  • the two expandable clamp members are locked together in a tensile manner. Due to this tension-proof locking, a multi-part clamp with a known function is created, which can be closed by at least one clamping cylinder in order to produce the tension between the pipe drawing machine and the drill pipe required for pulling the drill pipe.

Abstract

Une machine pour extraire un tube de forage de pieu de fondation apres le betonnage, est composee d'un collier de serrage en plusieurs pieces (2a a 2f) avec cylindres de serrage (9) et d'un cadre de base fourchu. Celles des pieces de serrage (2c, 2d) qui ferment l'ouverture de la fourche du cadre de base, sont ecartables au moyen de doubles cylindres de fermeture (16, 17) de maniere que la fourche soit completement libre et que la machine puisse etre mise lateralement en position de travail par rapport au tube. Pour fermer le collier de serrage les pieces de serrage ecartables (2c, 2d) seront remises en place et verrouillees solidement ensemble par un boulon de verrouillage (24).
