Abstract
A gear feed system includes a carrier and a mast mounted on the carrier. The mast includes a pair of panels forming opposing sides of the mast along a central axis of the mast. Each of the pair of panels includes a fixed rack attached to an interior surface of the each of the panels. A gear carrier pair includes a gear, a movable rack assembly, and a cylinder. Each of the gear is coupled to one of the panels and each of the gear couples one of the fixed racks to one of the movable rack assemblies (hoist tubes). The cylinder and the movable rack assembly are coupled via the gear wherein an axial movement of the cylinders causes a corresponding axial displacement of the movable rack assemblies.
