John Craig Contracting specialise in the conversion of standard excavators for low ground pressure work, mainly in the forestry industry and areas where bogs can be found.

They are also used where the need for low ground displacement is required outwith these areas.

John Craig Contracting specialise in these conversions where the undercarriages are widened and extended to allow for this capability, and are the only approved contractor to several forestry excavator hire companies.

Extended excavator tracks are also available.

Ground pressure can be reduced by two thirds with a combination of the extended track frame and the extended tracks.
