How does a weight-driven grandfather clock work? When you “wind” a weight-driven clock, you pull on a cord that lifts the weight. That gives the weight “potential energy” in the Earth’s gravitational field. As we will see in a moment, the clock uses that potential energy as the weight falls to drive the clock’s mechanism.
How much does a grandmother clock weigh?
How much does a grandmother clock weight? Most grandfather clocks weigh somewhere between 100 and 220 pounds, depending on the size. So, we suggest that you measure the dimensions of your clock and research the exact model on the Internet to find an approximate weight. Chances are, it's around 100-150 pounds.

Why are grandfather clock weights not cheap?
Grandfather clock Weights are not cheap mainly because they are so heavy to keep, ship, store, move from here to there. Sure one weight set of three is less than 30 lbs but that adds up quickly in a stack of weight sets. With that said, we don't want to ship these back and forth. It is best to get the right weights the first time. To return these is not an inexpensive or easy task. For example, suppose we charge $30 to ship these. They are wrong for some reason it's now $40 to get it back and another $30 to reship. UPS charges a fee to send a call tag for them to come back. That is $110 to UPS for no reason. So if there are questions, please ask.

To find out how grandfather clocks work, we must first understand why they need to be wound up.
How Does a Grandfather Clock Keep Time?
Mechanical grandfather clocks are powered by an alternating current (AC) electric motor that turns 60 cycles per second (Hertz). The power supply for this type of movement comes from one 1.5-volt D cell battery behind the dial face on some models, while others may have self-contained power cells.
Does a Grandfather Clock Need Electricity?
A grandfather clock has to have electricity to work, but the power supply does not stimulate movement. Instead, the swinging pendulum works with gravity to drive a clock’s gear train that rotates its hands.
