Gradall Discovery Excavator
Gradall Industries has introduced 2 new Discovery Series hydraulic excavator models – D172 and D174 – that are bigger, more muscular and more productive than the previous D152 and D154 models. They benefit from a 36% increase in horsepower as well as greater torque to increase travel speed, hill-climbing capability and overall productivity. Both models were developed in collaboration with Freightliner. The Discovery D172 has 2-wheel-drive while the D174 is a 4-wheel-drive machine. Both feature a versatile telescoping, full-tilting boom, able to rotate attachments 220°. The low-profile boom design also allows Discovery Series models to work productively under bridges and in tunnels where miniexcavators and tractor loader backhoes cannot operate. Their 300 hp Cummins 6.7 l engines enable them to travel to jobsites at highway speeds.
