Looking after the operator
Caterpillar set new standards years ago with the Cat Comfort Seat but that does not stop them making further refinements. More space has been created by use of electronic controls and integrated digital display units which enable the operator to sit in a more comfortable position.
The new Cat excavators have improved cabs with more space and visibility. A larger LCD monitor is simpler to use and easier to read
New cab seals and a new roof-lining material to lower in-cab sound levels add to the level of comfort. The LCD monitor is larger and simpler to use - a positive move to encourage operators to fully use the settings available. For most operators, the simpler the better.
Three new minis finally arrive
Originally shown at Samoter 2011 as prototypes, the 300.9D, 301.4C and the 302.7 CR with operating weights of 935 kg, 1515 kg and 2670 kg are now available.
Tthe Cat 300.9D, 301.4C and the 302.7 CR have arrived
All three models are manufactured under the special agreement with Wacker-Neuson.
The 300.9D, at just 935 kg, is the smallest machine in the Cat range. Just 730 mm, it is capable of driving through a standard doorway, providing easy access to the most confined job sites.
This model is powered by a water-cooled three-cylinder Yanmar 31NV70 diesel engine producing 13.7 kW. The extending undercarriage and fold-out dozer blade increase stability enabling a digging depth of 1,731 mm and a maximum excavation radius of 3,074 mm.
Caterpillar’s work tool division will be introducing a new H25 compact breaker specifically to work with this smaller machine. Auxiliary hydraulic lines with quick disconnect fittings are supplied as standard.
With an operating weight of 1,325-1,515 kg, depending on specification, the Cat 301.4C fits into the line-up below the current 301.8C, extending choice in the popular 1.5 ton market.
The 300.9D, at just 935 kg, is the smallest machine in the Cat range.
The machine is available with a choice of cab or FOPS/TOPS canopy, and with standard or extending width undercarriage. Power comes from a 17.9 kW Yanmar 3TNV76 engine and the machine boasts a maximum bucket breakout force 16.0 kN and a stick force of 7 kN. Maximum digging depth of 2,240 mm and reach at ground level is 3,640 mm.
Weighing 2,577 kg with a canopy or 2,670 kg with full cab, the 302.7D CR is the lightest Cat compact radius model, making it easy to transport for a rental company or contractor. Powered by the same 17.9 kW engine as the 301.4C, the machine has a load sensing hydraulic system, providing a maximum bucket force of 22.5 kN and a maximum stick force of 21.76 kN.
More excavators from New Holland
New Holland adds two models to the ones launched earlier this year, expanding the C Series to four models ranging from 21 to 31 tons. The 21 ton E215C and 25 ton E245C carry on the productivity and fuel saving features of the series.
The company say that the new models deliver 10% more productivity as a result of the additional 15 hp power from the latest engine. By optimising the hydraulic system to the engine performance, New Holland say that a saving of up to 10% in fuel is possible.
Both models use Selective Catalytic Control (SCR) technology, which optimises the combustion process for maximum efficiency, allowing the 6-cylinder common rail engine to focus entirely on generating power.
This solution, developed by FPT Industrial to meet EU Stage 3B emissions regulations, relies on an after-treatment system that breaks down the NOx into nitrogen and water through a chemical reaction with AdBlue Diesel Exhaust Fluid (DEF), while Particulate Matter levels are minimised by the high combustion temperatures.
The new model feature the EVO cab for good all round visibility made possible by full size right side window and a rear view camera fitted as standard.
nNw EVO cab on latest excavators which feature upgraded dampers tp cut in vibration levels lower by as much as 30% when travelling and 50% when digging.
New dampers result in vibration levels lower by as much as 30% when travelling and 50% when digging.
The two models have a maximum bucket capacity of 0.31 m³ and a maximum digging depth of 7,170 mm. Maximum forward reach is 10,350 mm and maximum dump height is 7,170 mm (but will vary according to boom configuration)
