-5 cu yd wheel loader is the everyday production loader on construction sites, quarries, and material yards. Sized to load tandem-axle dump trucks efficiently and feed crushers with sustained throughput, this class balances cycle speed with payload. It occupies the third rung on the wheel loader ladder, above compact loaders and below heavy production machines.

Spécifications clés

Spécification	Plage typique	Signification
Bucket capacity	3.5–4.5 cu yd	Matches the load volume for tandem dump trucks and aggregate handling
Engine power	124–180 hp	Provides hydraulic flow and torque for sustained production cycles
Operating weight	48,281–71,943 lb (21,900–32,633 kg)	Mass that counterbalances bucket loads and stabilizes the machine during lifting

Comment choisir

Select the 3-5 cu yd wheel loader when the primary task involves loading tandem-axle dump trucks, feeding crushers, or moving bulk material in medium to large volumes with fast cycle times. This size suits sites where production rate and machine stability under full bucket loads are priorities. Step down to the 1.5-3 cu yd Wheel Loader for tighter access, lighter truck loads, or when the work area limits machine size. Step up to the 5-8 cu yd Wheel Loader when loading articulated dump trucks, tri-axle highway dumps, or when material density and volume demand greater breakout force and bucket capacity.

Ce que cette taille peut gérer

Loading tandem-axle dump trucks in quarries and material pits
Feeding aggregate crushers with sustained production throughput
Stockpiling crushed stone, gravel, or sand in large material yards
Excavation support on highway and commercial building projects
Loading haul trucks with topsoil, fill, or demolition debris
Material handling in asphalt plants and concrete batch operations

Sécurité et opération

ROPS/FOPS cab standard; operator must maintain seatbelt use and verify rollover protection integrity
Articulated steering creates rear-swing hazard; spotter or exclusion zones required when working near personnel or structures
Bucket loads shift center of gravity; avoid travel on grades steeper than manufacturer limits, especially with raised bucket
Daily inspection of hydraulic hoses, bucket pins, tire condition, and brake function required before operation

Transport et logistique

Requires lowboy or heavy equipment trailer; most models exceed legal width and weight for unassisted highway transport
Transport weight typically 21,900–32,633 kg; trailer and towing vehicle must meet state gross combination weight regulations
Loading via drive-on ramps; articulated frame and turning radius require adequate trailer deck length

Alimentation

Diesel fuel; onsite refueling or fuel service typically required for full-shift operation
Fuel consumption varies with cycle intensity, material density, and grade; daily consumption generally 40–80 liters under sustained production
Cold-weather operation may require block heaters or auxiliary starting systems

Questions fréquentes

How many passes does a 3-5 cu yd loader need to load a tandem dump truck?

Typically 3–4 bucket passes to fill a 10–15 cubic yard tandem-axle dump truck body, depending on material density and bucket heaping.

What tire type is standard on this size class?

Most models in this class use L3 or L4 radial or bias-ply tires sized for load capacity and site conditions; rock operations often specify L5 tires for cut resistance.

Can this loader operate on slopes or uneven ground?

Articulated frame design and weight distribution allow operation on moderate slopes, but manufacturers specify maximum grade limits (often 15–20°); stability decreases with raised bucket or soft ground.
