These systems, in which trolley hoists are used (PCH – PCH Flat – HDH – HTH Series) can operate more stably than single girder overhead cranes. Beacuse of the span and tonnage which can be designed up to the maximum levels and the difference in maximum lifting height, they are preferred more often than single girder overhead cranes.
