Transportation device with a load carrier suspended movably from a rail for a suspended load

摘要

The object of the invention is a transportation device (1) with a load carrier (3) having on its upper side supports (6) running vertically upwards. Rollers (9, 10) are provided on the ends of the supports, with which the load carrier (3) is attached in suspended and movable fashion from a rail (2). The load carrier contains a winch (72) with a belt (82) for suspended loads. A drive motor (60) is provided to move the load carrier along the rail (2). A further drive motor (63) powers the winch (72). The switches (61, 62) for the drive motors (60, 63) are provided with pneumatically operable switching elements (89). The compressed air for the switching elements is generated by a control element (99) operable by hand that is connected to the load carrier (3) via air lines (98). In the inside of the rail (2) are current paths against which carbon brushes (44, 45) are pressed that are arranged staggered in the longitudinal direction of the rail (2). Energy is supplied to the drive motors (60, 63) via the carbon brushes (44, 45).
