The 2-ton semi-gantry type clean room crane is a movable semi-gantry crane used in the clean room. Cleanroom semi-gantry cranes are used in precision machinery industry, electronic industry, semiconductor, integrated circuit, aerospace industry, high-purity magnetic products, atomic energy industry, chemical industry, light industry (CD, tape, film production), LCD (liquid crystal glass), computer hard disk Head production and other industries! The difference between the clean room semi-gantry crane and the conventional gantry crane is that its legs have a height difference, which can be determined according to the civil engineering requirements of the site. One end beam of the clean semi-gantry crane walks on the crane beam, while the other end beam walks on the ground, making full use of the columns and corbels of the workshop, saving production space and effectively improving the utilization rate of workshop space, so it is widely used in modern production.
