A hanger device for a trolley conveyor including a carrier comprising:
- a pair of opposed hanger arms approximately U-shaped when seen sideways, said hanger arms being openably suspended from said carrier for loading or unloading an article;
- each of said hanger arms including a front hanging member, a rear hanging member, and an extensible horizontal member connected at its opposite ends to the lower ends of said hanging members, said extensible horizontal members being positioned in and extensible in the same plane;
- means for adjusting the relative positions of said front and rear hanging members on said carrier longitudinally of said hanger device;
- said horizontal member being provided with article support members attached to its front and rear portions and projecting inwardly therefrom.
A hanger device for a trolley conveyor comprising:
- a carrier;
- two parallel suspending rods rotatably attached to said carrier and extending longitudinally thereof;
- a hanger arm suspended from each of said suspending rods, said hanger arms being approximately U-shaped when viewed from the side;
- each of said hanger arms comprising front and rear hanging members each having at its upper end a ring fitting around said suspending rod, the lower ends of said front and rear hanging members of each hanger arm being connected by a horizontal member extensible in the same plane, and being provided with article support members projecting inwardly therefrom;
- said ring of said front hanging member and said ring of said rear hanging member being axially movable on said suspending rod with respect to each other;
- said horizontal member comprising a front tube having a front end fixed to the lower end of said front hanging member, a rear tube having a rear end fixed to the lower end of said rear hanging member, and an intermediate tube fitting around the rear end of the front tube and the front end of the rear tube to interconnect these ends and being fastened to said tubes so that at least one of said tubes is insertable into and withdrawable from said intermediate tube;
- a stopper provided on said carrier for restraining each of said hanger arms from pivotally moving inward, said stopper comprising two parallel projecting members extending sidewise from said carrier and a bearing member interconnecting said two projecting members;
