(KHNL) - Aaron Yamashiro's livelihood depends on hauling equipment like this towering excavator.
His family's trucking company has been around 50 years.
He says Tuesday's accident involving a similar excavator was a huge wake-up call.
"Wow! We couldn't believe it happened," said Yamashiro with Ed Yamashiro, Inc.
Here, the boom of the excavator is lowered.
But he says the next step could have prevented an accident.
"When you tuck the hammer under, you bring boom down here," explained Yamashiro.
He said, "That's why he didn't tuck it under all the way underneath see top portion of boom is more exposed."
Yamashiro's drivers haul 3-4 types of oversized equipment a day.
They're required to apply for a permit.
He said, "It's something we have to do it's just like getting up and brush your teeth you have to get a permit."
He says the permitting process is helpful since overhead structures are different heights.
The process also maps out the safest routes.
"If too big for them then they refer us to engineers where can or cannot go," said Yamashiro.
Yamashiro says if there were any lesson learned this week, it's that you can never be too careful.
