The invention discloses a novel pressing-method bolt-free integral dropper and a manufacturing method thereof, and a contact line and carrier cable dropper wire clamp, and relates to an electrified railway overhead line system erecting device and a manufacturing method thereof. The novel pressing-method bolt-free integral dropper comprises a dropper wire, a contact wire dropper wire clamp and a carrier cable dropper wire clamp, the contact wire dropper wire clamp and the carrier cable dropper wire clamp are connected to the two ends of the dropper wire, the contact wire dropper wire clamp is connected with a lower heart-shaped retaining ring of the dropper wire, and the carrier cable dropper wire clamp is connected with an upper heart-shaped retaining ring of the dropper wire. And the indentations of the upper and lower crimping pipes of the dropper wire are parallel to the wire body at the crimped part. The novel pressing-method bolt-free integral dropper is long in fatigue life, and the fatigue life can reach more than 350,000 times (the standard is specified as 2,000,000 times).
