PURPOSE: To enable the assembling of pipings safely and labor-savingly by pivotally supporting an arm having a holding mechanism to hold pipings to be capable of taking/releasing pipings at a tip on a rotary frame to bend/expand freely, and providing a positioning robot to position the pipings to an objective position in the piping holding condition.
CONSTITUTION: An upper arm 9 is disposed on a crawler type traveling device 11 through a rotary frame 12 and a base arm 8, and a holding mechanism M is supported at a tip of the upper arm 9. A freely movable positioning robot A is provided as a separate body from the arms 8, 9 to position pipes P1, P2 to each other in connecting the next pipe P1 to be connected to an end pipe of the previously constructed pipe P2 fixed by a stay. This robot A is moved by the holding mechanism M by an operator's operating a remote controller, and tips of the pipings P1, P2 are held by piping holding parts provided at both ends respectively to be positioned.
