Note: I get commissions for purchases made through links in this post.
By my reckoning, there are 7 Trio sets that have something to do with construction.
There is a Cargo Loader and a similar Construction Loader. You can get a Cement Mixer and a Bulldozer. The Construction Hauler is a semi truck, and the Wrecking Ball Crane will knock down anything you want it to. The Construction Crew set is a small crane and a pair of workmen.
All of these sets were first produced in 2009, the first year that Fisher Price created Trio bricks, sticks, and panels.

The side building can have a red panel that has a breakaway center. If you hit it just right (which can take a few tries) with the wrecking ball, the center will cave in. You can easily snap it back into place later.
