Conveyor trolley system

A trolley hanger assembly for suspension from a support rail comprising:

• first and second trolley bodies;
• a roller arm in each trolley body for suspension below the support rail;
• a roller mounted to each roller arm, said roller adapted for rolling movement along the support rail;
• a housing at a lower end of each said roller arm;
• a first shaft with a free end extending from one of said housings and through the other of said housings, said first shaft adapted to provide a pivot axis for an end of a downstream trolley connecting cable;
• a second shaft with a free end extending from one of said housings and through the other of said housings, said second shaft adapted to provide a pivot axis for an end of an upstream trolley connecting cable;
• a third shaft with a free end extending from one of said housings and through the other of said housings, said third shaft adapted to suspend a load supporting attachment therefrom;
• means for releasably attaching said first trolley body to said second trolley body to present an integral trolley unit with said first and second rollers adapted to move along a surface of the rail and an integral shaft housing having said first and second shafts therein with the upstream and downstream cables adapted to respectively extend from said shaft housing in respective pivotable movement about said first and second shafts, said third shaft below said integral shaft housing for suspending a load supporting attachment therefrom.
