Simulators where you decide and see the consequence: the generator that trips, the overloaded bucket, the excavator waiting for a truck, the trench that caves in. Every number comes from the site's spec sheets and tables, and whatever depends on your site is marked as an assumption.
Start the loads
Why does the generator trip if it was enough while running?
Power up the site item by item and watch each motor's peak against the generator's rating. The largest motor's start decides the size.

How much does what you lift weigh?
The same machine with wet sand, rock or topsoil: bank and loose density, swell and the big bucket that exceeds what it can take. Weigh your own material.

How many trucks does your excavator need?
Passes per truck and one hour on site in seconds: too few trucks and the excavator stands idle; too many and they queue. One tap shows the balanced fleet.

Try itTrench slope
From what depth does an unprotected trench cave in?
Pick the soil and depth and dig. Without a slope or shoring the wall comes down; one tap applies the standard's slope and you see how much extra earth it moves. The three soils, side by side.

Does your loader have enough flow?
Mount any of the 30 attachments on any Bobcat loader, with Bobcat's official compatibility chart: whether it fits, needs high flow and whether your load fits. One tap shows the smallest machine that runs it.
