CA 2074415
Pipe handling and laying apparatus 1 supports a pipe on holding and support means 2,3 and includes extendible and retractable gripping means 4 having gripping head 4a. The pipe, supported generally within area A, is brought in end-to-end relationship with another pipe to be joined thereto. Gripper head 4a is introduced into the open end of the second pipe and ram piston P of hydraulic ram H is retracted causing legs L of gripper head 4 to pivot into extended positions to grip the interior wall of the second pipe by means of gripper feet F. Further retraction of ram piston P pulls the first pipe into close relationship with the second.
ispositif de manutention/pose de tuyaux 1 comportant un élément de retenue et de support 2, 3, et un élément préhenseur 4 avec tête de préhension 4a. Le tuyau à mettre en place, habituellement retenu et supporté dans la portion A, est abouté au tuyau auquel il doit être raccordé. La tête de préhension 4a est introduite dans l'extrémité libre de l'autre tuyau, puis le piston P du vérin hydraulique est rétracté forçant l'extension des pinces à plaquettes de prise F de la tête de préhension contre la paroi intérieure du deuxième tuyau. La rétraction subséquente du piston force l'emboîtement du premier tuyau dans le deuxième.
