Caterpillar covers heavy-duty sector

CATERPILLAR has produced a range of heavy-duty demolition versions of its 300 excavator weighing from 20 tonnes to 90 tonnes.

The machines can be matched with standard or straight demolition booms and a selection of reinforced sticks; a Super Long boom is offered for larger machines. An auxiliary hydraulic circuit is fitted with the B-series 300 models, which provides increased hydraulic power for a range of attachments. Cat has 40 different demolition attachments for excavators and loaders.

Special markets manager Marilyn Murphy forecasts an upward trend in the size of excavators, beyond the current largest 90-tonne machines. She said: 'It's easy to see why they have become so popular for demolition. They are safer, easier to operate and much more controllable than any other type of demolition machine.'

Cat believes that the key design features include a purpose-built boom to optimise strength, lift capacity and reach; reinforced upper frames, a heavy-duty undercarriage, a cab with good upward visibility and impact resistant glass; and body protection.
