Dressta specialized its wheel loaders and crawler dozers to be able to cope with the adverse weather and extreme temperature diversity. This was achieved by equipping the machines with an air conditioning system for summer and its ‘Arctic Package’ SFR for winter.
Tough climatic conditions were coupled with equally demanding ground conditions. The Dressta machines had to cope with exceptionally hard rock that attains 9-11 units in the 12-unit Protodiakonov scale.
The necessity to build these service roads often meant the machines and their operators were working on the edge of a several hundred-metre abyss. Such fine margins required optimal machine balance and stability with no room for error – an application that Dressta crawler dozers are renowned for.
