A support structure for a receiver (18) which is provided on a hanger arm for supporting an object to be conveyed and the position of which can be switched is simplified. A suspension conveyance apparatus has a long hole (31) provided at a shaft support section for a parallel link (24) that laterally movably supports a receiver (18) and permitting vertical movement of the receiver (18), a spring (28a) for urging the receiver (18) to a direction to pull down the receiver (18) on to a receiver support member (21a), an engagement member (33) provided on the receiver supporting member (21a) side, and two inner and outer engagement recesses (32a, 32b) arranged on the receiver (18) side so as to engage with the engagement member (33) when the receiver (18) is at both inner and outer positions (P1, P2), at a level at which the receiver (18) is supported by the receiver support member (21a). A receiver drive means (42) for laterally moving the receiver (18) between both inner and outer positions (P1, P2) is provided at a receiver switching position in a traveling route of a conveying traveling body (1).
A suspension conveyance apparatus in which a hanger for supporting an object to be conveyed suspended on a conveying traveling body comprising a pair of left and right openable and closable hanger arms which have receivers for an object to be conveyed on lower end inner sides and are pivotally supported at upper end sides thereof so as to freely swing to the left and right, wherein the receivers are switchable in position between inner positions and outer positions in an opening and closing direction with respect to the hanger arms, wherein the receivers are supported on receiver support members on hanger arm sides by parallel links laterally movably between the inner and outer positions, wherein at shaft support sections of the parallel links, long holes which allow vertical movements of the receivers are provided and urging means for urging the receivers in a direction to pull down the receivers onto the receiver support members are provided, and wherein at receiver switching positions in a traveling route of the conveying traveling body, receiver drive means are provided which move the receivers between the inner and outer positions.
