PSA: That old school hand signal chart from the 90s is still dead on
Found a faded copy taped inside a cab on a job in Kansas City last month. Skeptical at first, thought it was just nostalgia. But the line about the 'extend boom and lower load' signal being two separate moves? Saved us from a near miss when a new spotter got his signals crossed. Anyone still using those paper charts or is it all radio now?
