I think it's called a wrecking ball. If you are referring to a hook block that resembles a ball, then it is know as a headache ball. The official name is the Auxiliary Hook.

The tension in the crane's cable would be equal to the force being lifted, in this case, 1000 N. This is due to the fact that the tension in the cable must match the force being lifted in order to maintain equilibrium.

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.
