FIELD: construction.
SUBSTANCE: invention relates to the construction and repair of pipelines and is used for cutting and tying in of "coils", connecting parts, plugs, shut-off and control valves. Claimed device includes a support structure with its fastening elements to the base, a pipe gripper, power elements for moving and fixing the pipe gripper. Support structure is immovably fastened to the base. All power elements for moving and/or fixing the pipeline are installed directly between the pipe gripper and the support structure and/or through the intermediate elements. Pipe gripper consists of a flexible element, for example, a sling, if necessary reinforced with rigid elements, or from several rigid elements, hinged and/or with flexible elements fastened together. Number and/or shape of the rigid elements are determined by the pipe diameter. Device comprises at least one force sensor.
EFFECT: invention makes it possible to simplify and lighten the device design, reduce the number of its elements, simplify and accelerate the installation and removal, allows the device to be used including on weak grounds.
