A cantilever crane is lightweight and consists of a column, a slewing arm drive, and an electric hoist. The lower end of the column is anchored to the concrete foundation with anchor bolts. A cycloidal pinwheel reducer drives the jib's rotation. The electric hoist operates in a straight line on the jib's I-beam to lift heavy objects.
