AJAX ARGO 4500 vs CONMAT CSLM 2800: Which Self-Loading Mixer to Buy?
Both these machines load, mix and pour concrete right on site. The AJAX ARGO 4500 carries a much bigger 4.5 m³ drum, runs more engine power, and offers two ways to check batch weight. The CONMAT CSLM 2800 is more compact, steers on four wheels with three selectable modes, and turns its drum faster for quick mixing.
If your projects need large batches and long runs between fuel and water stops, the AJAX ARGO 4500's size and capacity pay off. If your sites are smaller or have tight gates, the CONMAT CSLM 2800's compact build and tighter steering make it easier to work with. See the full self-loading concrete mixer range or read our guide to concrete mixer types.
AJAX ARGO 4500
Pros:
Higher engine power options up to 136 HP for demanding tasks
Larger drum capacity of 4.5 m³ for bigger batches
Higher maximum speed of 28 km/h improves transit efficiency
Greater gradient climbing ability with 21° gradeability
Larger water tank capacity of 800 L for extensive usage
Higher fuel and hydraulic tank capacities for prolonged operations
Significant weight capacity that may imply robust construction
Features both presser transducer and load cell for weighing technology
Cons:
Heavier unladen weight of 8890 kg might affect maneuverability
Larger dimensions may limit accessibility to confined sites
Requires more ground clearance when operating in rough terrains
CONMAT CSLM 2800
Pros:
Features 4-wheel steering with 3 selectable modes for enhanced maneuverability
Electronic weigh batching and spiral blades for efficient mixing
Higher drum rotation speed of 0 to 22 rpm for faster mixing
More compact size may be suitable for smaller or confined job sites
Lighter unladen weight of 6900 kg for potentially better handling and fuel efficiency
Slightly lower overall height, which might be beneficial under certain conditions
Ground clearance suitable for various terrains
Cons:
Lower engine power of 49 HP which may be inadequate for heavy-duty applications
Smaller drum capacity of 2.8 m³ limits batch size
Lower fuel and hydraulic tank capacities, could require more frequent refills
Less powerful water pump capacity at 230 L/min
Pros:
Cons:
Closing Recommendation
Both these self-loading mixers load, mix and pour concrete right on site, so the right pick depends on your job size and site access. The AJAX ARGO 4500 carries a bigger drum, more engine power and bigger tanks, which suits large, high-volume projects with room to work. The CONMAT CSLM 2800 is more compact, steers tighter and mixes each batch quickly, which suits smaller or confined sites where manoeuvring space is limited. So match the machine to your work: AJAX ARGO 4500 for large-volume projects with open space, CONMAT CSLM 2800 for tighter sites needing easy manoeuvring.
