Suspension Crane is developed for clean room only, not occupy space. The effective hanging distance can be improved whichever vertically, horizontally and head. The rail is installed on the ceiling, will not destroy or occupy the space of the working site, can reach the maximum use of the space of the plant. For the working site is more than 12M in span, we use the multi-track (saddle), so neither to enlarge the steel structure of truss nor to increase the height of plant is required. The hanging structure and the H type steel surface is treated by epoxy powder coating, beautiful and safe.
