Abstract
A vertical reciprocating conveyor has a carriage mounted for movement in a support frame between different designated vertical levels, a door assembly mounted on the support frame for gaining access to the carriage when the carriage is at the one designated level. A visual warning barrier is movably mounted between a raised, inoperative position and a lowered, operative position across a doorway formed in the support frame at the one designated level. The visual warning barrier is automatically moved from the raised, inoperative position to the lowered, operative position upon movement of the door assembly to the open position when the carriage is located away from the one designated level.
