An engagement chain type hoisting and lowering device is disclosed, having a hoisting and lowering table attached to the upper end of two or more pairs of hoisting and lowering driving engagement chains. A driving motor drives two pairs of hoisting and lowering sprockets which, in turn, raise or lower two pairs of hoisting and lowering driving engagement chains. By arranging two pairs of hoisting and lowering driving engagement chains on two opposed sides of the hoisting and lowering table, buckling of the hoisting and lowering driving engagement chains is suppressed, resulting in stable hoisting and lowering operations without slippage of articles on the hoisting and lowering table, and chain endurance is improved. The device is designed so that the lowest position of the hoisting and lowering table can be lower than the height of the peripherally located driving motor, for ease and safety of operation and maintenance.
