A lot of truck cranes have gradual-travelling ability (a couple of miles for each hour) though suspending a load. Excellent care must be taken to not swing the load sideways within the direction of travel, as most anti-tipping balance then lies inside the stiffness on the chassis suspension. Most cranes of this type also have shifting counterweights for stabilization beyond that provided by the outriggers. Hundreds suspended directly aft are one of the most stable, because almost all of the fat on the crane acts to be a counterweight. Manufacturing facility-calculated charts (or electronic safeguards) are used by crane operators to ascertain the utmost Safe and sound masses for stationary (outriggered) operate together with (on-rubber) masses and travelling speeds.
