Elevator Counterweight = Half of Elevator Maximum Capacity + Cab Weight
For eg: 10passenger Elevator = 10*80 = 800Kgs
Counter Weight is 800/2 = 400Kgs + Cab Weight
This is just to create a imbalance between Elevator cab and counterweight in order to save power in the drive.

∙ 15y agoThe 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 the main purpose of the counter weight?
it reduces the amount of work needed to lift the bar
What is a block out on beam?
A counterweight.
What is the purpose of the counterweight in an elevator?
counterweight carried by an elevator cable to balance the weight of an elevator cab; the counterweight travels upward when the cab travels downward, and vice versa; usually composed of steel plates stacked within a frame.

Elevator counter weight?
The suitable weight for an elevator counterweight is equal to the weight of the elevator itself. This ensures that the elevator moves smoothly and safely without any jerking or swaying. ESCON Elevators use high-quality counterweights that are perfectly balanced, ensuring a smooth and comfortable ride for every passenger.

Is the elevator today the same elevator that Elisha Graves Otis invented?
The elevator of today is not the same elevator Otis invented although it has many of the same features and works on the same principles. He worked out the counterweight, the pulleys, and the safety brake, or the basic units. It has all been upgraded.
What is the purpose of the counterweight of the forklift?
To aid weight distribution with heavy loads.
How to calculate lifting weight of tower crane?
Lifting weight of the Tower crane depend up on the specifications given.one should lift the given load approximately 18 tonns. Counterweight value is the main value.one can lift the value equal to counter weight value.

How can you calculate the weight of steel present in an elevator including elevator shaft mechanism wires counterweight etc?
It's a relatively straight forward process to calculate the weight of an elevator and the support mechanisms. The car is engineered and constructed with materials of know dimension and density. A calculation is just a mouse click away for a designer. Cable is likewise known; it weights "x" amount per linear foot. The mass of the counterweight is calculated during the engineering phase, and can be adjusted. No magic involved in this. The cable drum, motors, support structure and everything else could be "weighed" by looking at their dimensions and what they are made of. It's engineering, to be sure, but it isn't rocket science. It's standard engineering practice. There is the story of a very highly skilled bunch of welders fabricating a tubular frame for a race car. It weighted just a touch more than they calculated. They forgot to include the weight of the welding rod. Engineers would include that factor, though to be fair, you probably wouldn't want that engineer to do the welding, at least if you were going to drive or ride in it.
What is the acceleration of an elevator if a student stands on bathroom scale in the elevator and the scales reads 836 newtons and the elevator is moving upward?
We have no way to calculate that, unless you also tell us either his mass, or else his weight on motionless ground, like when the scale is on the bathroom floor.
Why are crankshafts counterbalanced?
The weight of the piston, rings, and connecting rod is concentrated out at the rod journal. As the crank spins, it throws that weight around. The counterweight is on the opposite side from the rod journal to offset this weight. This is why when you replace pistons or rods, the crank is rebalanced by adding or removing material from the counterweight.
SUGGEST one advantage of being able to move a counterweight along an arm?
one advantage is that the counterweight can be moved to balance the weight of the mass of what it is working with or carrying
