Bulldozer in 1970: Bulldozer milestone 6

Operators choose variants for duty cycle first — peak brochure numbers rarely decide the fleet mix. Structure, propulsion, energy store, control loops and human interfaces jointly set what a Bulldozer can promise on a timetable. Safety envelopes — crash structures, redundancy, certification — are part of the product, not an optional sticker.

Status, film portrayals and workplace lore shape how people judge a Bulldozer before they ever read a spec sheet. Rituals of boarding, maintenance and naming rights turn hardware into belonging — or resentment — in different cities. Capex, energy, crew and infrastructure fees decide whether a Bulldozer programme expands or stalls.

Regional makers and import rules create parallel markets that look similar in photos and diverge in spare parts. Bulldozer engineering is a stack of structure, energy conversion, control loops and certified envelopes inside the road atlas. This page maps how loads travel, how power becomes motion, and where the hard limits sit.
