An overhang rail transport system, comprising: • a first processing section comprising multiple spaced apart first carriers (15, 15') for conveying carcass parts of a four legged slaughter animal, where each of the first carriers comprises a free end (22, 41') for extending through an opening in a leg part of one of the carcass parts causing the carcass parts to be at least freely hanging, • at least one second processing section comprising multiple spaced apart second carriers (40, 42) where each of the second carriers comprises a free end (41, 43) for engaging with the leg part of one of the carcass parts causing the carcass part to be at least freely hanging, wherein the overhang rail transport system further comprises: • a transfer zone positioned between the first processing section and the at least one second processing section, • a control device for automatically controlling the movement of the first and the second carriers so that upon arrival at the transfer zone the first and the second carriers are synchronized in movement characterized in that: • a first carrier amongst the first carriers moves in a first direction carrying the carcass part through the opening in the leg part and at least one empty second carrier moving in a second direction meet with their respective free ends (22, 41) facing each other, the transfer zone being arranged such that during movement of the first and the second carriers: • the relative horizontal distance between the free end of the first carrier and the free end of the second carrier decreases, • the second carrier engages with the carcass part, followed by • the weight of the carcass part load being transferred from the first carrier to the second carrier. • a first processing section comprising multiple spaced apart first carriers (15, 15') for conveying carcass parts of a four legged slaughter animal, where each of the first carriers comprises a free end (22, 41') for extending through an opening in a leg part of one of the carcass parts causing the carcass parts to be at least freely hanging, • at least one second processing section comprising multiple spaced apart second carriers (40, 42) where each of the second carriers comprises a free end (41, 43) for engaging with the leg part of one of the carcass parts causing the carcass part to be at least freely hanging, • a transfer zone positioned between the first processing section and the at least one second processing section, • a control device for automatically controlling the movement of the first and the second carriers so that upon arrival at the transfer zone the first and the second carriers are synchronized in movement characterized in that: • a first carrier amongst the first carriers moves in a first direction carrying the carcass part through the opening in the leg part and at least one empty second carrier moving in a second direction meet with their respective free ends (22, 41) facing each other, the transfer zone being arranged such that during movement of the first and the second carriers: • the relative horizontal distance between the free end of the first carrier and the free end of the second carrier decreases, • the second carrier engages with the carcass part, followed by • the weight of the carcass part load being transferred from the first carrier to the second carrier. • a first carrier amongst the first carriers moves in a first direction carrying the carcass part through the opening in the leg part and at least one empty second carrier moving in a second direction meet with their respective free ends (22, 41) facing each other, the transfer zone being arranged such that during movement of the first and the second carriers: • the relative horizontal distance between the free end of the first carrier and the free end of the second carrier decreases, • the second carrier engages with the carcass part, followed by • the weight of the carcass part load being transferred from the first carrier to the second carrier. • the relative horizontal distance between the free end of the first carrier and the free end of the second carrier decreases, • the second carrier engages with the carcass part, followed by • the weight of the carcass part load being transferred from the first carrier to the second carrier.
