Merli concrete pumping Mack terrapro putimizer hydraulic concrete pump truck washing off concrete

After I dropped my brother off to school saw a concrete pump trucks arm high up in the west end of the school, so I decided to film it and my original plan was to film the concrete mixer truck in ladera heights apartment but I prefer these bigger pumps better! Workers at the front gate unloading a semi truck they let me in but I had to be careful not to get into peoples way, finally got footages of concrete pump pumping concrete on each area but one of the project managers came around and he wanted to know why I was around the site, “I told him I just want to film the concrete pump!” But he wanted me to get out since I am not part of the company and when the truck was about to fold he said “take your last photo and leave!” So I had to film the arm lowering from far and later the truck was reversing leaving the site
