Abstract

A lifting device (10) which consists of a boom supporting part (20), a boom (30), a carriage (40) and a lifting member (50) located in connection with the carriage. The boom is located in the guide rails of the boom supporting part (20) and the carriage (40) is located in the boom's guide rails. The boom (30) can move to both sides of the boom supporting part such that the boom can form a protrusion beam on either side of the supporting part and that the carriage moves simultaneously with the boom and in the same direction as the boom.
