ABSTRACT:
The automatic leveling and synchronization system for raising and lowering a counterweight includes at least a primary and secondary cylinder connected in series hydraulic communication. The primary cylinder includes a first rod connected to a first piston, and the first rod is attached to one end of a counterweight. The secondary cylinder includes a second rod connected to a second piston, and the second rod is attached to another end of the counterweight. A surface area of a bottom of the second piston is set equal to a surface area of a top of the first piston.
