4WD rough-terrain capability — 4.0 tonnes at a 600 mm load center, 30% gradeability and an oscillating axle for the ground without a floor specification.

Where it earns its keep
Ground first: the rough-terrain selection guide orders the decision — surface, grade, ground pressure, then capacity — and the RT40’s specification answers each in turn.
Capacity honestly: 4,000 kg assumes a 600 mm load center, and broken ground adds dynamic forces the flat-yard chart never sees — read the chart, then de-rate by speed on bad ground.
Boundary honesty: where loads must reach over obstacles rather than drive to them, the telehandler wins — the RT versus telehandler comparison draws that line.
Construction sites, farms, lumber yards.
DF30 on prepared pads, RT40 beyond them — the farms and ranches solution shows the split.
Send your duty cycle, loads and site conditions — engineering responds within 12 hours on average.
Cold storage, ports & heavy industry, construction and farms — scenario-first matching across the range.
