ABSTRACT:
A pipe-driving apparatus has a support body with tubular components for accommodating the cylinders of hydraulic rams. The body has a plurality of location members with jaws selectively engageable with the outer end of a pipe section to be driven.
These jaws can move radially inwards or outwards of the pipe section and can thus selectively couple the support body to the pipe-section so that the rams can be extended against an abutment to move the pipe section longitudinally.
During use of the apparatus the support body and the cylinders of the rams are substantially entirely located within the pipe section.
