Someone forgot to park the Cement Mixer so it falls off the edge with the explosive barrel on the another explosive barrel which kills a guy near.
Then Crane raises up the platform with boxes and guy but the ropes rips off and they start to fall and Dump truck's brakes breaks down,
and driver couldn't brake wheels and Dump truck wrecks/crashes into pile of boxes and everyone dies. Except the Crane operator
