When you have a range of tracked excavators as wide as Caterpillar does, it is unsurprising that their, ‘small’ crawler excavator range starts with an operating weight of 13.8 tonnes with the 313. This range extends to the mighty CAT 395 with an impressive operating weight of 94 tonnes and a maximum digging depth approaching ten metres. These uge machines do not play such a large role in the UK market – the most common CAT crawler excavators in the UK market weigh in at the 20-30 tonnes operating weight, like the CAT 320 or 330. If you need to work in tight areas, then check the model names for the ‘CR’ – this means ‘Compact Radius’ which means that the machine does not swing out so far from the edges of the tracks. If you are looking for smaller versions than the caterpillar tracked excavators for sale on these pages, then check out the CAT mini excavators category.
