How Do Forklift Trucks Work
A forklift works by having a part that lifts the load and a
part the holds the forklift down.
The mast does the work of raising and lowering what is being
moved by the forklift. Attached to the mast are forks or other
attachments. Usually the mast is hydraulically operated.
Sometimes it is chain operated.
The counterweight is what holds the forklift down while it
performs it's lifting and lowering of the load. This is
attached to the rear of the forklift. It is a heavy cast iron
mass. On electric forklifts, sometimes the batteries are part
of the counterweight.
The purpose of the counterweight on a forklift is to balance
the load being lifted.
