D7 Class Dozer HireD7 Class Dozer Overview
A D7 class dozer provides a step up from D6 where additional weight, traction and blade capacity are needed, but where a D8 may be larger than required. It is useful for heavier civil works, larger platforms and more demanding pushing applications.
This class performs well on bulk earthworks, mine infrastructure, haul road support, embankment shaping, roadworks, quarry support and projects where a D6 may be working too hard. It can also be useful where ripping support is required, subject to machine configuration.
Project Plant Hire can assist with D7 class dozer hire for medium-heavy sites that need stronger production without moving into the cost and logistics of very large dozers.
