A headache ball is a heavy steel ball used to provide ballast on the hook end of a crane hoist rope. Typically some larger cranes have an auxiliary/secondary hoist that can lift light loads but at a much faster speed than the main hoist. A hoist rope needs ballast so that the rope remains tight and does not whip (ballast normally provided by the weight of the hook on the main hoist).
Because of the fast speed of these secondary hoists and the common failure of older limit switches it was not uncommon for ropes to be over-wound causing this ballast ball to strike the crane jib and become separated from the rope, dropping to the ground.
A crane with a secondary hoist is not normally referred to as a "headache ball crane" but this might be what is meant.

How do you beat the bulldozers on twisted thicket?
As the dumptruck, bulldozer, and wrecking ball roll by you, put on the amulet and become a gremlin (green) to chase them down. Jump onto the wrecking ball crane and become a troll (yellow) to push the crane to over the bulldozer (right). Become a dryad and fly to the top of the crane. Push the lever that releases the ball. Become a troll and jump down to the bulldozer. Pick up the ball and toss it onto the dumptruck. Now that the worker guard is gone, become a gremlin (green) and run to the truck. Climb onto the fuse box and become a troll to destroy it. The construction director will give you the orb shards and surrender. (see related questions)
