The heavy construction- and quarrying-suited Cat 352 hydraulic excavator is a 50-tonne class model with variable gauge undercarriage said to offer contractors up to 45% more operating efficiency, up to 10% more fuel efficiency, and up to 15% fewer maintenance costs compared to the model it replaces, the 352F.
Powered by a Cat C13 317kW engine, the Cat 352 has a new long-reach configuration reaching out to 19.6m and capable of digging down to 13.04m - making it ideal for steep slope work. Standard waterproof technology also provides precision excavation down to 4.5m; the optional submarine solution allows you to work down to 20m.
A heavy-duty high-wide undercarriage and extra counterweight provide a stable platform for long-reach digging. Variable gauge undercarriage enables easier transport between job sites when retracted and adds stability when extended.
The next-generation Cat 345 GC 40-tonne class excavator is designed to deliver a balance of performance, reliability, and low-cost operation. The Cat C9.3B 258kW engine-powered excavator can increase fuel efficiency by up to 25% and lower operating costs by up to 30% compared to the 349D2. The new machine also incorporates significant engineering advances for safety and operator convenience.
Fitted with a premium Cat C15 362kW engine, the 70-tonne class Cat 374 offers heavy construction, quarrying and mining contractors high production, two times more structural durability, and up to 20% fewer maintenance costs than the machine it replaces, the 374F.
The 94-tonne Cat 395 offers large quarry and mining contractors up to 10% more production. Like the Cat 374, the Cat 395, which features a Cat C18 405kW engine, comes with two times more structural durability and up to 20% fewer maintenance costs than its predecessor, the 394F.
Speaking about the Cat 374’s and Cat 395's high productivity, Brian Abbott, worldwide product manager for Cat large excavators, said: "A key to production is our new dedicated hydrostatic swing circuit. The circuit enables regenerating swing brake energy and independent management of cylinder airflow. What that means for owners and operators is higher efficiency and smoother, more predictable performance when multitasking with the excavator."
The Cat 352, 374 and 395 machines have three modes of operation: Power, Smart, and ECO. Power mode is maximum power at all times. ECO mode lowers engine speed and cycle times while maintaining breakout force. The new Smart mode takes the guesswork out by automatically matching engine and hydraulic power to digging conditions, reducing fuel consumption and optimising performance. Engine speed automatically lowers when hydraulic demand decreases, further reducing fuel usage.
