A movable body movable on a given path is provided with a support section for an object to be carried. Supports for supporting an object to be carried are disposed in the lower portion of the support section on the right and left sides thereof such that a support position can be changed. The given path is provided with a changer positioned between the right and left supports for changing the support position provided by the supports. The movable body is moved until it is stopped with the now-empty support section opposite the changer. The changer is then actuated, thereby changing the support position provided by the supports. Thus, different kinds of objects to be carried can each be stably supported. The common changer simplifies the configuration and operation and enables the support position provided by the right and left supports to be changed quickly and reliably.

Suspension conveyance system

A conveyor trolley with a pair of wheels rolling on a flat upper face of an upper end rail portion of a guide rail, one wheel acting as a drive wheel and attached to an output shaft of a speed-reducing unit mounted on a trolley body movably supported on the guide rail, and a motor for driving the output shaft via a speed-reducing mechanism in the speed-reducing unit, the trolley having a collector unit for supplying power to and communicating control signals with the motor, guide rollers for laterally binding and positioning the upper rail portion and a lower rail portion of the guide rail, a wheel securing unit disposed between an annular concave portion defined in a boss of the drive wheel and the output shaft, the wheel securing unit including an outer ring, an inner ring having a wedge-shaped cross section to be engaged into the outer ring and a tightening member for securing the wheels to the output shaft by reducing an inner diameter of the inner ring and by enlarging an outer diameter of the outer ring, the trolley further having a clutch removably disposed between the output shaft of the speed-reducing unit and a final rotary member of the speed-reducing unit loosely mounted on the output shaft and an operational lever attached to the clutch for engaging and disengaging the same.
