DevinThe space elevator, which is a concept and is not something that is being built, has a counterweight at the "top" end of the cable. It is the "anchor" to which the cable that goes down to the earth is attached. The weight will vary. It will be a heavy as we can make it. Heavier is better, and the heavier the counterweight (assuming an appropriate cable is found), the more we can lift in a single load. Initial proposals included capturing an asteroid and using that. But this is a technological impossibility with current knowledge. Using a space station may work. And initial "loads" lifted into space could be used to increase the mass of the counterweight. The concept is a challenging one, and the key to actually building one is to find a light and strong enough "cable" to anchor to the earth and to the space platform outside the earth's atmosphere. Carbon fiber is being looked at. Possibilities continue to arise. A link is provided below.

How do elevators work?
When you step into an elevator and close the door, you had passed through two doors and are now standing in a box (or the elevator car) inside a vertical passageway (called the lift shaft). One door is in the walls of the floor that you got off, and the other door is part of the car itself.Inside the shaft are hoisting cables attached to the top of the car. The cables run over a sheave (pulley) connected to an electric motor at the top of the shaft. The other end of the cables is connected to a heavy steel weight called a counterweight. When the car goes up, the counterweight goes down; when the car goes down, the counterweight goes up.How the counterweight reduces to a minimum the power needed to operate the elevator ...Weight of counterweight = Weight of the car + (about) ½ of its maximum passenger loadSo when the elevator operates, it needs power only to lift the weight of the extra passengers in the car; the rest of the weight is balanced by the counterweight.
An elevator lifts five passengers 30 meters in 24 seconds the power is 15000 watts what is the total weight of the elevator and passengers?
12,000 N, since force is equal to weight in this situation
An elevator has a weight limit of 350lbs a box of machine parts weights 25lbs which inequality best describes the maximum number of boxes b that the elevator can hold?

What is a block out on beam?
A counterweight.
What is the main purpose of the counter weight?
it reduces the amount of work needed to lift the bar
