Problems solved by technology

The counterweight is an important part of the weight balance system. Due to the particularity of the elevator operating environment, the counterweight needs to have strong toughness, strong pressure resistance, strong impact resistance and strong corrosion resistance. Heavy blocks perform worse in these properties

Description

technical field [0001] The invention belongs to the technical field of elevator assembly and application, and in particular relates to a steel pin molded elevator counterweight and a preparation method thereof. Background technique [0002] Counterweights are weights used to add their own weight to maintain balance. Elevator counterweight is also called weight balance system. The main function of this system is to relatively balance the weight of the car. During the operation of the elevator, the weight difference between the car and the counterweight can be kept within the limit to ensure the normal traction transmission of the elevator. The counterweight is an important part of the weight balance system. Due to the particularity of the elevator operating environment, the counterweight needs to have strong toughness, strong pressure resistance, strong impact resistance and strong corrosion resistance. Heavy blocks perform poorly in these properties. [0003] Based on the ...
