Significant changes in design concepts of heavy-duty vehicles have been made; vehicles have increased in size, multiple power principle is used in scrapers, and articulated concept is applied to material-handling vehicles; payload of earthmoving dump-trucks has been increased to 120 tons, bowl capacity of scrapers to 50 yd, and capacity of loaders to 15 yd; mechanical shift control systems are being replaced with other system types, controlled by air, hydraulics, or electricity; new electric shift control system by General Motors, Allison Div is easily adaptable to new vehicle concepts and offers additional advantages of shift inhibiting and increased transmission durability.
