A pullhead includes a housing that has a first end and a second end. The housing is separable between a first body and a second body. The first and second bodies are pivotally coupled at a joint and the first and second bodies together define an interior pocket of the housing. The interior pocket has an interior pocket width. The pullhead head includes a pulling feature at the first end. The interior pocket includes an interior retainer flange that has an inner width and is disposed within the interior pocket. The inner width is less than the interior pocket width. The first body and second body are pivotable relative to each other around an axis at the joint that is transverse to a pulling direction.
A pipe pulling technique where an adaptor is attached to the end of the pipe prior to the pipe being pulled underground, for example through a drilled hole. Attaching the adaptor to the pipe end prior to the pipe being pulled underground is faster and reduces danger to workers compared to the conventional process of attaching the adaptor to the end of the pipe after the pipe has been pulled underground.
F16L 3/10 - Supports pour tuyaux, pour câbles ou pour conduits de protection, p. ex. potences, pattes de fixation, attaches, brides, colliers entourant pratiquement le tuyau, le câble ou le conduit de protection fractionnés, c.-à-d. à deux éléments en prise avec le tuyau, le câble ou le conduit de protection
