A heavy-duty push chain, belonging to the field of push chain technology, includes several chain links connected sequentially by pins. Each chain link includes a set of opposing composite chain plates. The composite chain plates include push chain plates and tension chain plates connected together by rivets. When the push chain plates of adjacent chain links mesh with each other, the push chain is in a straight pushing state, with the push chain plates transmitting the thrust. When the push chain is in a tension state, the tension chain plates transmit the tension. This invention can provide tension like an ordinary chain, and can also exhibit rigidity in a straight state, thereby transmitting thrust. By fixing the tension chain plates and push chain plates to form composite chain plates, and forming first and second chain links through different combinations of composite chain plates, the push chain is formed through further combination and connection of the first and second chain links. This effectively solves the problem of mixed forces on the chain plates of existing push chains, making it difficult to conduct targeted observation, research, and optimization.
