Description

field of invention

[0001] The present invention relates to an elevator counterweight, and more particularly to an elevator counterweight suitable for achieving the desired balance of an elevator typically designed to move up and down. Background technique

[0002] Counterweights suitable for achieving specific balance in conventional elevators, press machines, flywheels of prime movers, various machines and equipment are made of cast steel or have a viscosity of 7.6 to 7.8 made of cast iron. When melting and casting the weights, the loss of steel may increase due to contamination or technical problems of engineers, thus complicating the production line. The corresponding equipment and the total cost required for the equipment increase accordingly. As a result, the price of the counterweight product increases, leading to an increase in the cost of the system.
