Swivelling bin-filling conveyor

A swivelling bin-filling conveyor comprising a frame including two rear main wheels, and a nosewheel assembly, on which frame there is mounted a conveyor extending obliquely upwardly from said frame, and which is further fitted with a foot resting, in operation, on the ground, said foot being adapted for rotation relative to said frame about a vertical axis, each of said main wheels being adapted to be brought from the normal position of travel into a swivelling operating position, wherein each of the two main wheels includes a separately energizeable drive motor, and suspension members for each drive motor are provided for ensuring that at least in the swivelling operating position only one of the two rear main wheels is driven, and said two main wheels are unlocked in the swivelling operation position when a single one of the two drive motors is energized, said each drive motor being suspended cantilever-fashion by a power output shaft of the motor, spring-biased members being provided which during normal operation prevent the drive motor from being tilted but allow a slight tilting motion of the drive motor as soon as an additional resistance is encountered during a swivelling movement of the conveyor, thereby to actuate an operating member of a switch mounted adjacent the drive motor whereupon said switch switches off the energization of the associated drive motor and switches on the other drive motor.
