Cat D9G at EM wd 2011 - IMG 0517

Caterpillar D9G at the East Midlands and Link Club Working Day

The Caterpillar D9G was a 385 hp (287 kW) crawler tractor built by Caterpillar Inc. in the USA from 1961 until 1974. The Caterpillar D9G superseded the Caterpillar D9E and was replaced by the uprated Caterpillar D9H.

For many years these were the biggest machines to be regularly found in the UK mainly operating on opencast sites and quarries pulling towed scrapers or with a bulldozer blade stripping overburden & push loading Motor scrapers. The Twin-engined Euclid Dozer was bigger, but very rare.

Due to the size and weight few examples are in preservation in the UK as most were worked to death or exported when newer machines cam in or a downturn rendered them surplus to requirements and they were sold off at auction.
