For transportation of cylindrical form items with the internal cavity (e.g. pipes, coils, etc) and considerable bulk (less or equal to 300 kg), mechanical gripper devices are used. These gripper devices provide high specific pressure on the surface of the item transported and this leads to mechanical deformation and disruption of the product integrity. Elaboration of the gripper device which eliminates any mechanical ware damage throughout all the technological process of its transportation is the topical issue of today. Application of the structure of multi chamber gripper device with a non expandable casing let us lower specific pressure on the surface gripped and also extend hoisting capacity. Device consists of two correlated drives, i.e. chamber gripper and two membrane drive of its transportation. This technical solution allows to keep the product with minimal power influence and to provide smooth erection of the article on the working surface. Efficiency of the chamber gripper aggregate module is corroborated by computer modeling and experimental researches. The discrepancy between researches and machinery experiments is 10% and this does not exceed the permissible rate of output.
