REMOTE CONTROLLED CRAWLER CRANE
May 6, 2020
This is a big crawler crane. I use 3 motors, a medium motor for turning and a large motor for the lifting arm and hooks. There are two hooks, a main hook and an extra hook, which you can switch manually. It also has a system so that the rope cannot fall down when switching. The touch sensor on the fixed arm serves as a safety lock. When the lifting arm reaches its maximum height, an alarm is triggered.
I made my own app to operate the crane. I made it through the free site of MIT App Inventor. Highly recommended to make your own apps.
