Thank you for your interest!
1. The flatbed truck was built in 1999 and revised this year. The gray lever is
a manual pump. It works very easy, but because of the increased mechanical
advantage, it takes longer to pump.
2. The plane is from 2001. The joystick moves forward/back to move the
elevator, and side-to-side to move the ailerons. I must confess the green pieces
are mega bloks. (there are a few mega bloks or tyco blocks in between the
pistons in the dump truck.)
3. As for the dozer, the antenna (levers) switch each track from forward to
reverse. I could not figure out how to make a hydraulic drive with legos, so
this was the next best alternative. Each track has a forward and reverse gear.
4. The roller tires are from the "Super Car"(1994) and covered with sheet metal.
5. The black lever on the track-hoe is a switch for a transmission that either
connects the engine to the tracks or swivels the body. I eventually want to add
the same drive system as the dozer to the track-hoe, but it will be hard to do.
Every model has a piston engine, the crane is being finished, and a telehandler
is being added.
