Abstract

A transport mechanism maintains a continuous movement by means of two hydraulic cylinders working with alternate power strokes. Each cylinder is mounted on the underside of the moving body and has a piston with a rod attached to a hinged leg. The cylinders are connected to a common hydraulic circuit which controls the cylinders so that when one cylinder is making a working stroke the other cylinder makes a return stroke and the body moves continuously in the same direction.
