Elevators are vertical transport equipment used mainly for lifting and lowering loads. Roll and chain conveyors for e.g. pallets with load of different dimensions transport are mostly raised on elevators.
Depending on the load dimensions or spatial restrictions around the transport line, it can be necessary to change the load movement route and avoid obstacles. Therefore, the load is lifted or lowered to the desired level and transported further on by another transport line. Elevators can combine two or more transport line levels — depending on the needs and spatial conditions.
