    摘要: A pig loader device can include a breech assembly having a chamber body, a ramrod compartment, a breech, and a neck. A ramrod having a push plate, a rod, and a breech plate may be disposed within the ramrod compartment and configured to slideably traverse the ramrod compartment and the breech. In use, the device can be connected to an ancillary pipe via the neck, and a pig may be placed within the breech and aligned be to be slid within the breech and neck upon engagement with the ramrod to facilitate pigging operations of a pipeline. The ramrod may then be forced forward to an extended position, thereby urging the pig through the neck to be seated within the pipe. The device may then be detached from the pipe to enable continued pigging operations.
