Hammer

The Hammer is an Expansion component in the Gravitrax marble run. It is used to provide extra speed to a marble that passes through it.

Function
The Hammer consists of a one-tile, straight track with a weighted lever in the middle. When a marble rolls in from one side and pushes on the bottom portion of the hammer, the top swings down and knocks the marble forward at a high speed. It only works in one direction, however, which is indicated by the arrows on the component. The Hammer can only propel 1 marble at a time; it must be reset to hit another.

This component requires assembly, as it isn’t already put together in the package. The weight at the top of the rod is simply a slightly larger and heavier silver marble.

Obtaining
Only two sets offer this piece, the Starter Set XXL and the Hammer Expansion. There is only one Hammer component in each set.
