Cat boom cuts site damage

One of the UK's first Cat 307 hydraulic excavators with a parallel off-set boom arrangement is helping a Buckinghampshire groundworks contractor reduce site damage during excavation.

The 7.6t machine, supplied by Cat dealer Leverton, is operated by Aylesbury-based Saunders (Southern) - a contractor specialising in house footings and drains.

The boom off-set facility allows changes in the line of house footings to be made without having to reposition the machine. The off-set arrangement, which enables the superstructure to be kept in line with the undercarriage during off-set digging, also permits manhole chambers up to 2.4m wide to be excavated without moving the machine off the centre line of track.
